Mup.sys? Hangs but not? Wha's happening?

If you have read any of my problems, (computer hangs all of the time) then you should know all about the problem. I booted it today, (still not fixed) into safe mode. As you might know, Windows XP safe mode boot tells you whats going on. When it got to Mup.sys, it seems to have stopped responding. None of the lights on the keyboard work. Nothing changes on the monitor. BUT, I can hear the clicking of the hard drive, and the little hard driver light is on.

I'm aware of this prob! Have just bought a skeleton box and added a hard drive from my old box. It doesn't hang after MUP.SYS - simply reboats and around we go again. Two ideas 1) Have you added any PCI stuff to your box? If so - take it out and try again 2) It's possibly something to do with security so you could try booting off your XP disc? This might make it clear that you are a legit user. Try computing.net for more details. I'll let you know how mine works out. Rgds Mike

Thanks. It turns out, I've gotten two defective processors. I'm getting a new one, but I don't know when FedEX will deliver. You know them. Their policy should be "Handle with care or fragle=Use it as a baseball. Slower is better" It seems that way at least. Heck, it could be. Ha ha. Thanks.

I have encountered this issue with Mup.sys merely by changing the hard drive with windows XP on it to a system that is identical in every way.

MUP.sys - Multiple UNC provider...x heres a fix posted on another site Start the Recovery console or.. Start the computer with the boot disks or Windows CDROM After the Welcome to Setup dialog box appears, press R to repair, and then press C to start Recovery console. Choose install Windows and log on as Administrator. At the command prompt type "disable Mup.sys" "MUP stands for "Multiple UNC Provider" which assists Windows in locating resources when more than one redirector is on a machine such as "Microsoft Client for Microsoft Networks" and the "Novell Client for Novell Netware". When a connection to a server is requested it does not know if the request is to a Novell server or an NT server. It will start looking for the server with the primary protocol on the primary requestor and then continue looking for the server on each protocol bound to each redirector until the server is found." Restart the computer and all should be well.

I had this same problem. it actually caused me to buy a new processor that I wanted anyway, but I couldn't get the computer to boot off of the WinXP Pro CD. It would always hang at the file that supported multiple processors. I finally fixed the problem by disabling the quick POST in my BIOS. for whatever reason, this solved the problem. maybe that will work for you without disabling the DLL in windows.

Thanks for the help, but the company I bought the processor/motherboard from replaced them both. It works great now! Thanks.

I think mup.sys is getting a bad rap in all of this. I had the problem, where booting in safe mode, the computer would hang, and the last line listed was the mup.sys line. My problem was actually solved by moving a ram chip from one slot to the next adjacent slot. The computer will hang if it gets a bad read from a ram chip, and in this instance, it was hanging coincidentally when the mup.sys line was displayed.

Agreed. I was able to get into the recovery console and successfully disabled mup. (For the record, you just type disable mup, not disable mup.sys.) After doing this, I rebooted in safe mode and now it just hangs in a different spot. I'll keep working on mine and see if I come up with anything. My theory is that my cats knocked something loose and now bootup is hanging. Stupid cats.

Boot into safe mode with command prompt. Get a copy of mup.sys off of another XP machine. Put it onto a floppy and copy into c:\windows\system32\drivers This will take care of it in 5 minutes or less.

I just ran thru the same problem. But mine's worse. When i try to boot up using the win2k setup CDROM it would also hang. Finally i managed to get Windows to startup by removing all my PCI cards, moving my boot drive from my IDE controller to the on board IDE controller, and moving one of my 256 DDR RAM to the next slot. I removed all the hardware listings (under hidden) and reinstalled each PCI one by one. Now it works. Thanks guys for your posts to help me get started. I have been so stressed out and irritated by this MUP.SYS issue.

WIth my previous post, I thought it might be useful to post some background information 
for folks running into the same problem.

I was installing a PCI based professional Digital recording and mixing sound card 
when this happened - M-Audio Delta 1010LT.

I was running my HDDs off a Maxtor ATA133 PCI controller card
GeForce 4 Ti 4200
AMD 2000+
MSI Ultra KT333 mobo
512 MB muskin DDR 333 (2 x 256MB slot 0 and 1 at first. I had to run them at slot 
0 and 2 later to make the 2nd 256MB post)
NEtGear PCI 310 Ethernet
DVDROM and Burner running off onboard IDE (one per channel)

Everything works well now. I am so glad i did not have to do a low level format. 
I retained all my settings and OS.

Thanks again to all the posters here. I was searching MS support site and could not 
find anything useful there with regards to this problem. It is forums like these 
that gave us folks some hope. Thanks a million.

The problem with that Jay is that in my situation, it would not even boot into safe 
mode. It would hang at mup.sys. Even when i try to boot using the CDROM setup disk, 
it would hang as well. I was running out of ideas when i started to move hardware 
around and got it to work after trial and error. I am still very unclear what is 
the real cause of this. MS seems very tight lipped about this as well coz i could 
not find any thing on this issue on the MS support Knowledgebase.

I had this same problem in Windows XP and finally figured out what fixed it in my case. I couldn't boot regularly, safe mode, from the XP CD, etc. I had no way of getting into the system! The USB problems people have mentioned on various message boards prompted me to check my usb mouse out. It's an optical mouse so I could try it in another machine and tell immediately whether it was working (since it lit up). Unplugging it and plugging it in again while the machine was off didn't help. But when I got to the mup.sys line while safe mode was booting I unplugged the USB mouse and the machine continued to boot! I now have the mouse plugged in and it reboots with no problems. So, yet one more thing to try; unplug all of your USB devices after the mup.sys line appears. It may just continue!

I have almost the same problem. After I upgraded my video card to Radeon 9500Pro, my computer randomly halt in games, NWN, C&C Generals. How ever, all other programs run well. The problem is much more serious after I changed my CPU from Duron 1.2G to Athlon XP 2400+. The computer halts all the time. It takes long time to enter windows xp, can not pass 3DMark 03, can not pass disk error check, can not enter safe mode (some time can). I tried almost everything I can, changing RAM, removing cards (NIC, TV card, Video card), changing IDE cables,formating HD, reinstall XP. Problem was still there. After I installed windows 98 on another hard driver, everything was fine. So, it may not hardware problems. I noticed the computer takes long time to load mup.sys, so I decided to have a look about it. Didn't find anything from M$. Thanks goodness, I found this message. Now my computer runs well. It passed 3DMark 03 without any problem and I can copy 10G files from one HD to another. This is what I did after view the message: 1: disable mup. 2: change NIC to #5 slot (my motherboard has five PCI slot and some IRQs are shared). Why #5? because #1, #5 and ACR shared same IRQ and I don't have ACR card and #1 slot is empty.

I tried disabling the mup and it just hung at a later point, so I unplugged all usb devices and chose last known good configuration. This finally got me into windows xp. The first thing I did was go to System restore and go back to the last system checkpoint. After the system restored successfully, I plugged everything back in and it seems to work fine. I think it had a lot more to do with choosing last known good configuration as I had not chosen that before.

Well I am having the same problem right now. I have been posting on MS's newsgroups for the past 2 weeks and they have not posted 1 time to help. I am having the problem where it will not boot even when i enter the cd. It gets to the point that says starting windows but never gives me the option to repair.. it just freezes. I think i am going to try and put the HD in another computer(since it works that way) and disabling Mup.sys. If that doesnt work i am going to try a new processor and see if that works. Great posts guys just wanted to say thanks for posting.

well. tried hooking my new hd up to my old computer. and i got an error "a read error occured" then after trying all jumper settings i set it up as a slave and i can read the hd. no problems. so i decided to change the hd back to the old computer and tried from there again. Removed the USB 1 and 2 support removed audio support tried everything. so i have to wait to the weekend to try and disable the mup and the new processor. any other ideas.. .help

OK - I'm coming in well into this, but i found this thread when i, too, attempted to boot into safe-mode only to discover a 'hang' at the moment after MUP.SYS loaded. But I had some pretty severe symptoms that led me here as well - 1. my floppy couldn't recognize a disk with known-good data - it reported messages saying any disk was 'not formatted', and even then i couldn't even get it to complete a format on a blank fresh floppy. 2. my CDROM could play music but not show me the track.cdda file list in an 'explorer' window and my DVD-ROM couldn't do anything. 3. my networking was inoperative. IPCONFIG wouldn't run at all. 4. event-viewer said the 'null', 'beep', 'ipsec', and a variety of other services had failed to start because the related drivers were 'invalid' 5. my device-manager reported my floppy disk with a yellow exclam point, my 'microcode updated device' (a system device) also with a yellow exclam. 6. i had already tried 'uninstalling' the floppy disk and 'reinstalling' it - with no luck so today i started looking at these drivers (mup.sys, flpydisk.sys, fs_rec.sys, etc. tcpip.sys, and some others) in my Windows/system32/drivers folder. lo and behold, when i ran the mouse over 'em, some of the drivers in the folder clearly gave little balloon messages what they were, while the ones named above only showed the 'date created' and no name or function info in the balloon. i concluded those must the the 'invalid' ones. happily i had a copy of XP drivers from another XP computer I had partly backed up and started locating 'invalid' drivers on the one XP computer and replacing them with copies from the other (good) XP computer. BINGO! within minutes I had my networking back (by replacing the tcpip.sys), then i kept going and now i have my floppy, cdrom, and everything else. btw, refreshing MUP.SYS made the device-manager 'microcode update device' error mark disappear. turns out the floppy really needed fs_rec.sys (filesystem recognizer driver) refreshed, and that also made the CDROM come back. i wound up refreshing null.sys, beep.sys, and a bunch of others and that made the event-viewer stop reporting all those errors on bootup. no more 'invalid drivers' causing various services to not start when needed. i don't suggest doing this willy-nilly. i was careful to match byte-counts and original 'date-created' on each one and only refreshed ones that 'appeared' invalid by the lack of function/name in the balloon indicators. a little tedious, but the computer is back to 100%. i hope this helps you all get to the bottom of this. btw, MUP.SYS is the 'multiple UNC' driver, but it is reflected in your device-manager as 'Microcode UPdate Device' - which makes more sense. not that i know what this thing *does*, but I bet it is the thing that updates WinXP when you add a hard drive or ram to your computer. i haven't tried again to boot into safe mode, but i bet it won't hang after MUP.SYS now :) Good luck, folks - hope you succeed in fixing your systems.

I started having the freeze at mup.sys problem after intalling an audigy LS and then an HP CD burner. I had several successful reboots after the upgrades. Of course the lockup started the first time I rebooted with the case back on. I removed the card and the burner, no luck. The interesting thing is that I could boot into Linux with no problem, but XP would hang every time. ***I swithing the DDR stick to another slot, and voila, it boots again...very odd, but minimally invasive...glad I did not have to do a repair from the CD***. The solution does not make sense to me, but hey it's a Microsodt product (useful yes, dependable no). So thanks everyone for the non-sensical workaround tha really works. If anyone knows why windows would fail but not linux, I'd be interested to know.

I recently had the experience of Win XP hanging during load, with nil on screen, and eventually figured out it was stalling at mup.sys. Tried rebuilding the PC but the Win XP install wouldn't run. Then booted from floppy & re-formatted HDD, still no joy. It was then that I realised that earlier that day I had gone into the ROM BIOS and enabled the Bios antivirus facility. So I disabled it again. Having now rebuilt my PC without incident, I tested this again by re-enabling the BIOS antivirus, and sure enough the PC wouldn't boot. This may not solve anyone else's problem with mup.sys, but thought I'd share it just in case.

I tried going into Win2k Pro repair mode and disabling mup.sys but got a msg saying 'disable' was an invalid command. Any Suggestions?

MUP.sys hangs WindowsXP - solution
Sunday, January 4, 2004 at 6:04 am
Posted by Paul (2 messages posted)

Well - my solution is to change the computer type in Control panel (System- Hardware- Computer)from 'Uniprocessor ACPI' to 'Advanced Configuration and Power Interface'. I think MUP.sys hanging WinXP is a power problem NOT a porblem with MUP.sys. I tried everything that everybody else tried - changing and removing hardware, disabling mup.sys, rebooting again and again, etc etc. All a complete waste of time! The problem seems to be that changing any hardware (eg removing the USB mouse) makes WinXP start and then changing it again makes it stop - and it also seems to be incosisent so it sometimes works and seomtimes doesn't. So I even got to the point of removing a memory module (everything else was off!) and it started working. Any way, I then went into Control panel and applied the changes above and it has worked fine ever since, even when removing or adding hardware. I have now attached all my hardware again and it has worked fine for about 10 reboots. Good luck Paul

My son's computer hung at XP mup.sys as well. Just prior to re-formatting the drive and reloading we noticed comments here re usb and tried unplugging the new USB hard drive storage device. XP then started without a hitch. It seems to be a USB problem and an intermittent one at that. The drive is a 2.0 USB but the computer is 1.1.

I have this problem now too...kind of. Was working on a friends computer. Put in a new PCI SCSI card and CD Burner. Rebboted the computer a few times, everything seemed to work fine. Then. for no reason, the keyboard and mouse stopped responding when mup.sys loaded. Works fine moving around the BIOS. Everything else seems to function properly except the keyboard and mouse. I took out the SCSI card and burner. Still the same. Anyone?!? I'll try everything below, but, I don't know since he has the old PS/2 style keyboard and mouse.

Found this message thread via Google and it saved the day for me. Just thought I'd contribute to the accumulating info/knowledge on this problem. Today Win-XP wouldn't boot into ANY mode - hanging at MUP.SYS as described by others. I unplugged my USB optical mouse (Microsoft mouse by the way) and USB CompactFlash card reader. Win started up fine. I immediately shut it down again, plugged my mouse back in and re-started. All is now well. We'll see if the problem re-appears. Note that in the past 3 weeks I: a) changed from a regular mouse to the USB optical mouse. b) accepted a USB update from the Microsoft Windows Update web site. --jeff r--

I found it. To make this work, I had to install Windows XP to dual boot. Once inside XP, I edited the problem Windows 2000 registry and found that the keyboard and mouse were disabled. I set the registry keys back to "0" and booted Windows 2000. It seemed fine. I have no idea why these keys were set to disable to keyboard and mouse. The only thing I did was reset the Search Preferences in Internet Explorer back to the defaults. Some hack had sent code to my friends PC to set it to some "SearchXLS" site. Hmmm. Here are the keys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Kbdclass\Start HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Mouclass Actually, CurrentControlSet was not there, I did it for ControlSet001 and ControlSet002

Your tip helped in my case as well. I guess the problem is in starting order of the drivers. Same result may have been achieved by setting the start value of mup.sys larger than 1 which seems to be the default value. I did'n test that so it's only a wild guess. Thanks! pasi

I have the similarly described MUP issue. I was at home the other day, and all of the sudden, my PC just reset, like as if it had lost power. Then it came back and got to "windows XP professional" and it has a progress bar, this is a black screen with the XP logo. then, before the windows blue/teal screen comes up, it reboots again as if the Reset button was pressed. now it is doing this constantly. it is in a 'boot loop'. At this point, I decided that this may be some type of hardware failure. I began to remove various HW, down to the point that I have RAM, 1 HDD, and AGP video card. still same result, getting a boot loop. Then I tried disabling everything in the BIOS, onboard NIC, usb ports, etc. still getting a boot loop. then i tried to boot with safe mode. Yesterday i got safe mode to start OK, but i wasn't sure what to do at that point. I then rebooted, and same results. today, I got more extensive. I decided to reload win XP Professional. I reloaded, and am able to get to the setup program and the bootable CD works great. I tried to have setup "repair" windows. It ran itself, then it has the same result after rebooting. boot loop. Now i load the XP cd again, and I can go to recovery console. well, i am not a MCSE on XP or anything, so I didnt know what to do from the recovery console. This is really starting to kill me here. I didnt change ANYhting. I have a spare 12GB known-working HDD. I swap this drive into the machine. then I load XP on the blank HDD it sees the partition, it is NTFS. it loads all of the XP files. reboot, and STILL no luck, getting this same boot loop. now we have clean new SW loaded, and a different HDD and no go. I then tried removing all HW, except AGP card and RAM and HDD. still not working. I then brought the PC to work with me, I am a support rep at a SW company, so I am thinking i can get a good second opinion from a co-worker. they suggested all of the above, go to bare bones system, and start swapping out HW. so I swap all components with known-good parts. swap the video card with a known good card. nope. swap the RAM with known good RAM. Nope. then i tried the above diable MUP. I used the XP recovery console to disable MUP.sys. it disabled itself. still no luck. if i try safe mode, i get to sisagp.sys and hangs there now. if i try last known goodd configuration, then the screen just turns blank and it sits there. if i use safe mode with network or just safe mode, it gets to the sisagp.sys and just hangs. I am at a loss. These posts say that a new processor resolved this issue. that is the only thing that I have not swapped. I cant think of what else would cause this. here is my HW. it is a P4 1.7 256MB pc2100 ddr 12GB western digital HDD. 64MB nvidia gforce III ti200 ps/2 keyboard, and i did have an optical USB mouse. I havent tried to unplug the mouse while it is stuck on the mup.sys error. Please help!!!

re: MUP.sys hangs WindowsXP
Saturday, January 17, 2004 at 9:14 am

I'm also facing the same symptoms of the computer hanging at mup.sys on startup. 
My situation is as follows:

When I connect my disk drives to the secondary IDE controller and leave the primary 
controller empty, the system boots up without a problem.

When I connect my drives to the primary controller, I will hang at the mup.sys line 
unless I boot in safe mode. Booting in safe mode with network hangs as well.

Anyway, the problem does not lie in mup.sys, but rather the stuff that gets loaded 
after that. Mup.sys just happens to be the last driver that's loaded that actually 
displays something on the screen. This can easily be verified by disabling mup.sys 
(as mentioned by many other people) and then the computer will just hang at the line 
before mup.sys.

Looking through the boot logs, I compared booting up in safe mode with and without 
network. For my system, the additional drivers that are loaded are:

\SystemRoot\System32\DRIVERS\el90Xbc5.SYS (3COM network card driver)
\SystemRoot\System32\DRIVERS\rasl2tp.sys
\SystemRoot\System32\DRIVERS\ndistapi.sys
\SystemRoot\System32\DRIVERS\ndiswan.sys
\SystemRoot\System32\DRIVERS\raspppoe.sys
\SystemRoot\System32\DRIVERS\raspptp.sys
\SystemRoot\System32\DRIVERS\msgpc.sys
\SystemRoot\System32\DRIVERS\psched.sys
\SystemRoot\System32\DRIVERS\ptilink.sys
\SystemRoot\System32\DRIVERS\raspti.sys
\SystemRoot\System32\Drivers\NDProxy.SYS
\SystemRoot\System32\DRIVERS\rasacd.sys
\SystemRoot\System32\DRIVERS\ipsec.sys
\SystemRoot\System32\DRIVERS\tcpip.sys
\SystemRoot\System32\DRIVERS\netbt.sys
\SystemRoot\System32\DRIVERS\netbios.sys
\SystemRoot\System32\DRIVERS\rdbss.sys
\SystemRoot\System32\DRIVERS\mrxsmb.sys
\SystemRoot\System32\drivers\afd.sys
\SystemRoot\System32\DRIVERS\ndisuio.sys
\SystemRoot\System32\DRIVERS\srv.sys

I suppose it's one of these drivers that causes the system to hang when booting in 
network mode. The problem is that when the system hangs, it does not save the boot 
log so I have no way of checking where exactly it hangs.

Has anyone seen something simliar to this?

I was having a similar problem in win2000. Keyboard worked fine in BIOS setup, stopped working once win2000 fired up. Couldn't get into safemode, etc. I read an article at MS win2000 tech site. In short, the problem was the driver Iomega Zip software/driver i loaded was too old. The solution given is to go into the Recovery Console and disable IMGATAPI then enable ATAPI SERVICE_BOOT_START. The additional problem in my case is that the Console is not loaded and I don't have the install disks so I can load it/use it (and I don't have floppy recovery disks either). But I thought I'd post this anyway in case it helps someone; the problem for some folks may be an old atapi or USB device driver, etc.

OK.  I *think* I have a final solution to all of this!  1st, the short answer:  reset 
ESCD in your BIOS.  Now for the long answer:

I had the EXACT same problem as Justin below here although my hardware was TOTALLY 
different.  Just as it seems with all the other sufferers of this issue.  After trying 
absolutely everything that was suggested on this thread with no success, I started 
realizing that some of the posters were right:  this problem has nothing to do with 
mup.sys.  It has everything to do with what gets loaded after it; and that seems 
to differ from machine to machine since hardware configs are so vastly different.

ESCD is the part of the BIOS that handles allocating resourcs to Plug n Play devices. 
Sometimes it gets freaked out and needs to be reset.  Some BIOS's do this for you 
if you make a hardware change (remove a card, change memory slots, move USB device 
locations, etc)  Thats why there have been x number of different fixes for this problem. 
I remember seeing "Updated ESCD Successfully" on other motherboards I've owned in 
the past, even though I never told it to do so.  I've also noticed that adding hardware 
causes the ESCD to freak out somtimes requiring a reset; although I added no hardware 
to cause it to happen to me.  I just put some thermal grease on my processor/heatsink. 

Here is a link describing ESCD:  http://www.pcguide.com/ref/mbsys/res/pnpESCD-c.html

I hope this helps shed some light on this very frustrating problem.

OK, I've had the same problem with XP freeze and Safe Mode stall at Mups.sys. Final solution was to re-flash the BIOS (downloaded the file from another computer). It seems to me that Mups.sys is just the last file shown before XP goes graphic mode. It did the same pause once I resolved the problem. It may be at this point that it does the hardware "head count" to match its security settings aginst the activation code. Reading through other forums, it appears that XP is highly sensitive to hardware instability. In my case, the capacitors on the m/board are swollen which may have lead to damaged ROM. Apparently, some m/boards reset the BIOS ROM on ESCD; so occasionally a hardware change fixes the problem and sometimes it doesn't (like my Epox). It became obvious that it was a hardware glitch when Win98 on my second hard drive started to freeze as well. Because of previous fiddling (made the mistake of deleting "viaagp.sys", so lost graphics) I had to do a complete re-install of XP on the main HD; and now she hums along better than before. Next freeze and the M/board gets ditched - it's about 3 or 4 years old.

I just spent 2 hours working on a friends XP box, trying to fix the problem aforementioned. Before I reveal the "fix" that I stumbled on to, I have to say that this forum thread was completely useless except to let me know I wasn't the only one experiencing a mup.sys lockup. Almost everyone here used a different technique to fix the problem, which tells me that no one here really knows what went wrong. I find this frustrating. The fix for my friend’s computer was to select “optimized default” in the BIOS root menu (many of you may not even have this setting), then reboot, and then select “Fail safe default” in the BIOS root menu. Don’t ask me why this worked, but it did. My friend was happy, but I walked away without learning anything! I just have this feeling that we’re missing something.

I don't know if anyone of you had just installed Daemon Tools but that is what I had installed and then I ran into this lovely mup.sys lockup. When I would run XP in safemode I saw that after mup.sys loaded I was given the option of letting d344bus.sys install or escaping past it. The only way I could get into safe mode was to use the escape key to bypass that install, and then I could get in. So I went into the recovery console and disabled d344bus.sys and I was once again able to run Windows normally. Well, almost normally because now I have no USB support at all. Doesn't detect any of my devices, so I need to figure out how to reinstall those. But I was able to get past mup.sys!!!! So, if any of you have recently installed daemon tools this might be your problem. (this is Daemon Tools 3.44)

updating my own problem: As someone had suggested earlier I had set my bios back to defaults, which disabled my USB support. I turned that back on, and now have USB again. So, basically, Daemon Tools was the problem which was making Mup.sys 'stall'. So, I'd check any recently installed programs that have something installing right after mup.sys and remove those.

I am having a similar problem to you all. One day the computer just hung and then whenever I restarted, it never got past the MUP.sys file. There was no way to get past it and through to windows. In frustration I formatted the computer and reinstalled Windows on the hard drive, by putting it in another computer. Well it installed ok, but when it came to put it back in my computer, it did the same thing. After some messing around in BIOS, I managed to get it past MUP.sys but now its stuck on the next file, AMDAGP.sys in exactly the same way. I have tried unplugging everything etc. but to no avail. I can't understand whats going on. Any suggestions?

How I fixed my computer...
Friday, January 30, 2004 at 4:30 pm
Posted by Martin (1 messages posted)

Same problem...  this is how I fixed my computer. 
(AMD XP 2700+, EP-RDA3+, ATI 9700pro)

How the problem appeard: 
Installed XPP, SP1a *boot* nForce 3.1 Drivers, dx9b *boot* ATI Catalyst drivers *boot*
And at last Nero6.3. Enabled ImageDrive and booted.

The system rebooted and the last thing loaded was mup.sys. Disabled it. But the system 
failed on the next driver instead.


So i disabled some Nero files. "imagesrv" and "imagesys" and XP started up niceley.

The "Safe Mode" option is still loading drivers installed after the "clean" XP-install. 
 

Since everyone is experiencing the same thing, but the the "path" to the problem 
is almost always different I think we can divide the problem it into crappy hardware, 
crappy drivers and crappy config.

If the computer just crashes and this appears and you are absoluteley shure that 
u havnt installed any new hw and apps , check hardware (especially when the harddrive 
is clicking)

If you tweak the BIOS or disable, say ACPI, and the computer hangs... just load default 
or optimizesdefaults.

If you install a app and the this problem appears, find out what drivers are loaded 
and disable them with Emergency Repair on the XP install CD.

Maybe some pretty obvious points but anyways.. 

So long fellas!

/Martin

I joined the Muppets.sys club today, with a failed boot of winXP. Just like others user's I am unable to get past the boot screen, with or without the XP CD. I run a PCchips m810 v7 Mobo/AMD XP 1600, 256ram, NVidia Ti (64mb), Terratec DMX6fire sound. The only USB device connected to the PC at boot is my DSL modem. I cannot see a common fix in the current posts, but will try a few things and report back.

This sounds like the answer closest to the real problem after having read *all* posts.
Something seems to be screwed up and after kicking it hard enough (maybe that's resetting 
ESCD) it works again and will never happen again. NONE of those who said that they 
fixed the problem (no matter which way) later posted again that the problem re-occured.
So I'm pretty much convinced (and truly hope!) this is a one-time problem.

Actually, my problem came back again. I tried resetting ESCD to no avail. I thought that it might have something to do with how the motherboard set the voltage level for the processor. I have an 1800+ and it used to run at 1.5v. The supossedly bad board ran it at like 1.8v so I thought that might be it. Since I couldnt adjust the voltage, I decided to go to a local parts store and try a motherboard in their service area. That seemed to fix the problem even though the new board had the voltage at 2.0v! I returned the supposedly bad board and got my money back. I havent had any problems since. So the strange problem really still seems to exist at least in some capacity.

People, don't you realise that the driver which loads after mup.sys creates this issue? And that would be - the AGP VGA card in most cases. Either you have a cheapo AGP card, probably on-board with damaged controller or anything in that sense... or ... I'm totally wrong :-) MM

Ok, I'm getting desperate here and any help I could get I would be extremely grateful 
for.  I've tried to include as much information as possible.

Last night WinXP was running very slow and locking up, which isn't too unusual as 
I had a thumbnailed window with some large vid files open and a few other programs 
running.  I probably hadn't rebooted in a day or so either.  I tried to restart but 
it just kept locking up so I manually powered down, waited a few seconds, and powered 
it back up.  As I recall, the last message that flashed on the screen was that my 
cordless mouse was low on batteries.  On rebooting the black WinXP logo loaded, stayed 
up for an unusually long time, and then restarted.  This time the "Windows failed 
loading on a previous attempt" blah-blah screen came up.  Have tried load normally, 
last known good config, and safe mode.  All just loop back into a reboot.  Safe mode 
loading stops with mup.sys before rebooting.  I have an OEM Windows XP so I haven't 
been able to use the Windows console to try and repair anything.  I originally thought 
it might be a problem with the master boot record, but that seems to check out ok 
as far as I can tell.

Today I have tried switching the RAM into a new slot, changing BIOS settings, removing 
my AGP card, and replacing my cordless mouse and keyboard with corded PS2 ones (all 
from suggestions I've read on here).  Nothing has worked.  I'm assuming it's a problem 
with the driver after mup.sys, but I don't know what that is and even if I did how 
to repair it or bypass it without the Windows console.  I have a suspicion that it's 
something to do with my AGP card because I have been having a very odd problem the 
past 5 months or so (and I bought my AGP card, a Raedon 9200, about 8 months ago) 
which involves the monitor apparently losing it's signal suddenly and without warning. 
 It only seems to happen when I'm actively using AOL Instant Messager (but I can't 
say for sure) and I think audio output stops at the same time (but again, I can't 
say that for sure).  Tried updating the vidcard drivers a while back but that didn't 
seem to stop the problem.  The only way I get around the problem is to manually turn 
off the power and turn it back on.

The only other odd thing that happened is that last night right after the mup.sys 
problem started, I turned off the computer power and was going to call it a night 
and about 20 seconds later, the computer turned on by itself.  I've never had that 
happen before and I don't even think it has that capability.  Problem with the power 
supply?

I'm running this system:

AMD Athlon XP processor 2000+ (1.67 GHz)
VIA KM 266
80 GB HDD
512 MB DDR (PC 2100)
AC '97 Audio
S3 ProSavage8 (integrated) [Radeon 9200 in AGP slot]

I've added the Raeon card, a cordless keyboard and optical mouse (using the PS2 ports), 
and a printer/scanner since I've had the computer.

This is extremely frustrating and I need advice!

I also joined the muppets.sys club today. I could give a detailed account of my woes but i will only give what is different: my problems started after trying to install a combo 2.0 usb / firewire card. upon installation, win xp home just blanked. i then went into this whirlwind of hell that everyone else has described. i also dont think it is mup.sys, but some other driver that installed itself during my card installation. i have tried to reset the escd, etc. etc, in bios to no avail. however, i AM able to get into safe mode. the last file safe mode lists is mup.sys, but it goes into it just fine. i am not sure what else to try, having done the bios things as others have suggested. i will let you know if anything works.

I see that this is a major headache for more than myself. I too have the mup.sys hang, will not boot from floppy (hangs) or CD. Tried safe mode but hangs at the mup.sys file. Windows XP hangs after about six passes of the progress bar. Eventually booted once using last successsful startup option but on shutdown and restart same problem. Tried changing BIOS settings, swapped the RAM modules, disconnected the hard disc, one of the CD drives but nothing works!! If I could get into DOS I would reformat the hard drive. Why is thsi such a problem?

Just to add a little bit to what I said before, I can boot from a CD or floppy but as I only have my OEM CDs my only option is to reinstall WinXP wiping out everything I have on my HD, which, if at all possible, I would like to avoid. I'm considering buying a new HD, installing WinXP onto that and making my old HD a slave, but I don't want to do that if I'll still have problems booting. Suggestions?

My computer died on Wednesday - I'm booting from twin 120gig RAIDed (0) SATA drives, and now does the normal get to mup.sys and reboot again.. Thing is, I found an old IDE drive, plugged it in and did a fresh install of XP, and it booted fine! Does this mean (please say it doesn't) that it's my RAID gone belly up? Don't entirely understand how that could be so, as it does start to boot off them - just doesn't get past mup.sys so they can't be entirely screwed.. Tried flashing the bios, moving/removing various bits (but since it boots fine on the IDE drive, I'm guessing that hardware isn't the problem).. Anyone got a clue how I can get into my RAID drives? Nothing amazingly important, but I'd still prefer not to lose them.. The IDE install of XP doesn't see them...

I have the exact same problem. My configuration is: AMD 2000+, GigaByte 7VAXP, Corsair 3200XMS, ATI Radeon 8500 128MB, WDC 40Gig HD, MDT 120Gig HD, Win 2000, MFC 7300C printer/scanner/fax, Logitech Elite Cordless Combo. Seems this problem happens to both win2000 and winXP. I've too have tried all solutions suggested here and nothing works. I can't even use a boot CD or floppy. I've stripped everything down to essentials, tried corded keyboard and mouse, switched cards, mem and cables around, disabled/enabled bios attributes, flashed upgraded bios everything I could think of except for replacing hardware. If it is a Hardware failure I haven't a clue what it could be. Any suggestions on how to proceed?

ok here is something strange. about 2 days ago, my roomate's computer stops working for no reason, and after some fiddling around we figure out that it is the dreaded mup.sys problem. our computers are networked. just today, i am in the middle of running windows and for no reason it just locks up. sure enough i reboot and it just keeps rebooting itself....now my computer has the mup.sys problem! what are the chances that both of our computers, each with very different specs and hardware, would get this problem within 2 days of each other after never having had a problem for 12+ months? neither of us recently added any hardware or software, except for partypoker.com, but i hardly think that would have anything to do with it. also, i have 2 partitions on one hd on my comp, each partition has xp pro. the first partition has the mup problem, the second partition works just fine. what the hell is with this problem? after reading all the posts, it appears everyone has a different solution.... pretty crazy.

I changed my CD drive and can now boot from CD but it still hangs when trying to boot up/install from CD. Also hangs when attempting to boot from a Win98 start up floppy. I am taking the problem to a terchnician as I do not know whether the problem is hardware or software. The discussion groups don't seem to throw up one definitive answer.

I think it’s definitely bios to OS config problem. I was able to install Win98 on an old 1GB drive without any problems except that it’s not compatible with NFTS, so my other drives are still inaccessible. After in Win98 I tried to upgrade to Win2000 but it still hangs on the reboot. Then again maybe it is a hardware failure that just affects newer OS's. Can't figure this out.

I have a USB 2.0 multi-card reader on my system. when I placed two different USB devices into the reader or empty USB port, and rebooted, I got the blue screen, and mup.sys hang. I fixed the problem by unpluging the cardreader from the motherboard, rebooting, shutdown and reconnect the reader. It is working okay now.

I too came in search of MUP.sys problems.. i had an odd situation. I installed some used memory and i got an error saying to load the DLL's for the kernel... so i was like "man, that's lame" so i switched the memory around, and got a different error. could not load windows (i forgot the reason) so then i took all the memory out, and put my 1 stick back into slot 1, and it started, but gave me the mup.sys routine. so i came her via google and tried all the problems... the switching the memory around had already been done, but i tried again.. no luck.. disabled mup, no luck, unplugged USB devices, no luck, took out pci cards, no luck.... finaly reset bios defaults... worked fine.. i then realized that i had changed the bios settings earlier (to boot from cd first)... and didnt change it back. "Go team BIOS!"

I have the same problem that you all have. Mup.sys is the last thing I see when trying to go to safe mode. I got my XP to launch when I removed my ½ year old 120GB Hard Drive. When I got back to XP I had to reinstall graphic drivers. If I try to put my 120 HD back to my PC it hangs again and if I start XP in normal mode the last thing to see is the "Windows is now starting up..." and thats all. Has anyone solved how to get the device that hangs your XP to work?

I thought that I'll give you some more info. I have logitech wireless keyboard and mouse but I think It's not the problem. 1 day before this "mup.sys hang up" happened I had some problems with playing video and music files. They were running slow and "stuttering". At the same time my Logitech keyboard started to bug. My quick buttons were not working properly. They didn't perform the actions they were supposed to perform. The hang up happened when I yesterday clicked "yes" to microsoft auto update. After the update was ready it wanted to restart and after that it hung up. After the hang up and removal of my 120GB HD all these problems were solved. But now my 120GB HD doesn't work. It should be physicly fine 'cause I use diagnostic tools etc. So, with these additional infos I hope theres someone with same kind of problem and HAS SOLVED it. I want my secondary HD back to life!!!

Well if that's so then why my XP loads perfectly when I remove my 120GB Hard Drive??? I have also suspected that it might be a graphic card or driver problem (cause when I took my secondary HD away from my PC and XP loaded, I had to reinstall graphic drivers) but this doesn't explain why my XP loads when my other HD is not connected....

I'm quessing that it's a driver issue... I'm in a same situation right now. My secondary 120GB HD doesn't work. If it's connected to my PC, XP will hang up to "windows is starting up..." screen and in safe mode to mup.sys --> but I think it hangs to the next .sys comming up. If I can somehow overcome this problem I will let you know.

Mine was working fine for 3 months too, I'm guessing that tolerances change as time goes by, perhaps an update makes some bit of hardware consume slightly more power, and it just reaches it's limit and stops working.. Of course this could all be total rubbish.. I'll find out when I get my new bits tomorrow..

I just made a little test... As I have said my system will boot to the "windows is starting up..." screen and crash when my other HD is connected. Well I conneted the hard drive again and waited till the starting up... screen and then unplugged the HD on-the-fly... Windows said following --> "unable to save data from e:\. Please check your device or network settings" I clicked ok and XP loaded fine. So the lock up occures while XP is trying to save something from the HD and then crashes. I tried this again with safe mode and got the same mup.sys lock up and by unpluggin the HD it started just fine... Well I don't know if it's my HD that's broken or what but this is what I discovered...

so i just joined your crew of people stuck with Mup.sys. All i did was upgrade my cpu from an AMD xp2100 to an xp2400 and boom! no more booting into xp pro. It looks like no one can figure out this mystery as I read the entire thread above and every person has a different answer (which i tried without any success). Can someone post when they solve an issue or if you have any new tips? Much appreciated!

Let's try to see if there is some correclation here... I have the same mpu.sys issue and my only hard drive in the system is a 120G Western Digital. Is yours a WD also? maybe the problem is with the hard drive? My XP boot CD can't even get to the install screen it also hangs at starting windows after loading all the drivers. thanks.

I finally figured it out and yes, i can't prove this is the fix for everyone until you try it yourselves. It looks like the power supply has something to do with this. As soon as I moved this hard drive from a 300 W power supply case to a 400 W case then it booted fine. I tried all the other suggestions from the other threads here without success. Why it was working before, I have no idea. Hope this helps someone. later!

I have also just joined this problem.

At first it all started when my friend has winME (Yes i know, big mistake) and it 
started crashing out all the time.  We decided it was time for a fresh reformat on 
the 40gb HDD.  Wiped the whole lot and lone behold it wouldnt format in WinXP installer 
(from DOS).  It got to 99% and it would say... 'Hard Drive Possibly Damaged.'  I 
knew this wasnt right, so i took it to work with me and set it off on a 7 hour HDD 
fitness test... the results, perfect!!

So then i started to install winXP pro with SP1 and RU1 on the hard drive and it 
went on no problem, i rebooted about 8 times doing so and each time was faultless.

Now i've brought it back in thinking it would work no problem and now i get this 
mup.sys.  I'm going to try another reformat on the drive and i will tell you how 
i'm getting on with it later on.  Hopefully it wont take too long :-(

last week my xp1800 went down due to the mup.sys error, I was running win2k at the time, my IT friends considered it a partition failure and we rebuilt the machine using XP. Yesterday it fell over again with mup.sys hanging, I tried a new MB,new videocard, different ram, updated bios, plugged,unplugged everything... still mup.sys hang reboot. I put the orginal MB back in with everything as it was and then increased the Core voltage from 1.74 to 1.85 and it is running stable. There was nothing above that matched what I did, but I can only offer how I fixed my problem, I have 4 usb ports sucking power so I figure thats what was dropping the core voltage, causing the mup.sys to become unstable.

Sorry to hear that. While I was trying my stuff, a friend of mine did some research and gave me this info about mup.sys. I hope it will help you: Applications Use the MUP or the WNet API for Network Access (103925) SUMMARY A Multiple UNC (uniform naming convention) Provider (MUP) is a network resource locator that runs in kernel-mode memory in Windows NT. The types of resources it locates are based on UNC. Applications use either UNC names or the WNet API to access resources on the network. UNC names are a method of identifying share names on a network. A typical UNC name begins with two backslashes followed by a server name: \\server\share\subdirectory\filename WNet is a part of the Win32 API set that allows applications running on Windows NT workstations to connect to multiple networks, browse resources, and transfer data between computers on other networks. File Manager is an example of how the WNet functionality is implemented to provide network browsing and connections to other computers. The MUP is a program unlike TDI and NDIS boundary layers. The MUP receives commands containing UNC names from applications and sends the name to each registered UNC provider, LAN Manager workstation, and any others that are installed. When a provider identifies a UNC name as it's own, the MUP automatically redirects future instances of that name to that provider. Registry information about the MUP is in the following path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Mu "Windows Could Not Start Because the Following File Is Missing or Corrupt: Isapnp.sys" Error Message at Startup (315311) SYMPTOMSWhen you try to start Microsoft Windows 2000 or Windows XP, you may receive one of the following error messages, depending on your operating system.

DING DING DING!!!

absolutely right my man.  For fear of coming off as though i have an authoritative 
knowledge on the subject, i'll disclaim, i probably do not.  However, i am somewhat 
of a seasoned vet to these types of winxp errors. (believe me, i only wish i was 
not) 

I'm actually in the process of reinstalling XP on my trouble machine (mup.sys being 
the main problem among hundreds of others)  and i finally seem to have cracked the 
code on this one.   I had abandoned the revival, after weeks of frustration with 
it.  But due to my internet computer failing, and the one i'm currently on being 
a loaner laptop, i'm determined to get this thing going.   It's an  AMD thunderbird 
1.1ghz   from like 2000 or 1999.  IT was a hell hole since day one, and oddly 
enough, the most stable it's been was sporting win ME,  back in 2000! HAH.

ok anyway, my point of reitteration is DRAWING POWER TO THE COMPONENTS.    

we all know this is a hardware issue right?  Well, if you get right down to the logic 
of hardware, there's only a few things that can actually make a tested and Q.C'd. 
peice of computer electronics fail.  and that's either mechanical failure, overheating 
to extremes, or intermittent power issues.  I suppose there are a few other exceptions 
but those are the big 'uns.  

So you can probably guess that a computer that's been working fine for 19 months 
or whatever, isn't having an overheating issue.  And since the only moving parts 
are the fans and the harddrives, and the harddrives are pretty much the last thing 
to blame in this particular issue, you know it's not them.  Plus like others have 
said, they knew the harddrives were good.

So what really needs to be looked at, is the amount of power everything in your system 
is getting and how the power is getting there.  Unfortunately, we'd like to think 
this kind of electrical engineering background would be completely unneccessary to 
operate and troubleshoot home user computers...but there's no way around the backbone 
of the matter.  Everything needs a certain amount of power to function properly, 
too little or too much and things start to behave eratically!  makes sense, no?

This is why overclockers and cpu/ram geeks have messageboards dedicated to plugging 
in the correct amount of draw ratios and levels for their overclocking thirsts.  
And it's why even reviewers of said rams and processors always say something like 
"now, we DID experience strange issues when we tried to run it at 5:4 with blah blah 
bus speeds etc"

That's raw electrical malfunction in place.  it's not PROGRAMMED to act that way 
with certain settings selected in in the bios.

Ok, i'll end that rant, i think you see where i'm going, E.E. people, back me up 
or shut me down, can't see the failure in that logic though.

What finally seemed to fix my occurance of mup.sys hanging (for lack of a more technically 
correct name for the  phenomenon, since it's not mup's fault at all)  was remembering 
that i had messed with the RAM settings in a desperate attempt to get something to 
trigger action.  I had shut off  paging mode for instance and another key operating 
change i'm not sure of (though it shouldn't matter because it's not like having them 
on or off is a default good or bad thing. it's all relative to what your mobo and 
specific ram NEED)   IN ADDITION
       i had pumped my cpu clock speed way way down in case it was an overheating 
issue or just a "moving too fast for it's own good" issue.  Which MOST CERTAINLY 
DOES OCCUR.

so i pumped the bus speed back up and enabled all the average options for ram (without 
selecting default or optimum, because my bios version of default and optimum does 
more bad than good.  

However, that's exactly why those of you who said "i selected optimum or default 
bios settings and it started right up"  had success.  You reenabled or disabled the 
options of your internal mobo components that draw away or reject all that power 
that is being fed to it.  And it's also why the guy who updated his psu had luck. 
 Ofcourse you need to send these amd systems a ton of juice.  they're overclocking 
systems.  

By the way, has anyone noticed yet that almost EVERY SYSTEM listed here with this 
problem is an AMD???  i'm not shit-slinging amd's.  i'm not sure i personally trust 
them for this reason, but at the same time, its a relative issue.   

it's just that these boards are crazy about power and power distribution.  Both the 
XPs as well as my thunderbird series whatever the chipset is.   They are known for 
tweaking out the most when being messed around with in overclocking arenas.  still, 
the XPs are designed TO BE overclocked.  

and that's what supports my hunch that it's actually BETTER for the stability of 
the system to draw a decent to hefty amount of power to your memory and your processor. 
 It wants to see that power and when it's not getting it, i dunno, maybe the capacitors 
chosen are of a finicky higher voltage and so they only operate correctly on high, 
i dunno, but something doesn't quite sit right until you're really eating up power 
across the board.

this is just what i have found in my experience but also in what seems to be the 
biggest causes for other users experience in all kinds of messageboard topics.   

don't get me wrong. i'm not saying "go into your bios and crank the amps to 11 !!" 
 i'm saying, make sure you check what patrick here checked.  Make sure you're using 
a decent amount of power as a first solution attempt.  But also, check out the ram 
settings.  maybe your ram isn't supporting the bios options.  i know mine only supports 
8/10 ms latency (my bios is spotty so that's the only actual numeric option i have 
besides turbo etc)

you can usually tell if it's not supporting it, if it freezes right in bios or if 
your video won't initialize at all causing you to have to reset the bios.  Same ofcourse 
goes with overclocking the bus speeds.

It wasn't causing "mup.sys" to be unstable though, it was causing the rest of your 
hardware to be unstable and so when XP starts initializing (you know that's what's 
really happening at that stage of boot, right?) all this extra hardware,  it gets 
bummed out by SOME kind of intermittent reaction and it's intermittent because of 
the power distribution.  

Only one other thing to mention,  i also changed my agp card to a shitty old PCI 
card because i all ready know my agp bus in this system to be REAL troublesome.  
AND AGP cards are notorious for causing blue screens (especcially ATI, which lucky 
for me is all the agp cards i have around, and you can forget about me getting my 
radeon 8500 to work on this crapbox.  that card brings enough solid systems to their 
knees as it is. )

So why do agp cards kill so many systems?  well because of the inherent design of 
the M.O. of AGP busses.  That's why there are 3 different genres of AGP: 1.5 volt. 
3.5 volt and 5 volt.  Most require a card that only adheres to its' own voltage or 
else it won't even run it.  This is probably a good thing for stability, but a horrible 
thing for unsuspecting consumers who assume an AGP is an AGP.  

You see the difference betwix the three. voltage.  current.  power consumption.  
and it's all tied directly to the system bus rails.  That's why it performs so well. 
 It doesn't have to be bogged down by the rest of the pci slots sagging the power 
as each device grabs a'hold an electrical teet to teeth from.

black & white:  before doing anything crazy, check your clock speed settings and 
the paging settings and everything that goes along with it.  read up on them if you're 
unsure.  

and then if power changes don't work, swap your video card to a PCI slot card.  

I know it sucks, but at least you'll know what's going on and can either try a different 
agp card (steering clear of ati, just for bad voodoo sake) or aquire a high quality 
pci card if it doesn't cramp your style too much.

ALSO, before swapping video cards, try adjusting the AGP settings in the advanced 
bios settings.  Things like multiplier factor are all just meddling with the power 
flow!

ok sorry if that was too long winded, but i felt i had to reitterate that this is 
not a driver issue or a simple "microsoft sucks" issue.. though i'm not opponent 
to the microsoft sucks school of thought. ;-)

good luck

Fisu, sorry about the formatting problem from my previous message... the sad story is that I thought the PS did the trick, alas the same problem started again for some reason... i almost went nuts with this motherboard (it's a new one)... anyway, I fixed it again by luck... In the bios, I disabled the APIC mode. it listed a line under this APIC called: MPS version Control for OS [1.4]. This was also disabled automatically when i disabled hte APIC mode, and that allowed the system to boot. After I rebooted fine, I went back to the Bios and enabled this APIC mode and everything is still booting fine. I'm not sure what caused the hicup but now I know how to fix it. Hope this helps you. Take care! Jerry.

Ok, not sure if this will fix everybody's problem with system hang during boot, but 
I was just able to get my system to boot ok, and I have been having this problem 
for 4 months now.

I read a reply somewhere on here, in this mup.sys section, and the guy started talking 
about his power supply.

I have also noticed alot of poeple talking about USB 2 card added, and USB hardware.

So, I tried booting up will all my USB devices either unplugged or turned off.  I 
have a USB Scanner, USB Printer, USB 6-1 card reader, USB Camera Connector, etc..

After turning off or unplugging them all, my XP Pro ADM system booted up just fine. 
 So, I tend to agree with the guy that this may be a power problem for many of us. 
 I have a 300W powersupply, but I guess it's not enough to power all my USB devices.

I didn't have this problem, untill after I added my USB Printer.

You should atleast attempt to test your system by unplugging/turning off all your 
USB devices that you can, before you start reformatting and yanking cards out.  It 
may just fix your problem.

I guess I will just keep my scanner OFF so I can reboot anytime.

I just turn on my printer, card reader, etc, after I have successfully booted.

Have a nice day and I hope that this fixes the problem for atleast some of you.

Has anyone had their system hang when booting into safe mode for a few minutes until finally you get the XP loading screen. Once finishing booting it IS NOT in safe mode and mouse and keyboard both do not work. In fact the cursor does not exist. A few weeks ago I had a problem where when booting and got to MUP.sys the computer just rebooted over and over. I am really hating MUP.sys right now. Please let me know if anyone has had this problem and has a resolution to it.

Dan, I agree with you.  From my experience with this sudden Reboot Cycle and mup.sys 
hang, the only way I could fix it was to start unplugging my USB devices.

It worked for a while, then it started hanging and rebooting again.  So, I completely 
unplugged all my USB devices from the back of my USB 2.0 PCI card.  Now it works 
again.

I think I will just have to yank this new USB 2.0 card.  And yes, I do have an AMD 
Athlon 1.0Gh.

I bet the majority of people having this problem use AMD, and have several USB Devices 
such as Scanners, Printers, Mouse Keyboard, Card Readers, etc...  And maybe even 
added a USB 2.0 PCI card to their system.  If so, yank it out!  And buy a 1.0 hub 
and add it to your current internal USB ports.

Been through it all. Swapping RAM finally got me going. However, I also had a ntfs.sys fault which was sorted by replacing it from the XP disc, on researching that, I noticed on other forums that a common factor seems to be Maxtor drives??? I ran their check over mine and it produced an error code so I'm going to replace it under warranty. Could this be the root of all problems?

I ran into this problem today with the MUP.SYS file. You have to boot from the XP cd, then go into the recovery and at the prompt type: disable mup (do not put the .sys) My fix was to go into the BIOS and turn hyperthreading back on, not sure how it got turned off to start with...after I rebooted it still hung and about 10 minutes later booted in fine.....

Hi there

A friend of mine also had this with a HE XP system and after checking initially the 
USB, with no negative results - I removed the hard drive and placed it as a secondary 
master in another system. Immediately, it went through 3 stages of checks including 
NT scandisk and found many errors, which were all corrected.

Once finished, the drive was refitted to the original PC and it booted up fine. I 
then installed Ad Aware spyware checker and it it found 597 nasties !!!!

Once rebooted all was again FINE

Again the result of too much P2P downloading !!!!

Hope this posting helps someone else

Same with me. Suddenly my wife's PC wouldn't connect to my network. Started troubleshooting that issue and ended up with the MUP.SYS problem. I have moved/unplugged/replugged everything to no avail. The only USB connection I have is the keyboard. I've switched it to 3 different USB ports with no success. I've unplugged the PS-2 mouse, disabled the CD-ROM drive, taken out one bank of memory, switched the remaining memory to a different slot, removed the modem card, network card and IEEE 1394 card. My fear is something has gone bad with the drive or mother board. I will keep trying. Next up is to pull the main drive and install in into my PC and run diagnostics on it. If successful, I'll post it.

re: Mup.sys? Only Happens When Printer Is Installed
Thursday, February 19, 2004 at 10:25 pm
Posted by Brian J (4 messages posted)

ok, here is what I know.

I started having the reboot problem, just after I installed my new HP printer.  I 
installed the software and drivers for a HP PhotoSmart 1315 inkjet printer.  I never 
had any problems before, but after I rebooted the first time after installing the 
printer, the reboot problems started.

After installing the printer's software and drivers, my XP Pro AMD sytem would just 
reboot at any random time.  Mostly just after entering my login password.  But, if 
I didn't login, it would still reboot while displaying the login screen.

If I choose safe mode, it would hang, and display the mup.sys line.

So, I immediately uninstalled the printer software and drivers, after I finally got 
the system to boot.  (used last known configuration).

Once I removed the printer from my system, I did not get the boot up errors.

I have tried testing this, over and over again.  I have installed this printer 20 
different times, and each time, it just reboots by itself once the software and drivers 
are installed.

I have tried to use the USB, USB 2.0 Card, and the Parallel connection type, but 
same result.

I find it weird that the problem only occurs when I have the printer drivers installed.

I have, however, installed this printer as a "Generic - TEXT" printer, and it works 
with just plain text, such as from printing from NotePad.  And it does not get any 
errors.

So, I am thinking my problem is printer driver related.  Because I can boot with 
the printer plugged in.  I just can't boot when I have the printer installed with 
the HP software and drivers.

Basically, I have a new HP printer that I can't hook up.

I have another new $99 HP printer, but I have yet to install it.  I will try installing 
it and let you guys know the results.

mup.sys : Tell us about your system
Thursday, February 19, 2004 at 10:54 pm
Posted by Brian J (4 messages posted)

In order to help solve this problem, which seems to be impossible, I think we need 
to start looking at peoples system configuration.

If you are having a problem with your system rebooting and then safe mode hangs on 
the mup.sys line, please reply to this message and leave your system specs:

Mine are:

AMD Athlon 1.0
Windows XP Pro (no service packs)
Generic Ram (256mb & 128mb in two slots)
Generic AGP Invidia 4x 64mb video
1 IBM harddrive
1 Generic CD/DVD drive
1 Iomega CDRW drive
1 Iomega 100 internal zip drive
1 Generic floppy drive
Hercules Game Theatre (external) PCI Card with USB Hub
1 USB MicroTek Scanner
1 HP PhotoSmart 1315 USB Printer
300W Power Supply

AS I stated before, I only have this problem after I install the HP Printer Software 
and Drivers for my printer.  If removed, problem goes away.

If we start seeing a pattern, maybe we can pinpont the problem.

i ran in the same problem, system hang on startup, stopping on the mup.sys line in 
safe mode. Here is my xperience:
1. repairing from cd didnt work as it never went to recovery console
2. removing usb devices dint help
3. removing a 200 GB HDD worked. it started booting
4. moved the 200 GB HDD to a different IDE channel, it hanged.

outcome for my system: a maxtor 200 GB HDD was causing the problem. i have 2 maxtor 
120 GB HDDs and one 200 GB. It was working fine till today, when after a normal shutdown 
it didnt bootup. If i remove the 200 GB HDD from the system it works fine, putting 
it back in any combination of IDE channel selection brings back the problem. Now 
all i have to do is put the 200 GB HDD in another system and see if its really bad 
or what. this 200 GB HDD just had data files (no op sys file).
system specs: windows XP, intel 2.4 G P4, 512 MB DDR ram, 120+120+200 GB HDD, DVDROM, 
DVDRW (on a maxtor IDE controller card in a PCI slot), tv tuner card, IEEE port card.

hope this helps someone.

I'm having tis probleme too, but i think mine is a bit more seveer. I've tryed booting 
with windows cd that's based on winNT technologie and they all hand at the setup 
is starting windows part. I then tryed to install other types of OS ie. winME.. had 
no hang what so ever did all the updates and everything was running fine. Then I 
tryed doing an upgrade installation with no succes, then i had one of my freinds 
come over with his computer and swaped my harddrive in his to install windows XP, 
did have any problemes. Again I did all the updates and then swaped it back into 
my system, still hanged. After that I swaped the video card for his and ram and disconnected 
everythin but the hard drive and in the bios i disabled enything that wasn't needed 
to boot and it still didn't work. I've read every post and tried all of the solutions 
that were posted and they didn't help at all. 

I dont have any USB device but my mouse. here's my system's specs:

Athlon XP 1800+
asus A7N8X-E Delux
256MB samsung ddr333
256MB samsung ddr333
512MB samsung ddr333
maxtor 120GB sata drive
maxtor 60GB ata133 drive
Radeon 9500pro
LG dvd drive
LG burner
sony 3 1/2 floppy drive
Enermax 431W psu

It's not a hardware probleme since it wroks fine in winME. I tried ot install win2000, 
win2000 server, winXP pro, winXP pro french and win2003 server with no luck. I flashed 
my bios with evey existing version of my bios and it still hangs. I tried booting 
with no hard drive with the cd's only, got the same results. Any responce would be 
a big help, thanks

I fixed my mup.sys problem back on friday 13th and my system is still extremely stable. I also have a amd system and STILL beleive the issue is the amount of power your systems bios is sending at core voltage.. with everyone drawing power via usb/video these days the bios default settings isn't enough.I upped mine in small increments and now it is happily pushing a usb Webcam/mouse/Steering wheel/voice commander/joystick + gf4 happily. hth.

I dont beleave it to be the core voltage if there wasn't enough power the computer would just shut down not cause probleme loading Mup.sys it could freeze at the loading by chance but not every time. As for usb drawing power I dont have any usb devices connected and usualy only have my mouse and gamepad(disconnected them for now). For the cpu core voltage it should not be increased for nothing you should let it run a stock settings if your not overclocking it was designed to run with that setting and should not cause any probleme, however if it does crash because of you core voltage it probably because of you power suply not being able to supply a steady steam of current to you cpu. Stephane ps. I still tried uping the core voltage but it didn't change anything.

first of all, this mup.sys problem is actually not about mup.sys... that file doesn't have anything to do with power functions i tried moving it out of the directory it's loaded from, and the system hanged at the file before that one, so it's more likely a problem with the file that's loaded next, which according to the logs is halaacpi.sys (ymmv) yes this has to be a power thing... additional facts in my case: -my usb keyboard doesn't work -my power button doesn't turn the power off in a single push, you can only turn the pc off by holding it the 4 secs also, i can't boot into win98 but i can boot it into safe mode

Well, I just tried to post a detailed reply to the list and the "Show Preview" button didn't work and erased my whole message. Anywhom, what I basically said is that I have come across this problem with the "ACPI Uniprocessor PC" driver not loading on Windows XP. It occured when the CPU (and AMD Athlon XP 1800+) was damaged due to overheating. Maybe the problem you guys all are experiencing is due to a defective CPU. Just a suggestion.

System was working fine until yesterday. Woke up this morning to write a paper, and god the mup.sys hang. Checked the solutions, and tried the USB card one. Unplugged the USB ports, and it worked fine booting into safe mode. Once I rebooted, however, my monitor was completely blank, and has remained so ever since. I don't even get the standard boot gack. The monitor works fine. Just tested it with a portable. Any thoughts? Windows XP on an NForce2 with a sapphire card. There have been no hardware changes since last night when it worked fine.

Just to add my own experience to this extremely helpful thread: My 2200 AMD box with Radeon 9700 Pro card and VIA KT4 Ultra MB suddenly stopped at loading "the mup" yesterday, I had only transferred some pictures the day before through my USB 2.0 cardreader without any problems. Found this thread, removed all USB devices (installed PS/2 mouse), defaulted the BIOS, disabled ACPI - didn't help, except that disabled ACPI resultet in automatic reboot instead of freeze. Removed my relatively new USB 2.0 card - presto, no problems. Guess I have to be happy with the 4 USB 1.1 and 1 USB 2.0 in the motherboard...

Hi, Just finished reading all this thread. I got the same situation when started to repair one PC. Made lots of test and the conclusion is: 1. After changing high end agp videocard (GF FX5600) with other (GF 2MX400) card the problem was fixed. 2. After checking the PSU data and read the following article about power consuption (http://forum.msi.com.tw/thread.php?threadid=1515&sid=) I noticed my PSU is not enough to power up my PC. This should explain also why there are so different configurations stucked on the same problem. After changing cheap 300W PSU to expensive 350W PSU my problem was fixed and I can use GF FX5600 car .

Hi, Start the Recovery console or.. Start the computer with the boot disks or Windows CDROM After the Welcome to Setup dialog box appears, press R to repair, and then press C to start Recovery console. Choose install Windows and log on as Administrator. At the command prompt type "disable Mup or disable mup.sys" . Find it in windows\system32\drivers "MUP stands for "Multiple UNC Provider" which assists Windows in locating resources when more than one redirector is on a machine such as "Microsoft Client for Microsoft Networks" and the "Novell Client for Novell Netware". Restart the computer and all should be well.

re: Re-Enabling ACPI in my bios fixed it for me.

This happened to me last night. After trying every possible method of booting I googled "mup.sys" and started reading about it. I read through almost all of the posts on this particular thread and was about to try the recovery console...or replacing mup.sys...or removing all of my PCI cards....when I read a post that talked about ACPI. So I went into my BIOS and enabled ACPI in the power management screen. The system then booted up normally without a hitch. I too am using an AMD Athlon XP 2100...and Maxtor hard drives....but it sounds like the ACPI BIOS option may be the solution...normally I would always disable anything to do with power management. BTW: Linux's ACPI driver may not be recognizing the ACPI version the BIOS is using which might explain why one user's Linux machine still worked fine. ACPI starts immediately after mup.sys. Maybe if you have some option set in the OS for win2K or winXP, then something is configured to rely on the ACPI driver starting. If your BIOS isn't responding properly to the ACPI driver, then maybe this is causing all of the system hangs. Moving RAM modules would affect the BIOS detection configuration data so it might be forcing other re-detections ...that might be why moving the RAM modules worked for some people and moving/removing PCI cards worked for other people. ALL I know is that I'm glad I turned ACPI back on before carving up my system with the recovery console or any other hack workarounds. My system is running Windows XP Pro on an Epox 8KHA+ (KT266A) motherboard (Award BIOS) with 512MB of PC2100 DDR (2 x 256) and an AMD AthlonXP 2100+ CPU. A 120 GB Maxtor 6Y120PO EIDE, 80 GB Maxtor 6L080L4 EDIDE, a Toshiba DVD-ROM and a Memorex 52x24x52 burner.

I owe everyone who has taken the time to post a great big "THANKS"! This forum has been invaluable in helping me with my problem. However, I'm still not convinced anyone has it right. I don't know the answer yet either and am still in the midst of a reinstall to see if it fixes it. Here's the background. Put a new Abit NF7 mobo and Athlon XP 2500 in my system. Have a 1394 board, Soundblaster audio/game card, Radeon 9000 Pro 128 AGP, Adaptec SCSI board. Upon trying to boot after mobo install, got the same boot loop hang up after MUP.SYS loaded. I tried all the hardware and BIOS tricks here and none helped. I was REALLY frustratred by the fact that I couldn't even boot from the XP CD! After hours of blown time, I finally noticed that I had knocked the CD cable loose. DOH! IMPORTANT LESSON #1: check connections. After fixing this, I booted to the repair console and disabled MUP.SYS. No luck. I did c:\TYPE NTBTLOG.TXT and noticed that ACPI was the next thing trying to load. I disabled that. Still no change. I ultimately caved and am now trying to reinstall XP completely. With 13 minutes to go, I'm now gettign some install error message about "The procedure entry point Get(UMS could not be located in the dynamic link library MSDART.DLL". Must be my lucky week. More news later...

I have had this problem at least 3 times in the last year and a half. I have fixed this each time differently. The first time I tried the ACPI setting changed and that worked for me. The next two times all of the normal work arounds did NOT work including the ACPI setting change. I got lucky though, I had just done a backup of my Registry in my "System Mechanic" program. It makes a backup of a few different things. I just booted up with a WinME bootdisk and went to the directry that System Mechanic had created for the backup. There was a batch file that restored the backed up files. After I did this I rebooted the computer in to WindowsXP and no problems. No more MUP.SYS problems. So now every time I add some hardware or make a serious change to my system I do a backup in System Mechanic. It helped me again just two weeks ago after I had the system hang in a game. I just kept stopping at the MUPP.SYS during reboot (in Safe Mode). The System Mechanic restore always works. Do not know exactly why, but I love it.

I think this is an ACPI problem as described in previous posts. It is not a problem with mup.sys. In re to prior suggestions, I have an old Compaq with a PIII 800, not an Athlon. It is not a WD HD. I have no USB devices plugged in. The HD scanned ok. I swapped RAM to a different slot, no go. I disconnected CD, DVD & modem to decrease power drain, no go. I disabled everything in BIOS one at a time, no go. I disabled mup, no go. It now hung on the previous step (modem driver I think). Mup is loading ok, boot is hanging on the next step, which I read elsewhere is ACPI related. I reinstalled XP & everything worked ok, all settings were retained. When I veiwed the error log, it was filled with an ACPI error: "AMLI: ACPI BIOS is attempting to read from an illegal IO port address (0x71) which lies in the 0x70-0x71 protected address range. This could lead to system instability." (Wry understatement). I found MS knowledge base article # 283649 which explains this & recomends upgrading the BIOS, which I did. Check the link at the bottom of that page for a more detailed explanation. In sum, I recomend reinstalling XP & upgrading the BIOS. Time will tell if this works. Just my 2 cents. Jeff

I have this exact same problem. A common thread here seems to be the addition of peripherals. A year ago, when I built this computer, I wasn't A+ certified and didn't know anything about ESD. I beginning to wonder if this isn't the slow death of component(s) via ESD? More than likely, when you do get it running, there'll be file system errors sometimes, to the point chkdsk cannot determine the file system, which would lead me to virus/corrupt MBR, yet AV comes up clean... It is very frustrating indeed. If you can afford it, Spinrite (Gibson Tech) is a disk repair utility, that's supposed to help fix this problem

Same problem here. It actually first happened after I installed Office 2003 and the Jet4.0 XP patch. Don't know whether that has anything to do with the problem. However, here's how I solved it: a) escape the d344bus.sys file during safe mode boot. b) rename the windows/system32/drivers/d344bus.sys to something else (or delete it, if you're the Rambo type). c) reboot normal d) de-install daemon tools e) reboot f) clean up the registry (I recommend "RegCleaner". Remove the D-Tool entry)

Fix using System Hive

Posted by Trev (1 messages posted)

Again, thanks to all who have contributed to this thread. I hit the dreaded mup.sys hang - and I hadn't changed anything on the configuration. My config is basically an old Athlon 1.2G with ATI All-In-Wonder + RAID 0 disk setup - I only use USB one device at a time. This thread gave me a list of things to go through - but I was very reluctant to start messing about pulling boards in and out, so I majored on all the BIOS tricks and unplugging USB devices etc. None of these solved the problem, but I did notice that various combinations altered the performance of the machine. I also, thought that I detected a pattern ,during while stuck on the Mup.sys line, of how the machine was looping hitting the hardware - floppy light on, DVD light on, screen blinked, keyboard lights flickered. This led me to belive that it was looping trying to load configuration details, so I just left it to run to see what would happen. Sure enough, I ended up with a blue screen after 5 or so minutes.

I have just recently struck this problem as well. We are currently using a bootable dvd to deploy images on our pc's. The image is setup with mulitipile drivers and can be used on compaq ipaqs, 510s, 530s, laptops and dell gx110 and one other dell. Working okay on all compaqs. Imaged a dell gx110 the other day and on boot up (image is sysprepped so booting to do the sysprep) just dies. Did a safe startup and stopped on the mup.sys Tryed imaging the pc from the test Altiris server and the scripted install works okay is just the ghost bootable dvd with the sysprep that is causing the problem. Only happening on the dells as well which makes me think is a hardware driver type issue. Left pc on over weekend to see if moved on or errorred out but still sitting at the mup.sys file.

I've tried to read through most of these messages. I've even tried most of the suggested solutions. What did work for a brief moment was unplugging all of my USB devices... after unplugging the USB devices I received a error message about severl *.dll files that were currupt. I've reinstalled xp professional sp1, now when it boots up it says "loading your personal settings..." then it goes straight to "logging off..." (it/I went through this cycle 20 times before I gave up) when I clicked on shutdown it just hangs, shut off the PC and when I turn it back on I get the illegal shutdown error, when I boot in safe mode it hangs again at mup.sys. HELP!

After trying all of the non hardware ralated ideas in this thread with no luck, excluding 
resetting the ESCD (which my bios doesnt seem to have an option for that I can see)... 
I tried unplugging the data cable for one of my hard drives (SATA drive if your interested), 
loading windows and logging in, shutting down again, and plugging the drive back 
in (I powered the computer down completely and unplugged the power cable, dont know 
if that helped at all... unless your pc has switch on the psu, your pc will still 
have power running through it even when its turned off, so its a good idea to unplug 
whatever...)

I guess that cleared my ESCD so its probably a problem with newer MS OS's conflicting 
with whatever settings the ESCD has stored (I believe windows 2000/XP use their own 
settings not the BIOS settings, but that depends on what your setup is...)

Pretty sure I know what the problem is-power

I started getting this error after I added a UPS and had my printer plugged in. I 
couldn't figure out why my PC wouldn't boot. Af first it would lock up at mup.sys 
while booting in safe mode. Then it stopped going beyond the memory test.

For troubleshooting, I pugged each component into a different PC. No problems found. 
Finally, frustrated, I sent the motherboard in for repair. It was a Gigabit motherboard, 
one with lots of stuff built in, such as ethernet, sound, usb, com ports, parallel 
ports, etc.

While that was being fixed, I bought a new power supply and motherboard and memory 
and reinstalled XP and all my applications.

Everything was fine for a while, till one day when I turned on my printer. My UPS 
shut down my PC, which told me that there was some issue with power. After that, 
my PC would freeze at the memory test, or go to mup.sys and then freeze. Sometimes, 
it would reboot at mup.sys, and very rarely, it would go all the way to windows. 
It got worse and worse till it stopped booting. 

I swapped the memory slot locations, the power supply, the motherboard, and the case. 
No improvement. 

This manufacturer of this motherboard, ABIT IS7, had their headquarters near me. 
So I took the whole PC there and tested it with the help of some electrical engineers. 
At first, the customer service reps were really unhelpful, refusing to let me come 
in, claiming that the problem was not with their component, etc. etc. They could 
not understand that the problem was not a component, but the combination of components, 
and that I needed to figure out which one to eliminate to get their product to work 
for me.

Anyways, of course everything tested ok by itself. But they could not get it to go 
beyond the memory test until they unplugged all the components. At that point, I 
remembered someone posting about unplugging all the USB devices, so I thought it 
would be good to just boot up with a video card and one hard drive installed. This 
got us farther, to the mup.sys, but it was locking up there. I tried disabling mup.sys 
but it didn't work. (Later found out that I had typed the command in wrong--you have 
to type disable mup while in recovery mode, not disable mup.sys). We tested my CPU 
and memory and boot disk in a different system and made sure they were ok. They seemed 
to be, although we didn't allow it to boot all the way in case XP reconfigured itself 
too much and created further complications.

We tested with another hard drive, and it booted up fine. So we transferred the mup.sys 
over. But this didn't fix it either. I had them upgrade my BIOS (from version 16 
to 18) and then I brought the whole mess home.

After a couple of days of looking at it lying in a corner and working off my laptop, 
I decided to give it another shot, again troubleshooting by removing all components. 
But this time I made a list of everything that had been tried here and decided to 
use the computer case, power suppoly, and motherboard as the base test system. 

I went into BIOS and enabled APCI, or at least the options that I thought would put 
in the settings that XP would recognize as APCI being enabled, as my BIOS did not 
have that specifically. 

I added the CPU, memory, a USB mouse, keyboard, and one hard drive. It booted. Woo 
hoo!

I then added my second hard drive. It worked. 

I then added my internal IDE CD ROM. It worked.

Internal IDE DVD burner. Worked.

I then added my USB devices (2 powered hubs, phone, joystick, 8-in-1 memory reader, 
serial to USB converter, parallel to USB converter, 2 printers, scanner, speakers, 
remote control receiver, etc., etc. It did not work, freezing at mup.sys.

I removed the USB plugs and added another internal IDE controller PCI card that is 
used to control my third and fourth hard drives which I use for backup. Again, it 
did not work, this time freezing at the memory test. 

So, I can currently boot without USB devices and internal PCI cards attached. Once 
in XP, I can attach the USB devices without problem. However, if I turn on the printer, 
there is a clicking noise from the UPS, which tells me there is some power issue, 
although I can't bring myself to call the UPS company and sit on hold and have some 
moron "guess" at my problem.

One other thing I tried was, while booting with a known "successful" minimum hardware 
configuration, I touched one of the internal power connections to the third hard 
drive for a second, even though it was not connected to any controller. The computer 
froze instantly, further reinforcing my opinion that it is a power supply issue.

Also, this explains why different things have worked for different people. Their 
components come on-line at different points in the boot process, and different items 
cause the power level to reach the critical point. Also, electrical drains start 
with a spike, and then level off. So a memory module moved to a different slot will 
cause a spike in consumption at a different time, by which time another spike could 
have leveled off, thereby not exceeding the power supply's limits. Same with moving 
cards to different slots. Same with ACPI configuration settings being detected and 
acted upon.

Incidentally, when I got my system working, I also found out that another BIOS update 
had been posted in the last two days on ABIT's site. I pulled that in, but it did 
not help, even though the documentation for it said that it resolved a "CPU unworkable" 
error for the Prescott chip. I don't have a Prescott chip, but I had been hoping...

I intend to upgrade my internal power supply to the biggest, baddest I can get, and 
next time I will get a quiet one as well. Currently, I have a 350W power supply. 
I am going to look for 500W minimum. I may have to upgrade my UPS to more amperage 
as well, although I am not sure that there is any "conditioning" happening to the 
power if there is no power outage.

I don't think there was ever anything "wrong" with my motherboards except in their 
inherent design of how they distribute power. I suspect that even if I upgrade my 
power supply, the USB ports can only handle so much load during boot. That's a shame, 
but I will research it and if I find any solutions, I will post them here.Maybe I 
can persuade Microsoft to release a patch that will detect all USB ports, but put 
in a delay before powering up each one. They all work once the system is up and running, 
so I think this solution could work.

Just in case you guys think I enjoy doing this, I HATE fixing computers. It's a huge 
waste of time, and if I had the money, I would pay someone else to do it. Like cars 
and appliances, I want to use them, not fix them.

Why can't manufacturers foresee typical power consumption and design accordingly? 
Why can't there be circuitry in the motherboard or in the power-supply to dectect 
and warn about excessive power drain/consumption? 

Why can't there be additional text messages with each file that's loaded...now loading 
xyz, which is used in such and such. In case of the computer locking up while this 
file is being loaded, do this.

Thoroughly ticked off, but relieved that I have access to my files.

Thank you to everyone here for the tips that helped me. I hope my post is helpful 
to someone.

One thing that still confuses me is that the system refused to boot in the base hardware

Another thing I forgot to mention is that my UPS makes a clicking sound when I turn 
my HP LaserJet 4M Plus printer on--it's quite old, about 10 years, I think, and I 
bet it consumes  a ton of power. I just might have to upgrade. 

The printer is hooked up to a different outlet, but in the same room and on the same 
circuit breaker. When I turn it on, I bet the voltage drops and the UPS kicks in 
to boost it. This is probably not too good for the computer--I don't know for sure, 
but APC's site says the clicking sound is from the relay doing either a voltage boost 
(makes sense) or a voltage trim (higly unlikely).

I had the same error that the system would lock up at mup.sys on bootup and the hard drive light would go on every 9 seconds for 1 second and repeat. I went into BIOS on next boot and re-searched for the IDE devices. The secondary master gave a strange line of characters on auto-searching, so I disabled IDE-2 and rebooted. = wallah! = it worked. I replaced the device (a DVD rom) and it has worked since. Hope this helps someone out there.....

I have the same error, but if I let it go for about 10+ minutes, it loads into windows, albeit VERY buggy and very slow. Not really anything at all. I found this thread on google. Unfortunately I can't change my power supply. What seems weird though is that I can run knoppix (linux live CD) without errors. Other than that, I have the exact same problem, and you guiessed it, AMD. It seems this is common, but unplugging USB didn't help. I tried resetting ESCD or whatever, but that didn't work. My BIOS has nothing about ACSD or whatever that A thing was. Nothing I've tried has helped. Once inside windows XP, I can't seem to run System Restore, so that won't help. As well, its very slow and buggy, and Anti-Virus won't load.

This is exactly the problem I had, unfortunately it occurs quite frequently
I can get the pc working for the day by unplugging my sata drive (easiest thing to 
remove), booting, shutting down, and plugging it back in again...
My PC seems to do this the first time I boot it that day, after I have done my unplugging 
and plugging back in, it will work fine for the rest of the day even if I have to 
reboot...
I'm just making a guess here, but is it possible that the problem is a bios/escd 
battery that isnt being charged correctly any more? this would explain why a reboot 
works, but leaving it off for a few hours and then booting doesnt

I upgraded my Athlon XP 1800+ to a 2400+ and flashed my bios to the newest rev. 
Now: 

Regular boot to windows: hangs
Safemode: hangs (after mup.sys)
Boot from windows CD: hangs a ways into the setup process  -- (same place everytime 
no matter what is connected to the system)

I tried every combination of removing hardware/disabling things in the bios and every 
trick listed here, no avail.

Did a little research about this and became convinced it was power,ACPI, or HAL related, 
or else my new processor is broken.  

When starting windows install from the cd.. when it says.. press F6 to load a raid 
etc..  press F5.

It will load something that tells you to choose your system type -- I tried many 
of these options -- same problem... then I tried:    Advanced Configuration Power 
....Computer, instead of ACPI Uniprocessor.  And it worked! Looking around, many 
people with related problems had fixed them by moving to this HAL instead. The setup 
will update your system to use the new HAL and everything goes back to normal without 
having to re-setup windows.. Perfect!

The Bad news: within minutes my computer shut off, and my power supply is now dead 
as a doornail. (another power supply works)

Not sure what this means yet, but I plan to buy a nice power supply.  If that fixes 
it, great.  If it doesn't, I'll try the HAL swap changes to my OS.  If that doesn't 
work, its time to buy new RAM, MOBO, and processor and see what happens.  I will 
mix and match the combinations until I find the god damn answer.  If there is one, 
I will post it here.

If it turns out I can't use this system with winxp anymore, we'll try making this 
box a freebsd server.

This is the most god damn mind boggling problem I've had since the early 90's when 
computers did crap like this on a regular basis.  This kind of stuff may have been 
half-acceptable a decade ago, but its just pathetic nowdays.

By my estimation we're about 3 years out from being able to fully switch to *nix 
as a desktop OS, and leave this crap behind.  Course, just then longhorn will come 
out, just in the nick of time, and it will have features I can't live without, and 
i'll be stuck with this crap for another 10 years.

Thanks. I would like to try this solution. Quick question...do you have to reinstall 
all your applications and device drivers when you reinstall the HAL like this? Or 
does it just update the current installation with the new HAL?

Posted by colby (3 messages posted)

Update to my last post: symptoms appear after upgrading processors or according to 
other users when system hardware changes take place, power usage is changed .. or 
randomly

---------------
My power supply died hard.  I tried a new one .. and it sort of worked but wouldn't 
post.  I left it off for two hours, and it worked perfectly with the new power supply, 
old one is still totally dead.

My theory is this --- the change in hardware .. that people experiences changes voltages, 
and on systems with aging or underpowered supplies, this leads to the problem? Maybe? 
Now it can't just be power related because windows still won't load with the new 
high-end power supply.   But I did fix it, as I'm now typing from windows ---  Here 
is what I did:

Step 1: flash bios to newest version
Step 2: try disabling onboard things
Step 3: remove every optional component in my system
Step 4: Boot from CD to repair -- realize I can't boot from the CD even.. it hangs 
during setup
Step 5: Insert new blank hard drive, flash, format everything, change ram, different 
windows install cd

wtf? I must have a faulty new CPU (nope)
None of these things work

Finally... 
Boot from CD... hit f5 (hidden shortcut) when windows blue install starts and it 
says 'hit f6'
Choose "Advanced Conf... Power " system
(must specifically specify this or it doesn't work)
Note that ACPI uniprocessor pc, is actually for a dual machine with only one processor 
installed. You want the one with ACPI spelled out. (remember the first time I did 
my power supply crapped it self, the second time it worked!)

Then start to setup windows..it doesn't hang! so choose to repair the installation. 
It asks for drivers, so I have to burn them on a cd with a friends computer.  A few 
mins later it bombed with a very odd error box.. and I had to restart.. The next 
time it picked up where it left off and worked.

Then I got back to windows as usual, but it said that I must activate to logon. Well, 
I can't setup the network settings to connect to the net, so I have to activate over 
the phone.  1800 # is disconnected or full.. 
So I have to dial the LONG DISTANCE #.. and then.. painstakinly read this massive 
number to the assitant.  then she reads back this ridiculously long number. 
(note to microsoft, a 500-bit install id does not protect you from hackers, they 
are not using brute force, it only annoys your customers)

I think about giving the nice support girl a giant piece of my mind, but remember 
working in tech support, and know inside that she has nothing to do with my pain.

Then I'm in windows.. Logged in.  I go to windows update. Can't update, system time 
is wrong.  I go to internet time update. Can't update time, date is wrong.  I go 
to my trustly calendar, its april 8th since its 2 am.  I set my date from the 7th 
to the 8th. I update my time.. I go back to windows update.
43 critical updates to install, since it reverted me to pre-SP1, and some of my apps 
don't work.. But all in all, i'm back in action. Go .. turn off system restore, and 
all the other crap.  Install SP1.(just click next, it'll eventually tell you it can't 
install all 43 updates at once)

Get ready to wait a long damn time for the updates.  If you're at a university expect 
to get a virus that's being broadcast to your subnet during this period.. so if you 
have sp1 and updates on a cd.. do that, rather than install over the net, cause you're 
vulnerable again now.

Next time do this: http://www.iamnotageek.com/articles.php?aid=12&page=1
So sp1/2 is on your source cd.

In response to your question, I'm told that you can get windows to do the HAL update 
without the full "repair installation". I just don't know how.  I did the whole "repair 
windows installation" thing -- all my files and apps are in place, and mostly work, 
and many of my settings remained.  But all the windows-updates are reverted, and 
other settings were put back to defaults.  When sp1 finishes installing, I'll let 
you know if everything still works.

to make a real long story short
it turned out to be USB related
unplugged all the usb stuff & it was fine then plugged in 1 at a time till i ran

when i found out which usb cable going into the pc was making it happen i just rerouted 
all of those items to another usb hub now everything is fine w/o having to reinstall

Hello - Just chipping in. I ran into the same mup.sys problem today. Even though I run dual 1.26 GHz PIII-S chips, power is not an issue since I only have a single HDD + single DVD ROM and my case has a 450 W power supply. I had been playing around with the BIOS settings. After several attempts to boot in safe mode, I reset the BIOS to use fail safe defaults. The computer then booted, and I googled for mup.sys, and found this annoyances.org link on Google, and am typing this now. Sonam

I got the same error a few days ago on my xp system. It happened after an incorrect shut down. I guessed it was a display driver problem. Put in an old pci graphics card instead of the agp Radeon and it all came back. Interestingly, instead of resting on that familiar black and white startup options screen it ran scandisk which took quite a while and reported that it had corrected a lot of files. I just put my agp card back and all was fine UNTIL another incorrect shutdown a couple of days later. The same process didn't work this time which brought me to this forum. I tried just about everything here power supply, ram, disabling/enabling in bios and more besides. Knoppix ran perfectly. I then put the disk into another xp pc as a slave to copy my important files ready for a reformat, but it said the drive was not formatted would I like to format it now! Loaded Knoppix on my working pc with the problem drive as a slave and was able to copy my files onto my working drive. So how come it could be seen by Knoppix but not XP as a slave?. The faulty drive is currently back in its home and being reformatted. Still none the wiser! Any thoughts?

response : one way to save ur work is to fix ur harddisk onto another pc..and use tt pc to access information on this hard disk.. else install another os in one other partition u have and u can recover ur data in this partition.

Ok, Heres the thing... I read the whole thread above when i encountered my mup problem and tried almost every fix to no avail. There are a couple of differences that may be of not though... First, this problem started half way through a game of BOTF on the M$ gaming zone. The whole PC locked and i had to cold boot. before the checkdisk came on however my PC decided to reboot itself again which brought me to the safe mode boot option screen. after chosing boot in safe mode the files being loaded would flash past until it gets to the MUP at which point there is no hang no delay just a reboot and i get back to the safe mode boot options. I have not installed any new hardware in the last 6 months (since i bought the pc) so all the talk of it being a hardware configuration change causing the problem is I think inaccurate. Having done some research and talking to several friends we finally came to the conclusion that either the processor or the HD were shot. so... I changed HD to one taken directly from a working machine and connected it in place of the 'suspect'. (This hard drive has been used to test problems on my PC before and has never had a problem booting in my PC). No joy, same reboot at mup.sys. and upon transfering the HD back to the original machine i found that it worked without a hitch. ODD so. I tried the repair from CD but the reboot happened after loading fat files. I did manage to get to the C: propt by trying the 'push F5 during setup' that someone sugested earlier however the way it got there was weird. when i pushed f5 a screen came p saying it couldnt detect the type of pc or i had chosen to manually define my PC type. I had 2 options 'standard PC with i486' and 'other'. selecting 'Other' caused it to ask me to insert a floppy with the PC definition on it (which i dont have and cant find). So i chose the standard option and !presto! repair mode. so. i disabled mup and as many have found mup makes no difference it just reboots on the previous file. I think the conclusion that it has nothing to do with mup is correct. It is also nothing to do with anything on the hard drive. It has to be something in the bios, or hardware. After doing much swapping i have come to the conclusion that if it is hardware it is the processor (its the only bit i havent swapped). I think i have tried every setting in the bios with no results however im sure i havent tried all combinations of settings. The last thing to try before i bin the pc and go and get a new one is to do a virus check from a bootable disk and check the boot sector (and even the bios if possible) to make sure it has nothing to do with any eroneous material on my PC.

First off Colby thanks for you post as it fixed my problem.

"Boot from CD... hit f5 (hidden shortcut) when windows blue install starts and it 
says 'hit f6'
Choose "Advanced Conf... Power " system"

The problem for me being, I needed to change my OS from W2k3 to XP due to video display 
problems with a  new digital TV receiver card. Easy process I thought but after  
rebooting to finish the install the machine kept rebooting with the MUP.SYS file 
being the last file shown in the safety mode boot. I am sure this was not file causing 
the problem as there was HDD access for 5 seconds after this was displayed then the 
reboot.

The strange thing about all of this was I could install XP onto anther HDD using 
the same machine but if I tried to ghost this onto the other HDD that I wanted to 
use it with it would go into the whole constant looping process again.

After trawling through the posts in this forum yours (2nd one I tried) was the resolution 
that allowed me to install on the HDD that I originally could not. 

Once again thanks

Sguilly

Hello, This user I have has SIIG SCSI hard drive and adapter installed. Heres the problem: I have installed Windows 2000 Pro onto a Dell PC. After I install, it hangs @ the Splash screen for Windows 2000. Eventually I get the following error: "Stop:0x000000A(0X0000028, 0X00000002, 0X00000000, 0X8044A9E7) ***Address 8044A9E7 base at 804,0000***...", then it eventually restarts the PC. Things I have already tried: 1. Removed all devices except the required SCIS hardware & Video Card. 2. Tried booting up in Safe mode, it hangs @ Mup.Sys. I am going to try disabling Mup.sys next. Do you know how to get it in DOS Mode to do that? 3. Tried disabling all cache & shadowing in the system Bios. Also tried every boot sequence possible. 4. Tried every option in "Advanced Startup" possible. Is there a setting in the SCSI Bios that I need to change? Is there any trick to installing Windows 2000 Pro onto a SCSI Drive? Any Help you can provide will be greatly appreciated. Sincerely, Scott

MUP.sys - My Problem fixed

Sounds like there are multiple problems, but mine turned out to be a bad second hard drive in my system. The computer just won't boot up with it in the system. I pulled the power connector from the bad drive and everything boots up fine. I'll be returning this one with the bad diagnostics information. BTW, this happened to me about 3 weeks ago and the system starting working fine again the next day. I thought it was a driver problem, but not so... Hope this helps someone else down the line.

It's a NTFS problem. 10 days of trying almost anything and everything. Couldn't load Recovery Console ( system hangs). Couldn't slave the drive ( system doesn't boot). Finally decided to load W2K on a very small HD and was able to see failing drive with no volume information. Then I ran chkdsk D: /f and NTFS errors were corrected. Booted from the corrupted . No problem Good luck everybody. Hopefully this will help. Peter

Had the d344bus.sys issue. I had to reinstall XP, but in the installation, you have pick not to repair the os, but when your format, you pick, leave the file structure alone. This will allow you to at least get to all your data. You might have to reinstall some (most) of your programs, but least you get your data.

Thanks v much to all posts on here. Had same problem on my 98/XP dual boot machine, hanging with mup.sys on screen. Second thing I tried from this thread worked :) superb! Disabled quick POST, but no difference Turned ON ACPI power management in my BIOS and success! Think it was my fault - I disabled it months ago and 98 continued to work by the time I booted into XP I forgot about the change Thanks again Onion

Multiple UNC Provider—MUP Hence, MUP.SYS Basically, MUP.SYS is sent requests to link UNC names to local resources (files and folders). It is used in network situations where UNC is used. The problem arises when MUP.SYS cannot link a UNC name to a local resource (a file or a directory) and produces an error. In the case of startup, it locks the computer. Because of the nature of this file, there is no definitive answer why it causes a lockup. It is generally NOT a hardware error, but that is a possibility. In my case, MUP.SYS was locking up because I corrupted the NTFS partition on my hard drive by using Partition Magic to resize my partitions which did not complete sucessfully. The corruption of the NTFS partition caused a problem linking the files on my hard drive in MUP.SYS. I was not able to boot from the CD because the corruption on the hard drive still existed; therefore, whenever I tried to boot from CD, I would get the same error. The solution I choose was to boot from a Windows 2000 CD (I was running XP), and repartition and reformat the hard drive, and reinstall XP.

I read this thread and mine is *fixed* now :D thanks all. I updated my BIOS from 1.20 to 1.30 AMI MS-6925. My NT 2000 regularly shows all drivers as it loads them. It reached MUP.SYS and then rebooted. I came across this site with the altavista search string: "windows 2000 won't load after I flashed my bios" To fix mine I did exactly this: 1. Unplugged computer for 15 minutes while reading this thread. 2. Switched the order of my 3 memory sticks (PC133) 3. Plugged in system, went to BIOS, loaded defaults. 4. Save&Exit Bios.. continued to load. Viola.. :D

It's the PCI USB card (nothing to do with the MUP.SYS., already loaded..) in WinXP. What it is really, and a simple solution I don't have, but the following works for me with no exceptions: Shut WinXP off, remove the PCI USB card, reboot (surprise surprise, it's completely alive!), run check disk (which will require you to reboot; allow it). Shut Win XP off, insert PCI USB card, reboot, it works again till the next time you shut down. Pros: it works always on my system. Cons: it's long Good enough for me, and I don't turn off.

I was having the same problem which started when I installed an ethernet/firewire/usb combo pci card. My system would just keep restarting. I removed the pci card and it still kept restarting. I then tried a different video card and one by one removed all pci cards with no change untill the last one which was an mn-730 wireless network pci card then it restarted fine. I replaced everything and disabled the wireless network card and system starts fine. With system running normal I enable the network card and within 5-10 sec. computer detects new hardware and then shuts down to the restart cycle. There is an option in the wireless settings for an (adhoc) with that disabled and the card enabled the system works fine the second I select (adhoc) and hit ok the system goes into the restart cycle. Anyone know the cause of this or a way to work around it. For now I removed the wireless network card and am thinking of going with an external wireless router or will that cause the same problem. Thanks, John

I get this same problem however I cant do much hardware changing as this is on a laptop unfortunatly I work at a biotech company and I cannot reformat this laptop as it operates another machine, formatting the laptop would render the machine useless, until we repurchase the software needed to operate the machine I was installin office 2003, and afterwards i went to update it, and windowsxp hung up i restarted it and it crashed, when i start up in safe mode it seems to hang up at mup.sys, and gives a 0x0000000 type of error I read about the hardware changes but i cant do any of those, and oddly enough my winXP cd doesnt give me a repair console option, it just says to run an automated recovery thing, and then asks for some sort of recovery floppy, i am wondering if there is any way i can create those recovery floppies or would that be useless? I am completely clueless on what to do on this situation, any idea's would be appriciated

Hi I was having that mup.sys hang up in safe mode, as i couldn't boot in normal mode. after disable mup, testing all hardware components...it still locks up. so, i took everything out, just the HD and AGP card putted on. i underclocked my amd xp 2000 to 100Mhz fsb because of possible PSU problem delivering power. Memory stick...underclock too. after walking in BIOS settings...i enable IO APIC, and after that, it boots on safe mode, and in normal mode. well...i'm pretty confused, because if i change that setting off, it doesn't boot again. here goes an advice... Don't buy cheap PSU. it's one of the biggest cause, of windows crashs/self reboot. remember that there are 400w cheap PSU that can delivery less Amp than a 300w good PSU. and if you have an AMD or an ATI video card.....they need too much power. Bye

Hi! I stayed up all night and read every single message posted here... I can see there are a lot of souls troubled by this problem (I will name the problem in this way but I'm almost convinced that mup.sys or other system driver crashing is an effect, and not the cause for this issue)... My problem, however differs from all of yours in one aspect... two of my computers developed this problem at the exact same time!!! I bought/built a new computer about 1year ago! Specs: AMD Athlon XP Thoroughbred B 1700+, KT400 Chipset and AGP8x mobo with nothing but AC'97 sound on-board, 256MB DDR400, 40 GB HDD and the nVidia GF4 MX440 64DDR AGP8x video-card... This computer has worked perfectly ever-since... no problems at all even though I overclocked it since the very first day to 2400+(with cooler for 3200+)... About a week ago I bought another computer for my girlfriend and used the oportunity to upgrade my own... So I bought two identical DDR400 256MB sticks, a nForce2DDR400Ultra+MCP+DualChannel mobo, a 2000+ Thoroughbred B, 80 GB HDD and a Radeon9200 video-card... My girlfriends system got all the new parts except for the ram and mobo, which I replaced with the ones I had! I then cleared and upgraded the BIOS on both mobos using the manufacturers specifically designed software and latest updates, I formated and partitioned both the old and the new HDD, and started a clean XP install on both computers... When I reinstall I like to do the job just right and I don't stop untill both computers are ready to use, with all the updates and service packs required, latest drivers and only using licensed software or share/freeware that I know for sure isn't buggy! Everything worked perfectly, or so it seemed... When I was allmost sure I had done everything, I decided to restart my computers and that's when one of them cracked, the one with NF2DDR400Ultra... It went on restart after restart just before displaying the winXP logo and progress bar!!! I pressed the F8 key and got the system boot option menu, and by selecting the Safe Mode I was able to see that the restart happened durring or immediately after loading MUP.SYS... and it kept restarting... I was finnaly able to boot my system by selecting the Last Known Good Config option which I didn't want to try at first because of the posibility of a rollback in some of my last settings and/or installs... Until figuring what the problem was I kept using this boot option and it worked for me every time but it was still annoying... Then my computer started to reset itself... The computer rebooted spontaneously, but without a relevant cause or a specific program running... For all this time (cca. 1 day) the other computer (my girlfriend's) worked fine, but the next day it too started to crash at boot, but without entering the rebooting loop... it just displayed the boot option menu by itself as if it had recovered from a crash, or some other OS error and restartedif I selected any option except Last Known Good Config... In this case also selecting the Safe Mode revealed the last loaded sys driver to be mup.sys... And, also, by selecting the Last Known Good Config I was able to boot into XP... Another difference, appart from the rebooting loop, was that this one did not spontaneously restart, instead it spontaneously freezed... no input available, no mouse or HDD activity... just the hard reset worked!!! By this time I was getting prety desperate, and my girlfriend too... How could this be??? Two different configs with perfectly compatible hardware develop the same issue at the same exact time??? WTF is this??? I then started to demote every possible cause listed on every possible forum or site... 1. The first possible cause listed was USB2.0... FALSE... I had XP SP1 with updates, so the USB2.0 driver wasn't an issue and, furthermore, I had no USB device connected... 2. Then ACPI Uniprocessor PC... FALSE... Everyone I know (50-70 colegues) including myself had used XP before, on TabletPCs, Laptops and/or Desktops, for years even, with the system set to ACPI Uniprocessor PC and this problem never appeared... My mobos have no BIOS option for disableing ACPI OS and that couldn't be the case either... 3. Another sugestion was the BIOS update, clear or set to default... FALSE again, because as I said, I had just flashed the BIOS ROM before installing on both PCs, and, during the "week of fire", as I call it, I reset the bios a tone of times, with only temporary success, as the problem reapeared shortly... 4. Other possible blames were the Office 2003 Suite with SecurityUpdates, Nero 6.3 and DaemonTools... I admit to having both Office 2003 with update paches and Nero 6.3 installed just before the problem first appeared, but I don't think they were the cause, for I have had them for some time and only now the problem appeared... 5. A few other allegations have been made, but even though I understand the frustration and eagerness to blame everything that crosses your path when a bug like this annoyes you, I couldn't help but find them ridiculous... Among these I want to reproduce just a few: 1. Cluttered NTFS Drive... chkdsk /f and it goes away... FALSE!!! NTFS has nothing to do with this... trust me!!! 2. Bad processor!!!... Come on man!?! Do you really think that your computer starts at all if you have a bad processor... FALSE!!! A damaged processor is a rare thing and it usualy happens to be dammaged from the moment you buy it, or it gets dammaged during the cooler installation process... Eitherway this is not the case for computers which have been runing without problems for some time now... 3. Virus?!? The thought couldn't help but cross my mind too, but on second thought... what are the chanses of a brand new PC with no network connection and freshly installed system and software from original CDs have a virus infection??? The answer is simple: NONE!!! 4. Another amateour-like approach of this issue is that of swapping different components between slots, etc... The good news when using this techinique is that by aplying it it's very possible to resolve some problems, at least temporarily, but it will not be a suitable resollution for a problem that has appeared out of nowhere in the context of no logical or physical hardware changes... In my case the true and aparently simple resolution of this issue resided in the Stand By setting in the BIOS setup!!! As a result of updating and clearing and loading the default BIOS settings, I unwillingly changed the StandBy option from S3(STR) Suspend to RAM under ACPI OS to the S1(POS) POS under ACPI OS (which is the default)... I set S3 instead of S1 as StandBy option on both mobos in the BIOS setup and it made the problem permanantly go away... As a true, uninterested and non-malitious pice of advice I would like to say to all you computer troubleshooters out there to stay open minded and try to use some common-sense in your evaluations and conclusions, regarding that matter...

Hi All, Well, I too had the problem concerning XP not booting, hanging up at MUP.sys. I tried nearly everthing suggested in this forum. What worked for me was doing a Windows restore by booting from the CD- Rom. So far so good. What got this ball rolling was upgrading my CPU from a celeron 1.7 to a P4 2.8. The system failed to boot on the first time after the CPU upgrade. Just thought you would like to know........Rob

I did as you said and changed S1 to S3, but no luck for me. However, if I take my power lead out during the mup.sys hang, put it back in and reboot, I get the "last settings" screen - I choose the last setting and it reboots into windows. For me this is proof that the problem is power-related. Is Windows XP having problems with certain types of power supply? I note that one user fixed his problem by change the PSU. How do I find out my PSU type? m

I am prety sure that in my case the problem was generated by Nero 6.3... The main difference between this Nero version and the prev versions is the introduction of a Nero ImageDrive driver that supports *.iso files in addition to the *.nrg allready supported. I am sure that in my case that driver was the prolem, because it appeared every single time I enabled Nero ImageDrive and uppon selecting Last Known Good Config the System Restore Service disabled Nero ImageDrive... I uninstalled Nero 6.3 and the problem never came back!!! Beware of other virtual drive software too... I've heard complaints regarding UltraISO and Daemon Tools too... About your PSU now... I AM SURE that this problem HAS NOTHING TO DO with bad PSUs, but here goes... It is true that a bad PSU is a very serious problem, but the simptoms of a bad PSU are totally different. Problems generally consist of system overheating, system hangs and blue screens during power tasks. SO to be more speciffic: 1. System overheating... 2. Blue screens or hanging durring videogames... (Videocard does not get the quality power it needs...) 3. Blue screens or system hangs durring cd burnning... (CD-RWs need lot of power durring writing...) 4. Bad performance, hangs or blue screens durring heavy multitasking... PS: If you have that bad a PSU I guess your system should't start at all... A mobo can also have some influence on the power your components get, because it incorporates voltage and amperage controllers... To check if your PSU is really bad try entering the BIOS setup and watching the voltages under the System Health menu (or somthing similar) or use a program that can do that from your WinXp environment... If the voltages drop consistently when system activity becomes more complicated then you may have to change your PSU (Antec or Thermaltake produce very good PSUs), but I repeat... THIS HAS NOTHING TO DO with the Mup.sys issue... Hope I've been of some help Regards, SAMmy

Mup.sys hang fixed by moving memory chips
Tuesday, June 15, 2004 at 2:24 pm
Posted by Grad Girl (1 messages posted)

My Windows XP Home Edition computer was having similar problems. Booting into safe mode resulted in hang at Mup.sys. Any other attempts to boot would automatically reboot before reaching any Windows screens. I couldn't even get it to reach the recovery screen with a Windows recovery disk. Switching out the RAM memory fixed my problem.

I just joined the club. Happened last week when my computer fell over while powered up after I perched it somewhat precariously on the edge of a cushion (don't ask). I had also just reinstalled some software, but I can't directly attribute the problem to that. Almost immediately after the fall my computer crashed and then went into a boot loop like many of you are experiencing. A quick peek at safe mode showed me that mup.sys was the last driver loaded before it restarted itself. Anyway, I was without internet at the time and wasn't aware of the notiriety of this problem, so I resorted to troubleshooting with diagnostic tools I had on hand. One of my tests involved popping out all my cards except video, and running memtest86 on my 2 512MB DIMMs. I ran the tests on the DIMMs as a pair in several configurations, and individually. Memtest86 reported errors in every configuration, almost immediately. I then tested my RAM in another machine using the same method with no errors reported. This, was a clear indication to me that the mobo (Gigabyte GA-7VRX) was damaged, so I went out and purchased a new one (Gigabyte GA-7N400 Pro 2). I also bought some new PC3200 RAM because my current RAM was only PC 2100. I installed my CPU, RAM and system drive in the new motherboard and powered up only to find that the computer still hung at mup.sys. I reformatted a spare partition on another drive, installed XP and had a look at my non-booting original partition. everythings seems intact. No aparant data loss, at least. It would appear that the problem with the boot loop has something to do with data that lives on the drive, independant of the system hardware (hence deduced by the fact that the drive is on a system comprised of completely different hardware than it was on when the problem occured). Aaaanyway, I poked around for a while on Microsoft KB and found ties between the "mup.sys" problem and DFS (Distributed File System). It seems if DFS is disabled somehow, then such problems can arise. I don't have any solutions yet but hopefully my continued poking and prodding will yeild some helpfull information that I can share with you all here. Wish me luck.

Hi Bud, The Boot to XP Repair thingy worked for me. Boot from CD, select R for repair then log on to the installation required (usually '1') enter password and type: disable mup (then hit the enter key) a message pops up to confirm the action. type exit to restart the system with no problem!! phew!

Hi Guys,

I am another poor individual with the same problem. I hoped that the amount of information 
on this thread would sort me out, but to no avail.
The problem first arose when I found my PC had hung. So I had to reset the box. It 
has no longer booted since then.  Safe mode shows it hanging on MUP.sys.  I have 
now stripped it down to the bare bones with only the Geforce 4 4200Ti graphics card 
and a Maxtor DiamondMax Plus 9 attached. Still it doesn't boot.  I have tried booting 
from CD and it also hangs when starting Windows. I have tried another HDD with a 
fresh install of XP on and that hangs on the next driver AGP440.sys.  All of this 
is proving to be a little strange. I have attached a HDD with Win98 on it and it 
runs like a dream. I have tried to install WinXP and Win2k from CD, but it is not 
playing the game. The only thing that might have some impact is that my XP drives 
are configured as dynamic disks which is a pain as 9x won't recognise them.
My PC spec is:
AMD Athlon XP 2200+
Gigabyte 7VAXP Ultra Mobo
400w PSU
Geforce 4 4200 Ti
512mb DDR Ram PC2700
Liteon 401 DVD Rewriter

I had a similar problem with MUP.sys. It kept restarting my computer every 15 minutes or so, although this could be a different problem from what some of you are having. But since the trouble was the mup.sys file with me, ill post this solution (by microsoft). http://support.microsoft.com/default.aspx?scid=kb;en-us;824288 the problem is not a hardware problem at all, it has to do with windows SP4. You need edit the registry, but the instructions are pretty straightforward, can't go wrong. It worked well for me. Good luck

Big big problem with mup.sys
Wednesday, June 23, 2004 at 1:39 am
Posted by antoine david (1 messages posted)

Hello, I was just about to shut down my pc when it suddenly stopped , coudn't move the mouse and the keyborad. So I restarted the pc, but couldn't boot and restarted after showing up mup.sys on the safe mode option. I have norton ghost and created a while ago a clean xp install, but still crashed on the mup.sys after aplying the image. So i decided to install xp pro again, but it couldn't even load the setup files!!!!!!!! ME works fine so as 98, but I need xp pro to be back up and running. You may say try installing onto another drive, chaning ram, chaning grapcis card, apply an new network card, disable the gigabyte ethernet option. But all that didn't work. I am been 24/24 on thei problem for 5 days and believe me, my job is to repair pc's and I have never seen anything like that before...! I would grately appreciate any help from anyone, as I am lost. Many thanks to send me your ideas to babeantz@yahoo.com

Hey everybody,
This thread is getting press, because the right answer is contained within it (see http://www.mcpmag.com/columns/print.asp?EditorialsID=729). The ESCD sometimes just needs to be reset, so Plug&Play enumeration gets forced.

The trick then is: how to do this on your particular system?

I don't think this is the final word on the "mup.sys" issue. My bios successfully reset ESCD, and it did not fix the problem. I had two identical computers, one with and one without the mup.sys hang. By swapping hard disks I was able to determine that the problem was attached to the HD. (Diagnostics told me the disk was fine.) My take is that, whatever sparked the problem initially (in my case it was related to putting the system into suspend mode-- I think), it ultimately resulted in something getting screwed up in the system files. A few details: Win XP, Could not even get to Safe Mode, MS support could not help, Tested memory and HD, Called motherboard manufacturer, Reset CMOS, Removing all USB hardware did not help, Moving memory stick slot did not help, Playing with BIOS settings did not help (including power management and plug-n-play), Repair install behaved suspiciously, Finally did clean install. -jw

system hangs on boot at text windows loading screen
Wednesday, June 30, 2004 at 11:05 am
Posted by Mr. Brown (2 messages posted)

OK I have a special situation that seems to shed some light on this problem. I am 
setting up a common image for our campus to use across multiple hardware platforms.
I am doing a sysprep then copying the image to a network volume then porting the 
image to a new configuration this has worked in the past windows 2000 pre sp2 now 
that I am attempting this with windows 2000 SP4 I am getting the dreaded hang at 
mup.sys error (or whatever depending on the last driver loaded).... this is after 
the 4th suscessful move. The machine that is choking is a 1 ghz INTEL PIII (sorry 
this is not an AMD problem). And for those farmilar yes I have imported the universal 
disks  registry files.
The issue is a result of a change in the windows 2000 bootloader between SP2 and 
SP4 (and at some point in XP). There is some kind of bug that does not hand off the 
control to the windows 2000 kernel correctly after some kind of hardware change. 
The bootloader seems to have the same issues in XP. It loads the kernel files into 
memory, as well as setting, irqs, dmas and i/o values. A change that is made to those 
values either either in bios or windows and the loader freezes when it attempts to 
move pass control, this is apparent in the fact that the next screen you should see 
if all works well is the windows splash screen. 
Now I have tried all variations of hardware in the motherboard, including disabling 
everything but the essentials, multiple video cards, harddrives, memory, even identical 
motherboards (different motherboards work fine). Even a bios upgrade this is a intel 
815 motherboard both original and newest bios have been tried. The only common problem 
between all these cases is the hardware handling at the point where the bootloader 
passes control to the OS. THIS MUST BE ADDRESSED BY WINDOWS. There is a workaround 
that we can use in the mean time forcing the system to do a full redetect of plug 
and play be some method (moving/changing/removing hardware enough hardware). 
Windows must fix this bug, but don't expect them to admit that this problem exists 
until they have a fix ready to go. And they are in no rush because if you are changing 
you hardware configuration (drastically at they think but even minor changes can 
trigger this bug) then you must be trying to steal thier software.
Anyway, if you are reading this and you work for Microsoft FIX THIS PLEASE!! otherwise 
I feel your pain.

OK, In trying to do to many things at once: ie adding hard drive and changing the mouse from usb to ps2, my box started to hang at mup.sys brought me to this forum. For sure I thought it was the ide cabling, master/slave config, hard drive was the problem, but to no avail. Alas, I removed the ps2 mouse and plugged the usb mouse back in and voila! Back it prime working order, with the added hard drive up and running no problem. hope this helps some poor soul out there....

Hi I would like to join the group. I read through all the stream and I think I have another thing to add. I have a XP athlon 2000 on a MSI Moboand 6280E a Maxtor + another Drive I Also have a DVD - RW and a CR -RW both connected to a Ulta ATA 133 PCI card (SIIG). I used to have all my system working when because of the latest updates I decided to apply the patches from Live Windows update. I disconnected while the patches where downloaded (few seconds after I started so I thought no changes were applied but it looks like I was wrong). Since that I cannot boot to Windows 2000 with Both the DVD and CD connected . I tried everything : - Bios upgrade -Windows upgrade. -Moving the PCI card. -Move one ov the CD to the on board IDE. no luck. as long I have both the DVD and the CD connected I can't go on the system hangs (it used to be on mup.sys but since the SP3 upgrade the safe mode doesn't show the logs any more. Any idea ?) Note: I moved DVD in all the possible places and it did work. Then I tryed the same for the CD and it did work. As long as I connected only one device it's ok. For some time I also receved the the following message: STOP X1E KMODE_EXCEPTION or the IQL_NOT_LESS , but wen in Safe Mode always the system stopped on mup.sys. To tell more the Stop messages stopped when I changed the P&P O/S swith uin the BIOS to Yes or disabling the Bios Cache. I now don't get them any more (who knows). AnyWay does anyone have a clue of why I cannot connect the Two Drivers ? (is there any conflit in the Windows drivers ? I could I refresh and delete all the CD/DVD drivers from windows and try from scratch ?) Help please !!!!

i encountered the mup.sys hangs up during safe mode too. But the cause is more simply then others in the forum encountered. I just swapped the hard disks w/ XP to another PC, which was both running smoothly before the swap. here is the config for both pc b4 the swap. AMD 2000XP GA-7VA motherboard (gigabyte) 512mb ram 120G maxtor using XP sp1 Intel P3 733 AX34PRO motherboard (aopen) 384mb ram 40G maxtor using XP sp1 AMD works after the swap of harddisk Intel encountered the mup.sys problem (i think it has nothing to do w/ mup.sys, coz it hangs at the previous .sys which is ndis.sys after disable on mup.sys, probably the next driver causes the problem) i also tried what other suggest, by disabling the acpi in the bios, but what happened was the PC starts into a boot loop. hope this will help you guys to isolate the problem. I am still not able to resolve this yet.

I was stunned to see that so many people had the same problem as me... looks like 
the Muppets club is doing brisk business!

Question: did any of you install Trillian Pro (or any of it's add-on components) 
in the days before your computer went off to muppet land?

I clean installed XP twice with Trillian Pro and had the mup.sys problem, and didn't 
install it the last time. I am, needless to say, still running clean after four days. 
Perhaps the mup.sys problem isn't a hardware/xp problem, but rather, a problem resulting 
from Trillian?

I had written earlier regarding the no boot issues. I have an update the issues I 
was having was directly related to the HAL there are multiple versions of the HAL. 
If windows misjudges the abilities of the system bios and chooses the wrong HAL you 
get the hang on boot if you can get in and force the OS to chooses a more compatible 
HAL under device manager, computer, you will be able to get back online. This is 
really something that should be addressed by MS to either give you a better error 
or allow you to select HAL types in the recovery console. Anyway thats what I found 
in they case, Good Luck, Hope it helps,

Hi, I have this problem... It all started when power supply went very low on my house, computer was on while this happened and somehow it screwed my HD, coudn't boot, safe mode resulted on mup.sys hang, can't go to recovery console (it hangs while examining the HD), I tried to install XP again but again it hangs while examining the HD, also tried moving the HD to another computer with no luck, changed the jumpers to slave but it would just hang in the startup in the other machine, tried different jumper configurations and the drive was unformatted (it prompted me if I wanted to format the drive...), I can read from the HD when I boot with an ntfs file reader I got off the web but that doesn't fix the problem. After all that I got here, so I tried swapping memory, resetting BIOS to optimal, unplugged ethernet card, downloading software to test the HD (and every test was passed, even a whole surface test), so I don't know what to do... Someone posted something that seemed very similar to the problem I have with the HD (it was Peter I think), and I'm going to try installing W2K on another HD and see if it can read (and fix) the drive. Any comments are welcome, thanks. Abelardo

I know my post may sound a bit out of line, but I believe it's gonna help someone 
here in some way or another, I can almost guarantee you that one. My trouble with 
XP lasted about 3 days. Specifically, I'm gonna talk about these things:
   - Cloning
   - Mup.sys
   - Activation
I see very little mention of the word *Activation*, but I have to stress that activation 
has a lot to do with hardware! This means that when you mess with XP's activation 
mechanism, then XP may Not even *report* to you that you are tempering with it's 
Activation mechanism, so you could be stuck without a clue for many hours/days. You 
may be left with a hanging screen (typically the Mup.sys mentioned all over here). 
This might also explain why there is No discussion about this topic on MS websites. 
Anyway, why would you expect to find a place for *Activation Bypass* on any of the 
MS websites :-)

My post applies to the following symptoms:
  1. You cloned your XP hard disk to another hard disk and
     now you want to start the cloned XP on another/new system
     which probably has different hardware.
  
  2. You are attempting to start XP on a machine
     where you did Not do the Setup, ie: You came
     with a HDD that already had XP installed on it
     and you attempted starting that HDD/XP on another
     machine (possibly with lots of different hardware).

  3. You attempted re-installing XP from the XP CD onto
     the new system, but still with the cloned HDD in it!
     ie: You Don't want to Partition/Format the HDD and do
     a clean install, because you Don't want to lose your data.

Normally, the new machine should attempt booting properly, unless it really, I mean 
REALLY has broken hardware. if you have broken hardware, then I suggest you test 
the hardware by installing another OS on it. Lindows OS is a very good OS for testing 
hardware,
   1. Lindows OS runs from a CD (No need to install/setup on HDD)
   2. Lindows will test & use lots of RAM, if your RAM 
      is somehow corrupt, you're sure to see Lindows crashing!
   3. Of course Lindows uses the Processor. A faulty CPU chip 
      would Not go far with Lindows!
   4. You VGA/AGP adapter will be equally put to test by Lindows.

Other good choices of alternative OS are BeOS, FreeDOS & Linux. If Lindows (or whatever 
you chose as alternative OS) loads & boots properly, then we can rule out the possibility 
of faulty hardware, at least CPU, RAM and VGA. Alright, let's move on...

From this point on I have to assume that you have No broken hardware. Now is the 
time to come back to XP. 

When you attempt starting XP on the new system, it hangs on Mup.sys (in SAFE-MODE). 
I believe the reason it hangs will be activation related. Remember, when XP sees 
too much NEW Hardware (new onboard chips, BIOS, etc) then it thinks you're messing 
with its activation. You can try to remove add-on cards, disable onboard USB/devices, 
etc. You can even try to re-install XP from the CD or even from setup files on the 
HDD itself, it may still hang at Mup.sys or In fact, when you reinstall, it may hang 
at the Repair screen or some other screen earlier/later than the Repair screen. As 
long as the HDD you're trying to install to has a working/activated installation 
of XP, XP will try to prevent you from even repairing that installation, because 
there is too much New Hardware and that's against the activation law. Ideally, you 
would want to Partition or Format the HDD and then do a clean install (but you obviously 
Don't want to do that!).

My suggestion is actually very simple. It doesn't need all this typing. I suggest 
that you take the HDD back to the original system where it boots properly, or just 
put it into any system where it boots without problems. Once you've done that, just 
start the XP Setup/Installation on that system. To be more specific, copy the setup 
files from the CD to the HDD (in Windows Explorer) and then run XP setup from the 
HDD right there within Windows Explorer by simply double-cliking the Setup.exe file 
(Make sure that you are Not double-clicking setup.exe from the CD or from the DOS 
Prompt, etc). 

What you're basically doing is that you are Re-installing XP, even if you and I know 
that there's Nothing wrong with the currently installed XP on that HDD, cuz it just 
booted properly on this other/old hardware and here you just got to the Desktop, 
isn't it? :-)

When the XP setup begins, you will see it preparing a lot of things and it will examine 
the system and copy setup files, etc. A few minutes later, it will want to **Restart** 
the system for the First Time! Now this is the place where we're gonna catch it. 
When it restarts the system for the First Time, Don't let that Setup to Ever boot 
on that system again! Let it shutdown, but when the system is busy doing the POST 
or loading the BIOS (Before it Boots!!), turn the system off, remove power and take 
the HDD out.

Go back to your new system and connect the HDD in there. Now you should be able to 
**CONTINUE** with the XP Setup on the new system which has Lots of New/Different 
hardware. Now, what's gonna happen is that this XP installation/setup process is 
Not as strict as the other process of trying to boot a previously activated XP on 
a new system (system with Lots of New Hardware). Normally the XP Setup will be more 
forgiving than a cloned XP installation being started/booted on a system with lots 
of New Hardware. Just continue with the setup and let it finish. You should Not Lose 
any of your data & settings (even Desktop settings) since you are simply Re-installing 
XP, you are Not doing a clean-install by Partitioning/Formatting.

Although I put a great deal of typing into explaining this process with so much detail, 
my post can actually be summarized as follows.




On any system where you can boot your XP installation, do so. Once booted successfully and in the Desktop, copy the XP setup files from the CD to the HDD. Run XP setup (Re-install XP) from the HDD from within Windows Explorer. Let the setup run until it restarts the system for the First Time! Once the system has shutdown, cut-off that Setup and go and continue the setup on a new system which possibly has Lots of new hardware. Setup should continue on the new system and it should Not be aware that it's being continued on another system, because it is yet to discover/configure hardware,etc. Continue with setup on the new system/hardware and enjoy. If you have any hardware hang, etc on the new system, then it is time to start removing Add-on/PCI adapters and disabling devices in the BIOS, etc, cuz now you have hardware detection/config problems (don't rush to conclude that you have faulty hardware (CPU/RAM/VGA), cuz then the other OS's above would have crashed, right? or they would have been written by magicians if they could work on faulty CPU, RAM & VGA!). As a rule-of-thumb, when removing hardware/devices, always start with the most luxurious adapters. DVD/Video-Decoder Cards, Sound Adapters, VGA/AGP Accelerator cards, TV Cards & USB Ports/Hubs should be the first ones out. According to me, the bare minimum hardware for starting the system is only 5 pieces... 1. Motherboard 2. Power Supply 3. Video Adapter 4. RAM 5. Screen (Controversially Optional, But how R u gonna see anything without it?) Contrary to popular belief, a Keyboard and Mouse are Not quite *necessary* for the system to start, but I would Love to see a keyboard (even a faulty one, I mean a PS/2 keyboard) causing the system to hang :-) Well, these days there's just so much sophistication. Oh, by the way, yeah, now that we have USB Keyboards, I am inclined to believe that a Keyboard can indeed hang a system within Seconds of starting, ..also one of the posts here emphasized that a USB Mouse can cause an Mup.sys hang, which I truly agree with :-) _______________________________________________________ That's all for now.

Success Story: Thanks to all you posters out there! For me, I was trying to boot into safe mode with a working Windows XP. Like everyone here my installation hanged at the mup.sys line. After reading this discussion thread, I tried pulling out all USB devices on the loading mup.sys line and it continued to successfully boot into safe mode. Observations: My system is fully patched up to July 02 ADODB.stream Windows XP update. When I fiddled with the BIOS, that is I set the: ACPI Aware OS to NO it only made the problem worse. The machine totally hanged on the mup.sys line. Hard drive light did not flicker at all. No system activity was directly observable. If anyone out there has had any success please post it here! Good luck to you all!

Thank you! I've also turned to be a member of the mup-clan. After reading about all the posts around here, I thoughd it had to be a power problem. But let's start at the beginning: The son of a friend of mine liked the lights on my computer, so he turned the PC off and on for a couple of times, te see the lights burning. After that I couldn't start windows XP. In safe mode it ended at the famous mup.sys . I tried to boot from startup disks (both CD as floppies) without succes. After placing the HDU in a different computer, the same problem arrised. But in that pc I was able to boot from CD and do a recovery (after disabling mup.sys of course). After putting back the HDU in the original PC........... no normal boot. Desperately, I wiped the OS partition and wanted to do a full recovery with the disk set provided with the computer.... again no success. The computer halted at the same part of the installation every time. Then I started the recovery CD with pressing F5 during the "press F6 to load a raid etc." message and I choose the only available option. From that moment it seems like my PC knows it's a PC and it works fine.... So thanks again! This really worked for me (though I needed all other suggestions mentioned by others first).

Hey there, Thought I solved the problem, because i could do a full recovery with the original Sony Recovery CD's. Recovering works fine, but after a reboot....... Yes you guessed right.... again the mup.sys hangup. All other solutions don't help, not even automatic repair/recovery.... I'm running in circles now. I figured out this is a BIOS/ACPI problem. Since this is a Sony Vaio PC, no possibility to update the BIOS (it's simply not available). Also no possibility to change ACPI values (blocked out by Sony). I'm desperate right now.... Help!!! Cheers, Paul

I suspect there may be several possible causes for this problem. When I upgraded to a Gigabyte GA-7N400-L motherboard this problem appeared. I did a clean XP install and the problem went away - for a while. When I installed the Invidia nForce driver (option 1 with the motherboard CD) the problem came back. Removing the driver (add/remove sw) totally screwed up the bootup process. I did a new clean XP install WITHOUT installing this driver and the problem has not reappeared. Can anyone see a pattern in all this?

Hi all, I've read all the posts....had the symptoms and here's how I got on. Win2k. Added a new internal CF card reader via my USB2.0 add-in card. Re-booted and it was fine. Re-booted later on and got the MUP hang problem. Safe mode, everything no can boot! Went into bios and forced update of ESCD and re-booted and it worked! Re-booted again and it hung. Forced ESCD update again but this time it it hung. Tried again and it just hung. Update my motherboard bios to newest version (Abit KT7A) and forced ESCD update again and Win2K booted fine. Re-booted again and it's fine. Fingers crossed! Ian.

I got the Mup.sys hang all the time when i started my computer last night and the problem was due to a defective hard disk. The hard disk was on a Promise Ultra 100 TX2 card and the system was hanging when trying to boot, so i tried to remove some hardware from the computer to see what was the cause. tried with the mouse first, no results, then tried to remove the Promise card and to my surprise, it rebooted just fine. then i tried to reconfigure my computer to put my hard disk that was on the Promise card, i connected instead on the sec IDE channel and to my big surprise the SMART from the BIOS told me that my hard drive is going to fail soon and that's what happened, it failed. thanks to all the people that replied to this thread, it gave me some solid hints on how to resolve this.

Ok, I've read through the threads here. Looks like a bunch of people hitting around the subject but not really coming up with a solution to fix the problem. Little bit of history about the issue and the system I built that is having issues with this. I have 2 identical systems. Both home built. Running AMD XP2800, 512 memory, DFI Infinity II Ultra motherboard, 80gig WD hard drive, Sound Blaster Audigy 2 ZS, Mad Dog GeForce FX 5200, floppy, Mad Dog CD-RW and another 52x CD Rom drive. Both systems are sitting in a Thermaltake case. Now here's the thing that blows all these theories outta the water. Built first system and installed Windows XP Pro. System installed and runs fine. Purrs like a kitten. Other system hangs on install at the infamous mup.sys. No problem. Took hard drive from the system that runs beautiful and put it in the other system. Still no dice. Hangs on mup.sys every time. Tried all the different tips here to no avail. Put hard drive that hadn't been able to install in the good system and got XP to install no problems, the good system still purring. Any tech junkies out there got any bright ideas? Have swapped components from bad system to good to see if it is a hardware problem. No dice

I fixed it and here is what I did (to make it work):

1) Googled for hidden setup options.
2) Found out about F7
3) Used it, in the manner F6 and F5 are used.
4) Chose to install
5) Noticed Windows offered to repair itself.
6) Commanded it to do so.
7) Rebooted
8) Rejoiced

If it worked because I used other install media and repaired broken files, or just 
bypassed the ACPI altogether, I do not now. I suggest trying different install media 
if the F7-thing doesn't work.

re: Success Stories - core voltage solved for me
Sunday, August 8, 2004 at 7:25 am
Posted by Paul Marshall (1 messages posted)

My success story:

Been down for around 3 hours with this issue.  My computer reset itself while I was 
working on a Word document.  Since then it was giving this same mup.sys issue.

FAILURES OR FALSE LEADS:

1)  d344bus.sys doesn't appear to be anything to do with this issue.  That driver 
runs Daemon Tools and just happens to be loaded right after mup.sys.  Ignore this, 
IMO.  (false lead)

2)  Resetting BIOS settings to optimal or failsafe did nothing for me.  Same old 
issue.  I even powered off and jumper-reset my BIOS.  No good.

3)  Copying a different version of mup.sys from a working copy of WinXP Pro SP1. 
 No good.

4)  Removing my USB devices.  I only had one MS Force Feedback 2 joystick plugged 
in.  Removal made no difference.

STUFF I DIDN'T TRY:

1)  Disabling mup.sys through the recovery console.  Given that copying a working 
version didn't help, I figured that this was merely a false lead.

2)  Swapping hardware around.  Just didn't get that far.

3)  Playing around with APIC BIOS settings or ACPI settings (either in WinXP or the 
BIOS).  Smelled wrong.

WHAT WORKED:

Upping my core voltage from 1.65 to 1.70.

That's with an Abit KV7 mobo, Athlon XP 3200, 512MB RAM, 420W Akasa PSU, LeadTek 
Geforce FX 5200, Soundblaster Audigy 2 ZS, WD SATA 120GB, Plextor DVD-RW.

NOTES:

My system is running hot - ambient temperature is around 30 degrees celsius and my 
systems are running betwee 40 and 50 degrees.  It's not been this hot all year.

I had problems booting my machine around three hours earlier with disk corruption 
issues around the system restore.  That cleared up (apparently) after chkdsk /f ran.

Basically, power seems to be a common thread (removing USB devices, changing configuration 
of RAM, replacing power supplies, playing with ACPI).  That doesn't explain why reinstalls 
of XP have helped, of course.

I'm around eight reboots on, though, and Core Voltage has been the only thing that 
helped.

Okay here is my problem (it may help other out or not) I have an AMD 2600+ (bart) on ASUS A7V8X-X mobo. I did a clean install of winXP had my cpu set at 11.5/195 (made me at 2.26) everything worked fine.. temp nice no system hangs. So then I installed SP1... restarted. FROZE on mup.sys. I changed my cpu settings back to defualt. 11.5/133 system can just fine i'm able to change the FSB to 177 but anything higher then that cuases my system to lock at mup.sys. I will try some of the tips from this forum.. if i have any sucsess i'll let ya guys now. Thanks

mup.sys hung my win2k, fixed it...

I installed a new win2k on my pc, acer open MK77M-V motherboard, amd xp2400 cpu. After the install I did a reboot and it hung hard on the windows throttle at about 25%. I booted in safe mode and the last driver loaded before the hang is mup.sys I have put win2k on this computer before with no problems. The only thing I could think of that I did different was that I had enabled the chip-away-virus detector in the bios, so I turned it off. After that win2k booted fine, no more problems. Don't know what or why, just know that it fixed my problem.

2. tried to boot into safe mode and discovered that it hung at mup.sys
3. googled mup.sys and read up on the problems people were having.
4. cursed microsoft and burned and effigy of bill gates.
5. disabled mup.sys and reenabled when disabling did nothing.
6. reflashed bios which was allready up to date
7. moved my memory to the other slots and moved it back when it did not work.
8. added a scsi card in hopes of updating ecsd but no luck. (i have no periferals 
and my pci slots were empty. ) i also tried upluggin my usb mouse and disabled onboard 
everything (sound usb firewire etc...)
9. bumped my vcore up a little then back down when it did nothing
10. underclockd my fsb and multiplier.
11. tried to boot from winxp cd which also failed.
12. booted winxp disk by hitting f5 when it asked to hit f6 for some drivers and

I am posting to second Mr. Browns' assertion that this is NOT an AMD problem. This is definitely a Windows problem and I think it is related to activation as moses explains in his awesome troubleshooting post. Like many of you, I have looked desperately for a solution but will end up wiping the hard drive for a clean install. I ran into the situation doing an on-site job networking two computers. Simple, right? Due to this thing we call "Mup.sys" (viaagp.sys and ntfs.sys were also implicated at different points!) I never got that far. Before I bought the hardware I went to look at the computers in question. The main computer is a Pentium 4, 2.40 Ghz with 256 MB of RAM running Windows XP Home edition, built by a reputable local company. I suggested that when I buy the hardware, I also get some additional memory as his Pentium 4 is shackled with only 256MB. Agreed. When I purchased the memory I matched everything except the manufacturer. I popped the card in and immediately got a message that it didn't have a necessary driver. A driver?? I tried again and got the black screen offering safe mode. I selected Start Windows normally. No go. So I took out the new RAM and tried again. This time I did select safe mode and got hung up on Mup.sys. The adventure began, from there I got the hideous constant boot-cycle described by so many. *** I am posting because I did eventually have success accessing the drive by installing a second copy of Windows XP under the directory \WINDOWS2\. On boot up I had the opportunity to select which copy to use, the newer version was the top listing. I opened in to the empty shell of XP but all of the files are on the drive, and accessible from My Computer. Of course, I could not actually run any of the programs, but the reinstall into the "new" windows allowed access to the data from the previous version and, most importantly, let me copy the files there. I am waiting now to meet up with the computer owner on Monday to be sure I got everything before doing a fresh install. I had been swapping components as recommended by many when I installed the second version of Windows using the boot disk. Curiously, at the time the only memory card in the computer was the new 512 MB. So given that everything works fine when I use the newest copy of XP, I DO NOT have a hardware problem - not even with the new card. Before installing the second version, through the Recovery console I tried disabling mup.sys, disk check - which did find and fix 1 error, DFC Client on/off, renaming files and replacing them with good files from the disk, specifically \system32\config\system, \software, \sam, \security and \default. I did try to copy files from the XP disk into the version that doesn't work to re-boot in Internet explorer as moses suggested in his post but I found that any attempt to reinstall installs over the working version of windows, not the corrupt one. This computer initially had a modem card but no others - I ultimately took that out as it is unnecessary - one hard drive, one floppy and one cd-rom. Pretty bare bones. No usb hardware attached. I tried as many combinations in the BIOS as I could paying particular attention to the USB drivers, ACPI Aware O/S, caching and shadowing and SDRAM timing. Resetting or forced update of ESCD wasn't an option. I wasn't able to find information on the power supply but less than a third of the cables coming out of it are being used. While I know this doesn't eliminate the power problem many have suggested, it makes it pretty unlikely. I submit that Microsoft, in their attempts to prevent piracy, included a cynide capsule for the operating system to "byte" when it detected certain parameters such as a different hardware setup. If Microsoft didn't deliberately create the problem then why won't they address it? There are thousands of anguished posts on the Internet and not a peep on the Microsoft website. Hmmm. Byte this...it's time to learn Linux.

I am having the same problem with my computer, however I do not think it is a problem 
with the power supply or RAM. My HDD is partitioned into 4 partitions, two NTFS, 
one swap and one linux.  Windows does not boot on the NTFS partition, RH9 linux boots 
fine on it's own partition, and Knoppix boots from the CD and can access all of the 
data on all of the partitions just fine.
I've tried swapping around the RAM, unplugging all of my drives and whatnot, switched 
the jumpers on the mobo to clear CMOS RAM, and pretty much everything else.
I just recently added the second NTFS partition to the drive and was wondering if 
that could be confusing XP and causing the "mup.sys hang" and if so, if getting rid 
of said partition would remedy the situation.  

Any help would be greatly appreciated.

the following components are on my system (all internal)
- 60 Gb hard disk, in 4 partitions
- CD-RW drive
- DVD-rom drive
- Iomega zip 100 drive
- 3.5' floppy drive
- PCI Nvidia geforce 2 graphics card
- PCI ethernet card
- PCI modem
- 4 USB ports

thanks for any help, and don't forget to remove the capital letters in address if

Happy to say I fixed mine with the help of everyone who wrote on this thread. It seems to me that the MUP file comes in conflict with many different types of problems since there is one problem and many solutions. For me is was swapping out my harddrive into another system and letting it do a chkdsk on the good system discover a couple of bad segments. Then I copied MUP.sys on to the bad drive from the good drive and it works. This is another testiment to the switching of harddrives solution. Good Luck and Patience to you.

I had this problem, although I disabled mup.sys through recovery and it just hung after the previous file. So in my case it was not mup.sys. I tried to re-install winxp home from cd and half way through the install it stopped working. It just sat there saying it was copying files but there was no disk activity. To solve, I booted from win98 install cd to the dos prompt. Used fdisk to remove my ntfs partition and created a new primary partition. Rebooted again from win98 cd and then used \win98\format to format the partition as FAT32. Then I rebooted and installed winxp. When asked whether to convert from FAT32 to NTFS i used last option to install on the c: as is without formating or converting. Anyway, it all installed smoothly and I'm now happily working on fat32 winxp.

Well... It's long time since I've been here. I had this mup.sys lock up with my 120gb HD and was unable to make the HD work for 8 months... But now I may have answere to all of you have this lock up with hard drives... I downloaded program called Spinrite 6.0 and burned it to cd. Then I booted my computer from cd and this great program used 40h to fix my HD.... now my HD is up and running without any mup.sys lockups and I'm happy... Sorry for my very... very bad english but I have been up since I started that Spinrite fix program (40 hours) so this is my suggestion for those who have this lock up caused by hard drives... Fix your hard drive with this program.. It's freeware and proffessional... Now I'll go to sleep... I hope this helps somebody....

I don't know if this is any help to you - I was having similar problems. I could boot into Safe Mode but after windows logo screen on bootup, I just got a blue screen that flickered on my Win 2000 machine. Basically, I 1. replaced the graphics card with another one 2. booted into safe mode with networking 3. downloaded the latest drivers for the original graphics card 4. got rid of the old drivers for the original graphics card 5. put the old graphics card back in 6. booted up normally (which worked!) 7. installed the new drivers It's been working for about 2 weeks now so hopefully there shouldn't be any more problems. Hope this is of some use to you...

Hello Guys, As all of you I suddenly exprienced a problem at startup. I was playing StarWars Galaxies and the games hung really bad. I had to do a hard reset of my machine. After that, it wouldn't reboot at all. Strange because I just installed a new RAM module as well as a new USB printer. So I started to switch the RAM modules between the slots and things like that. Nothing worked, the PC would boot, but the screen would stay black. I read a sh*t load of posts and simply ran a checkdisk. After 15 minutes, the PC rebooted and Windows started just fine. I'm now creating a restore point, because we never now ;-) By the way, I have an AMD 1800+ Hope this helps someone Thomas

Alright, well I'm trying to fix my brothers computer, a7n8x Deluxe, 2800+, and a 120gig SATA HD. It stops at Mup.sys, like all of you guys seem to have problems with. I've swapped around the memory, nothing, unhooked the DVD player, nothing, there are no USB peripherals hooked up, its mouse, keyboard, monitor and thats it. When I try running the recovery console to disable the mup like someone suggested, it starts to analyse the disk and then throws out an error that they shut down windows to prevent failure. ntfs.sys address f74498e9. *shrug* Any ideas guys?

If you read the post, you will see that mup.sys is NOT the issue but the follozing driver after mup.sys. So disabling mup.sys is useless. Try to boot in safe mode and start a checkdisk... For the recovery console, you can also boot with a Window CD and choose "install recovery console" in the menu. After a reboot it'll appear in your available OS choice if you press F8 at boot... from there you should be able to launch a scandisk good luck thomas

Right, the only problem is I can't actually get the Recovery Console to finish loading. From the Windows CD, if I select either Repair, or Install, it starts to check out the Hard Drive. A few seconds in I get a blue screen that says "A problem has been detected and Windows has been shutdown to prevent damage to your computer" So, I can't run the install to do a repair of the current installation, nor can I access the recovery console. Understand the calamity? LoL.. Thanks..

Well,... then you're in a bad situation :-| I remember that I was able to start in safe mode, it was taking ages (10 minutes) but it worked. I notice that because I was reading these posts to fix the "mup.sys" issue on my desktop PC. it was just there stuck (i thought) on mup.sys when suddenly the Windows logon menu appeared. If you're able to boot in safe mode, then you should be ableto run a checkedisk and/or to install the recovery console. If that doesn't work, then I'm running out of option. Take the disk and do a bckup of all personal data onto another PC then wipe it out and start from scratch with a fresh Windows install... Thomas

The common thread to this entire problem is that everyone is using an AMD processor. That should have been the first clue. Intel is the only way to go. The only sure-fire way to solve this is to ditch your AMD machine and buy one with a processor that XP was written for.

Actually, the same thing happens with Intel Prescott Processors on many motherboards. It has nothing to do with the processor ... it has to do with having an old BIOS that doesn't recognize newer CPUs. (And after all the problems I've had with this Intel processor, I think my next one will be an AMD.)

I too have joined the muppet club.
 
My problem started several months ago with my WinXP Pro SP1 computer spontaneously 
rebooting. This happened more and more frequently until something got garbled enough 
for computer to no longer boot. (This computer had worked flawlessly for over a year 
before.) I reformatted and did a clean install of windows, but problem returned shortly 
after. I switched out mostly all of the hardware and decided it must be the motherboard.

I bought a new motherboard & a better video card while I was at it. I reformatted 
and reinstalled windows on new system. This system worked flawlessly for @2-3 months. 
When I came in to work Monday my boss said my computer was off when he came in (usually 
runs full time) and when he tried to restart it it went in to the now infamous boot 
loop. He powered it down and turned it on awhile later and it booted OK. 

I worked for several hours Monday without a problem, but then: spontaneous reboot 
and boot loop. Normal boot = restart, safe mode = restart after mup.sys.

I tried to do a repair from bootable windows CD, but would restart at various point 
in the process. Went into recovery console and did chkdsk /r. It took a LONG time 
at 50-70% and kept jumping back to 50%, but finally it finished and said it had repaired 
some errors. So I reboot and same problem still. 

At this point I decided hard drive was messed up as it & CPU were only same components 
from previous troubled system. Went and got a new 160GB hard drive. Removed old hard 
drive and did a format and windows install on new hard drive. Windows installed completely, 
but after that first reboot resulted in same problem except it was intermittent and 
I could occasionally get into windows. Flashed MB bios to newest rev, still no love. 
Messed with various bios settings, nada. Deleted all partitions, reformatted and 
began installing windows again, went home.

Next day - get to work, complete the windows install. Try rebooting & it works. So 
start reloading software with many reboots along the way. At some point the problem 
returns. At this point I found this forum and tried many of the ideas here. The most 
helpful seemed to be upping the vcore voltage in bios. This seemed to make the problem 
happen less frequently, but it still does @1/4 reboots. Also still has occasional 
spontaneous reboot from windows.

The only thing that seems to be unique in my story is that I tried a fresh, brand 
new hard drive with clean install of windows and still had the problem. My best thinking 
is to agree that it is some problem with the windows/bios relationship, but I have 
no idea what triggered it and still no great solution.

Current system:
MSI K7N2 Delta-L
AMD XP1800+
1GB PC3200 DDR
160GB IDE Maxtor
Nvidia FX5200
Win XP Pro Sp1/2

XP SERVICE PACK 2 Mup.sys issues. Seems to me for all I have read mup.sys hanging problems are hardware/bios related. I have an ASUS P4SP-MX motherboard that workd fine until I updated to XP Service pack 2 then I got the dreaded mup.sys hang in safe mode. I upgraded my BIOS and All was fine. A friend of mine also had the same problem after upgrading to XP SP2 he had to disable his on board USB ports and buy an additional PCI USB card to fix his problem. I guess his BIOS didn’t work with XP SP 2. I advised him to keep a check for a new version of BIOS. If you have an old motherboard it may be time to update.

I had a friend who brought me his machine which bluescreened and rebooted 3 days ago while surfing. Upon reboot, windows XP home hangs with a 5 minute delay, followed by Scandisk, them reboots upon exit. Upon starting safe mode, makes it to Mup.sys, HDD activity, long delay then scandisk for both "Normal", "Safe", and "Last Knaown" Modes. Unfortunately for this person, who bought the XP home OEM version, there is no repair installation option. I tried to remove USB and use "Last Known Good Configuration" but to no avail. Scandisk found several truncated files in the "\Windows\System32\DLLCache" folder. I will end up doing a full reload after I can get his pertinent directories and profile info backed up. The thing that floored me was what happened this morning on my personal machine, running Windows XP Pro, hung upon bootup. These machines have shared no connection or data. My machine has acted a little funny over the last couple of days. I immediately suspected either Spyware or a Virus. Scanned it with everything but the kitchen sink(waiting for someone to port it). When my machine hung upon bootup I tried safe mode. BAM!! HUNG AT Mup.sys (What are the odds?). I have read this problem thread and saw where several people have had luck with removing USB devices then picking "Last Known Good Confiuration" so I removed my Logitech optical USB mouse, and older Acer USB scanner and the picked "Last Known..." from ther boot menu. Windows booted like a charm as if nothing had ever happened. I plugged in my Mouse and scanner, which were immediately detected. I plugged in my scanner(which has been plugged and unplugged many times due to space constraints), last week to scan a few photos. Since the lockups were sporadic and intermittant at best there was no clear cut indication to pinpoint the instability. Incidentally, my machine: Asus P5S-553MX with onboard video disabled P4 Northwood 1.8Mhz (at 2.4GHz stable for 6 months) 400W ATX dual fan PWS 2 x 512MB DDR4000 Kingmax DIMMS @ 266MHz ATI Radeon 9600 Pro All in Wonder AGP 3COM 3C905B 10/100 PCI NIC No modem Creative Labs Audigy 2ZS OEM Promise S150-TX2 Plus SATA/ATA133 PCI Raid 2x 80GB Seagate SATA HDD in RAID0 Lite-On SOHW-1213S 12X DvdRW/48X CdRW Writer Plextor 12X CdRW Logitech Optical USB mouse PS/2 104-Key Keyboard Acer Prisa USB flatbed scanner(when in use) Palm M505 & Cradle (occasionally, hotsync disabled) Windows XP Pro SP1 OEM(Clean Install, Legit COA) XP SP2 *not* Installed Unneccesary startup services, apps, drivers disabled My friend's machine: Abit KR7A RAID 512MB DDR PC2700 Ram (Brand Unknown) ATI Radeon 7500 All in Wonder Creative Labs Audigy 1 Platinum 56K internal PCI modem 80GB ATA133 No RAID Creative 16X DVD reader Generix 32X CdRW Logitech Cordless freedom Optical USB KB/Mouse Creative USB Web Cam Windows XP Home OEM (Clean Install, Legit COA) XP SP2 *not* installed I read 20 threads on MS Knowledgebase also this morning about USB problems and power management and disabled, "Allow this device to turn off this device to save power" In all occurences of "USB Root Hub" in USB Controllers of Device Manager in Control Panel.

Motherboard died so replaced with new - froze on boot. According to safe mode it crashed in/after mup.sys Windows XP obviously had to load new drivers for the new motherboard and I thought that was the problem. But it was a disabled BIOS ACPI on the new motherboard that caused it! I read through all these excellent messages. Re-enabled ACPI. Windows XP settled down to the new motherboard. Noted one thing though... MUP.sys was not only the last entry to run before it used to crash, but it was also the last entry listed in Safe Mode when I got it working - i.e. there were no more entries to come before the desktop came up. Would be more logical for MS Safe Mode to list each process before it attempted it instead of listing it after success, and not to leave any step unlisted. mup.sys indeed gets a bad reputation here.

Agreed, I think we are suffering from a "shoot the messenger" mentality because mup.sys is simply the last item listed when things go sour. In my case, I disabled quiet AND quick boot options in BIOS. After that, lo-and-behold, my RAM beeped a failure code during POST and showed only 20MB system RAM when 512 was physically installed. System booted fine following install of new RAM. BUT, the caveat is that I still had to reinstall XP and all apps following the successful boot because the bad RAM corrupted many files during its failure process...several installed apps (like Office) won't run, and several Windows apps (like calculator, help center, IE) won't run either.

I'm having the same problem on an Abit NF7 S2 board. Boots fine normally but blue screens if I try and boot to safe mode. Last entry on screen is mup.sys. This has only started happening after installing XP SP2.

I hope my over 8 hours on this here is and sharing my SIMPLE solution saves someone major time and stress. PROBLEM: After moving my motherboard and modem card to my new computer case, Windows failed at startup at MUP.SYS. This problem can also be caused by moving the computer and a component (internal card, jumper, memory etc) moving out of place. IMPORTANT NOTES: 1 - The fact that MUP.SYS is the last line displayed means that the problem occurs AFTER MUP.SYS. 2 - My problem was in fact BIOS related! 3 - By removing my card (in this case the US Robotics Modem card) and reseating it into the slot, my BIOS got reset and the Onboard Modem setting was set to internal! SOLUTION: 1 - At startup I entered my BIOS area. 2 - Selected 'Load Optimal Settings' (your BIOS may say something like 'Load Default Settings'. I also selected 'Load Best Performance Settings'. 3 - Went into the 'Features Setup' option and Disabled the Onboard Modem as I am using my US Robotics card.

*****PROBLEM SOLVED****

Okay for me I thought it was because of a progam called Alcohol 120% that was causing this problem, if you get a message when booting in safe mode to "press ESC to stop loading A347BUS.SYS" then you should follow this link. Alcohol-Software Support Forum

It turned out that doing a chkdsk scan found/fixed an error on my hard drive, I did a repair install of windows which asked me for the drivers for my AGP slot (Which I ignored) This install didn't help, I later did another repair install of windows because I read on another forum that someone else had fixed the prob on the second repair install. The only thing I did differently the second time was supply the driver disk for the AGP slot.

So im not sure, if the 2nd repair install fixed it just by doing it twice. More likley my HD was screwed up where my AGP driver was stored and chkdsk fixed the HD and reloading the driver fixed the problem.

I know that this probably wont help some of you who practically have a new computer and still have this prob, but I hope it might help someone. Good luck everyone.

Well my problem of not being able to boot in safe mode with the PC hanging at mup.sys has gone away. I updated my RAID bios and RAID drivers to the latest version and have had no probs since. Very interesting thread this by the way. It has been like walking through a forest with a blindfold on :-)

I had the mup.sys problem. System stopped for a few minutes before continuing. There is nothing wrong with mup.sys it is what happens afterwards. Fixed fault by assigning an IP address to my NIC (192.168.1.1). Looks like there was a timeout looking for a dhcp server causing the delay. I noticed the problem because I tried my cable modem in the NIC port with no IP assigned and the PC booted with no delay.

Hey all, thanks for all the ideas, and I went through a bunch of them, finally gave up, and ran the system repair that comes up when doing a system install. That worked, and I'm back into the system with no loss of data. However, I would hazard a guess that the problem is being caused by a piece of crummy software that tries to load a USB device during system start up. Whether this corrupts the sys file that loads after mup.sys I can't say, however, I do note that I had significant problems with this system in regards to getting a USB 2 Maxtor external HDD to work correctly. In fact, the system tried to boot to the drive, even though it most certainly was not listed as part of the initial boot order in the bios. Also, XP, during the initial system load prior to this problem took a stop error. I generally build systems with an Adaptec IDE RAID card running RAID 1. It turns out there is a known issue with XP and this card, and the way to fix it is to place the card in another pci slot. This is the third system I've built using the MSI K7N2 board with an AMD XP processor. The two prior ran just fine, no problems. Then this one came along. Anyway, the system is as follows: AMD XP processor MSI K7N2 MB 512 MB RAM 2 WD 40 GB HDD Adaptec ATA 1200 The only common factor I'm seeing in all of this, is that it seems to be skewed towards AMD processors. However, it appears we have a few Pentium systems having the same problem, so where do we find the common denominator?

Hi there. My 5 cents worth. Had a computer that had been fried with a power surge and the only part to save was hard drive and CD-ROM. New power supply, mother board, RAM, CPU, Modem. Pretty much bare bones system with on-board video and USB ports. When I put the hard drive in I had the mup.sys hang. This message threads been a life saver. Tried everything here, running bare bones system, power supply was new, changed ram slots, ide drive cables, ide slots, all bios settings, etc. What worked for me. There was one message here from jerry sat feburary 14 and he disabled the APIC mode in bios which allowed him to boot all the way to windows. My APIC was already disabled so I didn't try this and went through the hundred other things to try posted here. Eventually for some unknown reason I enabled it and set MPS version control for OS 1.4. Rebooted and it hung at mup.sys again. I did see a couple of flashes of hard drive activity on HD light. Gave up and reset it all. That flashing hard drive light bugged me so went back and enabled APIC again and when it hung and saw some hard drive activity I walked away and forced myself not to push reset before time. After about 5 minutes it actually booted into windows safe mode where I could do a restore and everything was fine. Went back and disabled APIC in bios and that caused it to hang again. Reenabled and everything running fine. So again we have another message that is a contradiction of a previous message and are no closer to finding the one stop solution to this problem.

Hardware Compatibility List - that's the answer to a lot of these Mup.SYS issues. I found that my Motherboard is not on the HCL. The reason is that it's got some chipsets that conflict with XP architecture. In my case, there's an onboard VIA AGP controller that refuses to allow my Radeon's onboard AGP controller to take control. The AGP controller, as well as the USB 2.0 controller on my motherboard require special software (VIA All-in-One and Southbridge USB2). As long as I NEVER install those drivers, XP doesn't mind my Non-HCL chips (because it doesn't try to use them). However, once installed, they seem to be completely unremovable. WinXP ALWAYS tries to reload them, no matter how brutally or gracefully I remove them, and any references to them. There is no software solution to this hardware problem. If your hardware ain't on the HCL - undesirable results are to be expected.

Hey all, I just had the same problem, a hang at mup.sys. I think the culprit was a new java version I downloaded. I had to reboot after the installation and bam, the mup.sys hang happened. I found out later I didn't really need the newer version. Anywho, I first tried getting rid of the mup.sys then reboot. That didn't work. I tried a restore in safe mode which didn't work. I then went to my other computer and copied the mup.sys from there and pasted it into the bad computers system32\driver file, choosing yes for overwrite. At the same time I did another restore. That worked! So, either the copy, paste method worked or the second restore worked. I am betting on the copy, paste method. So, if you can get into safe mode, get a copy of a good mup.sys and paste that whore.

It took a while to read all messages. Anyway, same problem with me. I will try to keep this simple. The common factors I noticed: 1. Most used AMD processors, but there are some Pentiums in there. 2. Lot of people had this problem after connecting a device, be it pci, usb or 1394. 3. Lots of people got around solving this issue by disabling the anpi (sp?) on the BIOS. 4. Partial solutions involved disconnecting and reconnecting power, changing ram sticks to different slots, and disabling a controller which might have the ! sign on the hardware device, but eventually the problem came back. My situation: 1. Bought a Compaq box, and installed same day a Tv tuner pci card, extra HD, 512 MB of RAM. 2. My PC started restarting at the beginning when it's loading XP. 3. Called Compaq support and troubleshoot the problem to no avail solution. They suggested to take out the extra RAM that I bought and if the problem persisted to take the box to an authorized center. 4. Started troubleshooting with the RAM, taking out the HD and PCI Tv card. Just when something appeared to be the fault of the problem , eventually the problem came back. 5. Managed to get into XP my disabling the anpi thing in the BIOS and noticed that my 1394 controller (managed by the motherboard) had the ! sign. I disabled it in Windows. 6. No problems after that --- but then again this isn't supposed to be happening since I had to disable the 1394 for this conflict to stop. 7. After reading all this posts I figured that the 1394 isn't supposed to be at fault.. it could have been anything from a pci card to a HD to a USB which could be causing the conflict. 8. Unplugged the PC, took out the battery, changed the jumpers from the CMOS to discharge the memory. 9. Plugged back in and now my 1394 is recognized, without a conflict and without the restarting problem. Conclusion: I suggest to read the motherboard manual and look for instructions on how to clear the CMOS memory on your specific case. Do so and try. ps: it took me 2 months to fix this issue without the help from the manufacturer.

I got the dreaded reboot loop on my AMP XP1800 system about a week ago. I read most 
but not all posts from this thread and tried some if not all possible solutions.

I was lucky and XP would start after a few restart loops.  I checked the CMOS changes 
suggested but found my system already had the settings suggested.

I tried a "repair" for XP but things just got worse, I tried a spare HDD and fresh 
install of XP; No good started getting a blue screen crash/memory dump.

Installed Windows 98 onto the spare HDD, still crashed.

After changing out and testing all components I was left with the solution that the 
motherboard (or cpu) was at fault.

I installed a new motherboard and set the CPU external frequency to 133.33MHz as 
per the old motherboard.  Still crashed.  I then tried a Win98 install and got an 
error that Microsofts Knowlage base suggested could be an incorrect CPU external 
frequency. I set the motherboard frequency back to 100MHz.  Things are now stable 
and back to normal except....

My CPU is now running at 1150MHz instead of 1500MHz.

Conclusion;

This was a hardware fault caused by the CPU, although stable now it will probably 
start failing again.

Good luck to anyone with the Mup.sys or reboot loop, this must just be a common symptom 
from many varied faults. 

Only systematic troubleshooting will find a solution although ideas given in this 
thread certainly helped me.
Thanks to all

I've had exactly the same problem as most other posters to this thread: I installed a new ALI chipset USB 2.0 PCI card, and when I rebooted, the system kept rebooting after loading Windows XP for about 20 seconds. I went into safe mode, it appeared to stop at mup.sys, but the hard drive was still going, and it eventually loaded up Safe Mode Windows. I removed the offending PCI card but no luck. The only way to fix the problem for me (I tried adjusting all the various motherboard settings that have been suggested, and I have a 550W very high quality (£70) power supply, top of the range) was to use Automated System Recovery. I put in the floppy disk that this had created for me the last time I backed up the system using it, and it automatically found and installed my saved version of XP, and everything worked fine. I'm now deliberating whether to risk putting the bloody PCI card back in to see if it works okay, but I think I'll just learn to live without it!

Had a similar problem as some listed in this forum: WinXP would get to the boot screen, and then reboot a few seconds into it. I couldn't boot into any safe mode (it hung at the mup.sys stage), and when I booted from a floppy or CD, I couldn't find my C:/ drive. Did all the normal things...removing PCI cards, moving RAM, unplugging USB devices...nothing worked. Finally, I resolved to reinstall, but rethought when, after I booted from the XP disk, I got a message that my machine was already in the process of upgrading (don't know why). Tried the continue/finish upgrade, but that didn't work: I got a blue screen with an unmountable_boot_volume message and some stop numbers. However, that message was progress. I booted again from the XP disk, and chose the exit without installing/upgrading XP. That worked....The normal reinstall files loaded from the CD, and I got to the expected install/repair setup selection screen. I chose R to repair it, but at the DOS prompt, I typed in chkdsk /p and entered it. It immediately started working hard on the first 50% of the drive and took a few minutes. Got a message that it was checking more or recovering. After reaching the 50% mark, it moved fairly quickly. When it finished, and returned to the DOS prompt, I typed in fixboot and entered it. Then entered Yes (for was I sure?). It worked a second and reported it recreated boot info successfully. I exited, and it rebooted into XP like nothing had ever gone wrong. Hope this helps at least one or two of you.

I'm running an athlon xp 1700+ 20gig maxtor hdd 80gig maxtor hdd 128mb ram 256mb ram cd cdr radeon 9200 old via motherboard... I ran it on no cache in my bios. Overclocked it from 1.47 to 1.64ghz for a month or so. Ive had my comp for 3 years and this is the first time Ive ran into this mup.sys crap. My computer would go into "Core memory dump" or whatever whenever I ran a movie that I guess was to much to handle. But as of yesterday I was playing this one movie and my comp just froze. I rebooted to find the mup.sys problem when I did safe mood. Normally my computer would just do a "Physical memory dump" to 100. Whatever 100 meant was the about of physical memory in my processor??? Ive tried most of the other suggestions: Switching around ram, taking off cards, taking off my 80 gig hdd, booting from window xp cd, using chkdsk /r or /f or /p, using f5 and none of that helped. I'm pretty sure the problem is that my physical memory is full and cannot be unloaded. I did a quick reformat on my 20gig since it just holds my windows and other system folders. I did this last night around 1am and it finished around 8pm tonight. Now I dont have iexplorer installed and I cant use the windows xp themes. A bunch of other crap is missing from when the usually reformats. I'm guessing that it is a processor problem and not a mup.sys or power problem. Whatever the physical memory is on my system it was what messed my computer up. :-/ but yea.. doing a format c: got me back into my hdd. I prolly should look into dumping physical memory... and all the problems into that before I reformatted. Oh well. Hope this helps.

I had this problem this afternoon and, like many others here was beginning to despair of a solution. However, it would seem that the symptom is not in any way related to the problem. If XP will not boot (and, as in my case, you cannot even get the the installation CD to install) CHECK YOUR HARDWARE. In my case booting simply hung as AGP440.sys was being installed. Removing that meant it stalled at MUP.SYS. The problem eventually turned out to be a USB Multicard Reader which had had a problem reading a card and was permanently in read mode. Disconnecting the reader solved the problem. It would seem that this error indicates a hardware rather than a software fault, so the first thing to do is disconnect your USB devices one by one and then any other external hardware you you may have. Finally, you may have to start removing and re-installing any PCI cards but that would be last not first unless you noticed a problem with them before the crash. I hope this helps.

My system was consistently rebooting when it reached mup.sys, but only after System Pack 2 for Windows XP was installed. After lots of hardware swapping, repeated reformatting of the harddrive, and several fresh installs of Windows, it turns out the problem was a bad RAM stick (I verified this with a RAM test program available at a Microsoft troubleshooting site, http://oca.microsoft.com/en/windiag.asp -- worth trying, if you're having this problem). Replaced the RAM stick with one I knew was good, and no more problems.

Okay, I have the same problem as described above. The difference is I have placed the HDD in a completely different system. still hangs at bootup. I have ghosted the the HDD to a brand new HDD - still hangs. I have tried the disable mup solution and the reset escd solution. From what I'm experiencing, everything points to the data on the drive. New drive with ghosted image of old one. same problem. known good mobo/proc. same problem. I think the other solutions have been either luck or all of these reported hangs are completely unrelated. Who knows? any thoughts?

Same problem as everyone else. I'm on an old ThinkPad 600E with nothing connected to it(USB, Network, Mouse,etc. The problem arose after an automatic update on 11/12 that had an exit code of 0x24001. Per the log file this update required the box to reboot. It has never booted successfuly since. Selectively disabling services just causes the next on to hang. Any further help or ideas would be greatly appreciated.

Okay folks I too joined the muppets club with a non-booting XP Pro machine. Reformats, new installs, new HDD's did not help. Disable mup.sys did not help. It wasn't his fault. It's a hardware issue that stops the bootup. Odd thing is Win98 ran like a champion on this box. What fixed my ASUS A7V266-E, AMD Athlon1600+, 512 Mb DDR was reflashing BIOS "AND", this is the key. Reset defaults in BIOS. Simply reflashing does NOT change any settings. What I discovered was that the RAM was bad. Or so it seemed. I used the windiag.exe from Microsoft. It tested the RAM as 100% bad. Before I ripped it out and demanded my money back I reflashed BIOS and reset defaults. I also set suspend to ram at S3 and disabled boot virus check. At this point I am reluctant to change it back. So after that the RAM tested good. I reinstalled XP and SP2. All is good. In fact I'm using it now. Not content to leave well enough alone I added my second HDD and set the WD HDD as a master. No boot. Remove the second HDD no boot. Remove the master jumper on the WD HDD and back in business. So mup.sys rears it's little head if anything is amiss with your hardware. The WD HDD jumper does it, so does incorrect BIOS settings. If I learn any more I'll post it here. Thanks to all previous posters who helped me sort this &(*^^ thing out. PJ.

An update. Suspend to RAM and boot virus settings had no effect. Worked fine either way. I did suffer from no sound though. I ended up doing yet another reformat and fresh WIN98 install. This time I made sure the Soundblaster Live was installed and working. Ran the XP upgrade and now it works. XP sure is picky about hardware. Maybe thats why it's so stable once it's running. It refuses to start on a faulty hardware platform. PL

I believe this could be a solution, especially if you are running on a budget mobo or a old motherboard. I have not tried re-setting the BIOS but it did occur to me that it was the one thing i forgot to test, that is the boot sequence...it doesnt make sense, but that was the thing that i actually changed.

OK, Mine is just different enough to kill a few theories. 1. P4 1.8 GHz (Not AMD) 2. Dual Boot with ME on s SECOND DRIVE (yes, ME boots fine-- hardware must be basically OK) 3. Microsoft doesn't have a clue (support told me to back up the HD and then call back--I did using a 3rd party ME package that let me read the NTFS drives) They kept INSISTING ON RUNNING WITH JUST ONE IDE DEVICE FOR ONE BOOT! ***HINT*** AND told me that even if they knew the answer, it wasn't the operating system. Hmm.... 4. Recovery console DID boot off the CD-- found errors on the HD, Checkdisk /r fixed them-- no, it didn't boot 5. Repair boot record and Repair MBR didn't work either. 6. Problem was percipitated by addition of a new bigger HD... BIOS insisted on booting from the fastest (NEW) drive running MAXBLAST3... I think that wrote something to the drive that SHOULD have been booting. The new drive was 0 on controller 1, but AMI decided it really desearved to start; thanks Maxtor. Yes, I got a brief roll on the monitor with an IDE error. No, the power supply is not overloaded (ME works, remember?). 7. Perhaps key. Perhaps a red-herring. I am not 'really' running service pack 2; I uninstalled from the XP 'roll-back' when I saw that you can't disable the upgrade warnings. I think it's in a mixed mode? AMI BIOS, ASROCK G Pro. Very stable for 2 years. Now that I've read this thread, I've got more things to try. Reload is a last resort.

i had this happen recently. i found out that the file being loaded after mup.sys is usually "agp440.sys" i beleive this is where its acutally hanging. i have this issue with xp, and 2000, and in win 98 will only completely boot to safe mode. i think in my particular situation i have a bad agp compnent and just need to turn it off? its not the vid card, ive trie da different one, however i have notyet tried a pci card with the agp controller off.... good luck!

Update: I tried all the fixes suggested INCLUDING a BIOS update. The ONLY fix that worked is at: http://www.digitalwebcast.com/articles/viewarticle.jsp?id=8658 It's a bit tedious, but it really worked. The problem may be percipitated in hardware, but it definately is a file that got overwritten. That link is a good, simple fix for blue-screen of death for a recently working computer. Larry Elie

i just resolved the win xp pro freeze in safe mode on mup.sys line. ***solution*** unplug every USB device. and reboot from a power down (cold reboot, unplug and replug in and turn on). I unplugged my wacom graphire 4" tablet pen input usb device. I read elsewhere (http://www.annoyances.org/exec/forum/winxp/t1047532372) that USB devices can sometimes cause this. ***LESSON LEARNED!!*** figure out what changed in the system. eliminate that change. ALWAYS THINK WHAT EXACTLY YOU DID THE LAST TIME BEFORE THE PC STOPPED WORKING. I remembered plugging in the wacom tablet. Oddly, though, it didn't work and windows didn't even respond. (the wacom was plugged in at the same time as a play station X (1 or 2) usb controller game adapter was plugged in (both are "human interface devices") I wonder if that was a factor. **test my results*** #1 To test this, pluggin in only the wacom board, trying to rebot....it identified the hardware this time....boots fine. #2 plug in ps1/2 usb controler adaptor (for ddr game). let windows recognize it. also plug in the two dance pads into the controller. (just in case that changes anything). i plugged in the tablet into the same usb port as before.... FAILED to boot (hung like normal in the mup.sys ... i could do more, but now i'm going to see if there are incompatibilities with the drawing tablet (see note below) at XP. (note: in every almost every reboot Tablet.exe had an application error when i was shutting down). (fyi: my system is a barebones wintergreen system with 2.0ghz celeron 256mb ram, and a montherboard i don't remember--but it came from tiger direct for $30 after rebate. i'm reusing an old 20gb hd by WD)

My friend bought a shuttle computer in October. He had a canon camera, a printer, 
and a scanner connected to it. Two weeks after he received his computer, the computer 
crashed and entered an eternal reboot loop. When tried to boot into safe mode, it 
hung at Mup.sys. 

He brought the computer to me, I tried to run recovery consule. Did not work. Couldn't 
find the hard drive. Then I realized that he had a sata drive and the drivers need 
to be installed separately from a floppy disk. Well, he did not have a floppy disk 
on his computer. So I slipstreamed a new bootable XP disk with sata drivers. Well, 
then it went through the loading files etc and stopped while examining the drive, 
never gave the option to "repair". I tried to reset the bios, disable USB control 
(his USB is hardwired), everything everyone had suggested. Nothing worked. Finally 
I used partition magic to format the drive, partitioned the 80G HD into a 20G and 
60 G partition and the installed the windows on the 20G partition. 

Then I did a image of his system, and stored it on the 60G partition. Well, it worked 
like a charm for two weeks and then same thing happened. I restored the operation 
system from the image. It worked, then stopped working again after a couple of weeks. 

Now I have restored the system 4 times and figured that it is getting ridiculous 
to do this over and over. Plus I really want to see what is cuasing the memory dump. 
So I decided to do something different.

1. I tried to do an image of his bad operation system so I can analyze it somewhere 
else. Well, it gives the warning that the cached was not flushed on the NTFS system. 
Then operation was aborted due to a sector error. 
2. partition magic can not resize the partitions in anyway. 
3. Bartpe can not access c drive.
4. partition image does not work.
5. checkdisk does not work.

all right, I am running out of ideas. 
Then I read somewhere about KNOPPIX so I grabbed the iso and burned it onto a CD. 
For the first time in a week, I was able to see all the file contents in his HD, 
both partitions. I tried to go to the system recovery information folder and restore 
the system setting using those files but did not have the permission. I guess I can 
try to run samba server and use my laptop to grab all the files.

Anyhow, then I ran ntfsfix /dev/sda1. It successfully corrected the flag and some 
other stuff. Then I tried to boot from the HD, chckdisk started automatically, found 
a bounch of errors, failed to correct the file record segment but repaired the index, 
then unexpected error, then restarted, then chckdisk, then restarted. I put in the 
windows XP CD and the recovery console booted up but then hung while checking disk. 

I think I am going back with grabbing the memory.dmp file and just restore the operation 
system from the image. 

What I suspected happened was the XP did not flush the cache correctly during hybrination 
(my friend said that he always put the computer to hybrinate, which might be bad 
 with XP), then some sectors got corrupted. When it got really bad, then the system 
just stopped functioning all together. 

Any other suggestions? I am really getting tired of looking at this computer.

Now that i've overwritten the bad hives with fresh ones from C:\Windows\Repair, I tried booting it with no luck. I can't get into any of the F8 boot options. No USB stuff is plugged in, only monitor, mouse, and keyboard. I haven't put any PCI cards in yet. If I try safe mode, it gets past mup.sys, but ends with a screen with a Windows XP logo and circles. I think it's an anti-piracy feature, of course, this is a legal activated version that was OEM installed by HP. Microsoft has gone overboard with it's zealous "anti"-piracy measures and I can't boot my computer in any shape or form. The only XP files I've copied is the XP registry which I will bring back once I can boot my computer. I think windows is freaking out over that. Does anyone know how to prove to windows that you're not running a bootleg?

Attention please.. This problem is windows bug. The registry setting about mup.sys is that mup.sys is file system.. Run "msinfo32.exe", and look at the system drivers. You would seek this setting. mup is set file system. Of course, mup.sys is not file system. Microsoft was wrong. And you took the problem. Windows has many another problems. ========================
