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.
