It certainly didn't solve mine. Nor did any of the other fixes listed here. It's
odd - it still reboots just after mup.sys loads.
Athlon XP Socket 754 3000 processor.
EVGA Nforce 3 Motherboard
Twin WD 320 SATA Drives in RAID 1
420 Watt PSU
AGP GeForce 6800 Graphics Card
Lite-ON DVD Writer.
This shouldn't be overloading the PSU, I don't have any USB devices plugged in (keyboard
and mouse are PS/2 connections). I tried every setting in the BIOS I could think
of, to no avail.
This is a new machine, fresh install of windows. Windows XP Pro installs perfectly,
reboots to start itself and goes into MUP failure mode repeatedly. I have installed
windows a total of three times to no effect.
I have no USB Devices, so that solution is out.
I reset the CMOS jumper - no effect.
I pulled the memory in slot two, and ran it alone in slot one (there are only two
slots on this board). No effect.
I tested the memory overnight as well with memtest86 - it says the memory is just
peachy.
I tried a different PSU (this other one was known good at 400 watts). No effect.
I replaced the hard drives with a pair of WD 160 SATA and installed windows on those.
No effect.
I replaced the processor with an athlon 3200. No effect.
I replaced the graphics card with a known good PCI card. No effect.
So, I think this precludes ALL of the solutions listed above in this particular case.
Got any more ideas? It seems apparent that this failure is more than one problem,
since different fixes work for different people. In my case I physically replaced
ALL the hardware in the machine except for the mainboard - so it HAS to be the culprit
here. I doubt I can find out exactly why this is the case, but I'm fairly certain
at this point that I exhausted all other possibilities, with the possible exception
of the metal casing.
And to paraphprase, once we elimate all other possibilities, whatever remains has
to be the truth.
Try the fixes people have had success with, but don't forget that in the end, hardware
failure somewhere is more than a strong possibility.
