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.
