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
