This is a head scratcher.
 

XP Pro, 32bit

I'm getting a BSOD loop on boot. The BSOD is a generic error and just gives a couple of memory adresses and says a driver might be bad or the drive full. The Bootlog doesn't log a single thing. I could boot into Safe Mode but then I tried a repair install, which of course gets the same BSOD and I'm now shut out of safe mode. I've done a ram test, I've disconnected everything non-essential and tried 3 different video cards, but it just won't boot. I did a scandisk when I could get into safe mode and the primary drive was fine. The owner has already decided to do a fresh install of Win7 but I'd like to get this up and running while the new OS comes in from NCIX.

System:
Q6600
Asus P5KC
2x1GB DDR2
250G WD Sata
160GB WD SATA
Sammy SATA DVD±RW
Asus 5850 (also tried HD3870, HD4350)
550W Enermax PSU, rails seemed OK

Do a test install on another hard drive to make sure its not the motherboard or bios. If that succeeds, its just a corrupt OS. Not much you can do other then a pave and burn. If it doesnt, cmos reset. If that fails, I would suspect the mobo.

Interestingly enough, as soon as I installed Cat 10.1 under Win7 it hangs up on boot. So I went in and manually set the PCI-E clock to 100 and it seems to have gone away, guess the auto setting must have been overclocking it,

I had a similar issue, after many, many days and hours of trying I booted in to Safe Mode (once it allowed me to!) and did a System Restore.

This was the last thing I thought of it and it worked the first time...shocking how simple some things can be. :biggrin:

Have you tried to boot from a Live CD (ubuntu or similar)

Probably a corrupt OS.

I would try other memory stick to see what happen here. Some time memory pass memtest but they fail in windows.
