You actually just reminded me... there's a couple of caps swollen on the motherboard and I have to replace it. I have run many memory, cpu and system burn-in tests. When they actually complete they can't find anything wrong... however, most times they lock solid randomly in the test.

The corruption happens randomly as well... usually not coinciding with a lock.

If I were to reboot my system and do a full scan, XP would "fix" the problem files (by deleting them). If I were to reboot immediately after windows would insist on scanning again and it would find more problem files.

I have a new Motherboard, CPU, RAM and aVideo Card that I will hopefully be putting in this weekend but I fear the same problem will persist. I guess I'll update when I get the job done.

Thanks for the suggestion.
