A friend on mine's computer all of a sudden just keeps restarting. Cannot load windows, gain access to the root directory, etc. Sometimes the boot screen will show up, other times, it won't. Checked the bios and everything looks fine there. I even changed the boot drive to the CD ROM, put the XP disk in, but it still does the restart thing. Once in a while, a BSOD will flash momentarily, but can't read what's on there....too fast.

I put in a new power supply cause his was awfully hot. Figured it might be because it was over-heating. But that was a no go as well. I cannot access his floppy drive either.

No new hardware installed in over a couple of months....so, I figured that can't be it. I even unplugged all peripherals except for the video card, sound card, mouse, and keyboard.

I am totally stumped....anyone have any ideas?
