I just recently reformatted a friend's hard drive after her computer was boggged down w/ viruses. I copied what she wanted saved to another computer, formatted her hard drive, installed Win98SE, and copied her stuff back over to her hdd (after doing virus scans on everything). After putting the hdd back in, her computer has started rebooting itself out of no where. Everything seems to be plugged in fine, although I'll double check that the CPU fan is working properly. Does anyone have any ideas? She didn't have this problem before.
