My computer just randomly restarted on Friday around 10PM and it won't boot anymore. It detects everything, but it just stops while trying to load from the harddrive. It doesn't do anything but just stay there on the screen. At first I thought it was the virus I was IMed with I accidently clicked(Mozilla asked me to download, I clicked no, then Norton Anti-virus caught it, even though I tried not to download it), but I decided it couldn't be that since it was caught by Norton Anti-Virus. But on my BIOs, everything under the BOOT tab seems to be gone, nothing there, it used to have harddrives and CD options there. Since the motherboard's been out of stores forever, I ordered a new one. Anyways, could this have been a virus? Should I format my old drive before installing my new motherboard? Anyway to remove it?
