My computer would suddenly shut down as if the power was switched off. It would then turn on and start from scanning disk. Someone suggested that i had virus on my machine and i just bought Nortan Antivirus to clean them out. But it still happens from time to time. Any one has any clues?
If you're sure you don't have a virus, then you might have heat problem
or a power supply problem, some other hardware problem, or a driver
problem. My computer did the same thing and it was the fan (heat) and
power supply. Diagnosis can be complicated. Unless you're sure of what
you're doing, you might consider having a pro take a look and diagnose
and possibly repair. If you want, you could start at the link below to
see if there's anything you can figure out yourself. Good luck.
