my pc automatically turns off suddenly.

Check power supply for capacitors which are blown up, or even better check the capacitors with ESR meter for low ESR, and check for low capacitor value. Is it an ATX power supply? Then it looks like the aux power supply is weak, that often happens when the power supply is not switched off with the mains switch but only put into standby mode (by software).

Re: pc - turnoff

The top messages are right, but in most cases, it may be a cause of a virus trying to reboot your computer at once. May be it is hiding somewhere in your hard disk drive...

If it tries to shutdown for just about 50 seconds: Its a problem, that virus loads and reloads each time you boot your PC (Try to back-up your files on a seperate drive or disk (optical disks would do) and reformat your infected hard disk.) That would fix it (It happened to my friend before)
