I know is not a Virus
There is a possibility that your house power is bad. This can cause the PC power to shut down. If you notice the lights flicker, that indicates bad power. If this is the situation, you need an Uninteruptable Power Source - a UPS. This plugs into the wall and your PC plugs into it. It provides battery backup when the power fails. You could also have a bad main board. I would look into the power situation first, as a bad mainboard is a pain to deal with. Good luck!
when it shuts down.does it just go straight out or does it go click and then tries to restart itself. It could be that you need to reset your bios.
here is a guide on wiki how to do it. http://www.wikihow.com/Reset-Your-BIOS
