auto restarting PC
Yesterday my computer worked...
Today I slept to like 2 or 3 pm...
Meanwhile was my litle sister watching cartoons from internet(duh it was on morning)...
Now when I start my PC then, after loading that snake thingy, when desktop should appear then it restarts and loops until false 
I'v aleady tryed changing settings in BIOS, tryed old values, best performance and opimal values... no effect...
As i know there may be 3 mistakes:
Computer is infected with virus.
hardware temperature is too high.
Or error in software...
I'v had this problem 2-3 times before, 2 time helped format c, and some times just changing setting in BIOS(i mentioned above) helps, sometimes just it restarts and restarts and if I got lot of luck it goes in...
and CPU temp was 32 C, system temperture 32 C aswell,
Hardware is pretty clean, all seems to work propely...
Last time when i tryed to fix it I didn't got op system installed, i took PC to my computer teacher, he said there was error in BIOS aswell... and my install cd was damaged lol 
EDIR: Bios got reinstalled...
and I wanted to say it's usual my computer gets shutted down wrong by my idiotic mom, she just pulls cable out of(that thing whats in wall)
EDIT: So how do i fix this...?
EDIT: I'v tryed safe mode and last known good cfg aswell, but same result
EDIT: Rofl, i got enouch luck and computer went in! woo!
