Computer auto shut off

[turok_t]

I was just in the middle of playing Crysis 2 on my computer when my computer automatically shut off all of a sudden. I tried to turn the PSU on/off, reset the CMOS and the computer still doesnt boot. Any clues? Thanks

what kind of overclock were you running? and do u have a spare graphics card to try out (i ask since unpatched crysis2 can kill a card by blowing the pwm on the load screen)
