Hi

Recently I have been getting this weird problem, when playing some graphically demanding games, my pc blacks out for a few seconds then comes back, and sometimes this happens continuously while playing. So I don't know what is actually the problem as I think I have a fairly good pc, please help.

PC Specs:
CPU Intel i5 2550K 3.3Ghz
RAM: 8gb
GPU: Gainward GTX560 Ti 1gb
PSU: Corsair 550w
