Black Ops, PC restarts

So, game loads fine, then i click to start campaign, first cut-screen appears, then it stucks and pc restarts, tried like 5 times, 1 of them i could play first mission, but after that it got stuck on second cut-screen and restarted.
Tried re-install, updating drivers, directX, vcred, nothing helped.
Btw: using SKIDROW version.
Radeon HD 5600.
