My computer shuts off when I play MMORPG's

Okay so I already know its not a heating problem, why? Well first off I can play any FPS game fine. I play combat arms A.V.A. and Starwars Republic Commando and even Halo, but If I try to play an MMORPG like Lotro perfect world or face of mankind it shuts off. Not like goes through the windows process like loses power shuts off. I also notice I have to unplug the cable and plug it back in or wait for like 30 seconds to 1 min. for it to actually turn back on do you need my specs and stuff or what? any help is appreciated thanks.

 

Well for one, Games like Combat arms, A.V.A, SW: Republic Commando and halo don't require as much power as Lotro. Lotro is a big world, lots of details and overall, a whole lot larger than the FPS games. Perfect world also is a big map and can use up a lot of power. I honestly believe it is an overheat inside your system, but one question. Do you get any bluescreens? Or every time it's just "Lights out"?

 

Yeah I guess your right thanks for replying btw and nope its lights out everytime.

 

Yeah true, and its no blue screens nothing lights out everytime.

 

ignore that its lights out evertime and yes maybe it is a power supply thing.
