My computer is constantly shutting itself down, but only when I am gaming. After playing a game (e.g Brothers in Arms) for maybe 15 minutes, the computer just turns off!! It is getting really annoying and I'm worried the computer could be damaged if this continues. I am guessing this problem is heat related and I was wondering (Since I have no knowledge in cooling) if anyone could help me find compatible cooling hardware for my computer, or even some tips that don't involve $$. Any help is appreciated, and I can provide all system specs and temps if needed.
