I desperately need help finding out what is causing my computer to crash to a black screen. It only does this during most games and when it happens there is no warning. The screen goes blank and the sound stutters on and on. I've tried different PSU's watching my temps(they never go into dangerous area. I just need help deciding if the problem is my nearly brand new graphics card or possibly my motherboard. Any help would be greatly appreciated as I am at my wits end.
