Game problems

My computer keeps messing up when I play a game, even on the lowest quality.

It always does that. I can't even get past the character creation in Fallout. It does he same thing for Oblivion and Bioshock too. Does anyone know what this is? 

But I only get maybe 5 minutes of play time. Can it overheat that fast? It's not that dusty inside. How do I change the fan speed? And I think I have the newest drivers. And how do I find my specs for my PC? -_-;

Actually, my friend found one for cheaper that should work just as well. Thanks, though ^^
