After playing call of duty 4 or gta iv, or other graphics intensive games for 20-40 minutes my computer will freeze, black out, the graphics driver will reset, or a few times it will blue screen. I'm pretty sure it's over heating, or theres a bug in the vram.
Is there any way to fix this without getting a new graphics card. (If i did it would be nvidia 9800 gt 512mb, would that work with my psu?)
