This question applies to the comp in my sig. I have a weird problem that I wanted to run by everyone. When I run games like Supreme Commander or Warhammer: Mark of Chaos on the highest resolutions that my monitor will handle, my computer will eventually just shut off. I have narrowed it down to the graphics cards. They are not overheating and I have no problem in 3dMark. If I lower the resolution, it takes longer for the shutdown to occur. And now I am down to a resolution that seems to not have the problem. But does anyone know how I can resolve this. Is it drivers? Usually games just crash but this problem just shuts the whole computer off. Thanks for any advice.
