Ain't the fan...

   Well, I tested the video card again and the fan on it seems to work just fine. I don't suppose that is the source of the problems then. Hmm. I even tried an older version of the Catalyst software/drivers and that didn't make any difference either. I might try some other things. I don't know what I plan on trying, though.

EDIT: My brother suggested that perhaps a third party cooling solution was used on it. Thus, when they put the stock heatsink/fan back on they did it incorrectly, causing it to overheat. I suppose I'll be focusing on fixing that. Perhaps I'll even try running it on another computer to see if it exhibits the same problems.
