Alright, this time my brother's graphic's card is on the fritz. He has an MSI 6600GT AGP. I just reformatted and reinstalled Windows, installed the Nvidia drivers, and installed BF2. Still didn't fix it.

The card runs everything fine and will run most of the other games, but sometimes those game will also get messed up after playing for so long. Today I'll be grabbing another AGP card to see if it works, but my question to you guys is, what caused the problem? His processor throws out a lot of heat and right now I think over time this affected the GPU.

What do you guys think happened? Too much heat? Conflicts with another piece of hardware?
