What's wrong with my computer?

My friend's actually. When he buaght the game Black and White 2, it never worked with his Geforce4 mx 64mb DDr, but WoW worked fine. When he buaght his new BFG 6600 GT OC 128mb DDR and try to run Black & white 2 it worked but after playing for awhile, the screen turns black and says that he needs directx 9 or somethin, but he does have the latest version of direct x. When he ran WoW going into the game it kept freezing, he has to turn off the addons off then it'll run good. The only thing I can think of is the PSU or maybe its the 6600 GT that defective, but I want to make sure because I don't want to waste his money.

Oh yeh I'm not sure if it's the right motherboard, when the computer is turned on it says K7S41GX. I used that CPU-Z program and it also said K7S41GX, I googled K7S41GX and it said ASrock K7S41GX so i thought that was it. The AGP info on the ASrocket site says AGP 8X/4X 1.5V PCI 2 slots, PCI 2.2 AMR 1. But when he first buaght the computer he took off a sticker that was on the agp slot that said 3.3V, so im confused
