sorry i am new i have never used a forum before. anyway like i said i am running the ati 9600 pro with windows xp pro 2.4 g pentum 4 and 2 g of ram. so here is the problem. when i go to play high graphics games like hl2 or bf2 building, veichle, and other thing in the background will just sudenly go transparent. the game play starts to get a little jumpy but not to bad. so i was wondering what is causing this and what i can do to fix it.
