PLEASE HELP! i just bought an ati radeon hd2600 pro agp when i play games, it freezes in a black screen! the first time it happened it showed "the blue screen of death" it stated something about bios and ati3duag.dll i tried what it said about turning off shadowing a chaching under bios memory. i read somewhere that there were two updates to install that would fix it and it didn't work!!!!! please help! im out of ideas. btw. call of duty 2 and nfs carbon work fine. two games that don't work are nfs pro street and spiderman 3. possibly updating to vista fix it? HELP!
