i recently just got a built by ati 9800pro and i had the 3.2 cats so i updated to the 4.4's and now im getting weird checker board flashes across my screen when i play utk4 JO demo and BHD, i tried unistalling and going back to the 3.2's and 3.9's but im still getting this problem and i made sure the card was fully in the agp socket
