Just installed the Elsa Erazor X2 video card and the Turtle Beach Santa Cruz sound card to my system. Since then i have had video problems with any applications that use Direct3D mode. Whenever i run games like Diablo 2 and Motocross Mania (just to name two) i get flashing and flickering polygons/lines all over the screen. I have the latest drivers for the sound card, the video card, and i flashed the BIOS to the latest version. I also just installed the Klipsch 400 speakers also if people think that might make a difference, which i doubt. Any have some ideas?
