MY dilemna is similiar to the original. I recently downgraded my PC's video card a version (because the other one fried) assuming that no problems would arise. I had this video card originally and I knew that all my games etc... would run on it. After the switch I go to play something not even graphically intense, Halo 1 to bespecific. It would load but the video was completely gone. The picture was almost non existent. All my games were similiar, it didn't crash my game but I was stuck on the menu and the picture was gone.
So I checked using DXDIAG. I tested the 3d to find the errors. Direct 3d 7 worked flawlessly; 8 and 9 however were the areas where the problems were. I was wondering if there was a way to remedy this. I even tried reinstalling Directx entirely. I am currently running on a Nvidia Geforce 4 mx4000 and the most recent Direct x. I'd really like some help
