HELP! Problems installing my Radeon / problem with DirectX
I just bought a 1650x pro Radeon graphics card and im trying to install it. After downloading the newest drivers from ati and installing them.. i try to play games and it tells me fail to render. So... i ran dxdiag and i did the 3d test.. it comes up on all 3 tests Failed on stage 8. I tried to re-install directx and that didnt help. Previously i had a geforce-2 and i uninstalled the drivers.. but when i popped the ge-force back in.. i guess it still picked them up. So when i went to the device manager and tried to right click and uninstall, it tells me failed to uninstall because the item may be needed to boot the computer. I have tried all that i know to my knowledge, can anyone help me fix this problem? Or have any suggestions as to what i can do?
