I'd uninstall Dx8 using the Ebrink uninstaller:
http://www.ebrink.com/dxun/Direct.htm
and re-install Dx7.0a:
http://mssjus.www.conxion.com/downlo...US/dx7aeng.exe
Dx8 is not properly supported by NVidia drivers yet and is causing a lot of problems (as a new Dx always does). You don't need to install Dx8 until you install a game that requires it, and the only one I know of is Mechwarrior 4.
Fair warning, backup your registry before uninstalling Dx8.
Use ONLY the latest NON BETA NVidia Detonator reference driver (6.31):
http://www.nvidia.com/products.nsf/h...etonator3.html
It should work fine with the 6.31 driver assuming the card's not defective and the AGP bus is setup properly.
Some other suggestions:
- If you upgraded from another video card, make sure that no utilities for the old card are installed or are running in the background.
- If you have a 3Dfx card before and you were using the WickedGL miniport, uninstall it.
- DO NOT enable AGP 4x - many mobos don't support it properly.
- In BIOS, make sure "AGP Aperature" is set to the default of 64, "Assign IRQ to VGA" is enabled, and both "Video Ram Shadow" and "Video BIOS Caching" is disabled.
- If you're over clocking either the CPU or the vid card, don't and see if it corrects the problem.
- Make sure your AGP bus clock divider is set properly.
Hope this helps...
