Video setup problem

I have a computer that I am having video problems with. The error I keep getting is

Display:
The driver file that displays items correctly on your system isn’t working….(It then goes on to tell me to reload the driver and / or search MS website)

I have tried to reinstall the video drivers for the original Nvida Riva TNT2 64 AGP video card to no avail. So i replaced the video card with a Diamond Stealth 2000 PCI video card. I still get the exact same error.

Any suggestions?

AMD 1800+ w256meg RAM running Windows ME
