Try this, it worked for me:
Goto Device Manager and delete (or uninstall) the voodoo 2 card listing.
Also in Device Manager, goto System Resources and Delete Plug and Play (it will reinstall).
Then reboot your machine in Safe Mode (yes, you have to reboot in safe mode, hit F8 while rebooting will get you in safe mode.
Then goto Device Manager, look for Video Devices or Video Multimedia controller or something like that, you will see it. Then delete it.
I recommend downloading the drivers first and decompressing them, so when you start back up, you can use those files.
