Hi everyone,
In case you're in the same boat as pcwiz1234, here's a detailed solution:

3. Expand Display adapters then right click your video card, from the menu, select Uninstall. Place a check in the box Delete the Driver software, click OK.
4. Do Not Restart the computer if prompted.
5. Run Nasty File Remover 0.7.x and remove all remnants of NVIDIA drivers.
6. Reboot the system into Safe Mode.
7. In Safe Mode; Install the nVidia drivers.
