text: I agree partially with the post above.  You should uninstall the drivers you have by going to Add/Remove Programs in the Control Panel.  You should see something along the lines of NVidia TNT Drivers or whatnot.  Reboot the computer.  A generic windows driver will be installed so that you can still see the desktop, but it will look like crap.  Go to www.nvidia.com and download the latest drivers for your specific adapter.  Once installed, reboot the system if it doesn't reboot automatically, then when you get back to windows, right click the desktop and go to properties, click the settings tab, and reset your resolution and color depth as necessary.  You can also click the advanced button and tweak your refresh rate and other video settings here.  good luck.\n\nI should add that you can also uninstall the drivers using the device manager...but the add/remove programs method will help ensure that all registry entries and whatnot are removed.  This helps eliminate compatibility issues with later driver versions.
