This site has a link to Nvidia's site for your video card. Looks like you just need to download the latest detonator driver for the TNT.
Download the driver, then on your computer go to "start"-->"settings"-->"control panel". Click on the "System" icon, then the "Device Manager" tab. Open up display adapter on the list, and uninstall whatever drivers you find in there. Reboot, windows should then be using some default driver, don't let it install it's own. Instead install the driver you just downloaded from Nvidia's site, then reboot again. Once back, you'll prolly need to change your resolution back to what it was. Goodluck!
