If is doesnt have an uninstall button go to device manager, I cant remember how to get to it right off the top of my head but it should be hard to do, you can start with right clicking on my computer > Properties. go down to display drivers and select the Radeon driver and delete it click refresh and it should ask you to restart. Then windows will try and install the built in radeon drivers. If your card was an upgrade and a self install, get the CD and put it into the CD-Rom drive after the restart. then Run the setup on it and follow the directions. After you install the original drivers do a cold restart, acutally shutting off the computer and turning it back on, then try reinstalling the updated drivers. But for best bets to upgrade, use the windows update utility, that will automaticly scan your computer for necessary updates and get you the right ones.

Hope this helps
