one thing you can do is to try a a different version of driver and see if that helps get rid of your issue. also check out www.majorgeeks.com and download "driver cleaner" and use it to uninstall the videocard drivers and install a different version.
i believe the program comes with instructions. good luck and feel free to post back if you got more problems.
