Drivers can be corrupt, the reason to do it is to clean the old ones out completely and get a fresh install.

You can also look over the settings, perhaps SLI is activated, even though you only have one card and not using it this can cause troubles. So turn that off if possible. You can also turn off any other settings that are set to be forced if you have and see if that helps.
