Sounds like a faulty installation.

Did you uninstall your old drivers before installing the new ones? Or did you just install the new ones over the old?

Just to be safe uninstall your video drivers. Reboot the comp and when it detects the "new" hardware point the installer to the new drivers.

To be extra sure you should get this program, http://www.drivercleaner.net/, and flush out all your old drivers and crap left over from previous installs.
