Hi sas02 and welcome to the forums

Try rolling back the graphics card driver to that which came with Vista (see the following tutorial). You will need to restart with each roll back. When you have done this, restart your PC and log into an account with administrative credentials. You should then be able to download and install the driver (link given below).

Hi sas02,

The latest WHQL driver for your system is 175.19. There is another driver available, but it is still a Beta driver (177.92). When it receives its WHQL certification, you should be able to install it without any problems. Remember to roll back your current driver as advised in my previous post before you install it. This removes settings in the registry pertaining to your old driver which might cause installation problems for your new driver should they remain.
