I'm having a gfx driver problem too. I downloaded the latest, uninstalled the old one, and then installed the latest. But before it asks to restart, I always get the message "This system has not been modified. To install this program at a later time, run the installation again." So after I restart, New Hardware Found pops up. I did this several times and the same message always happens. Whats wrong here.
