I can not get any Catalyst after 7.6 to work right on my 1650Pro AGP. They all refuse to even load a 3d app. Revert back to 7.6 and all is good. Any ideas? I'de really like to update my drivers.
Try 7.5 again, sometimes these things happen. Also, forget CCC, and use ATI Tray Tools. Next time you download drivers, get the smaller one without CCC.
