I have a friend whose computer has been acting really slow. It started after he tried updating the drivers for his graphics card (ATI X1300 Pro). Then, some rendering seemed to be very slow (web pages displaying and desktop refreshing). When he tried to activate a screen saver, it said:
Could not find any compatible Direct3d devices
He also had this in his DXDiag log:
Display Tab 1: No problems found. Direct3D functionality not available. You should verify that the driver is a final version from the hardware manufacturer.
He has tried reinstalling the drivers a dozen times and using Driver Cleaner Pro in safe mode after uninstalling the video drivers and restarting the computer. He has tried using ATI's method of removing the drivers with the uninstall utility. He has also tried reverting his drivers to an older version. He can't do a system restore because it always says that the system restore didn't restore successfully. Any help is appreciated. Thank you
