I have a m4a89gtd pro usb3, but I´m having problems with the installation of my chipset and video driver, the last time I didn´t install de driver of the chipset, only the video (ati catalyst 10.6) and the effects of aero works perfectly, but this time I´ve installed the chipset before catalyst and give error after reebot, ATI driver is not installed", something like that it says, I tried driver sweeper to clean the rest of the componentes but is the same if I uninstall o back to install, any suggestion?
