How to Install AMD Drivers Guide @ OCC
 

The installer should begin installing your software. At points, the installer may appear to freeze, but do not be too quick to assume so. Sometimes the installer will freeze for up to five minutes, depending on the speed of your system. The screen may also flash or go blank during the installation of display drivers. This is usual for the installer -- don't worry, it hasn't broken your computer, however you might have to rearrange the icons on your desktop afterwards.
