Need a bit more specifics on the issue. You have Windows 8.1 installed? What specific driver from AMD are you trying? or.. what specific driver from Samsung?
Ideally, you want to use Samsung's driver. If they only provide a driver under Windows 7, then you're kinda stuck. Stick with Windows 7. The sticky on uninstall/install steps are about as thorough as we can do. If install issues persists, sometimes a reinstall of C++, .NET or even the OS is required to correct issue preventing a clean install.
Catalyst 13.10 Beta supports Windows 8.1. Catalyst 13.8 Beta and 13.4 WHQL did not.
