Which version of Windows are do you have installed?
Where are you downloading your AMD Drivers from?
When you remove and install the new AMD driver use DDU (Display Driver Uninstaller) in Safe mode (Best method) or Windows Desktop with the INTERNET DISCONNECTED.
Delete C:\AMD installation folder from the Root Directory of Windows.
Once DDU reboots back into Windows Desktop after removing all traces of your installed AMD Driver, download the Full AMD Driver package and install it. Still with the Internet Disconnected.
Once it installs correctly, Reconnect the Internet and again delete the AMD installation folder at C:\AMD to save space on the HDD/SSD and to prevent future conflicts when updating the AMD driver again.
