Can you translate the AMD Error message?
Make sure your GPU Card is not overheating or Overclocked and your PSU is outputting correct 3.3v/5.0v/12.0v voltages.
Is the AMD Driver installing successfully or are you getting an AMD Installation error?
Did you use DDU (Display Driver Uninstaller) with the internet disconnected and AMD Installation Folder at C:\AMD deleted before installing the AMD driver?
