Not good your Radeon HD 6630M GPU has failed! This was a common issue in this series Macmini5,2. The Macmini5,1 and Macmini5,3 both use the Intel CPU HD Graphics 3000 and don’t have this issue.

You’ll need a new logic board, heres the guide to replace it Mac mini Mid 2011 Logic Board Replacement. You may want to look for a used system as it will likely be cheaper.
