hello there .. I have a note book with AMD radeon HD 7600M when I put it on high performance for a game a black line interrupts my screen and I can't play ..
when I put it on power saver it works GREAT !!! I could run old games on the power saver mode without any problem but the new ones don't work fine ..
I went to every computer repair shop and didn't find the problem PLEASE HELP 
thank you very much
