I know this is going to sound dumb but here it go`s.I have sapphire R7265 it is running at stock.I have a old screen so I have to use an adapter too connect it too my gpu.Now when I play games I see like white ghost like lines on the screen,Itis not artifacting cause it does not affect the game at all.I have read that it can be the adpater cause it has to convert the signal.I think of buying a new screen that doesn`t need the adapter would that help?Also I was playning homefront only and the screen just went into power safe mode black screen what can that be?all the parts in my pc case is all new except the harddrive.
