Black and white bare across the whole screen
Hi there
Last year I bought an iMac around September time and had no problems at all with it until now. I was on it completely fine and went out to do something came back and found black and white bars across the whole screen! I can still tell the computer is on as if I put my password in I can see it go to my wallpaper. Anyone know how to fix it?
