I have this pink horizontal line that keeps appearing across my display when logged in my computer, starting up, and even when shutting down. I was playing a computer game(in full screen) and when my computer went into sleep mode the game froze. So, when I force quit out of the program this pink line appeared. Please help, I have no idea how to get rid of it.
Can you give me some suggestions on how to remove this annoying pink line?
although I would use a screen shot to illustrate what I mean, the pink line will not show up on the screen shots for some reason.
