I have a mid-2011 iMac that seems to have gone wrong?!
When turning on the iMac, a black screen with white lines appear after the loading bar and apple logo have gone.
The screen has also flashed in a sort of strobe affect!
Another thing that has happened is that the display has split, almost as if you are running two displays so you can pull what you are doing from one side to the other.
I believe this is a graphics issue. The GPU is an AMD Radeon HD 5970M, i have also seen that there has been recalls of this model becuase of this. I should go straight to Apple? Or is there alternative resets i could try?
