Why does my screen go gray
iMac 20" A1224 (EMC 2133)
At start up my monitor has vertical lines in red, yellow & gray.
When it gets to the point where the sign in screen should show, the screen turns gray.
I had to force it to shut down with the power button.
Any idea what it is? How do I repair the problem?
Is this a good question?
