    I am worried that something may be on the way out on my mid-2011 iMac. A little bit of history. It recently had it's HDD replaced and Apple for some reason decided to replace the LED screen as well as they noticed problems... heh? I never noticed anything... anyways...

    The last week at random times this has been happening. The vertical lines are not always the same. One time I had a white / grey screen with pink thick vertical lines.

    Weird. Anyone have any idea what could be going wrong?

    *Update* p.s. when i hard reset the iMac it works again. But who knows when i will suddenly get a white screen of death.

    Looks like perhaps your GPU may be on the way out., if you have applecare (and its still in warranty) I suggest you contact apple
