    iMac booting issues

    Apologies if this has been asked before, I've trawled the forum to see but couldn't find anything similar!

    My iMac will no longer boot up. It will not even get to the users screen.

    This is the screen it gets stuck on, as you can see there are weird yellow-ish pixelated stripes on the screen too??

    Any ideas guys? Thanks in advance for any help!

    I would suggest that this is an issue with the Graphics System on your iMac. If that is the case, the only real option is to take it to an Apple Store or reputable reseller to get it checked out.
