    Hi all,

    My iMac will not boot anymore. Just after the Apple logo, the following screen appears, and the computer freezes.


    History is I added an SSD drive in the optical bay - but that was 6 month ago. Anyway, I have had my mac opened. So I wanted to check if all cables we still well placed and everything looked fine....everything but this cable:


    It is the first/upper one to detach. Seems I have somehow ruined it...or squeezed it.

    But what can I do? Can it be that cable...I have used the mac for six month without any issues...until now.

    Just found this cable is that the one I should buy?

    Thanks for any thoughts or recommendations...

    Regards The Dane!

    That's the cable, but not sure if thats the problem. Almost looks like video card may be over heating. I had similar symptoms with my Early 2009 iMac with a Radeon 4850 and before it got too bad I removed the heatsink to the card to reveal that all the thermal paste on the chip had dried up. I cleaned it up and put it back together and its been stable as a rock. I also added a fusion drive setup to it and it works great.

    Something to try anyway. Good luck!

    Thanks for the tip. I tried to unplug the V Sync cable but the computer acted the same.

    Your post must have been right about when i decided to get it repaired, so I did not get to checking the graphics card.

    I ended up going to a local Mac repair shop here in Denmark (Humac) but they will need some days before they get back to me...

    I will update here when I get the result.
