    I was at my parents house yesterday helping them with their iMac and when ever its rebooted right near the end of the boot up it looks like this

    Is this something to worry about? It the graphics card going already, it only happens during boot up and its only there for a few seconds.

    Artifacts on Screen

    My Mid 2011 21.5 iMac displayed a similar image one time about 2 weeks ago. I have no idea what caused it but, It has not returned.

    When I reboot my parents iMac, it happens every time. Hopefully its not a graphs card issue but if it was, I am sure they would see it happen when on websites as well.

    It won't hurt anything to boot that iMac to the built-in hardware test.
    Restart, holding the D key (D for diagnostics !)
    You can run both the standard and extended tests.
