    I'm from China and My English is bad,so reply me if you don't know what I'm saying:)
    Yesterday when I'm watching some videos on my mid-2011 iMac it suddenly went black screen with no sounds. I waited for like 5 minutes and nothing changed.
    I pressed power button to let it reboot,and a grey screen appears after the apple logo and the spinning circle.
    Tried to do everything like safe mode,reset PRAM SMC,boot up from install disk,boot up from Recovery disk,etc.
    I can get into singleuser mode and repair disk,but nothing happens.
    I remember iMac mid-2011 has some graphic card issues and hard disk issues so I was wondering is it hardware problem or software problem.
    Anybody have same issue with mid-2011 iMac?
    Or also stuck in grey screen after the logo?
    Do you guys have any solution?Please tell me!

    try to use the recovery partition, or to startup from another attached disk, and go to disk utility and check repair disk.

    All these are useless,but when I go to apple store they tells me it's a graphic card problem and they are gonna fix it for free.

    If it's a 27" with the Radeon 6970M card, Radeongate hit your Mac.

    It's covered under an extended repair program by Apple, so you can have the card replaced without cost.
