    My 2011 iMac 27" crashes a lot. Ever since I bought it new back in 12/2011, it's been crashing at least 1 to 2 times a week. It happens typically when I wake it from sleep, or while the computer is being shut down. I called AppleCare numerous times, but they don't really have an answer for me. At first, I thought it was Lion, but since then, I have re-installed the OS a few times, and now running ML, which I have also re-installed a few times. No luck so I don't think it's the OS nor software (it crashes even before I installed any 3rd party software). My system is up-to-date, and have tried PRAM reset, repair disk, repair permission. The only thing I added to my system is adding 4 sticks of 4GB RAM (16 GB total). I ran the Apple diagnostic tool a few times, including the extensive test, and did not find any hardware issue. I only have a Drobo 2 connected to my iMac via FW800. I really don't know what's wrong with my computer. My previous Mac (2008 MBP) was running solid, but this iMac is driving me insane.

    My iMac just crashed again. Just before it gave me the kernel panic, screen saver was running, and I was entering my password to log back in. Then grey screen of death. Below is the crash report. Do any of you know what it means? Any help is greatly appreciated. Thank you.

    Try it with the original memory.
    Also check to see if you have added any software since it started to do this.
    Have you checked the video card drivers.
    Have you done a HDD diagnostic check?
    Are there any overheating problems, do the fans come up in speed?

    Maybe again a complete system rebuild.

    Sounds like a memory issue to me also. I agree with trying the original memory for awhile and see if anything changes.

    +1 on the memory. If you got the timings off or are using crappy RAM, then you're probably going to have issue. Revert back to the original RAM and see how it goes for a while.

    I don't think it's software related. It crashes even right after I clean installed the OS, and before installing any other programs. And I don't hear any fans kicking up so I don't think it's overheating.

    How do I check the video card driver or run a HDD diagnostic check? Is it part of the Apple diagnostic tool? I know Apple did a recall on the 1TB hard drive for iMac that were shipped before 7/2011, but I don't think it applies to my machine since I got it in 12/2011.

    I don't know what I did with the original RAM. I just submitted a warranty request. Corsair will ship me a replacement. Hopefully it'll resolve the issue. Thanks everyone.

    I knew it. I should not cheap out and buy Crucial instead. Hopefully the replacement will work out. Otherwise, that's another $200+ upgrade to replace the 16GB I have :(
