    Why is my iMac crashing??

    The grey curtain lowers on the screen it it says it has to restart? This is a new computer... The Apple phone tech says its a kernel panic, but has no clue beyond that.

    Any input is helpful.

    here is the crash report:

    I suspect the "soundflower" driver is doing something incorrect; try removing or disabling it.

    One of the first steps in debugging a kernel panic is to disable or remove any 3rd party "utilities" or drivers.

    I agree to start with the Soundflower driver, never heard of it do you know where you got it from?

    KP's can be tough to track down, they can be caused by hardware or software. If the driver isn't it then please use the articles noted below to help you troubleshoot. Also keep in mind if you upgraded the RAM that is a common cause. KP's can be caused by:

    1. failed RAM (yes it can fail)
    2. Incorrect RAM (did you upgrade, if so double check to ensure you got the right stuff)
    3. Unseated RAM. (simply remove and reseat)

    The articles I'd suggest can be found at:
