    Hi there,

    The last 2 days my iMac has completely frozen on me at random times.
    Frozen meaning, no mouse movement, no keyboard activity (caps lock not responding) and no OSX activity whatsoever.

    Temp at the time 41C, CPU Usage at 21% or smth, Fan speed at around 1200rpm.

    However, I don't get the infamous kernel panic error.
    I haven't changed anything hardware wise. I did have a couple of months ago the graphics glitch problem.

    Last software update was the iWork one.

    iMac is aluminium 20' with C2D 2.4 and ATi 2600 Pro.

    Thanks for your feedback. Much appreciated.

    If you're using a wireless keyboard/mouse setup it might be time to replace the batteries. If using a USB wired setup, try going into Safe Boot and see if anything happens in that state. Also consider running the hardware test on the iMac or just booting up to the disc and see if the keyboard or mouse go wonky there. That will tell you whether its a hardware or software issue.

    Good call with the wireless, but as I said there is a complete OS X freeze happening. I am using wired by the way :)

    Since it happened at random times I don't see how it will be easily identified while running on Safe Mode.

    I did run the 1-3 minutes hardware test (hold down D) and didn't come up with anything. Would you recommend I go ahead and do the full 1 hour test?
