We've seen a troublesome issue occur since upgrading recently to Snow Leopard. The iMac will freeze at random times. The mouse pointer simply stops moving - no spinning beachball. The keyboard also becomes inactive during these freezes. The only recourse is to reboot... which solves the problem... for a while. Within a few hours... and totally at random... the mouse will freeze. It doesn't happen when the mouse is moving, just after periods of inactivity (sometimes just minutes of inactivity - not enough time to initiate the screensaver).

I did boot the computer into Safe Mode and the freezes did not occur for two days. As soon as I booted back in normally, the freezes occurred within 2 hours.

Any ideas greatly appreciated.

Thanks,
~Rick

    What programs are you running when this happens? Have you checked for updated driver software from the various manufacturers of your peripheral devices?

    As odd as it might sound, step 1 disconnect the hub and reboot. Hubs can cause problems. Step 2, if that doesn't work, create a new user account and log into that account to see if the problem follows that account.

    You have no idea a) how many times I've seen this solve Mac & PC crashing problems and b) how many times I've been told I'm an idiot for suggesting it

    had the same problems for three weeks since upgrading my imacs Leopard to Snow Leopard, Constant crashing and random black screens. I tried resetting everything recommended, using disk utility to fix permissions and even a fresh install, but it did not make any difference.

    Four days ago i started my imac in I think it's called Super User or Single User Mode

    Turn off your mac
    Hold Down "Shift + S"
    then press the power button and hold "Shift + S" until you are prompted to enter your password

    Safari, Autodesk Maya used to crash every five minutes and now i can use them all day without a problem, I think the problem is to do with permissions that disk utility cannot fix.

    I have been having similar problems since upgrading my iMac last week.

    I also have a USB hub and I would be happy to disconnect it to see if it solves the problems...

    But what do I do with all my USB devices and only a couple of available ports on my iMac?
