| I had a similar problem with my iMac DV freezing. Turned out the iMac was fine but it was the mouse and keyboard that was freezing. It would happen intermittently, sometimes every few months sometimes every few minutes. If I disconnected and reconnected the USB cable the problem would be reset and everything would work well again until the next incident.
I eventually brought it in for service under warranty and they claimed they fixed it. It worked good for a while but started failing again, of course the warranty was expired by then. Unfortunately with the 'fix' CompUSA implemented the it was no longer just the mouse and keyboard freezing, now it was the entire iMac that was freezing. I had to hard reboot using the reset button. Since this screws up OS X (I have to boot off the CD and fix the OS) I just gave up on the iMac which is now collecting dust next to the Win2K PC I borrowed from work.
Good luck,
