[QUOTE="MacDude121, post: 1322667, member: 173432"] Your particular model of iMac can accept up to 2GB of ram, so I doubt that that's the problem. I've heard of a similar problem to this that affects iBook G4's, there is a sensor near the optical drive and if it stops working, the system fails to wake from sleep mode forcing a hard reboot of the computer. It may very well be different on the iMac, not entirely sure. You might just want to disable sleep mode by going to System Preferences> Energy Saver> and sliding the sleep time option all the way over to "Never" There's no real problem with not letting your computer sleep, sure it'll draw more power, but just lower the brightness of the screen if you're going out for a while, and shut it off before you go to sleep, and you should be just fine. :) [/QUOTE]
