I need some help.
When I put my desktop to sleep, and wake it up some time later, the computer has rebooted. I does the same thing when I leave it alone for 15 min, it then goes into the sleep mode. Upon waking it has rebooted itself again. Any ideas how to stop this.

What Mac? What version of OS? What software do you have running when the system is going to sleep?

Is this the latest iMac or a previous generation? I also have a 27" iMac and once about every 2 weeks or so, I do find that the system doesn't want to wake up from sleep, I end up having to power-down by holding the power button and then restart.

I haven't bothered to narrow it down to a specific application or anything that's causing the problem since it happens far enough apart that I could care less..

Usually I have Chrome, Mail, Preview/Adobe Reader, Fraise, iTunes and about half a dozen other utilities running..
