Okay, I'm most likely in the wrong forum, but I could not find for the life of me the PowerPC G5 area, so I came to the next closest thing.

I have a Power PC G5 with 2 GHz processor and 2 GB DDR SDRAM. For some unknown reason to me it will restart on its own. I can turn it off, watch it power down completely, and the next morning it will be at the screen waiting for me to enter my password. As well, if I leave it on (even with a program running) for an extensive period of time while I'm away from the computer, the computer will restart. I don't have it set to sleep or anything, so I'm wondering if you guys can give me any tips or help or at least give me a shove in the right direction on the forums.

PowerBook G4, Mac OS X (10.4.11), 1 GB Ram 80 GB HD 1.5 GHz

    A USB device may be culprit. Disconnect all USB devices, including your kbd & mouse. Now see if it restarts. If not, reconnect the USB devices one at a time & shutdown. I believe you'll find which one.

    Edit - Another thought. Check this first. Open the Energy Saver preference window & click on Options. Is Restart after Power Failure checked? You may be having a brief power interruption.

    Well, I checked both the USB connected devises and the "restart after power failure" option (which was not clicked).

    Neither were the culprit. My computer is still restarting on its own. Any other suggestions? Or just take it to the geeks =)
