I posted this over at the Apple Support Forums and was told the following is impossible; nonetheless, it occurred. I would appreciate any ideas that anyone here has to explain this:
I only use my iMac at night for a couple of hours. Last night, the screen went black, and the computer turned itself off. While this is obviously an issue, that is not why I am writing.
I went into the Console to see if I could see anything weird about the event I'd just experienced with the crash. Instead, I found a list of activity earlier in the day when the computer was turned OFF and NOT connected to the internet. (I have two computers, both of which connect with ethernet to an airport extreme/dsl modem. I only have one ethernet cable so I move it to the computer that is in use.)
Is it possible that the iMac is "running" processes while it is not on? It is plugged into a power strip, so it is getting juice. However, I was not using this computer at 14:57:39 to 14:58:04. It was not powered up and the only cords going to it were the power cord, as well as a USB keyboard. That's it. Any one have any ideas about how to explain this? Here is the information from the system log:

Looking back through the logs, it seems like this has been going on for awhile. Any assistance and/or explanations GREATLY appreciated. What does this mean? The computer was OFF, and the console system log tells me the above occurred just before 3 pm EDT. I did not turn the computer on until 7 pm last night.
