When I say it woke itself up, i mean it. Not that there has to be ghosts in there.
How it happens is that one moment it will be asleep, the front panel light blinking as usual, and the next the light will stay on and my comp will post, my cpu fan will start running like it usually does when a computer is turned on/awakened from sleep state.
to loonaim: I went to the windows power options advanced settings, and i found an option for a sleep timer, which was enabled. I disabled it, and hopefully that does the trick. Unfortunately I don't have the time to test right now.
