ah, your article is awesome! thank you, friend.
I have actually already checked most of those tips, but I was not aware of the command prompt commands. Upon closer look, it seems my windows 8 is set to a "system maintenance" at a certain time, although I don't recall the computer waking at the specified time. it has been random. Anyways, I will start putting my PC back to sleep and monitor the next time it wakes back up, and adjust settings accordingly.
If the culprit is a scheduled task, would it be possible to allow the pc to run said task, but make it promptly go back to sleep when finished?
