I was casually browsing the interwebs, when all of a sudden my display goes black, and my computer powers down...When I turn the PC back on, all of the programs I had open (chrome, WMP, Notepad, Windows Messenger) were already open, it didn't do a normal start up or anything. I'm completely confused, I've never even heard of this happening.

More aboutweird thing happened
it randomly went into hibernate? or standby?
check if your computer is set to go sleep after a certain interval of inactivity
it's not, display turns off after 15 minutes, goes into sleep "never"
