I've set my system to sleep after 1 hour. The annoying thing is that it does this even when I'm listening to music. It does not when I watch movies or anything, but with music it does. It's in programs like Spotify, Winamp, WMP and so on.. Interesting fact: It started recently. I can't say if it was after an update or not. I don't think I've installed anything either. Any help would be greatly appreciated. This is seriously annoying.
