I built it a couple months back and I love it except for one thing: it will turn itself on at random. Today I shut it down and the fans didn't even stop spinning before it booted up again. I shut it down again and it took about a minute before firing up. this doesn't always happen, but it's bad enough that I really need to switch the power supply off in order to ensure it doesn't come on. It doesn't reboot by itself randomly or anything else noticably weird. The power supply was in a different computer before this one in the same outlet and everything so I'm thinking that's not the lone culprit. Anyone have any ideas on this one?
