Me and my buddy were working on his new PC and we left it turned on on its side to go watch a video of what to do next (it was booting up fine but we couldn't get a bios or anything) then we smell burning plastic, we turned around and the thing was smoking from the top near the power button. We cut the power supply off unplugged it and took it outside, it stopped smoking somewhere along the way. Now it smells like burnt plastic and we took most everything apart looking for the problem. Any ideas? We are taking it to a specialist tomorrow but info would be great, we couldnt find anything wrong.
