So about a month ago I built a gaming pc and it was working fine. I brought the desktop over to a buddys house and took the side panel off to show him a couple things on building his new computer. I unplugged a few things in mine but I made sure they were all plugged back in. Now, when I hit the power button, the fans go and everything lights up for about .5 of a second then it shuts down.. All my components worked fine 2 days ago.
