I have had this pc for the better part of 6 months with 0 problems, running like a dream. Recently after a long night of gaming my pc shut itself off mid game and emitted a burning smell, it was also extremely hot. After doing some looking around on the internet most signs seemed to point toward the PSU being the problem. I bought a new PSU and swapped out the old one but it the same problem has occurred. It turns on for a split second (fans spin lights turn on) and then off again instantly, also to get it to do this have to unplug and replug the power chord and flick the switch on the psu. Not sure where to go from here.
