So I built this computer recently, and everything was working perfectly after it posted, but then while I was downloading my first game the computer shut off and won’t turn back on. It still has power though, meaning all the fans and the gpu are still on. However when I boot it up there is nothing sent to the display and my keyboard and mouse don’t light up, but there is power to the USB hub that they’re plugged into. I’ve tried replugging in the 20+4 pin and cpu connector and making sure my ram and GPU are in tight, but nothing seems to work. Help?!
