After completing build everything was good and dandy. Went afk for 20 minutes while downloading some regular stuff. Steam, afterburner, ya know the works. Came back to black screen and mouse not responding. I know usb's work cuz keyboard lights up in all slots. All mobo leds light up and everything. Need help please revive my new build !
