Was playing league then after 1st game keyboard and mouse stopped working and insufficient power window kept popping up, couldn’t get anything to work on it so I shut it down and now it won’t turn back on. Power supply was a 650w and I upgraded to a 850w just incase thinking it may be the power supply but still no dice. Any suggestions on possible issues or solutions. The lights turned on for like a half second when i tried to turn it on but literally not even the new power supply is running.
