Need help with a strange computer issue I keep getting. Any input will be greatly appreciated. When I'm playing a game it will randomly turn off by itself. When I try to reboot it, for some reason the monitor isn't able to detect a signal and just goes to sleep. The computer seems to boot up normally while the monitor stays off. It's not an overheating issue as I have been monitoring the temps and the hottest it got was low 70s (degrees). I usually have to leave it off for a while and come back for it to work normally again. I got it working right after it shut down by turning it on without monitor cable plugged into computer and then turning it off and replugging it. But I think that was random luck. Anyone know what it could be I'm pretty confused.
