Question Ransom PC crash and no more boring automatically

[Reintel244]

So this is a tricky problem. Recently I got a game called mordhau. I've been playing like normal but for some reason I was playing one day and all of the sudden my PC turned completely off. I didn't think much of it cuz I've dealt with heating issues before. But when I turned it on nothing come on the screen. It's on and lights and Dan and everything but nothing on the monitor. So I boot up again and I go into my bios and change the booting to my drive with windows. It's works but the after I turn off it all happens again. So from now on I have to turn on the computer then turn off then turn on again(boots automatically into safe mode) then choose my boot drive. I think it's my PSU but I'm not sure. Can anyone help?

We are not sure either, but you do need to list your computer specs in FULL, monitor and what cable you are using from gpu to monitor
