Off screen/comp

When I launch the game, and as soon as I appear, the PC just shuts down, or rather off Monique, but the fans are spinning, nor che did not respond(ctrl-alt-del) have to off and on again(hold button 3 seconds), the whole Google crawled all forums, nothing helped, it's definitely not overheating and does not load percents on 100%.
in the center of the bear as you do not want, and that will tear off so that you can buy R7 370)))
