Ok so my build is a msi z77a-g43 mobo with 8gb ram 1tb space no cpu cooler and no gfx card. Yet. But my pc temp is at 35-42 degrees celcius. I play fallout new vegas and minecraft and other hd4000 compatible games. Even when I'm not playing and When I'm doing an essay or something, it crashes. It give me a blue screen saying that my pc has crashed and that it's restarting. I have windows 8. Idk why it does this. This happens at least 10 times a day. Help? Is there anything I'm doing wrong??
