I just built a new computer and my motherboard keeps crashing. If i do not play a game, it runs perfect. It crashes about a couple of hours into the game. About 1/4 of the time when i start the computer, it seems like it starts but nothing pulls up on the screen, the keyboard and the mouse do not light up. It seems like the OS is bootings but nothing else is working. Also sometimes when I alt tab it crashes my computer and I get a blue screen of death. Is something not compatible?

Intel Core i5 4690k
Gigabyte G1.Sniper Z97
2x 4gb pny 1600 memeory
asus gtx 660 videocard
kingston v300 128gb boot drive
corsair cx750m psu

I am planning to buy a new ssd and a video card soon, but have no idea whats going on with my computer right now and would like to fix the crashing problem first.

nothing shows on the screen so I can not really tell if the machine boots. The screens stay off and the keyboard and mouse do not turn on, but I can not click the power button once and turn the computer off. I actually have to hold the power button down as if the OS booted.
