New Board and Keyboard problem

[ShadowStriker]

So i have a problem, i have a new motherboard(1150) and since i have it(3 days) i have a problem.I played a game fine but when i quit the screen was black and my keyboard locked, no alt ctrl del no nothing, i had to restart my pc.On a second game the screen was black after i opened it, no sound and the keyboard locked again.What the heck is this?I really don't know, first time i encounter this problem.
