Im updating my computer since my motherboard fried out and I have a problem. Bought a new Asus M5A97 R2.0 board. Hooked everything up, but during my bios menu My computer will just...shut itself off. Im running and AMD phenom II cpu. I noticed that the temp rises awfully fast up to about 170° before this auto shut off. I have three case fans. Why is this happening!?
