My PC worked fine a couple days ago. Now, whenever I turn it on the monitor doesn't display anything, the fans flicker and spin at a lower rpm, my video card has its "over temp protection" light on.

I don't know what's wrong. My HDD light is on but its red instead of blue. Could the problem be my mobo? I just built this PC a few months ago.

Spec:
ASUS M4A79XTD EVO
Phenom II X4 955 BE
Corsair 650TX
Samsung Spinpoint F3 1TB
Sapphire VaporX 4870
G.Skill Ripjaws 2x2GB DDR3 1600

Need help/advice/suggestions. Everything is stock, nothing has been OC'd.
