I just purchased the components to build a new gaming pc, and am running into a problem. I have installed my mobo (asus p8z77-v deluxe), my cpu (i5-3570k), my cpu cooler (hyper 212 evo), my ram (8gb corsair vengeance), my gpu (gigabyte gtx 670), and my power supply (corsair hx750). I plugged these in to do a test boot, the mother board lights up and the fans turn on, but then it shuts off immediately (the power supply makes a click noise). It tries to start up again, but the same problem occurs: the lights come on, but it clicks off even before the post. What could be wrong? I tried it without the video card, and individual ram sticks, but the problem persists.

Please help me!
