I am trying to install my new 750w PSU to an Asus M51AC with a GTX 770 DCU2 OC. When I turn on the computer, some of the fans start for just a second, the computer makes a loud, deep, booting sound, and then there is a brief whirring-zapping kinda noise I've never heard before. All this happens consistently. The green led on the motherboard which is normally lit is not currently. I believe I have everything connected properly, but I'm not sure what I'm missing here. Thanks very much for any help!
