Question PLEASE HELP mobo led lights up but wont turn on.

[LazEring]

PLEASE HELP. I have an x79 motherboard with an i7 3930k. It has 4 sticks 4gb each at 1333 mhz. I know the mem works. When I plug it into power, the green. Led lights up. It hasn't been used in a while so I used the bios flashback feature, and it worked correctly to flash the latest bios. The cooler works. I tried to turn it on, and it didnt do anything. No fan spin or any sign of activity other than the led. I also tried bridging the per and ground pin on the mobo to turn it on, no luck. I thought my problem was the bios, but it went ok, but the pc still wont turn on. ANY HELP WOULD BE IMMENSLY APPRECIATED
