[SOLVED] When PC is powered on GPU starts up for a second and then stops.

I recently built a new pc but upon completion only the GPU seemed to get power as it was the only component to light up. The motherboard led will not turn on. All power cables are plugged into the motherboard except for the cpu pwr 2. When I press the power button the gpu starts up for approx. 1 sec then immediately turns off. I am wondering if one of my components is shot, or maybe I installed something incorrectly.

I was not aware gigabyte even branded some PSU's which means they are probably low quality. I would immediately suspect the PSU. Look into getting a Seasonic, Corsair, or EVGA branded PSU.
