Hi I am trying to build my first gaming computer, I have installed all hardware but having problems with wiring the motherboard, I tried to hook up all the wires but when I pressed the power button no fans, lights, beeps, or power. I have a Antec 900 case, Asrock z97 fatality killer mobo, consair cx750m power supply, with a intel core-4670k Lga1150 processor. I am at my whits end, been watching videos after videos and still cannot get the computer to power up.
