try first this if it will display bios startup- just install the processor, 1 at a time memory, power supply, make sure the video card has the 6 pin also connected to power your video card

it could also be the wires you plugged into the power button could be done incorrectly. there should be a schematic on the mobo itself or in the manual that tells you how to set it up

find the long bar. plug that into your motherboard in the corresponding spot. find the 4 pin for cpu. do the same. that should get it to boot. if you have a graphics card, plug in the 6 pins accordingly.
