re-install everything take it out and then put it again mybe there something is loose

first put only power,cpu,gpu,and ram then put hdd and cd-dvd with that you make sure there is any power problem

take out everything, make sure that the risers/standoffs are installed and install the mobo and the cpu w/ fan. make sure that the mobo makes long beeps.

Sorry for the question, but is the power supply switch on? If it is, I would check all connectors, Ram, standoffs, and video card.

Most new motherboard installs require the CMOS to be reset, before first bootup. If no action is caused by the on/off switch(lights/fans turning/beeps/etc) it could be missing spacers, missing fiber washers, or maybe just simply the power switch leads are connected wrong.
