Obviously something is wrong.

Build the minimum configuration (PSU, motherboard, one stick of RAM, graphic card if no onboard graphics) outside the case (om cardboard, for example). If that works, you know that hardware is fine. Then build the same inside the case, and continue from that.
If the minimum configuration doesn't work (and connected correctly) one of the components is defective. Return that.
