First PC, Not Working. What's The Problem?

I built my first PC and (I made a topic on this yesterday) it won't boot up completely. The power supply (CX600M) turns on, then turns off, then turns on again. This happens over and over. First, we thought the power supply was bad, so we got another one, but that still didn't fix the problem. The monitor isn't getting a signal when plugged up to the computer, and the LED on the power button turns off, then on, then off again, just like the power supply. And everything was plugged into a surge protector. And we checked the voltage and that was right as well. What's the problem? We check all the cables, reseated the RAM, and changed the power supply. What's the problem? Do I need a new motherboard? Because when we jump start the power supply without plugging it into the mobo, the fan stays on.

Check the header cables are connected to the motherboard correctly, try one stick of ram, remove the GPU and see if it boots

Did you make sure you have the front panel headers wired correctly?
Did you try jumping the motherboard its self? 

 

Yes, we have redone the front panel headers so many times. How do you jump a mobo?

We checked all the cables, and we haven't put the GPU in at all. I'll try the one stick of ram

Yeah, we made sure to do that. I think it's the motherboard.
