trying to build a computer, the gpu is getting power the pc its self is not turning on, please help 

 

 

Update:

I fixed the problem, I got a new motherboard but when I was putting it together again I felt like an idiot because I had the CPU power cord flipped the wrong way...

Have you tried taking the GPU out and using the normal display on the MoBo? Are there error lights on the MoBo?

The light on the GPU turns on and there is no lights at all on the motherboard

Are the 8-pin and 24-pin power connectors connected? What specs are we talking about? New or used parts?

I am using this build 

all new parts (besides the gpu) I am using a different power supply and different GPU than in the video

The GPU lights turn on but the case's power button isn't doing anything neither is the LED's on the case. Yes I made sure the pins are correctly in (with the positives and the negatives)
