Custom built PC turns on, but no display at all

So basically, after finishing building a PC, I turned it on. The PC itself turned on, but nothing displayed on the monitor at all. I had the OS USB plugged in as well but still nothing.

Try re-seating the memory and GPU, make sure your aux motherboard power and GPU power are plugged in tight, if it still does not work assemble the pc outside the case and see if the problem persists.
