Custom Built Computer Issue; Not showing display. Help?

I recently built my own computer, I have attempted to at least have the BIOS display, but with no luck, no monitor I use will prompt a display. I had this problem about a month ago when I attempted to build the computer originally, and I sent back and had my motherboard repaired, so it is at the least not the motherboard that is the problem. All of the CASE LED's work, all of the fans work, and the light on the motherboard is green.

What can I do?

Here are the Specs;

Here is kind of a checklist/trouble shooting guide for no video or post problems with new builds that I found when I was having problems with mine.

The i5-760 doesn't have integrated graphics, so unless you get yourself a graphics card and you attach your monitor to it you'll never see the bios.
