Did you try a different cable to connect the graphics card to the monitor? Try DVI or VGA if you can.
Are you sure it actually is posting? There may be lights and spinning fans inside your case, but the computer still didn't properly POST.

I'd look at Tom's guide for building a new PC, and make sure you have all the checkpoints. Power cables, 1 stick of RAM, no peripheral hardware, no extra USB devices (Besides keyboard), PSU switch, single HDD, and so on. There are hundreds of posts about "New build won't boot". It could be dozen different things at this point.

There is a link to a troubleshooting checklist in my signature. The checklist was created for this type of problem. If you perform all the steps in the checklist it should help you narrow down what's causing the problem.
