Why won't my newly built PC output video?

I've built this computer. When I power it on, all of the fans work, the lights come on, the DVD drive works, and it had no beeps. With that being said, there's not output video. I've tried it on two different monitors with HDMI and VGA connection. Can someone please take a look to see if I 'am missing anything? The only thing I can think of being the problem is maybe the hard drive, being that a friend gave me the drive as he had it lying around. Any feedback would be greatly appreciated.
