I just recently built a new machine, below are the specs for this machine. The problem I am having is that I'm not getting any video at all. I've replaced the power supply and video card and am still getting a no signal message on the monitor. I know the monitor works because I've hooked it up to my laptop via the VGA connection. Everything else is working just fine as far as I can tell.

Thank you.

Those pins are missing because they are not needed. The missing pins are for a digital signal which is not needed in a VGA converter which only uses an analog signal.

To Jaxmc:

Play around with the RAM. Try one stick at a time and in different slots. It would be ideal if you could drop your RAM in someone else's machine to make sure it works.
