Can't Figure Out the Issue...

I just bought this motherboard:

http://www.newegg.com/Product/Product.aspx?Item=N82E16813130542

Now I'm barely in the budding stages of hardware knowledge proficiency but according to the specs, particularly this part:

'Onboard Video
Onboard Video Chipset VIA Chrome9'

I assumed that meant I can operate full and well without having a videocard installed. Makes sense to me, seeing as the mobo doesn't have any videocard/graphics card slots aside from the PCI ones [none of which are in use, btw; should they be?].

So assuming all else is well, what reason[s] would there be for my connected monitor not receiving a signal when I turn on my comp?

FYI:

Motherboard = new
CPU = new
RAM = new
Power Supply = new
The monitor itself works fine, tested it on another computer.
PCI slots are empty; dunno if that's a problem.
And yes, all parts mentioned are compatible with my setup, as I've made absolute sure to read and choose all specs carefully

Check the connection. (Well I just had to say it.)
Also I would try and reset your bios just in case for some reason onboard video is disabled, the directions should be in the motherboard manual.
You may also just have a bad motherboard, and you will end up RMAing it.
