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

>mobo doesn't have any videocard/graphics card slots aside from the PCI ones [none of which are in use, btw; should they be?].

Actually, this board has one PCI-E x16 slot, so you're definitely set for graphics upgrades when you have the money- if you like games at all, you'll want the upgrade.  As it is, you should be fine with the onboard for now.

I'm not actually sure how long is really needed for the short...I usually leave it for a few minutes and it's fine.  A solid LED usually "Oh hey!  This thing is on!" (or "Oh hey, I have power!" if it's an LED on the board itself) so don't bother using that as any sort of metric for anything.  Here, let me ask this- does the machine post?  If it does, does that display on the connected monitor?
