Good question. If you're sure all of the basic tests have been performed (monitor brightness/power/etc.; cable correctly connected to computer, etc.) then you may have a bad motherboard.
If it's a brand new (never used) mobo, then it should come with the on-board video enabled. If this is the case, then perhaps the mobo is bad or the monitor is bad.
If the board is new to you but used, perhaps the on-board video is disabled. To fix this, remove the cmos battery for about 10 seconds then put it back in. This will erase all settings and put them back to their defaults enabling the on-board video.
If all else fails, try putting in an external video card to see if you can get a signal.

Power it all down, Junior, and disconnect and reconnect all your monitor cables.
Added: Sorry Junior, I was only trying to start with the most basic troubleshooting technique. I have never replaced the motherboard so I can't really help you beyond that.
But if you reset the BIOS and got video, then do it again. But what happens after that to make the video go away????
