Comp won't Boot..

[j3sus]

k so basically i just got done building myself a new comp .. i got a M2n Sli Delux mobo 880 watt PS 9800gt 4 gigs of ram and everything boots up perfect except for the fact that the monitor stays black.. The comp doesnt beep like it should when i start it but everything looks like its runnig fine, the heatsink hdd and everything. Everythingis connect right i done it a 100 times.. Its a lcd montior and it works since i tried it on a diff comp. anyone got any ideas on why it don't boot and the monitor doesn't display anything?

Does the mobo have an internal vid card built in? If so, be sure that is disabled in BIOS.

Also, if you are using Digi as apposed to analog most new monitors require you change the source input. Usually there is a button on the front that allows you to switch from analog to digital.
