Please help
 
Does your MOBO have onboard graphics, and are you using a graphics card as well? if so, plug the display into the motherboards graphic ports, and then go into the BIOS and tell it to not use the onboard graphics as the primary display.
Or vice versa, if you it plugged into the mobo and not the GFX card.

If that doesnt work, post your full system specs and we'll go from there.

likely, your mobo doesnt have an onboard speaker, and unless your case came with one, you won't hear any beep codes. You can buy them though, from a local electronic store for pretty cheap (like $2 maybe) and then hook it up to the motherboard and turn it on and see if it beeps at you, then you can figure out what the beep codes mean. Generally if it's not a single short beep, there is something wrong.
