I have a gateway Dx4300. When I turn on the computer I get the Gateway logo, then it gives me a screen that say "no signal RGB". I tested the monitor separately and it works. I purchased a new motherboard and install it and I am still getting the same message. Also, it refuses to shutdown manually with the power bottom. Help!!!!

The video card is connected to the system board. And no I do not hear any beeps when it starts up.
