Monitor not working

I just recieved a replacement motherboard and hooked everything up and it seems like everything is working except for the fact that the monitor is telling me that there is no signal coming from my computer. The cpu fan and the video card fan are both working as are all of the lights that are supposed to be there. I can turn the computer off and on by the power button and even reset it. However I can not get it to display on the monitor. I have double checked the cable that goes from the monitor to the video card and it is snugly fitted. Please Help!

May seem like an odd suggestion, but I saw this error in another post. Where have you plugged in the monitor cable? It should be into the socket on the video card, and NOT into the socket on the mobo's rear panel of connectors.

Next thought: maybe the video card is not seated properly and not working. Remove it and re-seat carefully to see if that helps.

If these don't work AND if your new mobo has video on board, try removing the video card completely and running only from the on-board video. If that does work, you'll have some ideas where to go next. For example, you could try (while using on-board video you can see) going into the BIOS and disabling the on-board video and telling it to use the video card. (By the way, I've seen a system recently that had separate choices in BIOS for a video card in a regular PCI slot or in the PCIe x16 slot.) Then you shut down, re-install the video card, and try that. Only problem here is that, if that still leaves you with a blank screen, you will have to go back to on-board video and, in making that change, may have to reset the BIOS in order to let it use the on-board system again. You do that by shutting down and completely removing power, then remove the mobo quarter-sized disk battery, short out the BIOS Reset pins for a few seconds, replace the battery and power up again. If you do this, you will have to re-adjust anything in the BIOS that you had customized before.
