20 Most Recent Gigabyte GA-945GCMX-S2 Motherboard Questions & Answers

Assuming everything is plugged in correctly and supplied with power then you probably need to re-install the audio chipset drivers. This can be done from the Installation CD that came with the motherboard, or if you do not have this go to the following web page:
(you may need to copy & paste the link to your internet browser address bar) choose your OS from the dropdown box, choose the appropriate audio driver, download and install it.

At first I thought your screen went black during the start up process. After seeing the bios screen. In which case I would've said it was a bios setting for the display. Then I realized that I think you mean that their is no display at all. When you push the power button. Only the monitor led light. So, it may be a problem with your RAM stick/s. You should make sure that they are properly seated in the mother board. If they are new, make sure they are compatible with that motherboard. If you can you should swap them out with known good ram sticks. You could also try installing a video card and see if you can get display to work through that one. Make sure your main power supply wire connector is pushed in all the way. Swap the power supply with a known good one if you can. If still can't get it to work you may want to take the motherboard out and inspect it for burns, cracks, and anything that doesn't look right. Maybe contact the manufacturer of the motherboard and ask them what you can check. hope this helps.

It's easy to install the wrong drivers. Many audio chips have similar names it doesn't mean that it belongs. Go to the website of the maker of your motherboard and make sure to download the right one for the right operating system and 64 bit or 32 bit version etc. Use an app like Everest to check the sound chip to see what it is.
