The new motherboard is generating a persistent electronic buzzing sound when connected to the monitor.
You've just upgraded your system with a new motherboard, processor, and RAM. The monitor is now producing a low-frequency buzzing sound, which seems to stop when you disconnect the HDMI cables from either the graphics card or the monitor. This could be related to power delivery issues, cable connections, or driver problems. Check the power supply and ensure all connections are secure. Also, verify that your graphics card drivers are up to date.
Earlier I might have mentioned a coil whine issue and thought it wasn’t a big deal. I learned how it functions once more, but recently someone clarified my previous idea was incorrect. The new explanation suggests it could still be related to coil whine, though it implies the monitor’s coil might be gradually deteriorating. This might not affect performance at all.
Click the speaker icon in the system tray, navigate to Sound Settings, select "Sound Control Panel" from the related options, and turn off Nvidia audio devices. Or, check Device Manager for NVIDIA High Definition Audio and the Virtual Audio Device under Sound, Video, and Game controllers. If your monitor isn’t connected to the motherboard, the problem likely isn’t with the board itself unless there’s power leakage through the PCIe slot affecting the speakers. If the monitor has no speakers, the issue probably doesn’t exist. You might also try turning off the monitor’s volume.
I assume you meant to confirm the source isn't the speakers? The nature of sound being analog means things shift when moving from digital to analog, often significantly. If sound appears from a speaker even when it's unpowered, it might be a speaker wire inside the device experiencing crosstalk from another component that activates only when that plug is connected.
