Hi @marichoy 

The sound may be emanating from the power supply if the noise is at the back of the Desktop.

I have no idea why moving the keyboard would stop the annoying sound.

Do you have a wireless keyboard and mouse? Maybe you are hearing some kind of very unusual radio frequency anomaly.

Try different USB ports if you have wireless stuff connected to the PC.

Try wired keyboard and mouse, remove the wireless USB dongle to check for peace and quiet.
