My PC has started making a deep long beep sound when running MSFS2020 it happens randomly. I have all monitoring running and there is absolutely no correlation between the sound and any variance in the heat or voltage of components. The only variance that 'sometimes' occurs is that the CPU & GPU can show 100% use, but not every time. It is not the small internal PC speaker used by the system for BIOS beeps. Nor is it the external speakers (they are off). My only suspects are something to do with the USB, could it be my Alpha Flight Control? Note that although this example is a 3x beep, most of the time it is only 1 long beep.
I have put the sound on this youtube page:
