Constant 3 note disconnection beep after Windows re-install

[eco_bach]

After latest Windows update which hung my system I was forced to do a format and reinstall of Windows 10.

After installing using external USB and applying all updates I am getting a constant (every couple seconds) 3 note reconnection tone.

Annoying!

I tried disconnecting ALL external usb devices and dongles. Still same.

Also went into Settings>USB and disabled

'Notify me if there are issues connecting to USB devices'

I am not getting any desktop notifications of any error, just the sound.
After checking the Microsoft site I also tried doing a clean reboot. Same issue.
I've never experienced this before and my PC has worked fine for a couple years. The only thing I've done is a format of my old C drive partition and a clean install of Windows. Possibly hardware related but why after only a software install?

Please help. Driving me crazy!

I believe there should be a log of devices it is finding getting installed/uninstalled/unplugged. HDMI/DP can also do that sound when it connects. It's possible other devices may be doing it that are internal. I'd recommend googling to see if you can find a log file for device connection/disconnection and go from there.

After the most recent update I was getting this occasionally from my DP monitor. Once I unplugged it from the graphics card and plugged it back in it seems to have stopped. It could have been lose to begin with and finally wiggled out enough so it might not have anything to do with the update but you might give it a shot.
