If you’ve tried everything else and still have those annoying beeps emitting from the internal computer speaker you can ensure that it is turned off as follows:

  • RMB on the My Computer icon, and select Manage
  • Click on the “Device Manager”
  • From the “View” menu item select “Show hidden devices”
  • Expand the section Non-Plug and Play Drivers
  • Double-Click “Beep”
  • Select “Do not use this device” in the Device Usage and OK out of all

You may then need to reboot the machine
