In modern PCs, the internal PC speaker is often also connected to the PC's audio solution, so that it allows the PC to play a beep even when there are no external speakers connected to the machine. If your Windows 7 PC runs without speakers connected or with the sound drivers not working or disabled, you might hear an annoying beeping sound for example when a message box notification displays. If you are annoyed by this beep sound, you might be interested in disabling it. Here is how you can do it.
