I can't stand 'beep','bling','da-da-da-dunt' while I am working at my computer. Maybe my musical background, but I much prefer silence.
But when I turn sounds to 'Off' in my profile (XP) I now am getting an annoying BEEP every time I get email from Outlook and so on. This one is coming from the actual machine.
So here's how to kill that useless BEEP:
My Computer/Hardware/Device Manager
Go to 'View' and select 'Show Hidden Devices' if it isn't already.
Now in your list you should see 'Non-Plug and Play Drivers'.
Find 'Beep' in the list, right-click and disable.
Now no more silly sounds.
