Open soundmixer by double-clicking the speaker icon in systray.
See if there is any slider marked as PC-Speaker.
Turn it down in order to reduce the annoying sound.
If the PC-Speaker slider is not present, choose "Options", "Properties",
make a check on PC-Speaker (or whatever it is called) and accept.
You sould be now able to control its volume.
Not sure whether this applies or not to your notebook but it won't hurt
