Supposedly you can fix this by turning off "sticky keys" . I get the beeps all the time too, and its only since installing XP. You can get to the settings by going to the accessibility options section of the control panel, or by hitting shift 5 times. Go to the general tab and then turn off both notification features. No more beeps. The first time I noticed it was while playing a game, if I held the cursor key down for more than a couple seconds the speaker would beep.
