Beeping?

I don't about you other guys, but my PB starts to beep at the most awkward times. Like it isn't a whining or anything, it just beeps. It sounds like the beeping on a "PC" when a key on the keyboard is held too long; except it's more subtle. Wondering if you guys have ever heard a beeping in on ur books, am i just unique or unlucky?

two beep wonder

I get a strange two short beep sound when starting up my G4. I don't know why, and it's a little worrying, but nothing seems really wrong. Any one else had the same probs?

do this happen when the volume is turned off and something on the computer makes a noise ?
mine makes a lil glitch noise when something is making a noise on the computer but the volume is turned off..i think all it is, is just a little noise leakage coming threw...
does that sound about right ?
