It's hard to diagnose sound problems. Yes disconnecting the speaker will work with no side effects to the puter but I would look for a better fix. Have you tried emailing tech support? That would be another place to start. I would also try muting your mic and other non-needed items in your sound properties. Perhaps one of them is introducing the beeping. I find that unlikely as they shouldn't be outputting sound to the pc speaker though. Is it possible that your computer is overheating and that it is an alarm signal you are hearing? The pc speaker is usually for the bios to output sound to. Not many other programs use it.
