The beeps probably have nothing to do with the POST since you can mute them out.

What have you got running in the background? Open your Activity Monitor application from Utilities and look for something that's running that's causing the beeps. Perhaps a timer program or some such?

Another test you can do: Start the machine in Safe mode and see if the same happens. Press and hold the Shift key as soon as you hear the chime. Safe mode disables startup and background activities.
