Was the power cord unplugged while removing the battery?
If yes, and still the same, then it would be good to connect an internal speaker to the motherboard.
Start the board with only CPU and CPU fan installed and see if any beeps.
tried i get no sound for ram. my mobo has never had sound on it. when i first built it i missed out ram and it never beeped at me then. i think they got rid of the beeps on new boards
