If you have power after recharging the battery (turn on lights) , If lights come on before turning the engine, and you still have no power, It sounds like your starter. You may have to take it out and take it to a auto parts store and have them check it.

As the engine revolutions increase, so does the noise from the engine as it is working harder as opposed to being still idling. Also, could be a leak in your exhaust system that could be the cause of the additional noise.
