My name is ***** ***** i would like to answer your question.
The buzzing sound from engine room when engine should be cranking- it points to the starter not engaging fully.
One possibility is that there is a poor ground connection between engine and the body. So try to jump start the car, with charger's negative cable connected to the engine.
If this does not help, knocking on the starter might revive it for some time.
The final solution is to rebuild or replace the starter.
