Do you have a USB keyboard?
I have a laptop which was making similar noises to those you describe and messages about device drivers often appeared.
As the laptop is more or less welded to the desk I have used an external keyboard for some time.
The cable between the keyboard and the laptop had almost worn through where it had become twisted.
When moved, contact was made or broken as the core(s) touched or separated and the 'badunk/badump' noise was issued forth.
