How to determine the source of squeaking and creaking in a laptop?

Question

Iron

The laptop began to creak and squeak, the sound comes from the radiator grille at the end. Beeps when you press the buttons, touchbar, screen (touch), under load, in the process of turning it off / on. If you go into the bios before booting, the crack stops.
I didn't install any special software. What could be the problem? I sin on some recent update of Windows.
OS: Win10 SL
Notebook ASUS ux370ua
