Loud Screeching Noise on Startup

I have the same issue on my HP ENVY Notebook 17t, running Windows 10 64-bit  (S/N CND6151B0Z, P/N M9X66AV. 


The issue started recently (last few weeks).


I have updated the BIOS, and tried all recommended updates to drivers, etc.


What is the "private" solution to this issue.
