When I switch on my machine, sometimes intead of the startup sound, I only hear "The USB flash drive is not present".

Of course I double check that it's well inserted with the correct sound files on it.

What should I do as it only appends from time to time?

You should check the 5V with a DMM on the white extension connector (5V/GND) , while flipping or bumping, it should be steady and not bellow 4.9V.
If it's not the case,  fix your power board:
