Unsolved Big, loud noise when Recalbox boots on PC

[vale075]

When I start recalbox 4.1 on my PC, after some time during the booting process, it start to make a really loud and painfull sound.
I dont think it comes from the fans...
The sound starts when the "Starting lirc : OK" appears.

Here is a video of the console

Thank you all in advance !
