thks for the answer Spooky2th
well, no problem with the driver i think
when i connect an external screen i can see Windows is started ok each time.
and when my laptop screen is black, i can hear... windows is started ok.
it s just a bad electric miss-connexion at the bad moment (on bios scan for screen, i think)
😉
but i ll think about your proposal
