After updating my Dell 7567 to the latest recommended version (1.11.0) my notebook started to have problems, inconsistencies.

1- video error (artifacts on the screen)
2- audio error (sound with noise during the game)
3- freezes on windows (using original and updated windows 10 pro)

There is no channel to request support from Dell after an expired warranty, we are at the mercy of whatever you want.
They launch a defective BIOS, it does not report that there was an error or its probable solution.

Attached are two images of what happened (how sad it is to update a badly programmed BIOS)
