freeze when windows 8/10 and csm support enabled

[pasique]

hi,

I would like your opinion with a problem I have with my computer.
the motherboad is a H170 - D3HP and the processor is an intel skylake 6500. In the bios:
when i select windows 8/10 features to windows 8/10 and csm support to disabled i have freeze and error message with amd driver (crimson). maily in game
when i select windows 8/10 features to other os and csm support to enabled everything works.

my graphic card is an rx 480 so it is uefi
I created an UEFI Bootable USB

any idea on why i can't use uefi version instead of bios?

thks for your help

You cant change the bios after you installed windows 10.

You cant change the bios after you installed windows 10.

well, i installed windows with the setting explained here:
Solved Secure Boot and Windows 8 Activation

once i did it, i have freeze randomly.

then I go to bios, set windows 8/10 to other os and csm support to ENABLED

and no more freeze.
