Z370 Fatal1ty gaming i7 problem

Hello,
i have the following problem.
When I turn off the PC, all the peripherals are not turned off, some remain active and I have to manually unplug the power supply, then everything goes off.
Then when I turn the power supply back on, the peripheral devices do not switch on again until the next reboot (via button), and this is ok.
In practice, the system leaves power to the fans (which continue to run), to the pump (Aio) of the processor and to the graphics card; it regularly switches off the mouse, the keyboard, the various LEDs, and the hard disks.
Of course I tried to enable or disable the various energy savings in both windows and Uefi, but nothing has changed.
I have the latest version of the Uefi 1.20
Do you have any solution that I can try?
Thank you

My system
Asrock Z370 Fatal1ty Gaming i7
8700k
Aio Corsair H115i
32gb gskill trident z rgb 3600mhz
Msi 1080ti x trio
Windows 10 64bit

It worked right when I transferred over my a clone of my hard drive from the old computer. I keep reinstalling Windows and after a few boots it begins to crap out. Task Manager also seems to stall whenever I close it. And the wireless has yet to work.

Fortunately, everything works well for me. I only have this problem.
We hope that some of the Asrock Gurus will help us.

Same issue here and yet to hear from ASROCK on email sent.
