At the beginning i installed win 10 pro and did all the tweaking.

i start testing the system with 6 / 3 screens and after restart when the watchout was open the windows freeze after bios.

i try to update all the drivers and last updates foe windows but the same results.

i try to install windows 7 and the same problem.
