After a week, no reply from Asrock support email about this issue.
I have no choice but to return the mainboard and never buy asrock Again.
Issues can happen, but total lack of support is unacceptable.

Hi, (forgive my bad english) I just assembled a new PC with:

Mainboard: AsRock X299 Killer SLI/AC
CPU: Intel  i7-7800x
SSD: Samsung 950-PRO M.2 
RAM: 32GB Corsair Vengeance DDR4-3000 (4x8gb, running yet at "bios default" 2133 for now)
GPU: Aorus NVidia GTX1080ti GPU.
PSU: EVGA Supernova G3 850w

The SSD already contained an operating system, and the very first time I powered the PC it booted correctly, but when I rebooted the PC for the first time, it no longer booted up.The PC start up, the bios works fine, but it won't load the OS..Then I tried to boot from a USB KEY with Win10 installation, and with Win10 original CD, but when I press F11 to select boot unit, and I select any unit, the screen goes black and don't boot anything.I even tried to update BIOS via "internet flash", it found a FW update (1.20), but when I try to update it, the process fail, with "secure flash check fail!" error.
