Iíve got a brand new motherboard H270M-ITX/ac.
But I canít boot anymore.
In a first time I try to boot on a usb key, sometime I can but I often canít.
Now I try to reinstall my os but I canít boot on my usb key.
So I try to flash my BIOS with ASRock default tool,
next that it boot only on a screen : ďselect UEFI bootď but my keyboard are not detected anymore so it select automatically my old os partition.
Finaly my screen is not working anymore Ö


Someone have an Idea ? Iím a little bit lost Ö
