My asrock fatal1ty x399 is set up with NVME raid, but keeps activating CSM, so I need to manually go into BIOS to switch it off to be able to boot. This happens irregularly.

" rel="nofollow - matesteinforth, not nearly enough information to understand, but I have seen the same thing. One cause was when I updated my AV (Comodo) and I have opened a bug report with them. Another is after hitting the Reset button. I also think that W10 has the capability to activate CMS. Does any of this seem familiar? Enjoy, John.
