Prime x670P Wifi Broken UEFI UI

[cbardin]

I have an Asus Prime x670p WiFi with an AMD 7950X. I dual boot mainly Arch Linux and occasionally Windows 11. Every now and then after I reboot or shut down from Windows, when I try to boot again, the EFI partitions are corrupted and my UEFI UI is broken (See image). It has happened on multiple BIOS firmware versions and I try to keep the motherboard up to date. It seems to happen every now and then when I shutdown or reboot the computer from Windows. Then if I try to boot Linux, it just backs out and I somehow get a BSOD 0xC0000428: Can't verify Digital signature. I get this message if I try to boot Windows instead. It also shows this message if I try to boot from a Windows Media Creation tool USB. As well, archiso USB will fail to load Linux kernel modules. My entire computer seems to be bricked (accompanied by broken UI) until I reset the CMOS on the motherboard. Then things go back to normal with Windows, but I have to boot archiso and reinstall GRUB to boot Linux again.

I really cannot pinpoint what is causing this to happen because it only happens every few weeks or so. I see how an SSD or CPU issue can lead to corrupted booting partitions. But since the UEFI UI breaks somehow, I think it may be an issue with the motherboard. And I really cannot understand why it won't let me boot USB OS installers when in this 'broken' mode. It's very hard to find any information about it. I have ordered an MSI motherboard to test out other options. But I just want to see if any consumers or devs have seen this broken UEFI UI because it is very frustrating having my entire computer and multiple OSs bricked

Hello @cbardin 

Thank you for reaching out to us and sorry for the delayed reply.
Based on the situation you described, it is likely that the issue is related to the system drive (e.g., EFI partition corruption or Bootloader failure).
We recommend removing all SSDs, HDDs, or external storage devices to check if the system can enter the BIOS without issues, and then try installing a new system drive to see if the system can boot correctly. If necessary, please attempt to format the old drives.
Additionally, since the PRIME X670-P WIFI Tech Specs page indicates that it supports Windows OS, we suggest testing the issue with only Windows OS installed.

Meanwhile, regarding the 0xC0000428: Can't verify Digital signature BSOD error, we recommend that you refer to possible related instructions: Error 0xc0000428 (the digital signature of this file couldn't be verified) with no listed file

Thank you.
