Missing PCI encryption and decryption drivers for the ASRock X470 Taichi model
Missing PCI encryption and decryption drivers for the ASRock X470 Taichi model
You're missing drivers for your 3900X and X470 Taichi. You've already downloaded them from the ASRock support site, but they're still missing. Consider checking official ASRock channels or forums for updates.
I examine unknown devices by checking their properties to identify the vendor and hardware IDs, then look them up to determine the exact model and possibly locate a source. As a rough estimate, you could also try installing the newest chipset driver from AMD to see if it resolves the issue. It wouldn't hurt at all.
I haven't checked yet. Could you confirm if you have a download available?
