Had the same cold boot issue under Win 11. Looks like Asus is not ready for prime time, the same as they have not been in the past (my 2nd Asus disaster and will be my last). It works but not as intended, never had a problem with Gigabyte or better yet Apple. Ive been building these systems for 40+ yrs and your documentation on the ThunderboltEX 4 indicates backwards compatability which needs to be delivered without issue. Spending $2K+ on PC it should be expected to work as I went by Asus' recommended ram & CPU. Might need to be an issue for my state attorney general to address with Asus needing to send someone from upper management to Mississippi to answer before a judge as to why. I've taken on AT&T with that method and won so Asus is not going to be an issue. It's the Thunderbolt controller, not the HD Driver. Im a system builder/consultant for Digital Audio Workstations and Asus is about to be a "Do Not Buy" in my world and my customers. SMH!
