Just finished a new build, z790 ProArt - Windows 10 install, installed all listed drivers and ran windows update. Even after all of this I still have a number of missing devices:
4 listed as just PCI Device, RAID Controller, SM BUS Controller, Universal Serial Bus (USB) Controller, unknown Device
Not really sure whats left to do, again I have tired all the drives listed on the support page. Any help would be great.
I had the same issue with Windows 11 same Asus ProArt Z790-CREATOR WiFi board .
Then I found this information and it helped a bunch. https://www.intel.com/content/www/us/en/download/19347/chipset-inf-utility.html
I am having the same issue, but I think I may know what it is for you BaronBlake. You must install Armoury Crate. From my recollection, it will see those missing drivers and install them. I hate software like Armoury Crate because it adds needless junk to your computer, so once I get the drivers I will uninstall the Armoury Crate software. If you are doing gaming and more personal things you might want to keep it because will keep drivers up to date. I hope this helps you.
I use Armoury Crate for the same reason. It makes a fresh Windows install go smoothly and saves a lot of time. After that, if you want the latest drivers get them from MoKiChU's threads. You can then use the Armoury Crate uninstaller if you don't want to use it any more, but I like it personally and it causes me no issues at all.
If your IO drivers package is like mine, try running the install.bat file instead of asussetup .exe - from memory I think it's a silent install, so the drivers might only show as updated after a reboot. If not, you could also try running both files as admin. The other thing that might help is to go to Device Manager, look in system devices and try updating the drivers manually for the GPIO controller. Click on update drivers and then browse to the downloaded drivers folder. Not certain if this will help, but worth a try.
