I have a 1950x in a Zenith Extreme motherboard (latest Version 0701 bios), with Windows 10 (Version 10.0.15063 Build 15063). Upon installing the 17.50 NVME Raid drivers, the computer no longer powers down normally. I have very much confirmed this for my case, as I have a backup from right before installing the drivers, and it behaves normally. Also I have tried to go back to this backup a few times and try again with the driver install, and got the same results each time. So whenever I try to shutdown, restart, sleep, or hibernate, the monitors turn off and the machine keeps running forever. This completely breaks hibernate and sleep, and when the computer turns itself on to do updates/backups, it must either remain on, or try and fail to power down until I arrive to manually hold down the power button.
Thanks for the post, please report this to Asus directly so they can test the issue and invesigate.
