As far as the additional "optional drivers" in Windows update. There are roughly 75 available. All begin with Intel. There are three that just say "Intel - System". Is this what I need? The most recent is from 2017.
"Intel - System" are chipset drivers, install most recent one. (It's newer than what MSI site gives)
Other intel related drivers may help but I don't know what they are, try only recent ones if none of the "Intel - System" drivers work, one by one and reboot for each install until one of them hopefully does something.

I think you can uninstall specific driver updates (ex. before trying older one) in:
Windows updates -> View updates history -> Uninstall updates
