3950X and X370 won't boot Windows (only)

Why would anyone buy a 3950x and not an x570?

Because some of us bought high end over engineered flagship boards with their first gen Ryzen builds and dont have a need for PCIe4.

I just upgraded my 1800x to a 3950x on my Asus Crosshair VI Hero.  Runs like a dream.  I did a fresh install anyway, and actually ran into more problems that way, but it turned out it was microsoft bungling their Windows Updates as per usual.  Wasnt that fault of the hardware at all.  I tried some Patriot Viper DDR4 3600, but it didnt like to play nice with my combo, so im going to stick with my 32GB Flarex CL14@ 3466mhz.

Kudos to AMD for supporting a platform for this long.  The Crosshair VI Hero is/was an amazing board.  Best motherboard ive ever owned.  Had its issues at first until BIOS matured, but from an engineering standpoint, its an amazing piece of work.
