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

Yesterday I changed my Ryzen 7 1700X to a new Ryzen 9 3950X. It successfully booted to BIOS, booted to GRUB and successfully loaded Linux (Ubuntu 18.04 LTS) without any problem.

However, when I tried to boot into Windows 10 (1909), I saw the spinning dots with the WIndows logo, but after that the screen went black. So I tried to hard reset my PC but it didn't accept anything. The only way to shutdown my PC was to turn off the PSU(!).

Booting from the installation USB drive containing Windows 10 1909 showed exactly the same problem.


My system setup:

Ryzen 9 3950X

GTX 1070

Asrock X370 Professional Gaming with the latest BIOS (P6.20)

2 SATA SSDs (for minimal setup)

Corsair H115i AIO

750W PSU

64GB (16x4) DDR4-3200


I don't think my new CPU is defective but I just can't figure out what is the problem.


Thanks in advance!
