Tom's hardware has also repaired someone's DX 12 this way but should have run DISM before running sfc /scannow.

I would judge that, as you are already being asked to re-install DX12, that you should do the same. I always do these checks, even on brand new installations, as it can correct any faults - before - problems arise. I have also recently acquired a new MEDION Erazer computer and after the initial factory installation was complete I checked it using the DISM commands followed by running sfc /scannow which had to replace some corrupt and missing files. Did it come fully installed, or did you have to initiate the factory install?
