Thank you for the screenshot, there is nothing wrong with your hardware.
DirectX 12 is fully backwards compatible to DirectX 11, so there is no need to be installing DirectX 11.
The best first option will be to completely remove the current graphics card device driver using the widely available free DDU utility, then restart your PC and go to the support page for your PC on the manufacturer's website to download and install their recommended version of the graphics card device driver.
A slightly older version of that driver is more stable than the latest version.
