I have a problem with some drivers of the ryzen chipset, showed me an error of certificates not found and for that reason I do not install, in device manager tells me "Windows cannot verify the digital signature of the drivers required for this device". These are the drivers that do not start "AMD PSP 3.0, AMD PCI, AMD PCI, universal bus controller.

Now how do I install manually?
