How do I install drivers for those didn't get installed automatically?

I go to the computer's official driver website to get some drivers.

Extract All of them into one folder named "driversFolder" maybe.

Then in "Device Manager", click on the device not installed,

click update driver,

click Browse my computer for drivers,

Enter the path as "C:/......./driversFolder", check Include subfolders

        click Next.

This way, I got all my devices installed.

Good luck
