I’m thinking it’s a problem with the driver, though its interesting that the network driver didn’t show up.
Depending on your board, say if its an ASUS:
Download Center | Official Support | ASUS UK You can get the download link from the boards manufacturer. I’m guessing either the driver you downloaded is no good, or it doesnt work with your components.
What motherboard do you have?
Just checking, you did try to use device manager to manually find the driver you put onto the computer? Not just expect it to find it from the usb?
