if you have SATA drives, you will need drivers for the hard disks. Other than that, you will need drivers for printers, scanners, cameras etc.... many drivers can be found during a windows update, but that is not guaranteed.
sound drivers are provided by your motherboard manufacturer or if you have a dedicated sound card, (rare these days), by the sound card maker.
You really need to post specifics about your system. No one here has a crystal ball.
