you should at least grab a copy of your WiFi or Ethernet driver. a lot of the time people are missing that one after a clean install—and you'll need a second PC to acquire it after reinstalling in the case that you do need it.
usually Windows Update is good at getting the other drivers. i personally would grab your WiFi/Ethernet driver, clean install, let Windows Update run its course (keep checking for updates until there are none left), then take a look at Device Manager for anything with a
or anything under the "Unknown devices" category.
