That is why we recommend you try our Outbyte Driver Updater, an almost entirely automated tool created to find missing drivers, repair broken ones, and update the older ones, all within a few minutes.

Simply launch it, let it scan your PC for problematic drivers, allow it to download and install them, and you’re all set.
