Take them one-by one.
To update the nVidia drivers, use the widget at the bottom of this post.
Don't worry about pcouffin.sys, spldr.sys, gearaspiwdm.sys, or amdxata.sys. They are Windows drivers, and there is no way/need to update them.
You no longer need to worry about the Semantec drivers, as you uninstalled Semantec earlier.
The only other one you need to worry about is RTKVAC.SYS, which is your Realtek AC '97 driver. Look on your computer manufacturer's site for an update to your audio drivers.
