Age of mb would suggest only drivers it might have would be sound or Internet
windows likely has drivers for most of that
Can you download and run Driverview -
http://www.nirsoft.net/utils/driverview.html
All it does is looks at drivers installed; it won't install any (this is intentional as 3rd party driver updaters often get it wrong)
When you run it,
go into view tab and set it to hide all Microsoft drivers, will make list shorter.
Now its up to you, you can look through the drivers and try to find old drivers, or you can take a screenshot from (and including)Driver name to (and including)Creation date.
upload it to an image sharing website and show link here
All I would do is look at driver versions (or dates if you lucky to have any) to see what might have newer versions.
your sound might be running via a rebranded realtek driver, Microsoft may have installed it. Its part of windows after all.
