Can I ask how you updated? If from drivers you downloaded from the motherboard site that could be an issue. It's not always perfectly clear what drivers are for what when motherboards have several revisions. I nearly always use my motherboard disc even though the site might have new stuff. If the old works fine why update. Also if the drivers MS installs during initial installation work, then leave it be and you should be good to go. And finally never, and I mean never, use drivers offered on the MS update site, I have had problems with them every time so I usually created a backup before I tried.
