Rather doing a driver hunt which can take hours http://download.cnet.com/slimdrivers-free/3000-18513_4-75279940.html Windows XP/Vista/7/8
it might take some time being a freeware driver solution Note: it will find all of your outdated drivers
This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.

Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.

Hope this helps.
