this site has an driver updater program that works great & it is for (free) / all you have to do is join as a memeber (free) install the program & then work thru it and it will get you all the drivers for your system for (free)
this program will scan your system (mobo & added devices) and then search for the drivers
now it will list them as for importance like (chipset , network adapter, video, ect..)it is best to download all that you need and to install them in the order that you download them
for some of the drivers it may be nessary to disconnect from the internet & disable your antivirus so that it will not interfear with the installation process
also have you been to the Microsoft Update site and gotten all your updates ?
here you not only get patches but drivers for your softwares core system !! i recommend doing a custom scan for it will show you updates that are hdden and will stablize your system
you do not have to download all of them but i recommend all of them except for windows media player 11 if you dont want it
