how do i update the drivers
Are you trying to run a specific driver update or are drivers already installed? You could always run Windows Update which may pull some driver updates (if previous drivers for the hardware are installed).
Otherwise, you would launch Device Manager and highlight the devices in question, select properties and then "Update Driver."
Should you require additional assistance and guidance, Microsoft does have an official Windows 7 Support Forum located here http://tinyurl.com/9fhdl5
. It is supported by product specialists as well as engineers and support teams.
