update motherboard drivers

clipped from forums.whirlpool.net.au If I want to update my 45-DS3 drivers. Do i have to uninstall old drivers first? Or can i just download and run? Drivers or BIOS? If drivers, then the common thing is to uninstall the old then install new but others are happy to install over the old. Just make sure you set a system restore point before you go ahead.
