I just bought a ASRock Z77 Extreme4 and I am ready to install the most recent drivers from http://www.asrock.com/MB/download. [...] 4&o=Win764 , but I am confused as to which drivers I need to download. I think I have the USB and Audio drivers, but what chipset drivers and Network Interface card drivers?
Most motherboards have an update manager that will update the boards chipsets and nic card drivers. If you go to install a driver and it's older than the one you have it will tell you. Usually the cd that comes with the motherboard has the drivers that you need and unless you are having problems you don't have to update anything right away. The Z77 chipset is new and there most likely is the newest drivers on the cd.
