I'm going to download all my drivers except gpu onto a usb before building my pc and installing them that way. I have the asrock z97 extreme 4 and my os is 8.1 64 bit, when I chose these options for the drivers, the website cam up with a long list of downlaods, under drivers and also utilities? Do I need to download all of of these? Also could someone tell me all of the parts I need to download drivers for?
