You start by unzipping the .zip file content to a folder (usually the folder is created automatically but not always, so when you see the"Extract To" directory prompt choose or create a folder for the destination/location where the unzipped file will reside).
Once the folder is created, use Windows Explorer to browse the contents of the driver folder that was created. You should see a file named "Setup.exe", double click on this file to start the driver install.
Generally the first driver you should install is the Motherboard/chipset driver, followed by the SATA, USB, LAN and other drivers (each of which should be unzipped to there own unique folder)
