The only drivers you will need from Intel are the chipset and LAN driver. You will have to get your video driver and audio driver from whatever manufacturer manufactured your video and audio card.
You dn't have to install the Serial ATA QFE Update at the top of the page since it is included in Windows. Install the chipset driver 1st, then your other drivers.
