What drivers do I install for my new PC?

Hello... the asus web site for your Board... https://www.asus.com/us/Motherboards/Z170-AR/HelpDesk/ driver and tools.
Dl to usb stick...

Your video card... http://www.nvidia.com/Download/index.aspx?lang=en-us

It will Boot first time to your MB video connectors and CPU/GPU... so don't install the Video card until you have changed to the PCIe setting in the BIO's (save&exit) for the video card to be active.

Look in your BIO's screen and see if you have latest version... 2202?

after a Windows version install...

1) Chipset
2) CPU VGA and/or NVidia Video card driver + HD NVidia Video card audio driver. (use custom install)
3) Lan
4) Audio
5) USB3

Look in your Device manager for any RED or Yellow marked items for further needed drivers. B /
 
Hello... It is possible to have different MB revisions/versions... and Different drivers for OS's, But I'm not seeing a option after choosing the OS... Did you use my link? I chose Windows 64 bit and all the listed Drivers categories are there... can you explain further your "version" question? B /
