Generally, there's a way to install the latest BIOS from the web in the UEFI; also, reset button? If that doesn't work use safe boot and see if that helps. It sounds like this is a fresh install, if it is, try reinstalling; if not, use remote desktop from your phone or another device to install drivers. You can also just leave it booted into Windows (without logging in) and see if windows auto-installs drivers (not sure if that works without being logged in, but it's worth a shot).
