Unfortunately, new doesn't necessarily = good enough to run XIV. :-(
You could try to boot it up at bare minimum settings:
Go Start Menu --> Square Enix --> FFXIV Config
Under General Options, turn everything all the way down, apply changes / save changes, then try to reboot.
Make sure you are right clicking the XIV icon from desktop and "Run as Administrator"
EDIT: *** don't get too discouraged, my brand new gaming rig couldn't run benchmark either with factory / default settings and drivers, but it absolutely scorches the game after some tweaks ***
