Yep - that may be the problem. That version has nasty DPC Latency. You won't find a later driver than you've got on Windows Update. Download the 126.96.36.1990 version from the OP of this thread: http://rog.asus.com/forum/showthread...untry=&status=
I can't remember if you need to uninstall your previous version or do anything special for installation, like install from Device Manager by choosing to select the directory where you expanded the files or just run SETUP.EXE. Maybe Brody can jump in here if there is additional info needed.
