I too have seen this after restoring my system. On both occasions I just deleted it. If I remember correctly it reports that it is installed properly but not functioning. Tested all my hardware and stuff functions correctly so I'm not sure what it is used for. However you can find all your factory installed drivers at C:\eSupport\eDriver or the latest at

I've seen around the forums some users experiencing difficulties after flashing the BIOS (on various ROG notebooks). Do update the graphic card drivers though.
