Yesterday I replaces an old GPU in my workstation with a Quadro 600. Of course it comes with an install disk but upon rebooting the computer the new hardware wizard appeared and I decided to give it a try. It halted saying it couldn't find a file called "hdaudiobus.sys". I cancelled out and used the install disk instead which was uneventful. During the install an Nvidia HDAUDIO driver was also installed. Device manager shows all OK but every time I re-boot the new hardware wizard still appears. I haven't noticed any functional problems but the appearance of the "wizard" is annoying. Is there a remedy?
