It's probably the sound driver for the HDMI output on the display adapter, as Terminills said.

Microsoft tests (by way of the WHQL process) and distributes drivers developed by OEMs, i.e. Microsoft's Nvidia drivers were developed by Nvidia. Why wouldn't you trust them? I don't usually recommend installing drivers from a CD as they're usually seriously out of date. I only used boxed drivers if I need an HBA driver during installation. Even then, I'll use the latest WHQL driver if I can download it on another computer. (The only other exception would be using something like HP's SmartStart, PSP, or firmware CDs to install bits, as most firms standardize on a particular CD release.)
