Here is the solution that works. It is not a Modem, a audio driver
, etc. Most people want to have you reinstall windows when that is not neccessary.
Error on PCI Simple Communications Controller
If the Intel® Management Engine (Intel ME) driver has not been successfully installed, you may see an error on a "PCI Simple Communications Controller" in Device Manager.
To resolve this issue, install the Intel® Management Engine Interface driver for your desktop board. This driver can be installed from either:
The Express Installer CD that came with your board (in the Software\Driver\Advance_Fan_Speed_Control__AFSC folder)
The latest driver downloaded from Intel's Download Center.
this worked on all our lab computers and my home PC.
