The "High Definition Audio Device" usually indicates a generic sound driver
installed by Windows.
I see you have other devices with problems too (e.g. Ethernet Controller). In many installations, there are motherboard chipset drivers
and if your motherboard has separate chipset drivers, they must be installed before installing device drivers. One of the prime things the chipset drivers do is define (identify) all the devices on the motherboard.
Usually the Win 7 install will install most of the drivers, but in this case it appears that not all the drivers were installed and thus some devices will not install or incorrect drivers are installed.
