Hi:
These two drivers should install all devices...Restart the PC after installing the first driver.
This package contains the Intel Chipset Installation Utility. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager.

This package contains the driver that enables the Intel Dynamic Platform and Thermal Framework firmware. Intel Dynamic Platform and Thermal Framework provide system temperature and power utilization information for the system thermal protection to function properly. This package is provided for supported notebook models running a supported operating system.

Unfortunately, I wouldn't be able to help you with the search issue.
I suggest you start a new post on that if installing the above drivers doesn't by some miracle, resolve that problem too.
