Hi:

For the smbus controller, download and install the Intel chipset driver from the link below.  Then restart the PC

You want the 2nd file listed down on the left side of the webpage. 

https://downloadcenter.intel.com/download/20775/Intel-Chipset-Device-Software-INF-Update-Utility-?pr...

For the PCI device, download, unzip and run the setup application from the first driver on the list.

I can't help you with the 3rd issue.
