Answer #1
If you don’t know what your doing download Drivergenius from the apps section. It will update all of your drivers for you. Installing the wrong driver can be quite a headache if your computer excepts it. (Most times it will say wrong driver (at least Intel’s do usually), but not all the time.)
Answer #2
install the chipset driver from intel or your mobo makers site

The SMBus Controller (or system bus controller) is part of the Intel chipset. It monitors your system board’s temperature and voltage. Programs that read your hardware sensors need the controller. Google is your friend.
Answer #5

The System Management Bus (abbreviated to SMBus or SMB) is a simple two-wire bus, derived from I�C and used for communication with low-bandwidth devices on a motherboard, especially power related chips such as a laptop's rechargeable battery subsystem (see Smart Battery Data). Other devices might include temperature, fan or voltage sensors, lid switches and clock chips. PCI add-in cards may connect to a SMBus segment.
