Windows 7: Missing driver for SM Bus Controller on new SSD Win7 installation

Missing driver for SM Bus Controller on new SSD Win7 installation

I recently bought a samsung 840 series 250 gb ssd (not showing on my system specs yet) and after installing windows fresh and downloading drivers from asus and nvidia, i looked in device manager and cleared up some missing drivers, but i can't seem to fix this missing sm bus controller. I tried using the thing on the intel site to detect the drivers but the MEI and SATA controllers don't fix the problem in device manager. In addition, the new version (4.1) of samsung magician freezes my computer and I don't exactly know why.
I used the instructions from this site Sean's Windows 7 Install & Optimization Guide for SSDs & HDDs.

The System Management Bus, or SMBus, is essentially a wire on a computer's motherboard used to transfer information between the processor and various peripheral devices.

Apparently created by Intel and began in 1995? [and quite slow/obsolete now]

I have a Samsung 840 PRO, 128gig SSD, and I don't use anything extra, I stay away from OEM apps unless given a good reason.... is there any for that Magician?

I installed the 3.2 version and it works fine, I guess i'll just keep this version until they update it again. Thanks for the help guys.
