SM bus controller drivers not found

Hello everyone,

After building my new PC 2 days ago, I started installing all the possible drivers from the various manufacturers' websites. Problem: When I go to device manager, it shows me with its nice yellow panel that the drivers for the "SM Bus Controller" are not installed... So I have already done several things:
-Update the device via the manager: It finds nothing.
-Run a driver detection on touslesdrivers.com but that leads me nowhere.
-Uninstall the device in question and reboot to see if Windows would automatically update it, but still nothing.

So I'm coming to you after having done long and endless searches! IPB image

Here’s my configuration:
Motherboard ASUS Z87-PRO
Processor Intel Core i7-4770k
Graphics card MSI GeForce GTX 770
RAM: 8 GB DDR3
HDD: 2 TB
OS: Windows 7 Ultimate 64-bit

Thanks in advance!

PS: I forgot to mention: I don’t have a DVD drive, so I can't run the disc provided with my motherboard.
