Missing sm bus controller in device manager asus gryphon z87 I cant find the driver to fix this 11 answers Last reply Dec 23, 2017 Best Answer Dec 23, 2017 More about missing bus controller device. SM Bus - System Management Bus.This is part of the chipset, and, as such, controller and driver issues for it are resolved by installing (or updating) your motherboard chipset drivers. I'm running Windows Vista Ultimate 64-bit. I recently did a system System Diagnostic test on my PC and the test revealed that I needed a SM Bus Controller Device. I went to the Gateway Drivers and Downloads section, did a search to find a SM Bus Controller device, and the search revealed four options: 1. PV9.0.0.1008.zip - Intel Chipset Driver 2. I have gone through hp support forums and almost all drivers are installed except PCI Device and SM Bus controller. I couldn't find it anywhere. Under device manager, these two devices are being shown with yellow exclamation. PCI Device and SM bus controller drivers are missing. SM Bus Controller driver missing I just did a fresh reinstall of windows 7 When I look in device manager the driver for SM Bus Controller is missing and the 'update driver' doesn't fix it.

Here'a my question:
I previously asked the question on this forum: What is a SM Bus Controller Device and I was advised to go to Gateway's Drivers and Downloads Section and do a search. As you can see, it came back with 4 options. I am new to this and I don't know which driver to select. Can you advise? Do I have to uninstall the previous driver (that is not working) before I can install one of the above drivers or will downloading the above drivers download and update and clear up any problems I'm having with the driver.
Thanks for any advice you can give.
