Quick Fix
Automatically download & update the correct version of SM Bus Controller driver with one click!
What is the SM Bus Controller?
The SM Bus Controller is a chipset on the motherboard. Its main purpose is to monitor the voltage and temperature of the motherboard. If you see a question mark in front of the SM Bus Controller, it indicates that the hardware is not recognized by Windows. A yellow warning icon in front of it indicates that the SM Bus Controller is not installed or the driver is not installed correctly.
There are two ways to update your SM Bus Controller driver:
Method 1 – Download and install the driver manually
Intel keeps updating drivers. To get them, you need to go to Intel’s official website, find the drivers corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually.
Once you’ve downloaded the correct drivers for your system, double-click on the downloaded file and follow the on-screen instructions to install the driver.
