Receiving “SM Bus Controller doesn’t have a driver” message on your Windows 10?

It means the SM Bus Controller Driver is missing. You can find a yellow ! mark over the SM Bus Controller shown in Device Manager.

Don’t worry. Usually, this is an easy-to-fix issue. Just go with the tried-and-true ways below, you can fix it at once.

Note: SM Bus, short for System Management Bus, is part of the chipset. So its controller and driver issues are resolved by installing your motherboard chipset drivers.

Pick the way you prefer:

  1. Download Intel Chipset Drivers Manually
  2. Download Intel Chipset Drivers Automatically 

Way 1: Download Intel Chipset Drivers Manually

1) Go to the Intel Downloads Center.

2) Type Intel chipset drivers into the search box. Set the product to be chipsets.

3) Choose Drivers as the download type and Windows 10 as the operating system from the drop-down menu.

4) Click the drivers file name with the latest date.

5) Click the .exe file to download.

6) Double-click on the downloaded file to install by prompts on the screen. After it’s done, reboot your Windows 10 to get the driver to work.

Way 2: Download Intel Chipset Drivers Automatically

If you don’t have the time, patience or computer skills to update the Intel Chipset driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks:

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the  Pro version – you’ll be prompted to upgrade when you click Update All).

Note: You can do it for free if you like, but it’s partly manual.
