You may get an unexpected SMBus controller issue in the device manager if you have recently reinstalled the Windows OS, updated to Windows 11, or installed the latest Windows update.

The Intel SMBus Controller is a chipset on the motherboard of a computer that monitors the voltage and temperature of the motherboard.

The SMBus Controller driver has a yellow triangle with an exclamation point next to it, indicating that Windows does not recognize the device. This indicates a driver problem, such as an out-of-date or missing driver. Fortunately, this is a simple repair.

What’s the problem with the SMBus controller?

The problem occurs when the Intel Chipset Device program does not install device drivers for the Intel SMBus Controller (the yellow exclamation mark).

The present SMBus Controller is unable to relay device and hardware information to the OS as a result of this.

The driver is unable to show the right name for the specified hardware in Device Manager due to the error.
