Key notes

The Intel SMBus Controller is a chipset on the computer’smotherboardthat monitors the motherboard’s voltage and temperature.
A yellow triangle with an exclamation mark next to the SMBus Controller driver means that Windows does not recognize the hardware. This indicates a driver issue, for instance, an outdated ormissing driver. Fortunately, this can be fixed easily.
