I am trying to fix SM Bus Controller in the Device Manger, it shows a yellow '!' beside it and I did some research and it looks like it has to do with the chipset, so I downloaded the latest one for my motherboard but it did not fix anything, anyone know how to fix this? Step by step tutorial would be great. Also sorry if this is the wrong place to ask this question I thought this would be the best part of the forums to ask this question since it is related to the motherboard.
Motherboard: ASUS ROG MAXIMUS VI HERO 1150 Z87 Chipset.
P.S: This is on Windows 8.1
