AMD SMBus driver not installed

[davep90260]

I have an Lenovo g505 Laptop that came with Win8 and upgrade to 8.1. Have been having problems shutting down, especially when installing updates. Getting an error message: DRIVER_POWER_STATE_FAILURE. In device manager, I noticed in the system devices tab that there are 5 devices that don't have drivers installed, the smbus being one. Could this be what is causing the problem, and could it be as simple as clicking the update driver button in the devices properties? Could really use some help here.
