How do i fix SM bus controller not installed error ?  

Lately whenever i plug in my usb, my pc won't detect the usb and won't read it. After i use trouble shoot, it sends out an error called "SM bus controller not installed". I have tried to fix this problem but it didn't work. Could someone help me please ?

As Maxie says mate and it would be nice for some system specs to work with
System Info - See Your System Specs we might be able to find the drivers for you if you are not familiar with them.

Another good system details finder in HW Info HWiNFO, HWiNFO32/64 - Download se my pic for and example

Thanks for the system spec my friend but i still wonder on how to fix this error. To be more specific, where exactly can i find my driverS for NET WORK CONTROLLER, SM BUS CONTROLLER and finally USB controller? I have tried to download the manufacture website but i couldn't find it. Can you help me? Thanks
