Hello!

"Other devices":
-SM Bus Controller
Ethernet-Controller
Ethernet-Controller
-Video Controller (VGA Compatible)
-Audio Device on High Definition Audio Bus
-Audio Device on High Definition Audio Bus
-Unknown Device

Please help.

Thank you for your help!!

Just reinstall all your drivers from your Mobo CD. so it seems to me that SM Bus Controller is a driver of the motherboard that you are probably on the mobo manufacturer site ,

Great! ok so it probably is time to use the installation cd? but I have read that it is better to download the latest versions!
