Basically i have a samsung NP305v5a AD04x model and i upgraded from windows 7 home basic premium to proffesional but i had to install some drivers again. the only driver i cant find is the driver for my SM Bus controller. I have went to the samsung website but nothing is available (unless i have missed it but that unlikely). Is it neccessary for it to have the driver for the smb and where can i get it? Thanks!!!
