how do i get the latest Nvidia drivers (310.19 ) for my gt650m card, 304.14 is current driver. do i need to do a package request here on the forums

. I had downloaded them , but the install was a bit too complicated for me and i mucked up my machine , and had too reinstall PCL . any help or ideas would be greatly appreciated . id like to get my laptop(acer v-771-9875) up too date with all the latest drivers to enable all the features , especially power managment.
thanks
