I am running Vista Home Premium and just happened to look at my programmes file the other day and was surprised to see the NVIDIA size was 3.76GB and was downloaded only recently. I didn't do it so is it automatic? Do I need all this as I don't do any gaming or that sort of stuff. Can I get rid of some of this or do I need it all? My Graphic Card is GE Force 6150 LE whatever that means! I would be grateful for any help on this, thanks. Rob
