Thank you Zantium. It is NVIDIA GeForce 210M which I know is rather old but I stupidly thought I could just download the latest thing they had on their website.
The operating system is Windows 7 64 bit.
Do I have to buy another laptop to get a super duper driver :) The Sony Vaio I have is just over 3 years old and I do like it so I don't want to say goodbye to it just yet.
I have just spoken to someone who says I should go to the Sony website and not the NVIDIA. Is that a valid point?
