I have a Samsung R70 laptop (2 years old) which has an NVidia 8400 GS graphics card. It's been giving me problems over the past few days for the first time. A message keeps coming up saying the driver has stopped working and the screen goes a funky colour. Sometimes it recovers and sometimes the screen goes blank and I have to reboot.
Checked online and no newer version available of driver than the one I currently have.
How can I sort this if at all?
