OK ta, will look into that. I just had a look into seeing whether I am up to date with the drivers and downloaded this from here-
NVIDIA DRIVERS 306.97WHQL
GEFORCE R304 DRIVER
Windows 8 64-bit, Windows 7 64-bit, Windows Vista 64-bit
I checked windows update and no mention of an update on 10-10-12 so not sure if I have the most up to date drivers installed for my graphics cards. How do i check what drivers I have installed, can't find how to do this in Device manager?
