Sorry about the delay replying, had to go and help my mum with her computer. I seem to have spent all of today fixing or trying to fix problems with computers.
OK, according to the Device Manager, the driver version for my GeForce card is 2.1.8.3.
Going via the Control Panel -> Display (I'd guess this is the English name for the Monitor setting?) -> Settings -> Advanced -> GeForce2 MX/MX 400, look at the numbers after the file names route, it says 5.13.01.2183.
This any help?
