For anyone with a series 8 or 9 Nvidia card there is an updated driver for it, it can be found here. (version 180.48)

The strange thing is when I uninstalled the older Nvidia graphics drivers and rebooted to install the newer ones it said there had been significant changes to the computers hardware and I had 3 days to reactivate XP, it reactivated over the net with no problems.
As I have not upgraded this computer for 6 months I will put it down to a quirk of Microsoft.
