What is the Graphics Card Software to which you refer ? If this is the disk that came with the card, these will be the drivers for it. If you have Nvidia drivers loaded also, you have 2 lots of drivers installed !
Try this
1. Throw drivers that came with card in bin
2. Uninstall all drivers for card in Windows "Add / Remove Programs"
3. Download latest Nvidia detonator drivers from *
http://www.nvidia.com. These will be the drivers for the FX5200 chip direct from the manufacturer as opposed to those for the card (hence throwing the disk in the bin)
4. Restart PC. Normal boot required (not safe mode)
5. When Windows detects the card, ignore it.
6. Go to .EXE file downloaded from Nvidia site and unpack drivers.
7. Restart PC.
All should be fine. I've installed a number of Nvidia cards in this manner with no problems (FX5200, GF4, GF2)
Hope all OK.
