Nvidia does not currently have Windows 10 a driver for that card. They also never released 8.1 drivers.
I think the card is just not going to get the updated driver required for Windows 10. The basic driver is very limited as well.
If the rest of the system meets/exceeds the requirments, you may be able to get another video card. Make sure it matches the old ones interface(AGP/PCI-E/ECT), you have the power requirements and has drivers support.
Honestly, You may be better off just sticking with 7 if the system is older.
