That graphic card doesn't have the minimum amount of memory needed for the Window manager, and it doesn't possess the latest shader techs needed for almost every game. Furthermore it is way too old and for that reason, no developpers have made a driver Windows 7, and there will be no drivers for Windows 8 as well.
Install Windows XP or simply use Ubuntu as both supports that card.
If you still want to use that crappy card that won't be able to do anything, you could try this driver (it's a beta driver but it is the only driver set that MAY work on Vista):
ForceWare 97.46 Windows Vista (x86)
