That's an ancient card and was never fully supported even on Vista. Best you could hope for is try the XP
driver,
found here, and try installing it under Compatibility Mode (XPSP2) and 'As Admin'.
EDIT; Had to confirm but that card doesn't support 2.0 shaders, no Aero support is possible. It will be tough to get that running right in Windows 7 but worth a try.
EDIT 2:
Is this your card? It sounds like 'hacked'
drivers were made available for Vista users. Not that I trust this source but it may be something to look into...
