Hmm, that is unusual for an nVidia card in my experience. I would suggest that you look for the model number and manufacturer on the laptop (it is usually on a sticker on the bottom). Then go to the manufacturer's website, and look for drivers. They will probably have windows 7 drivers on their site, for the graphics card and otherwise. If the nVidia software is failing to directly identify your drivers, which is highly unusual, then you're pretty much limited to getting the drivers directly from the manufacturer (i.e. IBM, Dell, Sony, HP, whatever).
They should be able to fix you up, at any rate. But there are almost no games you'd be able to play off the Standard VGA driver, since that doesn't support hardware acceleration of any kind to my knowledge, and only supports something like 640x480 resolution in most cases (at least on XP -- not sure about Win7, though that's what I'm running also).
Hope that helps!
