You should download manufacturer specific drivers. NVidia chipset drivers should be the last resort. Who actually makes your card? Go to their website and get those drivers, not NVidia. They might not be the absolute latest and greatest NVidia drivers but they should be the latest drivers that are designed to work with your card. While you're at it, actually check that your card is supported in Windows 7.
Check that there aren't separate 32bit and 64bit drivers, and if there are make sure you're using the appropriate ones.
Stop using crap like GameBooster or whatever the hell is it. Things like that almost never work as well as you think anyway. Get the card working first, then add $#|t later on.
edit: I should have added that if it's an onboard graphics chipset (perhaps with an ASUS motherboard per chance? which explains why you're using obscure "boosting" cr@p) then you need to go to the motherboard manfacturers website).
P.S. If it is onboard graphics then disable it and get a real graphics card. :)
