Unknow Device nvidia Graphic card

Ok,so basically a while go,was an average day,but an Nvidia notification pop out from my taskbar telling me that a new driver is availbable to update,it was GeForce334.67BetaDriver .I clicked it,and let the installer do the rest,i didnt runned any other programs during the installation,my screen turned black and then my aero theme was gone (no trasnparency) and also my resolution was changed,after that the installer sayed the Nvidia installer Failed,and now i cant play any games,i cant change back to aero.I tried reinstalling it but i get the same result.What can i do?

Btw,i have Nvidia GT-220 graphic card,also on Device manager,its say on Display Adapters: Unknow Device.

It must say Standard Graphics Adapter under Display in the Device Manager .. You do have an on-board Graphics also ..
