Zotac Nvidia Geforce Gtx 650 Drivers REPACK
In the system settings there is an program called "additional drivers" which is very simple, and should give you the ability to install the driver. As for Nvidia, I never had problems, amd is a completele different story(but since you got nvidia, ur fine). Did you uninstall the drivers you installed manually?! Because a clean install would probably give a better outcome ;)
