I recently brought a new hard drive and was going to use it as my primary boot drive and everything. But after I installed windows 7 64-bit pro I can't seem to install the video card driver for a nvidia gtx 660 ti. It installed the Standard VGA graphics adapter for the display. But when I go under Device Managers I only see one item that needs a driver which is a multimedia audio controller, and I suspect this is for the nvidia card also based on my working version of windows device manager. The monitor is plugged into the nvidia card at the moment so it doesn't seem to be mobo connection issue. If I swap out the new harddrive for the old hard drive it works again also. Any suggestions on what I need to do?
