I recently installed a new graphics card (ASUS brand NVIDIA GeForce GT 640) in my computer, but it completely failed to recognize the graphics card as existing. I can run a monitor through the ports on the graphics card, but cannot install the drivers necessary to configure multiple monitors or utilize the graphics capabilities. Upon switching back to the original graphics card (NVIDIA GeForce 9500) I received the same problem.
