I have a Nvidia GeForce 400 MX video adapter card installed on my computer. This adapter has worked fine before. But recently I have tried to update some of my via ide and usb drivers and then re-installed windows. Since then, my computer shows that there is no video adapter installed. Just a simple VgaSave NonPlugandPlay device. I have tried Reinstalling the device and making sure it's plugged in all the way.

I have also downloaded the latest driver for it off the nvidia website but it did not help.
