Hi, I have just reinstalled windows 7 on my Sony Vaio VGN-FZ21E. Since the install my Nvidia GeForce 8400M GT graphics card is not detected. I cannot see it in device manager and when I try to install the Nvidia drivers, it says there was no card detected. It has worked fine for 2 years until the Windows 7 reinstall. *I have a dual boot system with Ubuntu and Ubuntu detects the card just fine. Can anyone help?
