Just done a clean install of windows 7 on my Sony VPN-SZ5VWN and it has installed all drivers apart from the display.
It has a nVidia Go 7400 however when I try to install it it just states there is no nividia products.
If I try to uninstall the VGA driver, it asks me to restart and then, before I can do anything, it reinstalls the standard VGA adapter driver. I do get a solution saying to download the driver however this does not work.
The original drivers are for Vista and Sony provides no other supported OS for them.
