Problems with video card driver on VAIO VGN-FZ31M

My notebook is a few years old but still in very good shape. It originally came with VISTA but I upgraded to WINDOWS 7 32bit as soon as it became available. Everything worked well. Lately I have installed a 500Gb SSD and, rather than cloning the HDD onto the SSD, I went for a clean W7 install. The installation went well but I cannot get video HW acceleration to work since Windows installed a generic VGA driver, which lets me select the 1280x800 resolution but no graphics acceleration. The GPU in the notebook is a NVIDIA GeForce 8400M GT. However, every time I get the proper driver from Windows Update or NVIDIA and try to install it I get the dreaded blue screen upon reboot and the only solution is to boot into safe mode and restore the system to the situation before the driver was installed. It seems that many VAIOs using the same GPU had hardware problems and, at the time (2010), NVIDIA was fixing them for free which I doubt would still be applicable today. At any rate, the very same notebook DID work very well in its previous configuration (Windows 7 on an HDD which I still have). Any idea on a possible solution? Of course, I could just re-install the HDD but I would like to keep the SSD with the new Windows 7 installation since it is meant for another user and it is also in another language. Thanks in advance.

Testimonial: "Thanks JonSnell Electronic. As you say, VISTA is history and I am not going back to it. The problem I describe occurs with any new W7 installation. I even tried buting an expensive W8.1 licence but to no avail. Things only seem to work with the previous W7 installation (upgrade from VISTA...). SONY unfortunately does not have the W7 drivers available for download. Cheers"

SOURCE: Screen/graphics problem, distortions & low res issues

It is not a driver failure but it is a hardware failure. I have my own fz340e and have the same problem as yours. Now, my fz340e works fine.

Need to make sure the video drivers are installed. Go here to get them:

Go to the video and then download the driver that says Original - Mobile Intel® Express Chipset Family Graphics Driver

Download it and then install it. At that point you'll be able to move your resolution to whatever you want it to go.
