    black screen...AGAIN


    Hi I just today installed Windows 7 x32 on my Sony VGN-FZ460E and everything was working fine but the only thing that kept bugging me was the fact that I was using my integrated graphics card. So I spent all day fiddling with it trying to get it to work and I read around on other forums that the Geforce 8400M GT wasn't compatible on Windows 7, but people were still finding ways around it. I have tried every driver I could find with 13 hours of searching, I've tried messing with the NV_DISP, I've tried to disable the signature driver enforcement with Driver Signature Enforcement Overrider and reinstalling the driver for the graphics card but I can't seem to get anything.

    PCI\VEN_10DE&DEV_0426&SUBSYS_9005104D&REV_A1
    PCI\VEN_10DE&DEV_0426&SUBSYS_9005104D
    PCI\VEN_10DE&DEV_0426&CC_030000
    PCI\VEN_10DE&DEV_0426&CC_0300

    Those are my hardware ID's. If anyone has found a solution I would greatly appreciate it since I start school in about 11 hours..

    Probably not a good idea to mess with things you are unaware of.
    Get your system disc and re-install your OS.

    Here is a win7x32 compatible driver for your 8400M GT

    In your case it is very important to properly uninstall all video software and only install the recommended drivers on a cleaned OS. Thrashing about can leave remnants that can cause driver conflicts.

    First, go to Start > Control Panel > Remove a Program. Find and uninstall all the nVidia Video Programs listed. Do 3D and PhysX first, then the driver (the control panel will uninstall with the driver). Do not restart (yet).

    Go into Windows Explorer/My Computer and look in the C: drive for the nVidia folder. Inside the folder will be driver folders, one for each driver you installed. Delete all the folders. You can leave the main nVidia folder (empty). Your new drivers will be installed here anyway.

    At this point you can restart the computer.
    Note: It may be necessary, in your case, to use a program like DriverSweeper to clean up your registry before attempting the new drivers. But it may be unnecessary. You could skip this step the first time and see how it all works before doing this. You can always redo these steps a second time to try the DriverSweeper method.
    A good tutorial here: Installing and updating drivers in 7
    When the computer restarts it will load to the desktop and Windows will install a generic WDDM 1.1 driver. Let it do this - you need this driver installed before you can install the nVidia drivers. You will be asked to restart again. Do so.

    Back at the desktop you should have working video. This would be a good time to test for problems. If you have video problems running the generic driver then you could be dealing with hardware issues.

    If everything is working OK then you can install the nVidia drivers. Just run the download like usual.

    Can you boot into BIOS at all?

    I've had this happen once after using DriverSweeper.

    When you start the computer, just after the bios finishes, and before windows starts to load, press the F8 key to reach the boot menu.

    One of the options is to Start with VGA graphics, or something similar. This will get you to the desktop at low res graphics.

    Once on the desktop you can try and install the nVidia drivers.

    Alternately, from the boot menu, you could choose Safe Mode. Once on the desktop in Safe Mode you can navigate to the Device Manager and open the properties for the graphics card, and search for drivers. This will normally find the WDDM1.1 Windows driver and install it.

    The nVidia drivers will not install until the graphics card is initialized with a generic driver, so don't bother trying to install the nVidia drivers from within Safe Mode.

    Hope that helps.

    Well I came home today to test out my luck and my monitor started to work again, it was strange I didn't know what had changed since I left for class earlier today but I'm not one to complain. But after doing everything all of you guys had suggested nothing seems to work still. After I install the drivers, the laptop reboots and does its normal thing. Windows logo comes up and goes to a blank screen afterwards and then restarts once again..

    Can you get to the desktop in Safe Mode? (w/no video issues other than the butt-ugly graphics)

    Yea I can get it into safe mode. Thats the only way I can get the laptop to work after I install the Nvidia drivers and the login screen goes blank. I have to manually restart the computer and go into safe mode and uninstall the drivers for it to load normally. The laptop only seems to load normally with the integrated graphics card.
