    iHi Christina,

    I have the same graphics card as yours on Sony Vaio VGN-AR51E and it can be done. Keep on trying. It took me a while but the results are worth it. I kept on trying and then it just loaded properly, as if by accident! Try this link, if you haven't already.. NVIDIA Driver - Convert from Desktop to Mobile (Laptop)
    Make sure you have the latest DESKTOP driver from Nvidia to modify - though it sounds strange!

    God bless

    I wish I could try this, but for some stupid reason I can't even download the original driver from nvidia's website. I click search and nothing happens. Now, I've done it before and I got to the download page no problem. Why is this computer determined to drive me nuts?

    I finally managed to d/l the driver from nvidia, but messing around with the .inf just isn't for me. It's too confusing when you don't know wtf you're doing. I guess I'll wait for another solution or whatever.
    Thanks for giving me this link anyway!

    Hi again,

    Just in case you want to try my modified INF that worked for me, please find it attached.

    You have already downloaded the latest desktop driver from Nvidia. It will likely be extracted in C:\Nvidia

    Download my attachment and extract. Copy and paste NV_DISP.inf directly over by overwriting existing one at C:\NVIDIA\DisplayDriver\191.07\WinVista_Win7\English or wherever it is to be found.

    Right click standard vga in device manager.Then click, Update driver software. Browse. Let me pick. Have disk. Browse. Now navigate to the same folder as before and double click on NV_DISP.inf. Hit ok. Reboot when done, if necessary. Enjoy your gaming!

    God bless,

    Ray

    Windows 7 32-Bit (x86) wont detect 8400M GT


    This worked for me and I hope it will work for you.

    Just so you know, this worked on my:

    17" SONY VAIO Laptop
    Model# VGARN520E
    NVIDIA GeForce 8400M GT
    Running Windows 7 32-bit (x84)

    *Symptom: Your system reads "Standard VGA Adapter" or something similar in the device manager. You can't figure out how to make your NVIDIA card pop up. While you've already tried to download and install the latest drivers from NVIDIA, they wouldn't install, claiming that you didn't have the right drivers for your hardware.

    After hours of going through the .inf file tutorial and only coming up with garbled graphics (I must've been doing something wrong), I found a much easier and less complicated way out:

    *Open a window
    go to "Computer"
    go to "Local Disc C:"
    go to "Windows.old" (If you don't have this folder, skip to end)
    go to "Windows"
    go to "DRIVERS"
    go to the folder that starts with "Graphics Driver (NVIDIA),..."
    run the Setup in this folder
    follow all prompts
    restart when done
    enjoy!

    By doing this, you are merely installing the older driver that made your card work on your previous OS, which was most likely Vista, right?

    IF YOU DON'T HAVE Windows.old-

    Windows.old, as far as I know, is a folder containing a lot if not all of the older files that your previous version of Windows used to operate. The presence of this folder usually results from UPGRADING from one OS to the next, example: Vista to 7.

    If you don't have this folder, you must have either deleted it, or maybe Windows 7 was the first OS installed on your computer either from factory or from it's last C drive format (wipe). This means that you have one of three options. You could:

    1. Tinker around on this website and learn how to download the right update, create and/or copy over the right .inf file, and do the whole tutorial thing. (This was beyond me really. I invested the time but all I got was garbled graphics after about 15 mins every time, which means I wasn't doing something right.)

    2. If your machine is old enough to install Vista, you could back up ALL of your precious files onto an external hard drive, format your C drive, install Vista, CHECK THAT VISTA IS RUNNING/DETECTING YOUR GRAPHICS CARD, then upgrade to Windows 7, and SELECT WHICHEVER OPTION "UPGRADE" OR "CUSTOM" THAT LETS YOU KEEP WINDOWS.OLD, now that you're back at Windows 7, follow the steps at the top. This is a time consuming but surefire way to do it, so long as you know how to properly format and partition your machine, and install a fresh OS.

    3. Continue searching the internet for other solutions, but you may only get so far.

    Personally, I like the second option the best. There's nothing like wiping your computer and starting over. I hope this helps!

    Hello,

    i'm having a problem with my Compaq persario CQ50-211NR laptop. I have windows 7 ultimate 32 bit and i am trying to connect to an external monitor(synaps) It wont detect the VGA ports. (basically when i go to detect the monitor, all i see is my main laptop monitor, no number 2)

    the device manager says "standard VGA..." etc.
    the hardware IDS says
    PCI\VEN_10DE&DEV_0845&SUBSYS_360A103C&REV_A2
    PCI\VEN_10DE&DEV_0845&SUBSYS_360A103C
    PCI\VEN_10DE&DEV_0845&CC_030000
    PCI\VEN_10DE&DEV_0845&CC_0300

    See and heres another problem, the reason i am using the external monitor is because i am waiting on parts to fix my laptop, part of the LCD cracked inside and i could barely see to get my hardware IDS, right now i am using another computer. I plan on putting the driver on a USB or CD and transfer it over, any tips and advice would be amazing.

    Thanks.
