I'm running windows 7 ultimate x64. I also run snow leopard and had the corresponding version of boot camp installed (3.0 I believe).

I installed bootcamp 3.1 when the apple software update suggested it. It said it installed but on reboot it has messed up my graphics card - in device manager it shows as an unknown device. I can't install any nvidia drivers (they just fail saying that nothing was altered), I've tried uninstalling bootcamp 3.1 and reinstallling 3.0 but it's still the same - no graphics drivers and I can't install any new ones?

How can I get the nvidia drivers to install? I've tried from all sorts of sources and no luck. I tried using drivesweeper to clean the drivers off (after uninstaling them) but on reboot it says the same ones are still there. What do I have to do to undo the damage Apple have done?

thanks for any help,


macbook pro, Mac OS X (10.6.2)

    Hi, sorry im not much help but...

    I am running windows xp in boot camp and i updated as apple software update recommended, last night, and i am having the same problem i rebooted and now the screen resolution is stuck in 640 resolution with 4 bit colour and when i try to update the drivers for the NVIDIA 9600 GT graphics adapter it wont go through, i have tried installing from the nvidia website, but when it tries to install, it gives me an error saying no such hardware is found... which is bull**! any clue whats going on?

    is there anyway to fix this without rolling back with the apple install disc... (which i dont have with me on my trip)... but any answer towards solving is appreciated.

    Hello jezgdavies,

    Just an FYI for you.

    It is always best to check with the software manufacturer FIRST. They will tell you if they have tested the product and the version, as well as whether or not it will work with Windows 7.
    Check out the Windows 7 Compatibility site: (There you will find out about hardware and software compatibility.)
    There is a pulldown from which you can choose "hardware" and "software".

    There are also some great articles, instructional videos and such to help with your Windows 7 at our Springboard site:

    In any event a lot of the times, Vista drivers will work in lieu of Windows 7 drivers, however, it's not 100%!

    As stated previously, it's best to have the Windows 7 certified drivers installed.
    Thanks again,

    Hrm, it's been ages since the op, but here's my 2 cents.

    I have a macbook pro with windows 7 ultimate x64 installed through bootcamp 3.1. Here is how I ensure clean driver installs.

    1. Download Driver Sweeper
    2. Install
    (make sure to let driver sweeper run as admin)
    3. Uninstall graphics driver
    4. Reboot into safe mode
    5. run driver sweeper
    6. check nvidia display box
    7. click analyze
    (should list all the nvidia related files, folder, registry entries left behind)
    8. click clean
    9. reboot normally
    10. reinstall desired graphics driver
    (i use 197.16 w/out any problems so far)
    11. reboot

    Also, as a nice, but probably not necessary step, when I'm in safe mode and after I have used driver sweeper, I like to run Auglogics Boostspeed to do a quick junk file scan, track eraser scan, and advanced registry scan before I reboot normally. This is the method I use whenever I install/uninstall graphics drivers. I've never had to deal with bad installs since I started to use this method.

    This method works with all driver types listed in driver sweeper and if it's something not listed in driver sweeper, I've found doing a reg/file clean in safe mode with a reliable cleaner does the trick.

    If it's still not working I'd restore to before bootcamp installation or uninstall bootcamp and the graphics driver. Do a reg/file clean. Finally reinstall bootcamp, and restart from step 3 listed above.

    IF IT STILL doesn't work out, I'd do a fresh reinstall following this guide:

    Hope this helps.
