HELP!!!  Graphics Card Not Recognized in Windows 7

Hey all,
I'm running a 32 bit version of Windows 7 Ultimate on my 11.6" MacBook Air (Stats Below) and for a while every once in a while I would have to reboot Windows 7 to get it to recognize the GPU. Now it won't recognize it at all and I can only get up to 1024x768 resolution. It works fine in Snow Leopard and shows up in the Windows Performance Information, but has the 320M's memory listed as Zero Megabytes. Has anyone encountered this; does anyone have a solution? Can I use the drivers Nvidia provides on their website to update?

This worked like a charm for me, thank you.  I have this problem on a fairly regular basis, and have various theories about how to prevent it... mainly that you have to unplug all your external USB devices and ethernet connection before shutting down your system... which seems to work a lot of the time, but not all the time, plus I forget to do this piece of "magic" reasonably often - and it might actually just be wrong, but it seems to have descreased the frequency of the problem.  Usually just re-installing Bootcamp over the top of itself solves the problem, sometimes not, at which picking a recent System Restore point usually does the trick... but this last time neither of those solutions worked.  Uninstalling the driver and rebooting worked!!  Smart, should have thought of that myself a long time ago.  Thanks again!!

  • Graphics card not recognized by Windows

    My Mac Pro has its original nVidia 7300 and an upgraded nVidia 8800GT. A game compatibility problem suggested it was time to update the graphics drivers. Everything was working OK until I went to update the nVidia/WindowsXP driver. The Windows Device Manager only sees the 7300, and not the 8800GT. Seems odd, since the display was plugged into the 8800GT, and it worked OK except for the game. However, since Device Manager did not recognize the 8800GT, I could not update its driver. I did upgrade the 7300 driver and this fixed the compatibility problem when I moved the display to the 7300 port.
    I'd like to use the better performance of the 8800GT, but Windows doesn't see it and therefore I can't procede with the upgrade. Is it possible to use this card with Windows?

    Which drivers are you trying to use? the 7300 may not be compatible with the latest, and you need to use Driver Sweeper in Safe Mode to properly update graphics drivers (I saw 3DMark06 go from 5000 to 8000 as a result).

  • Windows 7 on iMac Core Duo - Graphics card not recognized

    I installed Windows 7 along with Boot Camp drivers for Vista 32 bit.
    But my grpahics card ATI X1600 is not recognized by Windows 7 RC.
    Any ideas on how I can get this to work?

    Most likely that means that the driver is returning bad information or crashing.
    Have you updated the driver from AMD's website?

  • Dedicated graphic card not recognized

    Hello there, I have bought a Lenovo G500 with a i3 3110m proccesor 4 gb RAM and an AMD Radeon 8570m graphics card. I have a very big problem now, a couple of hours ago I got a blue screen of death and since then, my dedicated graphics card isn't recognized, only the Intel one. I tried doing a system restore of yesterday when I installed some programs, that didn't work, I did another one for about a week ago, I uninstalled and reinstalled the driver, I even installed an older one to see if anything works, but nothing yet. Something like this happened before but I don't know how it got fixed, I'm asking for someone's help because I really don't know what to do, the notebook is only a couple of months old and I don't think it should be acting this way. Thank you.

  • Why are my PXI cards not recognized by Windows or MAX?

    I have a PXI-1045 chassis connected to a PC through MXI-4.  When I turn the chassis and PC on with a PXI card in slot 2, the message "Windows could not load the installer for DAQDevice.  Contact your hardware vendor for assistance." appears, and the PXI card is not recognized (it is scene by Windows as an unidentifiable PCI Devices, though I have a DAQmx installed).
    More details:
    Windows XP
    LabVIEW 8.0 installed
    TestStand 4.0 installed
    Latest DAQmx 8.XX installed
    NI Scope installed
    NI CAN installed
    MXI-4 PCI card installed in PC and recognized by Windows (as PCI-PCI bridge, and MXI-4 Device)
    I identified PXI chassis 1045 in MAX and on subsequent boot up saw that MAX complained about pxisys or some other ini file (in the chassis status area of the screen) so I configured it as 'other' then put in the PXI-resorce CD and selected the ini file for PXI-1045, MAX no longer complains about pxisys and instead says the chassis is configured properly
    If I have nothing but the PXI MXI-4 card installed in the PXI system and boot up the chassis then the PC, I get no errors
    If I have a card in slot two (I've tried PXI-6509 Industrial Digital IO, PXI-2569 Relay Module, and PXI-5102 Digital Oscilliscope) and boot the chassis then PC, the message "Windows could not load the installer for DAQDevice.  Contact your hardware vendor for assistance." shows up when Windows boots and Windows sees a PCI Device but can't identify any drivers for it. 

    Hello,
    Can you post a screenshot of the problem? Are you switching on the chassis first or the PC? Please make sure that you switch ON chassis and then boot the PC. This typically happens when you have a corrupted installation.  I would suggest downloading the latest version of driver from here and re-installing it.
    Please uninstall all the driver software from computer before installing the new software.

  • Graphics Card Not Recognized under Mavericks Update? MacBook Pro 8,2

    Every since I updated my macbook to mavericks, my dedicated graphics card is not recognized under system profiler or any software on the computer. I have the Macbook Pro 8,2 (late 2011) and the upgraded dedicated GeForce graphics card from the factory. My system is just running off of the integrated intel graphics at this point and there is no option to switch back in system preferences. Is my card just dead in there or did mavericks ignore it? I have no other operating systems to check. Should I just make an applestore appointment and get it looked at?

    Found the solution ... finally!
    Go to your system preferences - energy saver and then check if your Graphics setting is set to »higher performance«. Somehow the update to Mavericks change this setting to »better battery life«
    Now both cards are recognized and running ... however, watch out: since I changed that setting, my fans are going crazy! ... so I'm not sure if I should keep it. It would be much easier if one could change the setting all the time without the need to logout and login again ... well, Apple though good isn't the Holy Grail

  • Graphics card not recognized

    This seems to be an issue with CC, as the graphics processor is recognized just well by CS6. All settings are exactly the same in CC and CS6.

    Most likely that means that the driver is returning bad information or crashing.

    Your Touch is working correctly. Currently, without unsupported third party hacks, the Touch has NO disc mode. It will only show up in iTunes.
    how do i put programes and games in my ipod touch
    Right now, you don't. The SDK is scheduled to be released in Feburary. Then developers will be able to write programs that will be loadable.

  • Video ipod not recognized by windows at all

    My new video ipod suddenly cannot be recognized by Windows. I'm not really sure what happened - one day I was able to plug it in and have iTunes automatically start and sync, and now whenever I plug it in I just get the message "do not disconnect." Also, the iPod is not recognized by Windows - doesn't even show up in "My Computer," though it does show up in "Device Manager" and in the "Safely Remove Hardware" dialogue.
    What could be wrong? I already uninstalled iTunes and Quicktime and reinstalled them, to no luck. I also installed the new iPod system software 1.3 but also no luck. Finally, I uninstalled all of my USB ports and forced Windows to reinstall them, but that didn't work either. The first time I put in the iPod after that I got a dialogue box that it had recongized the new hardware and was installing the iPod, but nothing ever came of it.
    However, both iTunes and my video iPod are fully functional, and I have taken VERY good card of the video iPod.
    Any idea what could be wrong???

    I tried it, setting it to E. It didn't work. Tried the same thing after setting it to disk mode and it didn't work. Just the same old BS about "Do not disconnect," but it isn't recongized anywhere on the system except for Device Manager and the Disk Management tool you mentioned. No acknowledgement from iTunes or in My Computer. Meanwhile both iTunes and my iPod work fine, but they can't communicate with each other.
    I AM GOING INSANE!!!!!!!!!!!!!!!!!!!!! I have tried every trick in the book that I could possibly think of. Not only did I uninstall and reinstall iTunes, QuickTime and the iPod helper, but after I uninstalled them I COMPLETELY nuked them, eliminating every file and clearing extraneous references out of the registry. Then I reinstalled from the CD going by the instructions by the letter. I thought for sure it would work now but for some ridiculous reason it doesn't.
    I am completely at my wits' end.................. What the heck can I do???
    PS: I also have Linux installed in a secondary extended partition, which is on my hard drive but not counted as C. Not sure if that makes any difference.

  • "USB Hardware Not Recognized by Windows"

    Please help. I keep getting an error mssage "USB Hardware not Recognized by Windows" I believe i have tried it all. Uninstalled Itunes. Reinstalled Itunes.
    Okay I just tried pluggin it in as I typed this and it worked. The only thing I did diffrent was I unplugged my External Back-up drive.
    Is this Common? Can anyone help explain this to me?

    I have a combo floppy drive/USB 2.0 card reader and I believe I have the same problem.
    I'm not over-clocking and while USB shows up in WinXP in device manager the card reader is not recognized by the system even though I KNOW I have it connected correctly.  The floppy works fine.
    I believe the 4 USB ports on the mobo are non-functional but can't test it until Thursday sometime.
    Hopefully this is correctable with a BIOs update.
    Anyone else have issues with the USB ports on the mobo and if so, were you able to fix it?  How?

    Hi:
    You notebook is not designed to run a 32 bit operating system and there are no graphics drivers for it from HP.
    You will have to try these steps and if they don't work, I'm afraid you are out of luck...and will need to install a supported 64 bit operating system.
