G780 Nvidia Card not turning on

Good evening, I recently had to reinstall Windows 7 on my G780, and I downloaded the drivers from the website. I downloaded the Nvidia drivers for the graphics card, but even though I tell the Nvidia control panel to run the card for my programs, it doesn't turn on. I've restarted it and shut it down, and updated to the most current version but it doesn't activate. If anyone's got an ideas or a solution, I'd be happy to hear it. Thanks!

Your problem might be the same as I experienced - migrated network settings that were incompatible with the MBA.

  • GE620 DX, Nvidia card not working properly

    Hello everyone,
    Nvidia support sent me here since updating drivers didn't solve my problem.
    To be honest, I'm not really computer savy... I've been sticking to consoles my entire life because it's always felt like an easy option. Because of my lack of experience I'm not the first person to notice when a computer isn't performing the way it should, therefore it has taken me a while to realize that the Nvidia Geforce GT 635M (2GB GDDR3) card has reset the settings to use the integrated graphics card instead of the Nvidia card (LOL).
    Readjusting the settings doesn't work. The window will freeze for about 2-5 seconds, then refresh and the settings will be back to integrated card. Also, I downloaded new drivers from Nvidia, but the installation failed.
    EDIT:
    The power button is red, not blue (opening task manager does not resolve this).
    Nvidia control panel isn't working. When I try to use it I get a message saying I have no monitor connected to the Nvidia GPU.

    Hello, i'm on laptop:
    Lenovo Y580 (i7 2300Mhz, 8Gb DDR3, GF 660 2Gb DDR5, 256Gb SSD, Windows 7 / Windows 10 TH)
    At first i was using default driver from windows th, but some games (styx / bioshock) won't even launch, clicking on exe file didn't do anything. Then i've updated driver:
    intel - 15.33.30.64.3958
    nvidia - 344.60
    And now these games are working, but they are only on intel. I tried to force nvidia in several ways, but no luck. Though some other apps (3dmark06) are working on nvidia card. 
    And switching game to dx9 (where it possible) solves the issue.

  • MSI GE60 2OE - Nvidia card not recognized after shutting off the laptop

    So I received my laptop from RMA some days ago. It was just coz the plastic hinge of the screen, broke.
    When I received it, I had some Windows problems.So I reinstalled  it 3 times, the last one from a different ISO (all were official 8.1 windows isos). The last time seemed to work fine, until I noticed I had a problem. Everytime I turn off the laptop, and turn it on, the nvidia card (765M GTX) isnt recognized. It doesnt appear in device manager at all, or it appears as unknown 3D device.I have to uninstall intel gfx drivers, nvidia drivers, and run Display Driver Uninstaller , so the drivers recognize the card again. But if I shutdown the laptop, then I have to repeat this process again...
    I tried different drivers, updated other component drivers from http://www.station-drivers.com/ , I have the latest BIOS, etc..
    When the card is being recognized, it works fine, no overheating nor artifacts in games.
    What can it be?

    have you done OS restore to factory default?
    or a new fresh OS installation?
    Or when you turn it off,
    then boot to DOS and see if nvflash will see the card
    this will help to isolate if its Win OS issue or something else hardware related

  • NVidia card not receiving interupts

    I like Arch so far but I decided to set up a window manager on it but I can't seem to get X working with anything other than the vesa driver. When X crashes on the nVidia drive, I get this:
    (**) NVIDIA(0): Depth 16, (--) framebuffer bpp 16

    After looking in the readme, I tried adding some extra boot options but they didn't seem to work plus I already have noacpi turned on otherwise I can't even boot into the system. It works fine with vesa so I assume the config file is set up right but I can't seem to figure out what the problem is. My graphics card is a GeForce 7300GT and is installed in the only PCI-e slot I have.

    Out of curiosity, what version(s) of the NVidia driver have you tried? The last 2 or 3 released versions of the driver have had the Common Problems in chapter 8, and the latest driver mentions: Improved interaction with ATi RS480/482 based mainboards. (Not sure exactly what chipset you have, but perhaps there'll be fixes for that one too).
    Try one of these: http://www.nvidia.com/object/unix.html
    If one of those doesn't work, perhaps try: http://www.nzone.com/object/nzone_downl … river.html
    And if any of those don't work, take a hammer to the motherboard, it's so very obviously asking for it .

  • 875p and 7 series nvidia cards not compatible?

    as mentioned above, I have the MSI 875p mb.  I currently have an nVidia 6800GS that works like a charm in it.  I have tried a 7800GS (XFX) and a 7600GT and both of them will not work, in anaolg or digital mode.  The mb will POST as normal, the screen will go blank as it normally does prior to the Sp splash screen coming up I'll get a no signal msg then my flat screen goes into sleep mode. Anyone run into this issue?
    P4 3gig
    1g Kingston Value ramRam 2x512
    msi 875p Neo
    Turbolink 420W PS Max amps:  28A, 40A, 18A
    SB Audigy

    Can you still boot with the 6800?  If so, download the program called DriverCleaner Pro and install it--go into control panel and uninstall the graphics driver, reboot into safe mode and run DriverCleaner Pro to get rid of leftover nvidia junk, open Device manager and right click on the 6800 listed and click uninstall. Shut down your machine, remove the 6800, install the 7XXX card, boot-up, hit cancel if you get the chance so windows doesn't install drivers and uses the standard VGA drivers.  If you are now into windows, install the drivers off your installation CD or, download the 84.21 drivers from nVidia and use them.

  • Nvidia Card not being shown in Device Manager

    So I recently installed Windows 8.1 and fully updated. But no matter how many times I uninstall "Microsoft Basic Display Adapter", the Windows isn't detecting my card to install the appropriate driver.
    Back in the day when I first installed windows 8, the card was detected and it automatically installed Nvidia drivers from Windows update but not this time.
    Anyone know how can I get the card to show up in the device manager?

    Sorry I forgot to mention.
    Qosmio F 50 -126
    Graphic Card : Nvidia 9700m GTS.
    Right now I'm running on Microsoft Basic Display Adapter from 2006.
    This is very frustrating.

  • Airport Card Not Turning On

    I purchased my MBA yesterday and performed setup at a local coffee shop with a dummy account just to play around with my new machine before I got home and had no problem getting connected to the wireless. A little later in the day I got around to actually connecting my iMac backup drive to use with the Migration Assistant on my new MBA. After transferring my files and settings over along with my user profile, I am no longer able to establish a connection with ANY wireless access point.
    I have tried resetting my network settings as well as multiple reboots but nothing seems to resolve my issue - being that when I go to the wireless icon at the top it always says "airport not configured." When I go into network settings and attempt to configure my system it lets me turn airport on and off in the menu, but when I go into the system information it shows the airport as being off no matter how it is set in the preferences menu. Basically I am completely unable to get it to establish any kind of connection to any router. It was able to pick up my linksys WRT54G once when I told it to search for wireless access points but has been unable to replicate this action since.
    Is anyone else experiencing this problem? I'm currently in the process of reloading my user account from my iMac using Migration Assistant in hopes that this reload will remedy the issue. If anyone has any tips please let me know.

    Your problem might be the same as I experienced - migrated network settings that were incompatible with the MBA.

  • NVIDIA card not showing up, VGA adapter reports problem

    Hi all,
    I am running a W520 which has a NVIDIA Quadro 1000M, but I have an issue with installing the NVIDIA properly.
    In device manager, only the Intel HD Graphics family and Standard VGA Graphics adapter show up. The VGA Graphics adapter reports a "problem (10)".
    Link to picture
    When I try to install the latest driver from NVIDIA, I get an error message, stating: "You must install an Intel driver first."
    Link to picture
    The NVIDIA control panel states:
    Does anyone have the same issue? In general, my computer runs fine. I would like to use the NVIDIA only for the CUDA cores, not to hook up another display.
    I hope this will work finally without opening a can of worms.
    Thanks!

  • External Display will not turn back on after sleep

    Just bought a new MBP last week and gave my wife the MB. I typically attach to an external 24" display and run in closed clamshell mode. I have been doing it for quite some time with no issues. Now with the new MBP if the energy saver kicks in and turns off the display, and/or the energy saver puts the computer to sleep when I attempt to wake it up the display flashes then goes blank. There is no way to turn it back on. When I open the clamshell the internal display will only show some random pixels and a white line at the top of the screen. There is no way to correct it unless I shut down the machine.
    I am running with the Nvidia card, not the internal Nvidia. If I manually put the computer to sleep it will wake normally with no screen issues. It will also not act up if the external display is not connected.
    Any help or suggestions of a setting I might have wrong that would cause this?

    It is a Gateway FHD2400. Connected from mini display to HDMI. My previous MB was connected to the same monitor for the last year with 0 issues. It was connected mini dvi to VGA.
    The issue is strange because it only happens when the computer turns off the screen or sleep. When I put it in sleep it doesn't happen.

  • Iphoto 9.5.1 displays only raw photos correctly.  If I correct redeye or touch up a photo I get white boxes over the eyes(if correcting redeye) or the thumbnail and photo turns mostly white. Note: I have an NVIDIA card.

    Do you remember the days when Apple wrote robust code ?  The latest updates have not been great. 
    Maybe the programers are outsourced to a foriegn country now or Noobs out of school ?
    It looks like someone isn't paying attention to the editing layer... I write code.  and when you edit an image you store the update in another layer. The method enables you to easily undo edits.   I "upgraded" to 10.9.1 and was forced to update iPhoto.    After I uploaded photos from my camera I noticed redeye reduction results in just white squares over the eyes. I also noticed issues if I attempt any photo edit funcition in iPhoto.
    This means to me that iPhoto 's editor is saving video from the wrong memory location.
    I have a NVIDIA card because I write CUDA applications on my Mac.  An NVIDIA card enables me to write CUDA and OpenCL apps.
    Here's what happens if I attempt to straighten an image:

    As you can see Mavericks may have made some improvements but overall it does not get the job done as it used to.
    I am willing to bet  that your graphics code has devolved into ATI centric code.    
    I booted into macos 7.5.1 and the issue with the same hardware older operating system and apps works fine.    I just wish I never deleted my 10.6.8 install.  10.6.8 was the most stable on the MacPro.   Everything worked.     From 10.7 up I've noticed a decline in dependability.
    Can you please fix this or design a work around ?    Switching over to an ATI graphics card is NOT a good answer.  
    Also I noticed Cinebench R15 benchmarks are higher in 7.5.1 verses 10.9.1

    Where in that other topic is the manufacturer of the graphic card or even a graphic card mentioned.?  You may have known what kind of card you had but we're not mind readers.
    Since it appears to be a incompatibility between that particular card, Mavericks and iPhoto you should keep telling Apple about it by contacting them via
    http://www.apple.com/feedback/iphoto.html
    http://www.apple.com/feedback/macosx.html
    http://www.apple.com/feedback/macbookpro.html
    http://www.apple.com/feedback/mac-pro.html
    whichever is appropriate for your particular situation.  It's the squeaky wheel that gets the attention.

  • I bought 2 new memory card to 4 grams each - replace them in your MacBook Pro 13-inch but it will not turn on - If you are installing a card for 2 and one for 4 d all works - tell me what could be the problem

    I assume that you have installed new RAM in your MBP.
    It would be helpful if you indicated the EXACT model/year MBP that you have.
    What the the RAM specifications that you are trying to install?

  • [SOLVED] Bumblebee/bbswitch Not Disabling Nvidia Card

    Hello all.  I've been able to resolve a wide variety of problems by searching through the posts here, but it seems I've come up empty on this one.
    I'm running Arch on a Sager NP5160 (Clevo W150HN), i7-2630 QM, 8 GB RAM, running Optimus with an Nvidia GT 540M Optimus setup.
    I've had Bumblebee and bbswitch running fine in the past, but recently I needed to reinstall Arch (my own fault).
    I installed bumblebee and bbswitch again, as described on the wiki. 
    However, once everything is installed and configured, bbswitch is still unable to deactivate my Nvidia card.
    I'm using the proprietary Nvidia driver.
    I have verified that bumblebee.conf has the driver set to Nvidia (not nouveau), and uses bbswitch.
    I have also tried blacklisting both nouveau and nvidia, as well as adding bbswitch to the modules section of my mkinitcpio.conf file (and regenerating the initramfs).
    A curious point that I have noted is that the Nvidia card is disabled during boot, and up until I login.
    Once my information loads, the Nvidia card is activated and I cannot deactivate it, even manually.
    Here is the dmesg output when I run glxspheres64 using bumblebee:

    Sorry to bump this, but I've found some more information.
    Unfortunately, I'm not sure what to do with it yet.
    I've uninstalled and reinstalled the relevant packages outlined in the Bumblebee wiki.
    When my laptop boots, the Nvidia card is disabled up until I log in, at which point it appears to be perpetually enabled, unless the Optimus indicator lights are showing incorrectly.
    This is the log output I receive when I run optimus glxspheres64:

    Any thoughts?

  • HT4628 I did the security update on 4-2-13 and now my airport card will not turn on. OS 10.6.8 Intel imac 4,1 core duo. My macbook pro did not have this issue and wifi here is working on that. Is there a setting that was changed? Thank you!

    Airport card will not turn on after security update yesterday. worked normally (for the download of the update) until then. Wifi here works fine with my Macbook Pro right now so the issue is with the card / computer / software not the provider. Did the update change something?

  • Macbook Pro Retina - nVidia card does not work correctly

    Hi,
    having a MacBook Pro Retina. It ran fine till yeasterday when I fired up a game which was laggy and it was running fine before. It took me several hours to find where the problem is and it seems to me that the nVidia dicrete card is not working. But strangely not working. I installed gfxCardStatus to see whether the card is being switched to run the game and it actually is. But the performance is the same as running it on an internal Intel. I took another test and downloaded CINEBENCH to see the differences and sadly the results are the same if I switch to nVidia or to Intel and run the benchmark.
    Obviously something is not right here. It happened over night. Before it worked corectly. I do not remember installing something that day/night that could have broken it (in case it is a SW problem). Only one thing comes to my mind - Apple Java update. But I tried to uninstall it and got the same result. I did try to restart several times. But otherwise there is no visible flaw, e.g. flickering or black screen when swithech do nVidia - nothing. gfxCardStatus shows that the system switches the card and I notice no change. Only in heavy load it is obvious that it is slow (slower than it was).
    Is there a way to see if the nVidia card is working? I suspect that even if the system is trying to switch to a discreet card it still runs on the Intel in reality. Any way how to distinguish this rather than to rely on gfxCardStatus? Any log that would make this clear? Any test I can run (Apple HW test shows "no problem detected")?
    Many thanks for hints.

    To show what I am talkin about I did another test. I downloaded and ran LuxMark. There it is possible to test CPU and GPU separately on a same benchmark scene. FIrst I let the system switch to nvidia and did the test:
    Then I manually switched to Intel/CPU in gfxCardStatus and also selected CPU in the LuxMark and did the same test. The result is:
    You see? How it is possible that in OpenCL computation CPU with internal graphic card is even faster then the descreet one? This is what I am experiencing now and cannot figure out where the problem lies.
    Would the Apple HW test discover a dead nvidia card? Because nothing shows that the card is dead but as you can see it is not performing as it should.

  • M-Audio Audiophile 2496 PCI card installed, now computer will not turn off

    I installed Audiophile 2496 card + "live lite 4" software and now my computer will not turn off. It goes through the motions, but than just reboots. I have to hold the start button to kill it. I also have a Firmtek SATA PCI card and a USB 2.0 PCI card. Is there some way to solve this short of pulling the card?

    Hi-
    Do you have the proper driver version installed?
