Pc doesnt see gpu

Hi I just finished my first PC build. Right now I am running off an Asrock Z77 extreme 4, 3570k, 8gb of ram, and windows7 64 bit. Today my brand new GTX 680 came and I was hoping to be playing Crysis 2 or something but the gpu had other ideas. Basically my pc doesn't see the gpu. I checked in device manager as well as the bios and nothing there for a gtx 680.

Here's exactly what I did.

Yesterday the PC was on and running off the mobo's graphics.

Today I seated the gpu into the PCIe slot and plugged in BOTH six pin power cables.

The fan is on so I know the gpu has power.

Any ideas? :o

  1. Are you plugging your monitor cable directly to your graphics card and not the motherboard? If not, there's your problem.
  2. But the pc doesn't even recognize that the card is plugged in. How would that help?
  3. If you're not plugging the monitor into the card, it isn't turned on. You can't detect a turned off device ;).
  4. I plugged the hdmi cable into the card and when I started up the pc there was a blank screen for about 5 minutes. WTF?
  5. and the driver CD is in so idk what to do
  6. You never mentioned what PSU you have. Who knows, maybe its a no name brand junk type of PSU that con't provide enough juice to such a strong card.
  7. its a corsair gold 800w
  8. do i need to disable the onboard graphics or something?
  9. Normally in the BIOS - it gives you an option for onboard/PEG graphics. You would have to make sure your video output is set to your PEG (another word for PCI E add on graphics cards).

    Or if you cannot find such an option, or know where to look:

    You could shut down your computer (unplug it from the power supply as well), take out the watch battery on the motherboard and press the power/reset buttons a few times.

    After a few minutes, make sure your GPU is seated correctly, put the watch battery back in the motherboard, re-connect your power cord to your PSU and turn your computer on - this should automatically make your BIOS select the PCIE graphics card.
  10. Sorry to say this, but if you don't get any picture from the card output it means your card is dead. Your power supply is more than enough, and disabling onboard graphics is not needed. I'd return the card and get another one.

    the video card wont turn on if you dont install the mb chipset drivers. download the newest ones from intel. install them and then reboot. if the card is seen it should show up under device manager..if not use gpu-z and cpu-z to see why..also make sure your using the top pci video slot near the cpu. check for dirt or a bent pin in the pci can also try the other pci slot..just turn the power off when you move the cards.also check your bios..they have a bios patch for video cards and the on board video.
  12. i'm assuming he chipset drivers were the ones on the mb setup disk? if so then yes I installed them.
  13. What are you talking about? You don't need chipset drivers for video to appear on monitor. The card is dead. Case closed.
  14. actually...

    after installing the mobo drivers and the gpu-z the onboard graphics stopped working. and much to my suprise the gpu actually started working in turn.

    maybe it was a fluke but that seems to have done the job and all of the stress tests are going well. thanks guys.

    now the case is closed ;)

  16. tom just to let you know the drivers on the cd are weeks if not months old..
    you want to go to the vendors web page from the driver info on your cd or mb web page and down load the newest ones.
    (intel mei driver)
    sound card and network driver and usb driver if your mb has a 3 party use controller.
