Installed new Graphics Card and display does not turn on

I have a h8-1234 HP and I purchased a sapphire 7870 radeon to replace the factory card. I upgraded my PSU to a 650watt Antec, hooked up the graphics card turned the power on. The computer seemed to be booting up normally, however, the display is not coming on. I am certain I have enough power to the card, so it might be my motherboard is not sufficient. Any help would be much appreciated.

  1. What motherboard do you have?

    Check the BIOS settings to make sure that when you replaced the card it isn't trying to use an onboard graphics card instead of the GPU.
  2. The strange thing about this particular model of motherboard is that, there are no on-board graphics.
  3. ok, do you get any video during post? logo screen or anything?
  4. It is difficult, because there is no on-board graphics I can't really troubleshoot without taking the graphics card out and putting the stock card back in. The fans on the graphics card turn on and so forth.
  5. No, display what so ever. The display does one thing, however, it starts to tell me to check the connection to the card because there is no signal
  6. Best answer
    I would suggest powering down, and reseating the graphics card. It might be that it is not fully seated in the PCIeX slot.

    If that doesn't work I would suggest contacting the manufacturer's technical support and considering an RMA.
  7. I know that the motherboard has a pci e slot 2.0 and i believe I read on the specs for the sapphire it requires v3.0. Do you know if that may be the problem, and is the radeon backwards compatable?

    You can run a 3.0 compatible card in a 2.0 slot just fine. I would contact the manufacturer of the card. You might have received a bad one.
  9. I am going to put the card into my friends computer. He has the same type of graphics card as the one I recently purchased. I will post the results.
  10. I tried the graphics card in my buddies computer, and it worked just fine. So, I know the card works well enough.
  11. If you put the original card for your PC back in, does it work again?
