PC won't boot at all - Radeon 7770

I'm replacing my Nvidia gt 610 with a radeon hd 7770. My PC won't boot with the radeon card connected (fans start etc..) I see no BIOS or anything.

If I take out the radeon card and use onboard or Nvidia graphics, it starts normal. So, I don't know if this is a problem with the graphics card, or my PSU.

Specs:

Intel I3 processor.
650W PSU.
Radeon HD 7770 (I think 450W).
500GB hard drive.
8GB RAM.

  1. Did you uninstall the nvidia drivers before you started your computer with the 7770? If not, try that first and see if that helps.

    The BIOS and Windows don't exactly talk, so I think that's irrelevant whether I have drivers or not. But yes, I've tried uninstalling them.

    **Edit** Just to clarify, when the 7770 is seated and you start the computer, nothing starts at all?

    Your PSU should be more than enough at 650W, so I don't think there is any problem there.
    So the fault most likely falls with the card.

    And this is a random idea, but try starting the computer up with the 7770 seated, but without the 6 pin power connector.

    Yes, there is no display. My computer runs windows as normal, but just no display :(.

    When I turn it on without the power, the LED on the graphics card turns red and gives no display on my screen.

    I'm out of ideas of anything else we can try, but I'm thinking that the card is bad. The only definitive way to check is to put it into another computer if you have access to one.
    Other than that you can try your luck by contacting the card manufacturer or returning it for a replacement/refund.

    Hopefully someone else will have a good idea of where the problem lies and can get a fix for you.

    What completely blows my mind is; my motherboard has a feature that tells me what is connected to my board, it tells me that my Nvidia geforce gt 610 is connected to PCIE slot #1 and my radeon 7770 is connected to slot #2. It doesn't actually display the names like this, it's something like "ATI technologies".

    I'm begging to think it's a power issue.
