  1. Disable the onboard graphics card and enable the PCIe one in the BIOS, seems like thats your problem

    Thanks allot for the quick response. Unfortunately you are speaking a language I don't get. Is there a simple way to do this?

    - not sure how to disable
    - not sure what PCIe is
    - not sure what BIOS is

    Any help is appreciated.

    Thanks again.
  3. When you first press the power button, spam the 'delete' key until something comes up. Go through the options of the whole interface and find something called "integrated video" or something similar, disable this. Or there may be something like "video adapter" which allows you to choose what GPU to use, select the one that says "PCIe" or something like that. What you find will probably be different, varies with BIOS you see
  4. What kind of motherboard. Many of the newer motherboards with integrated video sense the presence of a video card and automatically deactivate the onboard video.

    - Not sure what spam the delete key means but when I powered the computer on I tried holding the delete key down and pressing the delete key up/down, up/down while it booted up. Nothing happened.
    - I inserted the new video card in case I reached a point where I could disable the onboard video and activate the new one, but I got the original error message "no video input signal". This is confusing because the new card was in the machine but the vga cable was connected to the onboard connection????

    Not sure what kind of motherboard it is. The computer is a HP Pavillion m7580n.
