New Build; My computer isn't recognizing that I have a graphics card installed, even though the gpu is getting power.

So recently, I built my very first pc. I was excited to start playing when I found out that my computer didn't recognize my graphics card. I have an ASUS Geforce GTX 1070 turbo that is brand new. I have tried a lot and nothing worked. I connected my hdmi port to the card, got no signal. I reseated the card itself and lightly cleaned the pins with an eraser, and that didn't help. It doesn't show up in the device manager, even with hidden devices turned on. It's like it thinks nothing is plugged into the PCI-E slot. I really need help because this is my first time and I'm afraid I did something wrong.

Specs:
CPU: Intel Core i5-7500 3.4GHz
Motherboard: Gigabyte GA-B250M-DS3H micro atx
RAM: Team Dark 16GB DDR4
HDD: Hitachi Ultrastar 2TB 3.5" Drive
GPU: ASUS GeForce GTX 1070 turbo
PSU: Seasonic 520W 80+ Bronze
Case: Deepcool Dukase V2

I'm also sure it's not incompatibility, because pcpartpicker said that all of those parts were compatible

    I have. I've reseated the card 3 times and I've replugged all the power cables again. None of that has worked.

    No, I wish. My mobo is a micro atx so it only has one PCI-E slot.

  7. Do the graphics card fans spin at all when turned on?

    Yes, the fans spin, the backlight on the gpu lights up, and the small light by the power slot lights up.

  9. Connect video input on the monitor to the output of the motherboard. Boot. Head into BIOS/UEFI setup by pressing 'Del', 'Esc', or some other key. Refer to your motherboard's manufacturer for the required key to press.

    Next, find the option to change the 'primary video device' or however it's termed. Again, refer to your motherboard manufacturer's manual for this setting.
    Change it to the external GPU.

    Save and exit, then turn OFF the computer. Plug the video cable coming from the monitor into the GPU. Boot.

  10. So it seems like the graphics card works, so I have a feeling it is the PCI slot on your mobo. If theres any way you can verify that by trying the card on another board or trying another device in the PCI slot that would be helpful. If your able to figure out which part is the issue, i would imagine you could get a replacment.

    Thank you, I'll try this as soon as I can get a dvi adapter. I've heard that sometimes the hdmi port arrives dead on the card I have.

  12. Does your motherboard have an HDMI connector?

    It does, but if I plug the HDMI cable into the motherboard my monitor gets a signal, but it doesn't recognize the card.

  14. You want the monitor to get a signal. Plug the monitor into the motherboard, and follow the instructions above.

    Well, my PCI-E slot is already set to boot before the integrated graphics. I can't plug my video cable from my monitor into my GPU because my GPU doesn't have working HDMI ports.
