Computer (BIOS) don't find VIDEO CARD

Hello everyone! I built first computer and now i have one trouble.

My computer main components:

- MSI Z270 GAMING M5 s1151
- INTEL I7-7700K
- GIGABITE GTX 1080 AORUS

- ATX 1000 Вт Cooler Master RSA00-AFBAG1-EU
- DDR4 16 gb KINGSTON HYPER X
- Deepcool ASSASSIN II

My PC don't see (find) GPU. I read most of topic about this trouble.
So, i installed Windows, through display port from motherboard. PC see all components besides GPU GTX 1080.
Windows don't see GPU, BIOS don't see GPU. Fans on GPU spin and it glows.

I tried
1. Reinstall GPU, Install it in 16x PCI-E and in 8x PCI-E.
2. Variations of connectivity with PSU (GPU have 2 8-pin). Now I'm connected via GPU-PSU like twice by 8-6 .
3. NVIDIA driver utility don't see GPU, can't find devices.
4. In BIOS in Integrated Graphics Configuration i have Initiate Graphic Adapter = PEG

I can try 4x PCI, but i think this is not problem. Try update BIOS? Good idea? I have penultimate version (watch in MSI site).
Can you help me? What first of all i should do? Or GPU is broken?
Thank you for help!

More about bios detect gpu
  1. So you have version 7A78v18 on your BIOS? You may want to breadboard the system and see if the GPU is being fed any power. You might also want to see if removing the CMOS battery for 15 minutes before replacing it changes anything.

  2. All products can be defective on delivery. I think a bad graphics card is most likely.

    When you install the gpu, make certain it is securely inserted in the pcie slot along the entire length.
    This is likely ok since you get lights and fans.
    Make certain that your psu power leads are correctly and fully inserted in both ends, and that you are using the proper cables.

    If you can, test with some graphics card in the first X16 slot to see if the slot is ok and can be detected.
    If a different card is not detected, the motherboard is likely defective.

    I would not try to update the bios unless the update will explicitly address your problem.

    Hello!
    I have version BIOS 1.7 (Live Update 6 say it). I understand it is 7A78v17, right?
    I removed battery for 15 minutes now. Let's wait 15 min, then i will write something.
    Thanks for help.

  4. In the bios, there should be an option to enable the discrete graphics card.
    It may not be enabled by default unless there is also a monitor attached.

    Hello!
    GPU securely inserted, but GPU card can move perpendicular to the slot. for example because of its weight, when i fix it by bolts, then it not can't move.
    I use 2 cables like (8,8) --------- 6.
    So 6-pin in PSU then end cable like pair (8,8), i insert 8 pin in GPU, another 8 pin in air. And another cable 6-(8,8) just like another.
    I can't try testing another motherboard or GPU, because it's new PC, i have only Laptop.

    Thanks for help.

    Now working. BIOS and Windows don't see GPU.

    I have this
    4. In BIOS in Integrated Graphics Configuration i have Initiate Graphic Adapter = PEG

    Also i always have cable dispay port inserted into motherboard (if into GPU monitor say no signal)

  8. Also additional information!
    When i installed drivers from CD for MSI motherboard were problem: i can't install Intel ME drivers from CD (it go to 99% and nothing). then i saw that i have some devices with name PCI with yellow sign "!" in device Manager.
    I go to official site and install Intel Me drivers, now i don't have devices with yellow "!" in device Manager.
    Maybe some trouble with PCI drivers were and remained?

  9. Hello Guys!

    I took GPU to the technical center, they said everything ok, then i took motherboard, answer - it's ok.
    WTF?
    If GPU and motherboard are ok, what it can be?
    Some people say that mb it's PSU problem: PSU can't give enough energy, cables for GPU are bad. But i think BIOS should see GPU anyway.

    I DON'T KNOW WTF:(

    Could you explain what you mean by that? If GPU has two 8-pin slots, there is only one correct way to connect it to PSU - using two 8-pin (or 6+2 pin - in this case all 8 pins must be connected) plugs. If you connect it any other way, the card most likely will not start at all.

    All my 8 pin in cables - it is 6+2 pin.
