I've just build a brand new pc. And after installing windows and the rest of the drivers i realised that in device manager my GPU was not detected.

So i replugged it several times and changed the splt but the results werw the same.

When i tried installing nvidia driver it said no compatible graphics hardware is detected.

The GOU is connected to the PSu, the fans are spinning and the lights are on.

any help would be appreciated.

System specs:
i7-8700K, 3.7GHz
Cooler CPU Noctua NH-U9B SE2
Corsair 32GB (2x16GB), DDR4, 3200 MHz
Samsung 960 EVO, 500GB, M.2 ssd
windows 10 home

all the hardware is brand new.

Take the cover/fans off and baked just the PCB for 8 mins at 160c, then leave it to cool slowly.
There is no danger to the card at these temps and will not effect RMA unless there is void stickers. (You can go as low as 120c rly but i found 160c 8mins the best)

If you can RMA the card and don't like fixing things, then send it back A.S.A.P sir. I think this issue is a stuck switch/switches in the GPU die, heat shocking them causes it to reset its position. Fixed a ton of cards this way and they all stopped showing in the device manager

Method 1: Show Hidden Devices and Reinstall Graphics Driver

1. Open Command Prompt as administrator.

2. In Command Prompt, type set devmgr_show_nonpresent_devices=1, and then press Enter.

3. At the same Command Prompt, type start devmgmt.msc, and then press Enter. This is to open Device Manager window.

4. Once Device Manager windows opens, click the View menu and select Show hidden devices from the drop-down menu. After that, Any devices that are not connected to the computer will be shown, including the NVIDIA Graphics card.

5. Uninstall each instance of the NVIDIA card and unknown device (The unknown device will be listed under category Other devices. ).

To uninstall the device, right-click on the device name and select Uninstall from the context menu. Following screen shot is for your reference.

Note: NVIDIA graphics card may not be shown as its own device name. It could be unknown device, video controllers, etc. If you are not sure how to identify it, just uninstall the device that has a yellow mark on it.

6. After uninstall, restart your computer then Windows will reinstall the driver automatically.

If the problem persists, it’s suggested that you update the driver to the latest version. If you don’t have time, patience or computer skills to update the driver manually, you can do it automatically with Driver Easy. It’s a tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs.

To update your drivers with Driver Easy, just click the Scan Now button, then when it lists the drivers you need to update, click Update. The correct drivers will be downloaded, and you can install them – either manually through Windows or all automatically with Driver Easy Pro.

(Method 1 would work in most cases. If it doesn’t work for you, try the rest methods.)

Method 2: Restore BIOS to Default

If you are advanced computer user, you may already know how to enter BIOS and restore it to default. If not, contact your PC manufacturer or technician who you could ask for assistance to help with this, as modifying BIOS settings incorrectly can cause serious problem.

Method 3: Update BIOS

You can go to the motherboard manufacturer’s website or PC manufacturer’s website to check for and download the latest BIOS version that you can update to. Contact your PC manufacturer or technician who you could ask for assistance to help with this, as updating BIOS incorrectly can cause serious problem.

(Hopefully these methods help you!)

For it to recognize and use the GPU the monitor must be connected to the GPU. Which GPU, Monitor do you have & how is it connected?

GPU: zotac geforce gtx 1080 amp extreme

they are not connected in any way
the motherboard is connected trough a hdmi cable to the monitor and that's it

Connect the 1080 to the LG 4K via HDMI or Displayport (do this while the system is off), then turn on the system.

When you do this don't have anything connected from the monitor to the motherboard.

Reseat the GPU in the PCIE slot to make sure it's connected correctly and I'd double check your PSU connections to it. If this doesn't work then it could be a defective GPU.

I would not recommend putting a $500 GPU into the oven, especially when it's under warranty. If the card is the issue then your better off doing a RMA.
