While playing Rainbow 6 last weekend, my screen went all black. My computer restarted, but the gpu gave no output anymore. First thing I did was switch the HDMI-cable to the motherboard's hdmi-port. Surprisingly the onboard gpu was already giving output. Considering the fact that the week before I had been struggling to update windows 10 to version 1607, I figured there might have been a relation between both cases. After moving the gpu to the 2nd PCI-e slot there still was no output. I checked the device manager while running on onboard again, I saw the gpu among hidden devices. My thick brain had seen it as a proper action to "uninstall" the device through device manager causing it to be lost forever. Desperate and furious as I was, I had not yet checked the system browser in the eufi to see whether the gpu was actually being detected. After searching every topic with relatable problems, none of the solutions have worked out. I'm afraid the gpu is dead and am not looking forward to an RMA. All the hassle will cost too much time.

What I already have done:
  • - Move gpu to 2nd pci-slot
    - use DDU and reinstall drivers (last time installing the drivers there was no card being detected by the installation software from amd)
    - Insert another gpu (fans are spinning, but I don't know whether there was any output because I haven't got the right cables)
    - Boot without gpu
    - Update BIOS
    - Reinstall windows
    - Remove one RAM-stick
Symptoms on the gpu:
  • - No output
    - Not detected by the motherboard
    - (aesthetic) LED is burning
    - Fans are not spinning (though I don't recall whether the fans were spinning on installation, because this one disables the fans beneath a certain temperature)
Specifications
  • i5 6600K
    ASRock Z170 Extreme4
    Sapphire RX 480 4GB
    16GB Kingston HyperX DDR4 2133MHz
    Samsung 850 EVO 256GB

UPDATE
After running DDU once again the device manager lists Microsoft Basic Display Adapter in PCI-slot 2, which is the slot where the gpu is plugged into. The description of this device shows an error 45, not properly connected.

You may have to RMA. Have you tried a different card, or can you even? How old is this card? If it's less than the time required to allow an RMA from the purchaser, I'd just do that. If it's more, I would call the brand owner and ask for warranty.
