Graphics card won't give video output

[Like A Tomato]

How it started: Whilst playing a game i suddenly got a black screen

Fixes i already tried: drivers update, DDU, windows reinstall (win 10)

"Symptoms":

1. If monitor connected to GPU: video card will give video output until you get to the windows password screen, then it will black screen. after a few boots like this, it will suddenly be able to get to the passowrd screen whilst still being connected to GPU

2. Computer WON'T boot to safe mode with GPU installed (even if video output connected to motherboard), i discovered it when i tried to boot to safe mode to use DDU

3. After using DDU computer seemed to work fine until the .exe file for GeForce experience got downloaded (because of DDU there were no GPU drivers installed), and it black screened before running the .exe file

4. IMPORTANT NOTE: The GPU has never turned off, it has just stopped giving video output (aka black screen)

 

(Also,  computer has integrated graphics from intel CPU)

 

Edit: device manager gives error code 43 for the GPU

You can try reseating the GPU, could be a bad PCIe connection.
