Is my GPU failing? Pixelated black areas

Hi everyone,

Recently I've been experiencing issues on my PC, where videos and sometimes images on my PC that contain black / dark areas are incredibly pixelated.

Here's an example of 3 images / videos on my screen right now that I took with my phone (May take a while to load):

This started happening a few weeks ago. Here's the steps I've taken so far in my investigation:

I'm uncertain what else to test. My GPU is "MSI - GeForce GTX 970 4GB Twin Frozr V", I've had it for 3 years now. It isn't overclocked, I haven't played games or done any rendering / editing with it for about a year, so it isn't heavily used.

Is there anything else I can check to confirm if it's a software or a hardware problem with the GPU? If you need any other details, let me know and i'l do my best to provide.

    Well if reinstalling the drivers fixed it for a short time I would assume it's a driver issue. I would run DDU while the computer is in safe mode, to properly remove all the display drivers, then do a clean reinstall of the latest drivers. I linked an article on hoe to use DDU properly below.
