BSOD Issue: VIDEO TDR FAILURE (nvlddmkm.sys)

Hello, as stated in the title, I've been experiencing BSODs for quite a while, most often when I searched for the error code of a BSOD (they were often different) online, the sites often referred to a RAM issue, it seems, and it's true that every time I had a blue screen and after that it was impossible to turn on the computer (for example, 2/3 days ago after a BSOD when I wanted to turn on my pc, the button turned orange and the computer beeped 3 times in a row then nothing and all that in a loop) but all I had to do was remove the RAM sticks, blow on the sticks and the connection plug, replace everything, and the computer would work again. After that, I still had BSODs (most often not long after launching a game) except these BSODs almost always had the same error code which is: VIDEO TDR FAILURE and the failing component: nvlddmkm.sys. I searched everything online, and most sites talked about a graphics driver problem; they proposed solutions to fix it that I tried:

- (yesterday) Install the latest driver offered for my graphics card using the Driver Booster application. [The problem persists.]

- (today) Go to Device Manager to remove my graphics card as well as its driver, restart the computer, then wait for the computer to reinstall everything by itself. [The problem persists.]

- (a few hours ago) Execute in CMD the command: "sfc /scannow" to fix part of the issues related to corrupted files, apparently it detected and removed some, so I launched a game to test and it lagged very slightly, so I enabled the Overclocking mode in the AORUS application of my graphics card, then I activated to test, the function that keeps the fans on all the time, a few seconds after that, another BSOD with the same error code and since that one, when I turn on my computer, it powers on but doesn't send any image to the screen.

Here’s my configuration:

- Nvidia Geforce GTX 1050 ti (Windforce and OC edition)

- Intel Core i5 2500

- Hyper X RAM stick 2x4 gb DDR3 1866

- PSU:

- Unknown motherboard

There, I think I’ve said everything (given the length) so thank you for taking the time to read.
