Problem with artifacts, nvlddmkm Event 14 / nvlddmkm Event 153

I apologize for the wall text, but the problem is a bit complicated.

I'm dealing with an issue that’s really irritating me. It happens out of nowhere — sometimes the system just “corrupts” and a bunch of artifacts appear on the screen. I removed the drivers using DDU and reinstalled them, but it didn’t fix the issue. I cleaned the PCIe slot as well, but that didn’t help either.

(In the video I hit the desk harder to show the problem, but it happens randomly, without any prior warning.)

And besides the artifacts, I'm having another problem where my computer simply shuts off. As soon as I open CS2, when it finds a match and starts loading the map, the computer just turns off. When I check the Windows logs, the following errors appear:

Unable to find the description for Event ID 14 from the source "nvlddmkm". The component that raises this event is not installed on the local computer or the installation is damaged. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

The resource is present, but the message was not found in the message table.

I suspect it might be related to the power supply, because a friend of mine had a similar problem, and in his case the PSU was faulty, which eventually damaged his RAM slot — something that’s also happening to me. My A2 slot is not working, and I’m thinking the GPU slot might also be defective.

If anyone knows how to fix this or can help me, I would REALLY appreciate it!
