Alright so about a week or so ago I decided to be a complete fucking retard and put more ram into my motherboard slots that wasn't the same kind of ram I already had installed. The PC would boot up then shut off, so I removed the extra RAM and only went back to my original RAM, but then I ran into a problem.
Ever since then, I've been getting pretty nasty artifacts show up on my desktop/browser/discord (I haven't been on the PC long enough to try to see what happens when I'm playing games.)
It would originally start with my computer loading into a completely black (or sometimes light blue) screen where my PC would be completely frozen and I'd almost never be able to get onto the desktop unless I booted into safe mode or plugged my monitor into the integrated graphics port on my motherboard and disabled/uninstalled my Nvidia drivers.
There would be rare times when my PC would actually make it to the desktop without me having to do anything, but then after the desktop loaded things would glitch and I'd start to see artifacts and then the PC screen would just go black and freeze like before.
I ended up resetting the CMOS by taking the motherboard battery out and placing it back in, and that seemed to help a significant amount, but the problem still persists to a degree.
Now I can load to my desktop without issue every time, and things will appear to be stable, but it will almost always artifact either 10-20 minutes later, although the PC will never freeze anymore.
This is what it looks like when I have chrome open and it decides to artifact. (Thats not my help question, I was just on that page while searching for a solution)
Those little colored pixels on the bottom right blue image show up on my desktop and tab windows when I'm browsing files too. This never happens when I load into bios or start the PC up and only happens after I've loaded the desktop and am making use of my graphics card. It's not like any other kind of artifacting pattern I've seen when searching google, so I don't know how to properly diagnose what the problem is.
So did I somehow fry my graphics card by putting RAM in wrong or is this some other problem? If I had to guess myself I'd say my VRAM went bad somehow from putting the other RAM stick in and it just ended up frying the card, but I honestly have no actual idea and I'd like to know what the problem is before I go out and get other graphics card only to find that this problem would keep happening.
For reference, I've never overclocked the card before and I've only had it for about 3 years, so I know overclocking it isn't the problem, and I've also done a memory test and both my RAM sticks read without issues. Either way, I'd really appreciate some help diagnosing what the problem specifically is as I'd love to start using my gaming PC again cuz I can barely stand playing on this worse rig.
