Cannot solve pc hardware issue and don’t know what to do. (Games and programs crashing)

I started having an issue where the games I play would crash, always showing an error related to memory. The most common error is EXCEPTION_ACCESS_VIOLATION which I’ve seen on chrome, icue, Minecraft, world of Warcraft. It would do it a few times and then run normally for weeks, but now it started doing it every 15 minutes on any app I have open. Otherwise my pc runs normally.

Since I think this is a memory error, I ran memtest86 off of a usb and it came back with no issues. I also reseated my ram and tried my ram in different slots. When none of those things worked, I also tried clean installing all of my drivers, factory reset windows, and updating my bios firmware. I still get the crashes.

I read online that this could just be my CPU dying. I would be happy to buy a new CPU if I knew it would fix the issue, but I have no idea if that’s the problem. How can I troubleshoot this?
