Hard to say, you might want to start by downloading and running MemTest86 for USB or CD and booting from it, let it run at least one full RAM test. In 30+ years I've only once ever found an actualy memory problem, but the time it was there I really appreciated being ablke to find it so easily.

I sort of doubt it's actually a bad stick of RAM, but MemTest86 is always worth a try if you suspect one.

That error is generally tied to hardware drivers most of times I've seen it. A quick check that you have the latest BIOS/UEFI, chipset and assorted mobo drivers up to date might be worth a look. Cleaning with DDU in safe mode and reinstalling the GPU driver fresh might also be worth a try.

Without the minidump from the BSOD, I can't really tell you what exactly is causing it because it's a pretty vague error with a lot of possible causes.
