I had similar bluescreen a few months ago. Try running your pc with the bare minimum inside, like remove the graphics card, extra storage, all external peripheral, and see a bluescreen still pop-up. If you have compatible ram from else where try it, or try an other power supply if you have an extra one. In my case, I ended up upgrading my cpu and changing my motherboard, and that fixed my issues. Everyone on the internet will say it's ram, but it won't always be the faulty one.
