I’m not very tech savvy so please bear with me.

I bought a premade in 2018 and I’ve only updated the graphics card and ram since then. I’m using a 55" Samsung TV as a monitor. It’s really starting to get sluggish/finicky. Gaming example: it can run BGate3 on medium but starts having issues any higher.
