They're not screws, they're rivets. They're "permament" fasteners used to assemble cases. You can remove them, but you have to dril them out meaning you destroy the rivit and would have to put in your own if you wanted to reattach it.
Your motherboard should be fine btw. If I were you, I might try a 3600 and just see how it goes. Eventually you could do RAM too, but if you're happy and the fps instability is better, then that's all that matters. Don't get too caught up in buying new stuff all the time; enjoy it! You could eventually get a new monitor, but you'll still have trouble getting anywhere close to 144 fps in a lot of games. Personally I use an ultrawide 34" that runs at 100hz. Besides the bluriness that VA panels naturally have, it's pretty good, and great for movies, too.
