It's a really annoying problem, and it's a lot more frequent than I'd like it to be, though I'd rather the problem not exist at all. Someone suggested my computer might be overheating, but I checked the temperatures and they did not increase at all during these moments of random low FPS.
These are my temperatures now with no games or anything special loaded. When I have a game open, the temperature for my cores, as expected, increase, but only by ~5. When my FPS randomly drops, the temperatures are no different. Also, my computer is never hot or anything, albeit my room sometimes warmer than I want it to be. And my computer is also clean on the inside, and no thermal paste seems to need to be applied.
This problem started occurring maybe 3-4 months ago, if not 2-3 months? I've tried everything I can think of, and nothing has worked. I'm probably forgetting to do something, or maybe I just don't know. I've been suggested to reformat, so I might give that a go, but only if it's worth trying. Should I reformat? Well, either way, what should I do/try to fix this problem?
