Question New pc stutters and unstable fps

Dec 1, 2020
So recently bought new pc, it was running fine for like a week but now fps fluctuates a lot. cant play other games, coz i get so much stuttering and fps is much lower than it should be. for example in black desert online, when i afk fps is 170, but when i start to use abilities it stutters and fps drops to 100. In apex fps can randomly go from 270 to 160.
