If your cpu goes bad it does not get slow unless it thinks it is getting too hot, the machine will generally crash with a bad cpu. . cpu #2 being 100% is not a problem, but you need output from "top" such that we can see what process it is, ps will not show that as it shows % since it was started. If the process is Xorg or whatever wayland uses then that would indicate that some process is telling the graphics server to do operations and that work is getting in the way of real work. I have had firefox on windows in the last few weeks suddenly get horrible slow (and even takes 30-90 seconds or more to finish exiting after it disappears from the display-still visible in task manager for a while) and I have to restart it to get it to work, but I have not seen similar behavior on linux. And it goes working fine to almost not responding at all.
