Conversely, another computer might reach 95% CPU usage within minutes without any noticeable slowdown. At first glance, these situations seem contradictory. Shouldn’t higher CPU usage imply slower system responsiveness? In reality, CPU usage tells only part…

Diagnosing the issue can be difficult when a processor runs at full speed under heavy load but gradually slows down while the workload remains constant. The hardware might not be faulty, the operating system may be functioning correctly, and the program itself may remain unchanged. This occurs because the processor has reached its temperature limit…
