Why Does a Computer Freeze? What Happens Inside the CPU When It Crashes

During a computer freeze, the CPU isn’t simply idle; it may be trapped in a high‑priority interrupt handler or deadlocked kernel code, and the operating system’s scheduling and interrupt priorities determine whether the processor can be reclaimed, explaining why a simple infinite loop rarely causes a crash.
