CPU usage jumps to 100% randomly
On my Windows 11 system, the CPU usage randomly spikes to 100% for no apparent reason, even when no applications are running and the PC is completely idle. These sudden spikes cause the entire system to stutter and become unresponsive, and they occur unpredictably throughout the day without any specific trigger or pattern that I can identify.
