system high CPU while Idle Process < 10% and no tasks running
Posted on 2010-11-10
How do I determine what is using CPU resources, when nothing appears to be running? There are no applications running. I have Windows Task Manager open. Typically, the System Idle Process is using close to 100% of the CPU. Now, the System Idle Process is at 9% and System is at 91% CPU usage.
It is strange to me how Firefox can be very responsive, so it must have higher priority than the system process, which consumes most of the CPU when I stop typing this. How do I figure out, which process is using the CPU. Mem Usage is only 240K for the System process under User Name SYSTEM.
The OS is Windows XP SP3 with all of the critical updates applied.
