High CPU Usage of the System Process

Travis Windows Intelppm, Kernrate, Sysinternals 2

If you have high CPU usage of the System process, this article will help you to track down the offending driver or kernel module.

Intelppm is a Microsoft Intel power management driver for Intel processors that executes in kernel mode (Hence the high CPU of the System process). I tried to use the Process Explorer thread tab on the System process, but since I didn’t have Windbg installed and configured with the Microsoft online symbol server, all I could see was hex.
