As soon as I start my PC and check Task Manager, I see the percentage of CPU usage at 100%. When I click on the Details tab, I see that idle process is at 93-99%. I know that the idle process runs when there isn't anything demanding working, but I think it's strange for the CPU to be constantly at 100% and full speed.

Also my computer sometimes randomly freezes and crashes... could it be related to the CPU usage?

Specs: (OS: Windows 10)

  • Intel i5 2550k
  • nVidia GTX 770
  • Asrock P67 Pro3
  • Corsair C750M

I have just installed the latest Geforce drivers, and I have no new drivers available for the CPU

    try using "process explorer" to see more details on which process is taking all that cpu time – Magnetic_dud Feb 9 '19 at 16:42

The "System Idle Process" doesn't mean that the CPU is permanently operating at 100% utilisation.

The idle process will mean (unless you have a malware infection masquerading as said process) that the CPU is effectively being put to sleep for that percentage of time.

It is almost certainly unrelated to crashes or freezes.
