  1. Why is my cpu alway at 100% even when system idle process takes up 99%?


    My cpu is alway running at 100% since yesterday, I tried closing all app except task manager to see if it was that but it was still running at 100%. Afterward I ran an antivirus scan with kaspersky and it found nothing wrong with my pc. I also tried going into BIOS and enabled AMD cool and quiet since some people said it might help out but in the end it didnt. I searched for driver update and found nothing wrong with them. The strange thing is only task manager says that my cpu is being used at 100%, other application I have says it's being used normally. I saw some other post talking about going in msconfig.exe and stopping everything on startup but that didn't work either.

    Task manager saying 100% cpu:

    System idle process is using 99% of it:

    my AMD software is saying it's not even being used at 10%:

  2. CPU Usage 100% and idle process is 100%

    My CPU usage shows permanently 100% in task manager (in "Processes" tab) even my system idle process (in "Details" tab) is almost 100% and the CPU runs hot - fan is permanently on - CPU speed (in "Performance" tab) is always a bit above maximum speed!!!

  3. System Idle Process CPU Allocation?

    Hi,

    I am Sumit, an Independent advisor and a Microsoft MVP here to help.

    System Idle Process, as the name suggests is a process that indicates CPU is idle and is not being used, aka is at rest. This is done to totalize CPU usage to 100 between the processes.

    So you do not have to worry about anything.

    System Idle Process High CPU Usage

    The system idle process tells you for how much of the time the CPU is twiddling its thumbs. The higher the figure, the better! A totally idle CPU would show 100% for the system idle process.
