    "System" process increases CPU usage when PC is idle or locked


    Hello there. I have had this nagging issue that's been ongoing for months now and I can't seem to find a reason why it's happening. It happens pretty much all the time and I can almost reproduce it on demand by either letting my PC sit idle on the desktop for a few minutes, or locking the computer and waiting for the monitors to go into sleep mode. I noticed this issue because I can hear my fan speeds ramp up whenever it's happening, and my CPU temps also rise. My CPU usually idles at around 30-32 Celsius which is normal, but whenever this "system" process starts eating my CPU it will go up to

    System Idle Process High cpu usage

    No, System Idle Process is *not* causing high cpu usage. It's not causing anything at all.

    System Idle Process is not really any process at all. It's just a number inserted to make the total CPU usage add up to 100%. From the little information you've provided, I can't tell what your problem is, but it's definitely not System Idle Process .

    CPU usage 100% but system idle process says otherwise

    Hello, So I was copying a large group of files (400 gigs) to an external drive, it was about 150 gigs in when the PC crashed ( i believe due to MSI usb speed up), i've since removed the MSI program but CPU usage stays at 100% from the moment the PC turns on, however system idle process shows it's using most everything which is good, and PC perfomance is normal and unlike if CPU usage was actually 100%, but I can't figure out how to fix this, any suggestions or tips would be so helpful, I've attached screen shots showing 100% usage but every program running doesn't add up to near that and system idle showing everything mostly idle. Thanks!!!!!

    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.
