    ACPI.sys using 30% CPU


    The process system is constantly taking 20% to 30% of my CPU.

    I've checked with the Process Explorer, it indicates that the cpu is taken by ACPI.sys.

    I've tried most of the solutions I could find with no success.


    Now, I've basically reinstalled this machine from scratch because of the issue but even after a clean re-setup the issue hasn't gone away.

    The weirdest part of this is that if I put the computer to sleep and then wake it up, the System process goes back to a normal CPU usage but if I restart the computer then it's back to square one with ACPI.sys going over 30% CPU


    How can I fix this?

    :)

    ACPI.sys using 30% CPU

    Thanks for the quick reply.

    Yes the issue persists after a clean boot and also after a computer reset.

    The CPU usage of ACPI also drops after a sleep/wake up of the computer.

    The temperatures are all between 30°C and 40°C for the CPU, GPU and HDD.

    CPU Usage Stuck at 30%

    I'm sorry but there are no background process using 30% of cpu. The highest one is Microsoft Software Protection Platform, using 7% of cpu. The other one is Explorer, using 3% of cpu.

    Should i disable it?

    That is 10%. So there is another 20% being used somewhere and it must show in details tab using more details on bottom to show all processes. It has been this way from day one of Windows OS's. Or maybe there is malware or a virus. But it still should show
    CPU usage and items combined will equal the total CPU usage.
