    'System' process high CPU usage


    Since the past 3-4 days the process called 'System' has been constantly using approximately 35% of my CPU. The usage is pretty much constant all the time. Below you can find screenshots from task manager, resource monitor and process explorer.
    In the past I've never seen this, leaving the PC idle dropped the usage down to almost zero, now the CPU is running at full clock 24/7, heating it up ~55C, which is mildly undesirable.

    Attempts done so far to fix the issue, none has worked:
    - Waiting. I leave the PC to run overnight, but it does not seem to help it.
    - Restarting, done multiple times, no effect whatsoever.
    - sfc /scannow, nothing found.
    - Full virus scan, nothing found.
    - The update settings has been set already to not to receive from other pc's. All updates are installed what windows update has to offer.

    PC specs:
    Acer VN7 laptop, running Win 10 Home 64bit. HW: i5-6300HQ, 16GB, GTX960M. All drivers up to date.

    Hi, you'll need to do some analysis e.g.
    High CPU utilization by process

    You can also try a process of elimination - does this happen after a clean boot/in safe mode?
    If you can find a situation when it does not occur you may be able to work from there.
