    Terminal showing Windows 10 CPU constantly at max 100%


    Hi,


    I've been searching the forums to find a solution to my problem - my CPU is always running at 100%. It's strange because I've never not seen my CPU run at 100% it's always at 100%. If I close any program, then others supposedly instantly absorb the freed up CPU.


    I can close everything heavyweight. If I do so, then I end up with a long list of maybe 100 standard processes that reportedly each use 0% cpu. Yet, my total cpu reads as 100%.


    It seems to be a glitch with task manager reading the CPU. But just to cover all fields: Superfetch is disabled and my power management is set to balanced.


    Cheers

    :)

    Overclock cpu max frequency constantly changing in task manager

    Hi,

    I'm overclocking my Intel 8700k to 5Ghz and every time I check the current frequency in task manager the max is constantly changing. I have high-performance power settings on windows enabled and I have also disabled CPU state and Intel SpeedStep in the BIOS.
    I also noticed that when using other tools to display my GPU and CPU performance they show my CPU max frequency is exactly 5Ghz, why does Task Manager constantly display a constantly changing frequency?

    Any suggestions?

    Much appreciated

    CPU constantly at 100%

    Being as stubborn as I am for Windows 7, I waited until the last possible second to upgrade to Windows 10. Now that I've upgraded, my CPU is constantly at or near 100% mainly by two processes listed as System and System Interrupts, both running 20-30% each. I looked around and most people say these shouldn't be more than 5-10%.

    Before you start suggesting the obvious like checking for updates, flashing BIOS, upgrading drivers, editing Registry, using Process Explorer, going into device manager, checking background apps, using the built in troubleshooters, formatting, erasing previous Win installations, etc. Let me just say, that I've tried all of those and none of them seemed to work. I can get the CPU down to about 50-60% but that still seems like quite a lot for a freshly booted up PC just sitting on standby.

    At this point, I'm looking for any suggestions at all. My best guess is that maybe my laptops just too old? I've had it for close to 5-6 years or so and I never replaced any of the parts, so it may just be that it's just getting harder to run modern OS? I don't know. If there's any other options, I'd love to hear them before I start looking into replacements.

    Windows 10 extreme CPU usage

    Thanks, but yes I was definitely seeing this issue while that trace was recorded.

    Task manager was constantly showing 100% CPU usage and Resource monitor shows silly numbers for the CPU usage (40441489%).

    If I sum the numbers under CPU in the Processes tab in Resource monitor, it matches the values shown in the trace (i.e., CPU usage is not 100%, but the charts and summary total at the top of the processes tab are maxed out.

    In task manager the CPU usage numbers seem to be normalised to 100%.

    i.e. they are constantly changing but seem to always add up to 100%.

    I think that the CPU usage reported in the trace is correct, but Task Manager and Resource monitor are doing something wrong?
