  1. Why is my CPU usage at 100%?


    For the past few days, i have noticed my CPU is being used fully. I have restarted my pc multiple times, performed many virus checks with windows quick scan and full scan and with malwerbytes but no viruses have been found. No process is using 100% but my cpu temp is at 75 degrees at 4.7ghz. I am running windows 10 and have an i7-10700k. This started around the same time i started building an app with Expo Go so maybe a package i installed is causing this? Any help would be very much appreciated

    :)

    cpu usage at 100%

    CPU usage at 100% from start up for no apparently good reason. Service Host appears to be the problem but I cant narrow it down more than that at present.

    Any suggestions?

    I am using Windows 10 full release version 64 bit.

    Hi up there : You can find down here. A list of solutions

    that may help. To lower the CPU's high % usage

    -- These solutions apply to Wins 10 : if you report what OS do you

    run and the PC specifications. We can provide other fixes for it

    High CPU usage is often connected to long loading times, sluggish

    performance, and unexpected crashes. Task Manager's Performance tab

    shows detailed information about CPU usage. Older computers may

    not have the appropriate drivers for optimal performance.

    Updating these may fix the problem.

    ** mod note: The following information is copied from https://recoverit.wondershare.com/computer-problems/cpu-at-100.html **
