    High CPU usage


    Hello, I've been having an on-going problem with My CPU usage spiking up to 55-100% while just browsing the internet and up to around 80ish while just leaving task manager closed and opening it up to notice it was around 80ish before dropping back down.. it's very noticeable when it happens.. especially while gaming.. i get a noticeable frame rate drop and I've tried everything out of the book to solve it.

    I've disabled Hyper V completely as I heard it could caused issues along with changing my power settings to high performance.. made little to no difference at all.. unparking my cores didn't really make a different either or turning off hyper threading..
    I will attach my temps and processes while just browsing and while gaming to see the differences.. both ways My CPU usage is extremely high but my temps are normal.

    Thank You.

    I'm not understanding what you are wanting?.. like what do i use to get what you want to see? that would clear it up more for me.

    We need to find out, which process is causing high CPU usage to be dealt with.

    According to that picture, you are running lots more than just desktop and browser at same time and that list shows only about 1/3 of all the processes. Check your Startup in Task manager and stop everything not really need at startup.

    any ideas?.. I've done the tweaks of disabling unnecessary programs from starting up and I've followed Black Viper's Windows 8.1 services guide and disabled services that aren't needed to be enabled, I've unparked cores/disable HT/Turbo boost.. no luck. still high CPU usage when opening task manager.. I've noticed that service host: Local System uses a lot of the CPU along with my web browser when used with only like two tabs open.

    is this normal activity? I've ran Malwarebytes and Spybot and no viruses/Malware has been found.
    the only programs I normally have open would be firefox and TeamSpeak 3 and task manager just shows my CPU usage sky rocketing up to 85-100% instantly .. it's very noticeable.. especially while gaming and I am about 90% sure this is why I get frame rate drops while gaming.
    any solutions would be great.
