    CPU high usage until i open task manager


    I have been looking for this for quite some days. I have a Lenovo Legion Y720 laptop and whenever it's on, the fans will go crazy at all times, even when i have all the apps closed. But this all changes as soon as i open task manager, because when i do a can see the system is running with 100% CPU usage but after half a second it goes down to normal levels and the computers starts to work normally.

    I have my suspicious that it might be some kind of virus or something else. What kind of software can i run in order to get rid of this problem?

    :)

  2. Task Manager High CPU Usage

    I have the same problem myself with it only happens when I scroll through task manager and open and close it. I don't know this for sure but the reason this probably happens is that you may have a lot of processes running and task manager is using a lot
    of the CPU to process the usage of each program.

    What I have done is disable data that I don't need to see like network usage and GPU usage and it drops the CPU usage a bit. I have also enabled everything and scrolled up and down on it and task manager uses almost twice as much.

    I would suggest disabling everything but CPU, disk, and RAM, (I would not suggest having GPU on because it is almost always at 99% unless you have FPS limits).

  3. High CPU usage when opening task manager

    Hey, so as said in the title, my CPU usage is unusually high when I open task manager. After about a second, the CPU usage starts dropping down to around 5%. I've ran malwarebytes multiple times, but the issue still persists. I would like to avoid resetting
    my PC if possible.
