  1. Interrupt sistema uses 100% of CPU until I open task manager


    If my pc is slow I obviously go to check in task manager and I saw that when I open it there's always interrupt sistema that uses 100% of my CPU than, after 4/5 seconds it disappears. What can I do? Interrupt sistema uses 100% of CPU until I open task manager 17edd521-c0bc-4b01-a49a-f40faf350205?upload=true.png

  2. Cpu usage high until I open task manager

    So, whenever I open my task manager CPU usage is at 100% and thing that takes up 100% is something called " system interrupts ", but its only when I open the task manager, so when my task manager is closed my CPU usage is at 100% at all the times? Do
    I need to keep my task manager open to play games?...

  3. CPU at 100% that goes away when opening Task Manager

    Thanks for your answer @Jay#222. I understand that a computer is doing a lot in the background. In that case above, I was using Adobe Lightroom which is heavy on the CPU but I might get this when I'm just using Google Chrome googling things. Its weird to
    me because upon opening the Task Manager, my CPU calms down when it might have been working hard for quite some time. My CPU might be working hard for 10 minutes and then upon opening Task Manager, it calms down. I'm sure if it listed the CPU usage prior to
    opening the Task Manager, it would be 90%-100% usage all prior. Is it something like the Task Manager flushes processes and that's why it drop significantly? And I mean it drops to the point where the fan will calm down and my laptop will not lag much.

  4. Interrupt sistema uses 100% of CPU until I open task manager

    System Interrupts using 30 - 100% CPU

    My brand new laptop keeps running extremely slow and task manager says system interrupts is using up most of my CPU. I've looked online and it says to update windows and drivers which I have done and nothing happens. I've contacted customer service but
    its so bad that the automated chatbot doesn't even reply and when I call to speak to a real person they say nothing to help. Surely system interrupts should not be using 100% CPU?
