  1. CPU is at 100 until I open task manager


    Ever since I uninstalled BitDefender my computer has been acting weird. The biggest issue is even with absolutely nothing open, when I open task manager my cpu usage is at 100 then it drops down to normal levels, around 10-20%. If I close task manager and instantly open it back up, it’s back at 100%. How can I fix this?

    It also takes me about 5 mins of sitting at the login screen after I type my password to actually get into my computer which started happening the exact same time as the cpu problem.

    Windows 10 100% CPU unless task manager is open?

    Yes it does do it in safe mode and the reason I know its 100, because when i open task manager it says 99 or 100 for half a second then shoots back down.

    Opening Task Manager Changes CPU Usage from 100% -> Normal (Windows 10). [SOLVED]

    I could maybe buy that the processor might spike to 100% for a moment while opening task manager. But that still doesn't explain why the processor is running at 100%
    before I open it. Mind that the computer is just idle. If I leave task manager open my CPU never goes over 5% while idle which definitively shows that having task manager open is preventing the CPU from going over.

  4. CPU is at 100 until I open task manager

    Why does task manager say that CPU is 100%?

    No tasks are running, yet why does task manager say that CPU is 100%?
