  1. High CPU usage and taskbar flickering when I view a folder containing PNG files


    I recently received a brand new Dell Latitude 5400 laptop at work which runs Windows 10 Pro x64, and I have noticed that every time I open or view a folder which contains any *.PNG image files, the taskbar icons begin to flash every second or so and I can see the CPU usage drastically increase in Task Manager for Explorer.exe. This happens whether I'm launching a file picker dialog box in a browser or other application, or directly opening a folder in File Explorer.


    If there's even one file with a *.PNG extension, the CPU usage jumps from <10% to >60%, along with the other symptoms I mentioned. The symptoms do not occur for any other image file extension, such as JPG, GIF, BMP, or TIF.


    I have spent several hours searching online for possible solutions and I've tried multiple troubleshooting steps, including:


    -Updating Windows

    -Restarting PC

    -Running System File Checker

    -Scanning entire PC with MalwareBytes (no issues/threats detected)


    ----------------

    System Specs:

    CPU: Intel(R) Core(TM) i7-8665U CPU @ 1.90GHz, 2112 Mhz, 4 Core(s), 8 Logical Processor(s)

    GPU: Intel(R) UHD Graphics 620

    OS: Windows Pro 10.0.18362 Build 18362, 64-bits

    "COM Surrogate" uses high CPU.

    Hi,

    After opening any folder containing video files "COM Surrogate" process starts using high CPU around 30% (core-i3 3.10GHz). Than the folder containing video files stop generating
    thumbnails and also in Taskbar application icon being disappeared.

    Please, any suggestion...

    Thanks!

    Screen Flickering on AC Power - Windows 10

    Hi Greg,

    I went through the listed steps. I previously did full reinstall of Windows 2 days ago hoping that would help.

    The screen does still flicker. I believe to have narrowed down the remaining cause to sudden and high CPU usage from the 'Services and Controller App' listed in the task manager. When CPU quickly peaks from this the screen flickers still.

    Similar to this question:

    Services and Controller app Random High CPU usage.

  4. High CPU usage and taskbar flickering when I view a folder containing PNG files

    high cpu usage

    After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
    programs and find no viruses. Any suggestions? Thanks.
