  1. Desktop blinking on start up


    Started happening randomly since the last Windows 10 update. But sometimes when I turn on my computer, it loads my desktop with my customized background and taskbar colors. Then starts flashing about half a second black over and over.



    After about 30ish seconds, the image in the background disappears. And I can only see the taskbar blinking.



    And then another 30ish seconds it all goes back to normal and the computer works perfectly fine.

    blinking desktop

    Hi, if you are still around, here is my ? Dell PC Desktop Windows 10. A" blink" started occurring last week. The screen goes blank, I hit the mouse and the screen returns. I thought it was the A/C going on, but it happened today with no A/C other lights
    or appliances going on off at that moment. Do you have a suggestion?

    Blinking/Flashing Icons on Desktop PC

    Hi:

    I am experiencing blinking/flashing of several icons that are located on my Win10-64 Pro desktop PC's screen and icons that are pinned to within the taskbar. The PC is a DELL XPS 8700 desktop. I think my PC has Windows 10 version 1803 installed on 5/19/2018, and am getting updates automatically from Microsoft.

    Observations:
    When booting the PC, after the login screen, it is taking an unusual amount of time to load the "image" part of the desktop icons; the filenames in text appear first and quickly, and then a delay occurs before the icon images are "painted" onto the monitor's screen. I also noticed that while having file manager opened, the same file names blink in the directory structure pane, at the far left. Just now noticed, as I am writing this, that while using Internet Explorer browser, blinking has stopped, taskbar icons have disappeared and replaced with blank, box outlines, no response when clicking on a desktop icon; this happened once before and I had to reboot PC to get control of taskbar back.

    What I have tried thus far and results:

    1. I ran the inbuilt DELL diagnostics, and all hardware passed the "thorough" tests.
    2. I followed instructions given in this YouTube video: , and used msconfig to locate and uncheck the boxes for (1) WindowsErrorReporting and (2) ProblemsReportandSolutions. I also used this video's instructions to uninstall iCloud. The result of doing that is, possibly, a slow down in the blinking rate of icons within the taskbar and on the desktop, but the flashing continues. This was done during Windows normal mode (while icons were blinking); I have yet to attempt these same steps while in Windows Safe Mode.
    3. I then followed instructions given in this YouTube video: , and used regedit to locate (1) ForegroundFlashCount and (2) ForegroundLockTimeout and reset each of those to 0 (zero). The result of doing that is no improvement/change in the flashing icons.
    4. I also used Windows Restore to go back to 4 OCT 2018. That has not helped, either.

    I think there was an automatic windows update done on my PC, overnight sometime after 5th OCT. I would like to know how to go about identifying and undoing the last Windows update? and how to disallow automatic updates from Microsoft?

    I do not know what to do next. Any help would be appreciated.

    TNX.
