Flickering Display

Systems experiencing a flickering/flashing screen after upgrading to Window 10 are being affected by apps causing Explorer to crash, or display driver issues.

Troubleshooting Steps

The first step is to determine if the issue affects Windows Task Manager. If Task Manager is flickering the likely cause is a Software compatibility issue that causes Explorer.exe to crash repeatedly. If Task Manager is not affected, the likely cause is Display Drivers. To test Windows Task Manager, press: CTRL+SHIFT+ESC.

To Troubleshoot Software Compatibility, Follow These Steps:

NOTE: If Task Manager is flickering, or it didn’t open, try the same steps in Safe Mode
  1. Use the File, Run option in Task Manager to open additional tools as-needed. Be sure to check the box to run tools as Administrator. These could include:
    • appwiz.cpl: Opens Programs and Features
    • compmgmt.msc: Opens Computer Management cmd.exe
  2. You can search for crash events in the Event Logs and find if any third party DLLs are the faulting module in the Explorer.exe crashes, Or uninstall software that is likely to include shell extensions.
  3. If removing software does not resolve the issue, use these commands to repair Windows:
    dism /online /cleanup-image /restorehealth
    sfc /scannow
    Note: A reinstall of Windows 10 from the Dell recovery tool may also work even if sfc /scannow does not find any issues.

The following applications have been shown to contribute to flickering issues. Uninstall these to test if they are the cause:

  • Norton Antivirus (Symantec)
  • Other Anti Virus solutions
  • iCloud
  • LiveUpdate6
  • IDT Audio (faulting module IDTNC64.cpl)

To Troubleshoot Display Drivers, Follow These Steps:

  1. Boot to Safe Mode with Networking.
  2. Use the same steps here as for Black Screen issues – if the system has a dual graphics chipset (Both Integrated and Discrete Graphics), disable built-in graphics, if still flickers, try with only the other chipset enabled.
  3. If this does not work, or there is only a single chipset, uninstall the device and remove the driver software.
  4. Then boot into Windows and update the drivers to the latest from
