    Start with isolating whether this is a display driver problem or an app conflict.

    1. Reset the graphics driver when the screen flickers:
      • Press Windows + Ctrl + Shift + B.
      • If that does not help, restart the laptop.
    2. Check whether Task Manager flickers when the issue happens:
      • Press Ctrl + Alt + Delete and open Task Manager.
      • If needed, press Ctrl + Shift + Esc.
      • If Task Manager flickers too, the display driver is the likely cause.
      • If Task Manager does not flicker while the rest of the screen does, an incompatible app is the likely cause.
    3. If the display driver is the likely cause, use Device Manager:
      • In the taskbar search box, type device manager and open it.
      • Expand Display adapters.
      • Right-click the display adapter.
      If Windows Update recently changed the driver, try Properties > Driver > Roll Back Driver > Yes, then restart. Otherwise try Update driver. If that still does not fix it, try Properties > Driver > Uninstall Device, select the option to remove/delete the driver software if shown, then restart so Windows attempts to reinstall the driver. Note: rolling back or uninstalling a driver requires administrator privileges. Uninstalling the driver is a higher-risk step because display behavior may temporarily worsen until Windows reinstalls the driver.
    4. If an incompatible app is the likely cause:
      • For Microsoft Store apps, install app updates.
      • For non-Store apps, get updates from the app manufacturer.
      • If the problem continues, uninstall recently added or suspect apps one at a time:
        • Windows 10: Start > Settings > Apps > Apps & features
        • Select the app > Uninstall > Uninstall
        • Restart after each removal and test before removing the next app.
    5. If the screen is too unstable to follow the steps, start the PC in safe mode and then perform the driver uninstall or app removal steps.

    Because the issue persisted across Windows 11 and Windows 10 and also after reinstalling drivers, the most useful next step is the Task Manager flicker test. That determines whether to focus on the display driver path or the incompatible app path instead of repeating full Windows reinstalls.

    • Pressing Windows + Ctrl + Shift + B. does nothing
    • if i attach an external monitor, the external display has no issues even if the laptop screen is flickering or going black

    Please check to see if your laptop is producing any small Watchdog dump files, I will check those to see if they provide any insight into a potential cause of the system crashes.

    Open Windows File Explorer.

    Navigate to C:\Windows\LiveKernelReports

    If there are any Watchdog dump files in the sub-folders of that folder, copy the files onto your Desktop, then zip those up.

    Upload the zip file to the Cloud (OneDrive... etc.), then choose to share those and get a share link.

    Then post the link here to the zip file, so I can take a look for you.
