    When it does blink, does it go black then back to normal screen ? Now it could be failing hardware, bad connection from hinge to monitor and even possible interference. Also could be the Video adapter drivers are corrupted.

    This is the laptop ?
    https://www.asus.com/Notebooks_Ultrabooks/X450JN/

    I believe from specs shown here it has a NVIDIA Geforce 840M, if you can double check that, go to the Control panel then the Device manager, go to Display adapter left click it, it should tell you there the model.

    If it is correct NVIDIA, first thing i would do is uninstall older drivers, either go back to Control Panel in Programs and Features do it there, but first download the latest drivers here NVIDIA DRIVERS GeForce Game Ready Driver WHQL

    After uninstall reboot and install one you downloaded, see first if this helps the blinking.

    Yes, you have right link for driver, same one i gave you. Uninstall it from Programs and features and even open up Display adapters in Device Manager and uninstall it there to, reboot and install new one. Seem have the older drivers i see from picture. This is my first step to see if the video card drivers are causing the issue, maybe files from drivers are corrupted or there is a conflict.

    Alright, said had it in for repair and found no hardware issues. Still could try to test the display as this laptop has a VGA port, do you have another monitor can hook to it to try if it happens ?

    When this started happening did you install anything just before software or hardware ? When was last time ran Malwarebytes a full system scan, could be a virus. Other suggestion can be corrupted files, another driver on system conflicting. ASUS site i listed make sure have all newest system and hardware drivers updated and also windows updates.

    Try this at the Start button select (admin) command prompt copy and paste this and press enter

    sfc /scannow

    Same command prompt copy and paste this and press enter

    Dism /Online /Cleanup-Image /RestoreHealth

    Reboot the laptop.

    If SFC command tells you found corrupt files and can or can not fix them still run the other command, let me know. As this will try to fix corrupt windows system files if any.

    Try these steps first, my other suggestion would be to try safe mode see if it happens there then a clean boot, this will try to rule out possibility of a conflicting software or drivers why i say also make sure system has most updated drivers.

    To get to Windows Startup Settings in PC settings


    • Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
      (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)
    • Under PC settings, tap or click Update and recovery, and then tap or click Recovery.
    • Under Advanced startup, tap or click Restart now.
    • Once your PC restarts, on the Choose an option screen, tap or click Troubleshoot.

      If you don't see the Startup Settings option, tap or click Advanced options.
    • Tap or click Startup Settings.
    • Tap or click Restart.
    • On the Startup Settings screen, choose the startup setting you want.
      This case choose Safe Mode #4
    • Sign in to your PC with a user account that has administrator rights.

      Let it run for awhile and see if it happens as not much can do in safe mode as it limits services and other software and drivers from running. We can later also try a clean boot, again this is to determine if any drivers or software is causing this issue, be some last resorts other then a possible reset or refresh. Still may think this might be a bad connection, hardware related too.

    no, stay on 20% for awhile just let it complete. Chances corrupt files found by SFC due to a one Windows update, good chance have it on system.
    DISM might receive a similar error. Check here first tell me if you see update KB3022345.
