Troubleshooting steps

  1. Check Monitor Cables
    In case you are using a desktop computer you need to check on the cables between your monitor and your CPU. Check that every cable is well and firmly connected in its opposite socket. This may be the problem in most black screen cases.
  2. Wakeup your monitor
    In Windows 10 sometimes the Windows is just not discovering the monitor. So, you can try waking up the monitor by pressing the following buttons from your keyboard “Windows Key + Ctrl + Shift + B”.
  3. Monitor connections
    If the black screen issue appears to you before signing into Windows, then it may be a connection problem between your monitor and the computer. So, to figure out where the problem resides try the following steps:
    a. First, you need to check if the monitor is connected probably to the power outlet and to your computer.
    b. If recently you have installed a graphics card then check if it is probably installed.
    c. Try to connect another monitor to your computer the problem may be in your default monitor.
  4. Graphics Card Driver
    If recently you have updated your computer or laptop graphics card before the black screen issue appeared then you need to roll back this update. You can follow next steps to rollback but you need to login to Windows in safe mode:
    a. Turn off your computer or laptop by pressing and holding down the power button for 10 seconds.
    b. Press the power button on your computer or laptop and immediately start pressing the F8 button repeatedly. This will open the Advanced boot options.
    c. Press Safe Mode option.

    Properties→ Select Driver tab → Select Roll Back Driver.
    Try restarting your computer and check if the problem still exists.
  5. The computer is not Booting
    If your computer is not booting you will get a black screen. So, you have to make sure that it turned on when you press the power button. After that, you have to listen carefully to your computer or laptop sounds and watch the LEDs. You should hear computer fans turning on making noise, in case you are using a magnetic hard disk you may hear a noise which indicates that it is working to load the operating system.
    If your computer or laptop is not giving any noise this means something is going wrong with your CPU, not the monitor. In this case, it’s recommended to send your CPU to some professional technician.
  6. Software installation
    A black screen may appear during the installation process of software and depending on your machine resources the Windows may be working in the background to complete installation that may take a couple of hours and sometimes it can take up to 3 hours.
    In this situation, there is nothing to do except waiting but in case you have been waiting for more than 3 hours then definitely something went wrong with the installation process and it is stuck. So, to fix this situation try the next few steps:
    a. Power off your computer or laptop by pressing and holding down the Power button for 10 seconds.
    b. Remove or unplug the power cable.

    e. After 60 seconds you can reinsert the battery in your laptop and reconnect your power cable in your computer or laptop but do not reconnect any of your peripherals now.

    The second probability is that the installation process fails and everything is rolled back. You can start the installation again and see what will happen in most cases the installation completes successfully then you can reconnect all your peripherals one by one.
  7. Remove Peripherals
    Sometimes an external device may cause the black screen issue. So, try to disconnect all non-essential peripherals connected to your computer or laptop.
