Fix 5. Perform a Startup Repair

Since BIOS deals with computer startups, any issues within the startup files can stop BIOS configuration, forcing the system to display a black screen. To tackle this, do a startup repair, it can identify and repair all defective files causing this error. The procedure to perform a startup repair is quite simple.

Step 1. Press and hold the power button for 5 seconds to turn off the system.

Step 6. The system will check and repair all files.

Step 7. Now restart the system and check the status of the error.

Fix 6. Turn off Fast Startup

The fast startup helps to start the system quickly. When the fast startup is on, the system makes a hibernation file to store the driver, programs, and current state. This file is responsible for fast startup. However, any problem in this file can result in a black screen. In such a scenario, you need to turn off the fast startup option. Follow these steps for this.

Step 1. Press Windows + R to run the dialog box.

bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd

Step 5. Type "Exit" and Press Enter.

Step 6. Restart your system, the error will be fixed.

Fix 8. Check for GPU

The graphical processing unit, GPU, controls all the system graphics. The GPU can lose functionality due to dirt, damage, and overheating. A faulty GPU will produce an idle black screen. Therefore, it is necessary to complete GPU Checkup.

The main component of GPU is your graphics card.  Remove the card from the PCIe x16 slot and check its condition. If it is worn out or defective, replace it. If not, insert it again and start the system.

Fix 9. Rollback/Reinstall Graphics Driver

The graphics driver controls how the graphics interact with the rest of the computer. It is a piece of software with limited instructions. Sometimes a graphics driver update can disturb the BIOS settings, halting the startup procedure. As a result, you see the same black screen problem.

The remedy for that is to roll back the driver update. You boot your system to Safe Mode and use the previous driver configurations, which allows smooth startup. This negates all updates causing startup problems. The process involves these steps.

Step 1. Turn off your system.

Step 2. Connect the recovery drive and turn it on.

Step 3. Select "Repair your computer" and then choose "Troubleshoot".

Step 4. Now visit "Advanced Options", click "Startup Settings", and choose "Restart".

Step 5. When the system restarts, press F5 to proceed to "Safe Mode with Networking".

Step 6. Type Win+X on device options and expand the "Display Adapters" option.

Step 7. Right-click on your graphic driver and see its properties

Step 8. Now move to the driver tab and select "Roll Back Driver".

Step 9.  The system will cancel all the updates. Now restart the system. The error will not be there.
