pc randomly shutoff and is stuck on a black screen with motherboard logo saying "preparing system repair"

Users may, in theory, get a blank screen following systematic repair for a variety of reasons. The system doesn't react or boot properly in this case.

The following factors may prompt Windows to set up an systematic black screen fix.

• Most often, it occurs when the bootloader or crucial booting files are missing.
• This might potentially be caused by a Master Boot Record (MBR) that is corrupt.
• This issue can also be brought on by changes to BIOS settings or a lack of Boot Configuration Data (BCD).
• The hard disc may also not exist, be corrupted, be missing, or have a loose connection.

Windows Black Screen Troubleshooting: Boot in Safe Mode

You may cure the Windows 10 automatic repair black screen by safely restarting your computer if the problem was fairly minor. The ideal scenario is that it will just load the necessary parts and offer a better Windows environment for troubleshooting.

Step 1. Go to the Windows Recovery Environment(WinRE)by doing the following steps:

Press the power button to turn off your device.

Press the button again to turn it on.

Once Windows starts, press on the power buWinREtton again for 10 seconds to turn it off. Then press it on again.

Upon the reboot, hold on to the power button for 10 seconds to turn it off, then turn it on again.

Because you've repeatedly turned on and off your PC, you will be redirected to WinRE.

Step 2. Once you get the Advanced Startup screen on your Windows 10 computer, go to its Troubleshoot > Advanced Options.

Step 3. From all the provided options here, click on the "Startup Settings" feature.

Step 4. This will list different tasks that you can perform in the startup settings. Just click on the "Restart" button to continue.

Step 5. The screen will list various operations that you can perform now, including restarting your system in the safe mode. Just press the key that denotes the Safe Mode (like "4" in this case).

Step 6. That's it! This will make your system restart in safe mode. Once you get the following screen, you can select your choice and boot your Windows in safe mode.

Both Master Boot Record (MBR) and Booting Configuration Data (BCD) are crucial to a system's booting. While MBR maintains a log of the system's booting sequence, BCD holds all the vital configuration data needed to load the firmware. If either of these components is corrupt or is not working, then it can cause the Windows 10 preparing automatic repair black screen issue.

Reinstall the graphics driver again

In addition to firmware, your system's loaded graphics drivers may also be problematic. For instance, the issue with the automated repair black screen might be brought on by an out-of-date display driver or faulty software.

If you have updated your graphics driver in the wrong way or a change in its settings has caused the issue, then you can consider this option. In this, we will roll back the display driver settings to a previous update to avoid any conflict. All you got to do is open the Device Manager window and double-click the display driver you wish to downgrade. Afterward, go to its "Driver" tab and click on the "Roll Back Driver" button.

Hope the above-mentioned steps help you out.
