Question:

What could be the cause of a sudden shutdown and boot failure of my PC?

I was playing a game on my PC when it unexpectedly turned off and did not restart. I have checked the RAM, the CMOS battery, and the power supply, but none of them seem to be the issue. I have also tried to boot from a Windows installation USB, but it failed with the following error codes: 0xc0000428, 0xc0000229, and 0xc000003f. I suspect that there might be some hardware damage or corruption in the system files, but I am not sure how to diagnose or fix it. Do you have any suggestions or solutions for this problem? I appreciate your help.

Answer:

If your PC suddenly shuts down and fails to boot, you may encounter a blue screen of death (BSoD) with the error code 0xc0000428. This error indicates that Windows cannot verify the digital signature of a file, which could be a driver, a system file, or a boot file. This could happen due to various reasons, such as:

• An outdated or corrupted BOOTMGR file, which is responsible for loading the operating system.
• A recent hardware or software change that installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
• A faulty or incompatible hardware device or driver that interferes with the boot process.

To fix this error, you need to start your PC from a Windows installation USB or DVD media, and then try the following methods:

• Method 1: Disable driver signature enforcement. This option allows you to temporarily bypass the digital signature verification and start Windows without this file. To do this, you need to access the Advanced Boot Options menu by pressing F8 when you see the Windows logo. Then, select Disable driver signature enforcement and press Enter. If your PC boots successfully, you can try to identify and uninstall the problematic driver or file that caused the error.
• Method 2: Repair the BOOTMGR file. This option allows you to restore the BOOTMGR file to its original state and fix any corruption or damage. To do this, you need to access the Windows Recovery Environment by clicking Repair your computer on the first screen of the Windows installation media. Then, select Troubleshoot, Advanced options, and Command Prompt. In the command prompt, type the following commands and press Enter after each one:

“` bootrec /fixmbr bootrec /fixboot bootrec /rebuildbcd “` If you see a message that says “Successfully scanned Windows installations. Total identified Windows installations: 1”, press Y to add the Windows installation to the boot list. Then, restart your PC and see if the error is resolved.

• Method 3: Restore the system files. This option allows you to replace the corrupted or missing system files with the original ones from the Windows installation media. To do this, you need to access the Windows Recovery Environment as in Method 2. Then, select Troubleshoot, Advanced options, and Command Prompt. In the command prompt, type the following command and press Enter:

“` sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows “` Note: You may need to replace C: with the drive letter of your Windows partition. This command will scan and repair the system files. It may take some time to complete, so please be patient. After the scan is finished, restart your PC and see if the error is fixed.

If

none of these methods work, you may need to reinstall Windows or contact a professional technician for further assistance. We hope this article has helped you to understand and solve the error code 0xc0000428. For more information, you can refer to these sources . Thank you for reading..
