Blue screen of deaths are not news for Windows. They have existed for a long time, the visual manifestations of often fatal system failures that turn your precious machine into an expensive piece of brick. If you have ever encountered a blue screen, especially one that appears when you start your system, you may have something to do with the teeth grinding that many users have experienced.
Fortunately, for every Blue Screen of Death somewhere on the Internet there is a solution that can revive your computer and get rid of the error, and the REGISTRY_ERROR BSOD (0x00000051) error is no exception. In this tutorial we have gathered all the working solutions available to any disappointed user.
Reasons for the error
- There is not enough free space on your computer/laptop hard disk. For Windows 10 to work properly, you must have 2-10 GB of free space on your system hard drive.
- An incompatible BIOS version has been installed or the firmware has been damaged.
- Device drivers that are not compatible with the operating system are installed.
- Windows Registry was corrupted, deleted or system keys were accidentally deleted during a purge.
- Antivirus software or viruses can block system files or delete important registry keys.
- An error has occurred while working with the backup program.
- It can also happen as a result of Windows update.
Restore deleted files
Often BSoD errors lead to loss of important files. Files blocked by computer viruses, backup software errors, damaged or overwritten system files, file system errors or damaged hard drive sectors are just some of the reasons that can lead to a loss.
Fixing the corresponding errors will return your devices to normal operation, but damaged or lost files will not always be recovered. It is also not always possible to fix the bug without formatting your hard drive or reinstalling the operating system, which can also lead to lost files.
Use CHKDSK to scan your drive
- If your computer’s hard drive really shows physical damage, run CHKDSK when you scan your hard drive deeply and fix any problems with your hard drive.
- If the hard disk is badly damaged, the hard disk testing software can help.
- Whichever tool you use to test and fix your PC hard drive problems, be prepared for an early backup of your PC hard drive files.
Reset or restore the system registry of your computer hard drive
- In case the new software has actually deleted or changed the auto-boot registry of your hard drive, carefully check, reset and restore the registry.
- Of course, in case of more serious problems, reinstall the corresponding applications, games and tools and remove them completely.
Run the Windows memory diagnostic test
BSOD REGISTRY_ERROR may be caused by the fact that your RAM is not working properly. Consequently, your computer cannot make maximum use of it during operation. If you continue to use incorrect RAM without realizing it, you may encounter problems that could make your computer unusable. It is therefore better to check your RAM regularly to make sure that it is in good condition.
Windows Memory Diagnostics is a tool specifically designed by Microsoft for this purpose. Although the company has stopped supplying the program and other options to recover your system in Windows after Windows 7, you can still download the program from a third-party website. This is great for identifying potential memory problems.
Once Windows Memory Diagnostic is booted, run the installer and save the CD image on your desktop. Write the image to a CD or DVD. The program starts only from the boot disk. This makes it a great tool when your computer is stuck on BSOD and you cannot access your system. All you have to do is load a Windows Memory Diagnostic CD.
Once the program starts, let it do its job. It will run an endless number of tests until you turn it off or shut down your machine. Keep an eye out for errors. If WMD detects even minor errors, it is recommended to delete the memory and buy a new one. Once you have installed a new RAM on your computer – and provided the error is related only to bad RAM – BSOD REGISTRY_ERROR will no longer be displayed.
Restore or reinstall the PC operating system
Now try to check and correct problems with your PC operating system. If it is really out of date, quickly update the Windows operating system. If some files and folders of the operating system have been removed or corrupted, download a new one to properly restore the operating system. Of course, you can also reinstall the PC operating system. If you used the Piratic version of the operating system, install a licensed version instead.
