What is the Bad System Config Info BSOD Error?

If you have faced a BSOD error for the first time or just want to know about it in detail, then you must want to learn more about the “Bad System Config Info” BSOD error. This type of BSOD error is one of the most common ones out there. It is generally caused when Windows is not able to complete multiple processes at once due to issues with the system configuration data and files. However, this BSOD error might not be directly connected to the system configuration data itself.

Causes of the Bad System Config Info BSOD Error

Even though the name itself suggests that the “Bad System Config Info” BSOD error is caused due to improper system configuration data and files, this error can also be caused due to other reasons. This is due to the reason that if any other error or issue on your computer restricts Windows from accessing the system configuration file or corrupts it, then you may face this BSOD error. Similarly, here are some other common causes of the “Bad System Config Info” BSOD error on Windows:

Incorrect Registry Configuration

As you would expect, the most common and obvious cause of the “Bad System Config Info” BSOD error is that the system registry configuration is corrupted or incorrect. If your computer has any incorrect registry configuration, then Windows may not work properly. This can then result in the “Bad System Config Info” BSOD error again and again.

Corrupted Windows System Files

Apart from having incorrect or corrupted system registry configuration, the Windows operating system of your computer itself may have corrupted system files.

Corrupted or Damaged RAM

Other than facing the “Bad System Config Info” BSOD error due to software or operating system issues, you can also face the same because of hardware failure.

Corrupted BCD or Boot Configuration Data

Whenever you turn on your computer, the BCD or the Boot Configuration Data file is responsible for loading up the operating system from your hard drive or SSD.

Thus, it can also lead to the “Bad System Config Info” BSOD error.
