Blue Screen of Death (also known as BSOD or a STOP error) is a blue screen error that is displayed in full-screen and usually indicates that the system has crashed. The blue screen often displays a text description about the problem that has occurred, however, this is simply an error code and will of be of little use unless you are an advanced user. Windows only suggests that you search for a more detailed explanation online. At this point, the only option is to restart the computer.

There are various reasons for the occurrence of the Blue Screen of Death. BSOD's are generally caused by problems with computer hardware or driver software. Each problem has a specific code (displayed at the bottom of the blue screen).

How To Fix BAD_SYSTEM_CONFIG_INFO Error By Fixing Windows Registry

Windows Registry, usually referred to as just the registry, is a collection of databases of configuration settings in Microsoft Windows operating systems. It is used to store much of the information and settings for software programs, hardware devices, user preferences, operating system configurations, and much more. Many of the options exposed in the registry are not accessible elsewhere in Windows. Registry issues can cause the "BAD_SYSTEM_CONFIG_INFO" error. In order to fix this error, you first need to resolve the Windows Registry problem. Launch Automatic Repair by following the previously-mentioned steps and open Command Prompt.

ren C:\Windows\System32\config\SOFTWARE SOFTWARE.old
ren C:\Windows\System32\config\SYSTEM SYSTEM.old

How To Fix BAD_SYSTEM_CONFIG_INFO Error By Using System Restore

The System Restore tool creates restore points. A restore point is a collection of important system files stored by System Restore on a given date and time. System Restore reverts everything to a saved restore point, but first, you must have one recorded. If a restore point does not exist on your computer, System Restore has nothing to revert to. To use this tool, you must have created restore points. With a created restore point, this feature will bring your system back to the previous working state, without affecting your files and data. To launch System Restore, access Automatic Repair, click "Troubleshoot", click "Advanced options", and then select "System Restore". Select your account username and follow the instructions. If there are restore points created, you will see a list of them. Mark the "Show more restore points" checkbox, which should display more restore points. Select the most appropriate restore point (depending on the time created, etc.) and click "Next". Do not select a Restore Point at a time when the "BAD_SYSTEM_CONFIG_INFO" error was already present - you certainly do not want to revert to that state.
