Blue Screen of Death (BSoD) errors like the BAD_SYSTEM_CONFIG_INFO may arise at Windows startup, and without context. If you have encountered this issue, you are not the only one. Usually, the computer restarts on its own after it flashes the BSoD.

Overview of BAD_SYSTEM_CONFIG_INFO

The Bad System Config Info error is a BSoD that arises from a Boot configuration file issue. There are instances when the older files are in conflict with the stable or newer files. It may also be caused by a bug in the system Registry.

If you get this stop code, you will need to follow a few different methods to resolve this problem. However, most of these solutions can only be done if the PC is able to reboot. If not, you can try restarting in Safe Mode before following the steps.
