Safe Mode starts your computer with a limited set of files and drivers, but Windows continues to run. The words “Safe mode” will appear in the corners of your screen if you’re in it.

If the cng.sys problem persists, see if it happens when the PC is in Safe mode.

If a significant problem leads Windows to shut down or reboot unexpectedly, blue screen errors linked with the cng.sys file can occur. These errors are caused by hardware and software issues.

Shut down the computer, remove the hardware, and reboot if you introduce new hardware before getting the cng.sys issue (you can also boot in Safe Mode).
