This screen appears on various Windows versions whenever a critical error occurs in vital system processes. It can be caused by either corrupted software or defective hardware. A faulty power supply, incompatible drivers, defective RAM and many other factors can trigger this error screen.
Scare Factor: It depends on the severity of the error.
Medium to nightmare. The error appears jarringly and will startle those who are not expecting it. Knowing that something is wrong with the computer can increase the scare factor. Or others might just find it annoying.Nightmare if sound enters an audio loop. The stuttering is very loud and ear-grating. It could also damage to audio equipment if loud enough. Medium for the Windows 8 and Windows 10 variants. It's still troubling, but the screen looks more friendly.
