A blue screen with a stop code that provides information about the issue often indicates a BSOD.

Overheated CPUs can sustain physical damage, which could lead to stability problems and malfunctions. These CPU errors may result in a Blue Screen of Death.

Additionally, a hardware issue, such as a defective internal component or a manufacturing system error, is another frequent reason for BSODs brought on by a malfunctioning CPU.

In some situations, the CPU could be incompatible with the motherboard or the BIOS, resulting in errors and instabilities.
