Frequently Asked Questions

Does MACHINE_CHECK_EXCEPTION indicate a hardware fault?
Yes, more directly than many other stop codes — this is triggered by the CPU itself detecting a hardware-level error, making it worth checking for overheating, an unstable overclock, or failing hardware specifically.
Is this more serious than typical blue screens?
It tends to point more directly at actual hardware than many software-related stop codes, so it's worth taking seriously and checking temperatures and any overclocks first.
