The wikipedia explanation page.

https://en.wikipedia.org/wiki/Machine-check_exception

Some quotes from that page.

"A Machine Check Exception (MCE) is a type of computer hardware error
that occurs when a computer's central processing unit detects a
hardware problem."

"Normal causes for MCE errors include overheating and/or incorrect
hardware installation. Specific manually-induced causes include:

    overclocking (which normally increases heat-output)
    poorly-fitted heatsink/computer fans (the same problem can happen
    with excessive dust in the CPU fan) 
    an overloaded internal or external power-supply (fixable by
    upgrading) "
