Though one leading cause of too much current being put through the board, besides too much voltage at the inputs (in case of a power supply fault), is the motherboard drawing too much current. Which can well be caused by failing components shorting out, for example. Or a voltage regulator on the board producing too much voltage.
Saying a fried motherboard is generally not caused by the board itself is not true.
What I meant was it's most likely broken third-party power-supplies, using sockets without proper grounding, or problems with the electrical wiring.
