If I had to guess why a motherboard caught on fire, I'd suspect a broken fan or a heatsink that was missing or improperly installed. If the computer had been powered off for a long time and it still caught on fire, that's a hard one to explain! Maybe an electrical surge burned something? Of course, if that had happened, you probably would've noticed damage on other electronics plugged into the same circuit.
Course clear! You got a card.
