In a working system, it's very uncommon for a high-quality motherboard to fail other than from lightning damage (see Computer Power Supplies and Protection) or other severe abuse. In particular, it's nearly unheard of for a motherboard to fail while it is running, as opposed to when you start the system. A dead system is more often caused by a dead power supply than a dead motherboard, so the first step to troubleshoot an apparently dead motherboard is to swap in a known-good power supply.
