Knowledge Management (KM) Definitions. Defining knowledge management (KM) has always been a challenge. For many years I resisted offering a definition because whenever I included a definition in a talk this would become the main focus of attention.
Motherboards can go bad for many reasons, although there are a few common culprits. Among the most common causes of motherboard failure are excess electrical shocks, physical damage, or excess heat. Some of these dangers are inescapable, and may vary in likelihood depending on your computer model.
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.
