Those of you who have had a component die have probably wondered what caused it to go bad. Things like hard disks and fans have moving parts, so mechanical failures make sense. Simple friction and heat cause things like head actuators and disk heads to fail after their lifespan is up. Motherboards have capacitors which fail. Conventional electrolytic capacitors, especially when in CPU voltage regulators, are under a lot of stress and can fail or even explode. But what about the true solid state...
