Field Scenario

A customer’s desktop randomly shuts down under heavy use, and the customer assumes the motherboard must be failing.

What You Actually Do

• Consider power supply capacity and condition as a genuine possibility before assuming a motherboard failure
• Explain why random shutdowns under load are a classic symptom that can point to several different components
• Systematically test or rule out power supply, overheating, and other common causes
• Avoid jumping to the most expensive-sounding diagnosis without genuine investigation
