Step 1:Let's solve this systematically:
Step 2:: Analyze the Symptoms
The customer reports: - PC doesn't always turn on - Randomly shuts off for hours - HDD and RAM tests are positive (ruling out those components)
Step 3:: Diagnostic Reasoning
When a computer has intermittent power issues and random shutdowns, the most likely culprit is the power supply unit (PSU).
Step 4:: Component Elimination
- NIC (Network Interface Card): Affects network connectivity, not power - EXT-USB: External USB ports don't cause system-wide shutdowns - HDD: Already tested, ruled out - PS/ 2: Peripheral connection port, not related to power issues - SSD: Storage device, not causing power problems
Step 5:: PSU Characteristics
A failing Power Supply Unit (PSU) can cause: - Inconsistent system startup - Random shutdowns - Unpredictable power delivery
Final Answer
PSU (Power Supply Unit) The PSU is the most likely component responsible for the described symptoms, as it directly manages power distribution to all system components and can cause erratic behavior when failing.
