Difficulty: HardTroubleshooting Methodology

A desktop technician is assigned to troubleshoot a high-end graphics workstation that unexpectantly shuts down during intensive 3D rendering tasks. Place the technician's diagnostic and remedial actions in the correct sequential order according to the CompTIA 6-step troubleshooting methodology, from first action to last action.

  1. 1Interview the user about crash symptoms and inspect OS event logs for thermal warning events.
  2. 2Formulate a hypothesis that clogged heatsink fins and degraded thermal paste are causing CPU thermal throttling and shutdown.
  3. 3Run a hardware monitoring utility during a stress test to observe if CPU core temperatures exceed critical thresholds.
  4. 4Shut down the workstation, remove dust buildup from cooling fins, reapply thermal compound, and remount the heatsink.
  5. 5Execute a full rendering workload test to confirm temperature stability, then log the root cause and remedy in the ticketing system.

Answer

The correct order follows the standard CompTIA troubleshooting process: first interview the user and review event logs (Identify the problem), second formulate a hypothesis regarding thermal failure (Establish a theory), third run a stress test while monitoring hardware sensors (Test the theory), fourth clean the cooling components and reapply thermal paste (Implement the solution), and fifth perform a stress test to confirm fix and document findings (Verify system functionality and Document).
The correct sequence strictly adheres to the standard 6-step CompTIA troubleshooting methodology: 1. Identify the problem (gather user reports and logs), 2. Establish a theory of probable cause (hypothesize thermal throttling), 3. Test the theory (stress-test with temperature monitoring), 4. Implement the solution (clean heatsink and reapply thermal paste), and 5. Verify full system functionality and document findings (stress-test validation and ticket documentation).

Step-by-Step Solution

1
Gather diagnostic details from user reports and event logs.
Identified symptoms and error logs indicating thermal emergency shutdowns.
CompTIA Step 1 requires identifying the problem before forming theories or taking action.
2
Develop a theory regarding heat dissipation failure.
Targeted clogged heatsink fins and old thermal compound as probable cause.
CompTIA Step 2 requires establishing a theory of probable cause based on collected data.
3
Test the thermal theory using diagnostic software under load.
Confirmed CPU thermal limits were breached under stress.
CompTIA Step 3 requires testing the theory to confirm the cause before modifying physical components.
4
Clean heatsink fins, reapply thermal paste, and reassemble cooling.
Physical solution implemented successfully.
CompTIA Step 4 requires establishing a plan of action and implementing the solution.
5
Run extended workload test to confirm stability and record resolution notes.
System validated under load and ticketing record completed.
CompTIA Steps 5 & 6 require verifying full system functionality and documenting the outcome.
