A desktop workstation utilized for high-resolution video rendering abruptly powers off without warning after approximately 10 minutes of heavy processing. The technician suspects either CPU thermal runaway or a power delivery protection trip. Place the following troubleshooting and remediation steps in the correct chronological order according to standard hardware troubleshooting methodology, starting from initial diagnostic entry to final system validation.
- 1Access the BIOS/UEFI System Health Monitor screen to examine historical CPU core thermal logs and +12V/+5V power rail status.
- 2Establish a testable theory of probable cause attributing the shutoffs to CPU thermal throttling based on logged peak temperatures exceeding operational limits.
- 3Remove the CPU heatsink assembly, clean off degraded thermal paste, reapply fresh thermal interface material, and securely re-seat the cooler.
- 4Run an isolated CPU stress test utility while actively observing thermal sensor telemetry to verify heat dissipation under load.
- 5Execute a full-system synthetic workload involving simultaneous CPU and GPU stress testing to confirm total power supply and thermal enclosure stability.
Cevap
The correct order of troubleshooting steps begins with inspecting BIOS/UEFI health monitor logs, followed by establishing a theory of thermal throttling, performing thermal interface material replacement and cooler re-seating, conducting a targeted CPU stress test, and concluding with a full-system workload verification test.
Structured hardware troubleshooting follows a logical progression: gathering information from system hardware monitors, establishing a theory of probable cause, implementing the physical solution (clearing degraded thermal paste and reseating the cooler), verifying component-level resolution via targeted testing, and finally validating comprehensive system stability under maximum full-system load.
