A technician is troubleshooting a desktop workstation that fails to complete POST and emits a continuous beep code immediately after a memory upgrade. Place the following troubleshooting steps in the correct sequence to isolate the issue according to standard CompTIA hardware diagnostic procedures.
- 1Power off the workstation, disconnect the AC power cord, and hold the chassis power button for 5 seconds to drain residual electrical charge.
- 2Remove the newly added memory module, leaving only the original, known-working RAM installed.
- 3Reconnect power and boot the workstation to verify if the baseline system completes POST successfully.
- 4Install the new memory module individually into a known-good slot to test the module for defects.
Cevap
The correct sequence begins with disconnecting AC power and draining residual electricity, removing the newly installed RAM module to re-establish a baseline, powering on the system to verify baseline operation, and finally testing the new RAM module independently in a known-good slot.
CompTIA hardware troubleshooting principles mandate establishing safety first by removing power and draining residual charge, returning to a known-good baseline by removing newly added RAM, verifying baseline system operation, and then testing the new module independently to isolate component versus slot failure.
