A. B. C. D.

A.

The FIRST thing the technician should do in this scenario is to check the power cable connection (option A). It is possible that the power cable got disconnected or loosened during the move, preventing the PC from receiving power.

Option B, checking the voltage of the PSU with a tester, can be a useful step in troubleshooting a non-functioning PC, but it is not the first step to take in this situation. Before testing the PSU, the technician needs to ensure that power is reaching the PC.

Option C, testing for distended capacitors, is also a valid troubleshooting step, but it is not the first step to take in this scenario. Distended capacitors can cause a variety of issues, but a PC not receiving power is unlikely to be caused by this problem.

Option D, checking the voltage switch, is also unlikely to be the cause of the issue. Voltage switches are typically only found on power supplies that can be used in different regions with different power standards. If the PC was previously functioning and is now not receiving power, the voltage switch is unlikely to be the culprit.

In summary, when a PC is not receiving power after being moved to a new location, the technician should first check the power cable connection (option A) to ensure that power is reaching the PC.
