Explanation

The CompTIA A+ troubleshooting methodology requires that if a tested theory (replacing the PSU) does not resolve the problem, the technician must re-establish a new theory of probable cause. The system still won't power on, so the root cause is something other than the power supply - possibly the motherboard, power button, or a short. Questioning users or documenting the replacement are steps for different phases, and escalating to upper management is premature when there are still logical troubleshooting steps to take.
