One of the servers in the datacenter shuts down multiple times a day. The technician has to physically go to the server and boot it up by pressing the power button. Which of the following are MOST…

Overheating activates the server's built-in thermal protection mechanism, which performs an automatic shutdown to prevent CPU or component damage. This pattern - repeated shutdowns requiring a manual power-button restart after the system cools - is a classic symptom of inadequate cooling, blocked airflow, or failed fans.

Processor failure typically manifests as system crashes, kernel panics, or frozen states rather than clean power-off events that require pressing a physical power button to restart.

I/O failures affect disk or peripheral communication and typically produce read/write errors, application hangs, or storage-related faults rather than causing the server to fully power off.

A degrading or undersized power supply can deliver inconsistent voltage or fail under load, causing the server to lose power abruptly and require a manual restart each time. PSU failures are a primary hardware cause of repeated unexpected shutdowns in servers.

An incorrect boot sequence affects what device the server attempts to boot from during startup and would cause boot failures, not repeated shutdowns of an already-running server.
