Which action provides quick confirmation of a hardware fault without altering software?

• A. Replace the entire system
• B. Run a software diagnostic
• C. Update the device drivers
• D. Reseat cables and components and then test for symptoms

Answer: (D)

Quickly confirming a hardware fault without changing software is best done by reseating cables and components and then testing for symptoms. This approach directly targets the physical connections that can cause intermittent or no-contact issues, without altering any software state. Power down, unplug, reseat items like RAM sticks, expansion cards, and storage or interface cables, then power up and observe whether the symptoms persist or resolve. If reseating fixes the issue, it points to a loose or poor connection as the fault; if not, you’ve eliminated many connector-related causes and can proceed to deeper hardware checks. Why this works better than the other options: replacing the entire system is heavy, time-consuming, and unnecessary for a quick check. running a software diagnostic looks for software and OS level problems and may miss a hardware fault or even mislead you into thinking the software is at fault. updating device drivers changes software behavior and can obscure the true hardware condition. reseating is fast, inexpensive, non-destructive, and provides immediate evidence about hardware integrity.
