Question

After upgrading a customer's motherboard and CPU, the PC will not boot. The technician can hear a single long beep lasting 4-5 seconds. This beep repeats until the unit is powered off. Which of the following is the MOST likely cause of this alarm?

Options

  • AThe technician has shorted out the motherboard.
  • BThe technician has not properly seated the RAM.
  • CThe technician has not connected the keyboard.
  • DThe power supply is insufficient for the upgrade.

Explanation

POST (Power On Self Test) beep codes are generated by the BIOS to signal hardware errors before the system can display anything on screen. A single continuous or long repeating beep is a widely recognized BIOS beep code indicating a memory (RAM) failure or that RAM is not properly seated. During a motherboard swap, RAM modules must be reseated into the new board. A shorted motherboard would typically prevent any power at all. An unconnected keyboard may generate a beep on some legacy systems, but not a long repeating beep. An insufficient power supply would more likely cause a shutdown or failure to post power at all, not a specific beep pattern.
