Difficulty: EasyMotherboard, RAM, CPU, and Power Issues

A technician is troubleshooting a newly assembled desktop computer. When pressing the power button, the fans spin and power LEDs illuminate, but the monitor receives no signal and the system emits a continuous sequence of POST beep codes. Which of the following actions should the technician take FIRST to address these startup symptoms? (Select TWO.)

  1. Reseat the RAM modules in the motherboard memory slots.Answer
  2. B
    Reinstall the operating system using bootable installation media.
  3. Verify that the display cable is connected to the dedicated GPU rather than the integrated video port.Answer
  4. D
    Replace the installed memory modules with SO-DIMM form factor memory.

Answer

The technician should reseat the RAM modules in the motherboard slots and verify that the display cable is connected directly to the dedicated graphics card.
POST beep codes directly indicate a hardware detection issue during initial system power-on, with unseated or faulty RAM being a primary cause. Additionally, absent display signals on newly built systems often occur when the monitor is mistakenly plugged into the motherboard integrated graphics port instead of the installed discrete graphics card.

Step-by-Step Solution

1
Analyze system startup behavior and POST audible diagnostic indicators.
System receives power but encounters a hardware initialization failure identified by POST beep codes and lack of display output.
Beep codes signal physical hardware initialization errors before the motherboard BIOS/UEFI can pass control to the operating system bootloader.
2
Isolate potential hardware connections for memory and video output.
Reseating RAM verifies physical contact in the motherboard slots, and checking video cable placement ensures output is drawn from the active discrete GPU.
Improperly seated RAM prevents successful POST completion, while plugging the monitor into an unpowered integrated display port prevents visual display output.

Key Concept

Identifying early hardware POST failures caused by RAM seating issues and improper display adapter cable connections.
