Computer Does Not Post

When someone says “It’s Not Posting” in the context of computers, they are referring to an issue encountered during the initial boot-up process of a computer. This article will explore what this phrase means, its implications for computer operation, and the typical steps involved in troubleshooting the issue.

What Does “Not Posting” Mean?

The term “POST” stands for Power-On Self-Test. This is a diagnostic testing sequence run by a computer’s firmware (typically the BIOS or UEFI) immediately after it is powered on.

Understanding POST

  • Function: The POST checks the computer’s hardware to ensure everything is functioning correctly before starting the operating system.
  • Indicators: During POST, a series of beeps or LED codes (depending on the motherboard) can indicate the status of the hardware components.

When It’s Not Posting

  • Meaning: If a computer is “not posting,” it means the system is failing to pass these initial diagnostic tests.
  • Symptoms: Common indicators include the computer not displaying anything on the monitor, no beep sounds (if the motherboard has a beep code speaker), or showing error codes through LEDs.

Common Reasons for a Computer Not Posting

  1. Hardware Failures: Issues with crucial components like RAM, CPU, motherboard, or power supply.
  2. Improper Hardware Installation: Components like RAM or GPUs not being seated properly.
  3. BIOS/UEFI Issues: Problems with the firmware settings or corruption.
  4. Peripheral Issues: Faulty or incompatible peripherals connected to the computer.

Troubleshooting a Computer That’s Not Posting

  1. Check Power Connections: Ensure the power supply is connected correctly and functioning.
  2. Inspect for Visible Damage: Look for any signs of physical damage on the motherboard and other components.
  3. Re-seat Components: Remove and reinsert RAM, graphics cards, and other components to ensure they are properly seated.
  4. Listen for Beep Codes: Beep codes can indicate specific hardware issues.
  5. Disconnect Non-Essential Hardware: Remove all peripherals except for the monitor, keyboard, and mouse.
  6. Reset BIOS/UEFI: Clear the CMOS to reset the BIOS/UEFI settings to defaults.
  7. Check with Minimal Setup: Try booting with minimal hardware (one stick of RAM, no GPU if the CPU has integrated graphics).

FAQs About “It’s Not Posting”

  1. Can a computer not posting be fixed at home?
    • Many POST issues can be resolved at home with basic troubleshooting. However, some problems may require professional assistance.
  2. Does ‘not posting’ mean the computer is broken?
    • Not necessarily. It often indicates an issue that needs fixing but doesn’t always mean permanent damage.
  3. How do I know if it’s a motherboard or CPU issue?
    • This can be difficult to diagnose at home. Professional diagnostic tools or testing with known good components are typically required.
  4. Are there any risks in troubleshooting a not posting issue?
    • If you follow proper procedures, the risks are minimal. However, mishandling components can cause damage, so proceed with caution.
  5. Should the computer be unplugged while troubleshooting?
    • Yes, always disconnect the power source before manipulating internal components.


Understanding the phrase “It’s Not Posting” is essential for diagnosing and troubleshooting the early stages of computer boot-up problems. By methodically checking the hardware and following troubleshooting steps, most POST issues can be identified and resolved. However, some complex issues might require professional diagnostics and repair.
