[Fix] Computer Beeps Then Shuts Off (100% Working)

Share on:

It’s often annoying when you start your PC, it starts and makes a beeping sound, then it goes dark or simply your pc turns off. The beeping sound is significant to understanding the problem here. When a computer is turned on, one of the very first things it does is run a ‘Power On Self-Test’, in which the pc system runs a test on hardware diagnostic to ensure everything is operating properly. The beeping sound denotes an individual error code that will assist you in diagnosing the problem. The meanings of the beep codes differ between BIOS manufacturers. For example, a single beep from your laptop or PC indicates that the computer is booting up. A computer that generates beeping sounds while turning on indicates it has a serious malfunction that prevents the device from booting up. Let’s find out what those beeps mean and how to get rid of them.

Recognize Computer Beep Noise

Hearing a single short beep is fine and it signals that your system is starting up, hearing a sequence of beeps typically means an internal fault. Each set of beeps represents a specific problem and refers to a different location of the problem on your computer.

  • very short beep indicates a problem with the motherboard. It could also indicate problems with your internal storage. (BIOS AWARD).
  • long beep followed by three consecutive short beeps indicates a problem with the graphics card configurations. 
  • short beep followed by three consecutive longer beeps indicates that you have an issue with the system memory.
  • If you hear a beep, pause, beep, pause, and then two consecutive beeps, the problem is with your CPU (central processing unit) 
  • Three beeps, pause, three beeps, pause, followed by four beeps, suggests a video memory problem. 
  • A longer beep followed by nine small beeps indicates an issue with the ROM (BIOS AWARD) 
  • Three beeps, pause, four beeps, pause, followed by a beep indicates a graphics card issue
  • Four beeps, pause, three beeps, pause, and then one beep indicate a problematic system memory.
  • Five brief beeps are another sign that your CPU is malfunctioning.
  • Long, constant beeps are to alert about problems with system memory.

How to Fix ‘Computer Beeps Then Shuts Off’ Problem?

A major hardware fault may occur if the computer makes a beep sound and the system fails to boot properly. Check that no obstacles (papers or specks of dust) are blocking vents, as heat is frequently the major issue. Remove any dust from the cooling vents. Check that the cooling fans are running quietly. Here are a few basic steps for resolving beeping issues:

  • Switch off the PC.
  • Take out the power cable.
  • Disconnect any additional peripherals printer, scanner, etc.) and remove any media from the drives (CD, DVD, USB, Memory sticks, etc.).
  • Plug in the power cable and restart the PC.

  • Switch off the PC.
  • Take out the power cable.
  • Remove mouse and keyboard connections from the PC.
  • Plug in the power cable and restart the PC.


The most common causes of beeping noises of your PC while booting up are hardware failure due to heating issues, keyboard malfunctioning, RAM or ROM malfunctioning, or the motherboard hardware problems. If none of the above steps are fruitful you should immediately take your PC to a service center and talk to an expert.
