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

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.

Common Causes of the Beeping and Shutdown Issue

Beeping noise during booting up your pc may be because of various reasons. The most encountered problems possibly for which beep noise may be generated are given below.

1. A Failing Power Supply

The power supply unit (PSU) is responsible for converting mains AC to low-voltage regulated DC power for the internal components of a computer. If it’s malfunctioning, it can’t provide the necessary power, leading to sudden shutdowns. Symptoms of a failing PSU can include random restarts, irregular power patterns, and, in some cases, a distinct burning smell.

2. Inconsistent Power Coming into the Computer

Sometimes, the issue isn’t with the computer but with the power source it’s connected to. Fluctuations in the electrical grid, faulty outlets, or problematic power strips can provide inconsistent power, causing the computer to shut down unexpectedly.

3. Too Many Devices Drawing Power Internally

Every component inside a computer requires power. If there are too many components (like multiple hard drives, several RAM sticks, or numerous connected peripherals), especially in a system with a lower wattage PSU, it can overload the system, leading to shutdowns.

4. RAM Malfunctions

Random Access Memory (RAM) is crucial for a computer’s operation. If RAM sticks are faulty, not seated properly, or incompatible, the computer might beep (a way motherboards communicate issues) and then shut down. Faulty RAM can also lead to blue screens and random restarts.

5. The CPU Getting Too Hot

The Central Processing Unit (CPU) is the brain of the computer. If it overheats, most modern computers will shut down automatically to prevent permanent damage. Overheating can be caused by a malfunctioning fan, old thermal paste, or a clogged heatsink.

6. Defective Expansion Cards

Graphics cards, sound cards, and other expansion cards enhance a computer’s capabilities. However, if they’re defective or not seated properly in their slots, they can cause the computer to shut down.

7. Hard Drive Failures

The hard drive is where all data is stored. If it starts to fail, it can cause a range of issues, including the beep-shutdown problem. Clicking noises, slow performance, and disappearing data are other symptoms of a failing hard drive.

8. External Devices Causing Interference

Sometimes, peripherals like keyboards, mice, or USB devices can malfunction and send erratic signals to the computer, causing it to shut down. This is especially true for devices that draw power directly from the computer, like some USB devices.

9. A Defective Motherboard

The motherboard is the main circuit board housing the CPU, RAM, and other critical components. If it’s defective, it can lead to a host of issues, including the computer beeping and then shutting down. Signs of a failing motherboard can include visible damage (like burnt areas), random system crashes, and failure to boot.

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.

• A very short beep indicates a problem with the motherboard. It could also indicate problems with your internal storage. (BIOS AWARD).
• A long beep followed by three consecutive short beeps indicates a problem with the graphics card configurations. 
• A 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.

Here’s a table based on the computer beep codes and their meanings:

Beep Pattern	Problem Indicated
Very short beep	Problem with the motherboard or internal storage (BIOS AWARD).
Long beep followed by three consecutive short beeps	Graphics card configuration issue.
Short beep followed by three consecutive longer beeps	System memory issue.
Beep, pause, beep, pause, two consecutive beeps	CPU (central processing unit) problem.
Three beeps, pause, three beeps, pause, four beeps	Video memory problem.
Longer beep followed by nine small beeps	ROM issue (BIOS AWARD).
Three beeps, pause, four beeps, pause, beep	Graphics card issue.
Four beeps, pause, three beeps, pause, beep	Problematic system memory.
Five brief beeps	CPU malfunction.
Long, constant beeps	System memory problems.

This table provides a clear and concise reference for diagnosing computer issues based on beep codes.

How to Fix ‘Computer Beeps Then Shuts Off’ Problem? 4 Methods

Method 1: Basic Setps

A major hardware fault may occur if the computer makes a beep sound and the system fails to boot properly.
