Is your computer beeping whenever you start it? You may think it’s normal, until one day your computer refuses to start.
Your computer is signaling you its problem by making this beeping sound. You can avoid your CPU from shutting down permanently by understanding what this beeping means and take proper steps to fix the issues.
In most cases, computer beeping is normal when you have a display on your monitor, and you can see the CPU booting. The concern arises when there’s constant computer beeping or when you hear solid, loud beeps.
Computer Beeping – What It Means?
Computer beeping is defined as a series of PC beep codes played by your computer’s operating system. It indicates that your computer is not able to pass the Power On Self Test (POST).
Your system is not able to pass the POST because it has encountered a system case issue. The beep sound from the CPU is telling you that specific systems have faced errors during the initial startup test.
The POST is default in every computer OS. It is a test that runs across computer hardware when you start your PC.
The POST sends signals to the software run by hardware, which includes your keyboard, mouse, graphics card, network interface card, sound card, serial port, power supply unit and hard drives, among others.
So, the beeping means specific computer hardware is not working correctly. The POST is signaling the PC beep codes to communicate a system error.
Determining Why Computer Beeps Constantly When Switched On
The POST, however, can’t disclose if it’s a specific hardware or a series of hardware that have faced errors. You need to figure it out yourself. Here’s how you do it.
To identify the system error, power on the PC, or restart it if it’s already on. Listen to the beeping carefully and make notes as follows:
- Constant beeping often relates to memory problems or hard drive system errors.
- Listen to the beeping again by restarting your computer. Your motherboard or BIOS chip has faced errors if you hear three beep codes distinctly with a pause after every third beep.
- A very short beep also indicates motherboard issues.
- Long beep, followed by three sequential short beeps – your graphics card configurations are erring
- A pause between three beeps repeated twice, and ending with four beeps – there’s an issue with your video memory
- Single beep, pause, and single beep, followed by two sequential beeps – this pattern means the error is linked to your CPU
Also, if your PC is beeping after the OS has launched, then your CPU is overheating.
You should address this beeping immediately as it may damage your computer entirely within moments.
How to Fix Computer Beeping?
Based on what the beep codes indicate, you can fix the beeping sound coming from your computer.
If the beeping is post-OS launch,
- Clear out space near your CPU
- Allow the system fans to run freely by opening the CPU and cleaning the dust or dirt accumulated on fan blades
- Increase the cooling externally by moving your PC close to an AC vent or by running a portable fan near the CPU
If the beeping indicates system case issue linked to the graphics card or video memory, replace the video vertical retrace adapter. Repair the graphics card with professional assistance or replace it with a simulator.
When the beep codes indicate a motherboard or BIOS chip issue, dry-clean the motherboard to solve circuitry errors. If this doesn’t stop the beeping, consider replacing the motherboard or BIOS chip.
