3 beeps codes is a system board failure and 5 beeps is a CMOS battery failure.

Ensure you backup all imp data on the system first.

Update the BIOS if possible - restart the system and check.

Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us. These are onboard diagnostics and they might possible pick some error if the hardware is not functional.

If the 5 beeps issue persists, then download the service manual from the above link - remove and reseat the CMOS battery and check. Or replace the CMOS battery and check.

If the issue is unresolved, then I would suspect a motherboard failure.

My personal suggestion is for you to invest your money on a new machine than to repair this system. However, that is your discretion.

Let us know if you have any other queries.


Hi Mayur,

Welcome to the Community,

Beep sounds can be used as diagnostic indicator.The computer might emit a series of beeps during start-up if there are errors or problems. This series of beeps identifies a problem and is called a beep code.

Refer to this table below which illustrates the beep codes and the possible problem:

Beep Code Overview
BIOS ROM checksum failureSystem board failure, covers BIOS corruption or ROM errors.
No Memory (RAM) detectedMemory or Memory slot failure
  • Chipset Error (North and South bridge error
  • Time-Of-Day Clock test failure
  • Gate A20 failure
  • Super I/O chip failure
  • Keyboard controller failure
System board failure
Memory read / write failureMemory failure
Real Time Clock (RTC) power failureCMOS battery failure

What Does the Long Continuous Beep Sound Mean on My Computer?

The type of beep your computer makes when starting up is meant to explain your computer's status. One long, continuous beep generally means that there is a hardware problem – often memory related – that can prevent your computer from starting up at all.

If you can't start your computer properly, you'll need to take a look at the physical hardware inside your machine. In a best-case scenario, the computer can reset and return to normal functions. In a worst-case scenario, your computer is experiencing a major hardware malfunction that will require repair or replacement.

Try a Reboot First

Before tearing the computer apart to inspect the hardware, try a simple reboot. If you can access the menu and run a normal restart, go ahead and execute the process. If the computer is no functional while making the noise, press and hold the power button until it shuts down.

After forcing a shutdown, remove your power cord and the battery, and then wait for a full two minutes. Return the power and test the computer. If the noise persists, you have a potentially serious problem to address.

If the computer is beeping on startup, without any hesitation, the issue is most likely a hardware and memory problem.

Check the Battery

As a last ditch effort, always check the battery level or make sure that your computer is securely connected to a power source. Press all the plugs to snug everything up if needed. A loose power connection can drain the battery and many computer making beeping noises are only a warning that power is lost and a shutdown is looming.

If the power is solid and the battery is charged up, move on to more intensive troubleshooting processes. With any luck, the problem is resolved by snugging up your power cord.

Bad Memory Sticks

Although a long beep can mean you have hardware issues, this doesn't necessarily mean that your hardware has gone bad. It could simply mean that it is loose or not seated correctly. Remove and replace your computer's memory securely in their slots to try to fix the problem.

If this doesn't work, and your computer has more than one memory stick, try inserting only one stick at a time; it could be that one stick has failed, while the other is fine.

Troubleshooting Your Chip

Your computer's motherboard has a BIOS chip installed for the memory and processing. You must remove the protective panel to actually view the chip and determine the manufacturer. Turn off the power and make sure your computer is shut down before pulling the protective panels to access the motherboard.

Write down the company name and perform a quick search to access the troubleshooting codes. Each company uses different computer beep codes to determine specific problems. Look for the continuous beep in the BIOS chip manufacturer troubleshooting guide to determine the issue. Typically, the beeps happen in a coded sequence. When you hear a continuous beep, it is possible that there exists an overheating CPU or another major issue.

After determining the problem, you can attempt to fix the computer yourself or you can take it to a professional repair service.

How to Fix a Beeping Computer With a Black Screen

By Timothy Smithee

When the computer cannot use the screen, it may use beep tones to indicate a problem.

When a personal computer starts, it runs a Power-On Self Test (POST) to check that various hardware components are working correctly. If problems are detected, the computer will not start. This test runs before the computer is ready to display anything on the monitor, so if any faults are found, the computer will beep to indicate an error. Basic troubleshooting steps can often identify common problems and isolate defective components that may cause a computer to beep.

Common and Easily Fixed Beeping Computer Problems

Check the keyboard to ensure that there are no stuck keys and no keys are being held down. Sometimes a keyboard drawer can press a key against the underside of a desk. Run your fingers over the keyboard to free any keys that may be stuck. If a drink was spilled on the keyboard, replace the keyboard with a new one. Try to start the computer again after completing this and each of the following steps.

Check all cables connected to the computer and make sure they are fully plugged in. Inspect each cable and securely connect or tighten cables as required.

Remove any objects blocking the computer's air vents. If dust has accumulated in any vent, vacuum the exterior vents and carefully vacuum dust from the heat sinks and vents inside the computer.

Disconnect external devices such as printers, USB sticks and hubs, remote receivers and external drives. If the computer starts without external devices connected, one of these components may be defective. Reconnect them one at a time to identify which device is defective.

Beeping Computer Problems Due to Internal Components

Ensure that internal hardware added to your computer recently, such as additional memory or a video card, is installed correctly. Turn off the computer, then remove and re-insert the new hardware ensuring that each component is firmly seated in its slot.

Remove new internal hardware. If the computer starts without the component, it may be defective or incompatible with your computer.

Remove and re-insert all internal connectors and cards, including the memory but not the CPU.

If more than one memory card is installed in your computer, troubleshoot each card one at a time. Make sure each card is fully seated in its designated slot.

Disconnect all internal devices including hard drives, expansion cards, optical drives and card readers. If the computer starts without internal devices connected, one of them may be defective. Reconnect each device one by one to determine which one is defective.

Advanced Troubleshooting for a Beeping Computer

Listen and note the beeps. For example, you might hear one long beep, two short beeps, a pause, another long beep and two short.

Find the user manual for your computer or go to the support website for your computer manufacturer or the motherboard manufacturer if your computer is custom-built.

Look up "POST beep codes" and diagnostic meanings that apply to your computer. If the beep code points to a problem with the motherboard, you may need to replace the board. If the code indicates a defective component but the component is working, a defect on the motherboard may be causing an incorrect beep code.



  • Some computers beep once or twice as part of their normal start up.
  • If a computer will not start when a USB stick is inserted but it starts without the stick, update the Boot Priority settings in the BIOS so that the default boot device is the hard drive.
  • If an internal or external device appears to be defective, test it using a different cable to determine whether the fault is with the device or the cable.


  • After each attempt to start the computer, turn it off and unplug the power cord before proceeding to the next step. For laptops, remove the battery.
  • When working inside the computer case, touch a bare metal part of the case before touching any of the components inside.

How To Fix Dell Laptop That Beeps or Keeps Beeping - Dell Beep Codes - Computer Beeps

Hearing random beeps from my laptop at times


There's the specs. anyways yes, the beeping is completely random. there's been no identifiable pattern as to what causes it or when it happens. If this helps any, I had to get my hard drive replace due to it becoming faulty and my laptop wouldn't boot up. After the new drive was put in, It started to sound these beeps as I have described, and they only happen for a split second. I've checked the event log over and can't say I see anything possibly related (aside from a whole mountain of error logs that seem to be to do with my printer, which was installed on my laptop before my hard drive went faulty).


Edit: On another sidenote, I checked Speccy again after a bit of gaming and noticed my laptop's temperature ratings were looking "not so hot" Attached File  CPU overheat..PNG   55.72KB   1 downloads
