How to Fix My Computer POST Beep Issue

Summary: If the connected hardware is faulty, defective, or not found, the BIOS states the issue with a series of coded beeps. These POST beeps are warning signs and can be disastrous for the system that can also lead to data loss. Here are few methods to fix the issue and steps to recover data lost to the issue, with the help of Stellar Data Recovery software.


How to Fix My Computer POST Beep Issue

POST or Power-On Self-Test is a diagnostic testing sequence that system BIOS (Basic Input Output System) runs as soon as you power on a PC or laptop. The POST checks the necessary hardware such as a processor, RAM, disk drive, and others before booting the OS.

If the POST finds everything OK, the OS boot process begins; however, if the connected hardware is faulty, defected, or not found, the BIOS displays an error message/code stating the issue with a series of coded beeps. Each error has its beep code, which also varies from BIOS to BIOS.

What Does a Continuous Beep Mean On a Computer?

For instance, a short single beep may be normal for some computers as they boot. However, variation in beep length (short, long, or continuous) or a number of beeps (0 to 12) should be considered as a warning message. A computer making beeping noise randomly indicates that there is something wrong with the system hardware.

And Here’s How To Fix Computer’s POST Beep Issue

Below are some steps that can help you make your system boot successfully and fix computer beep codes issue in all system powered by Asus, Gigabyte, MSI, Asrock, Dell, HP, etc.

NOTE:Now before following the troubleshooting steps, shut down your desktop and unplug it from the socket. In case of laptops, switch it off and then remove the battery. Do touch a bare metal or use anti-static band before touching any component in your computer to prevent static electricity from damaging your system’s hardware.

Step 1: Assess the POST

The first step is to check whether the POST is working properly. Simply pull out the video card and boot your system. If you hear one or two long beeps, it means POST is working. The beep code suggests that the video card is not connected. If you hear no beep and system doesn’t boot, it means the POST is not working.

Step 2: Check Connections

Check if all the cables (power cable and other cables) are connected to the respective hardware device (keyboard, storage drive, video card, etc.) on your computer. Check for any damaged or soiled cable; if found, replace them with a new one.

Check for loose connections and worn out connectors

Also, check for any improper or loose connections in between the connectors of RAM, graphics card, SSD, & CMOS battery. When everything is connected properly – boot the system.

Step 3: Unplug USB Devices

Disconnect all USB devices connected to the system such as a printer, USB hubs, external drives, etc. and then boot the system. Let it boot and then connect the USB devices one by one to identify the faulty device.

Unplug all USB Devices

Step 4: Check Power Supply Unit

No beep sound may indicate power supply issue. Check Power Supply Unit (PSU) and try to replace it with a working PSU of similar power output. This lets you check the system’s PSU status and whether it needs replacement.

Check the power supply

On the other hand – silence, long single beep, or series of short beeps is an indicator of issues with memory. A single short beep means POST ran successfully and your system should be able to boot normally.

Step 5: Remove RAM

If your system is equipped with two RAM sticks, consider removing one and then the boot the system. If the system still doesn’t boot, switch the RAM stick to the second slot and boot again.

Disconnect the RAM or Swap the RAM to different slot

Step 6: Check CPU & its Fan

Check whether CPU is installed correctly and the plastic guard is removed after CPU installation. Remove plastic guard from the CPU if it’s still there. Additionally, check if the CPU fan is up and running when you boot the system. Some motherboard do not boot when the CPU fan is not running to prevent it from overheating.

Check and inspect the CPU fan

Step 7: Check Wires

Check that no wire is going under the motherboard. The soldered components pins on the motherboard can pierce wire insulation. This can cause shorting. Consider moving all the wires from motherboard’s rear tray.

Step 8: Try Clearing CMOS – Refer to your system manual

Clearing CMOS means resetting the BIOS settings to their defaults. Find the user manual of your system/motherboard, or visit support site and contact support team to know how you can reset the CMOS on your motherboard.

Remove and insert CMOS Battery to reset BIOS

After resetting/clearing the CMOS, reconfigure BIOS according to your hardware—only if it is required—and boot the system.

Problem With the Hard Drive?

In case the fault is in your hard drive, you should immediately remove it from the system (do not use the drive to avoid data corruption and data loss). After separating the hard drive from the system, connect it to another working PC via SATA to USB converter and then try to access it via File Explorer.

If you are able to access the drive, backup the data, format the drive, and then restore the data to the formatted drive.

If you can’t access the drive, probably it’s damaged or corrupt.

A logically failed, corrupt, or damaged hard drive requires immediate recovery. Therefore, use a reliable software such as Stellar Data Recovery Professional, which can help you securely recover your files and folders from a formatted, inaccessible, damaged, or severely corrupt hard drive and other storage devices including SSD.

Free download

In case the drive is severely corrupt, use the Disk Image option of the software to create the hard drive’s virtual clone on the system and perform the data recovery on the image file. This saves hard drive from further damage and speeds up the recovery process.

Conclusion

We discussed what POST is, why the computer keeps beeping on startup, and what does a series of beeps mean during the start of the boot process. We also mentioned several solutions that can help fix the computer POST beep issue.

POST beeps are warning signs and can be disastrous for the system and the data. Therefore, it’s critical to fix the issue to prevent further damage to the system, which can affect the hard drive and lead to data loss. However, one can easily recover data by using a data recovery software like Stellar Data Recovery Professional in case anything happens to the connected hard drive due to issues with system hardware or power supply.

No POST screen, No beeps and No display

I have very old motherboard , CPU , power supply.

The rig worked fine for over 5years. Suddenly it stopped booting without any error code and POST screen or video. I disconnected everything and kept bare motherboard with CPU, RAM and power supply on table and powered on, again it fails to boot without any beep codes.

The CPU fan rotates and power supply unit fan rotates and power on led lights up. The CPU gets heated as well. But speaker doesn't emit any beep codes. The speaker is working because previously it used to emit short beep code during POST.

I cleared cmos and still the same results.

When I connect a PS/2 keyboard and turn on the power source, the leds (numlock, capslock, scrolllock) on the keyboard flash for a second. This used to happen even when PC is fine. So, with this can we say the motherboard is fine?

If Ram alone is faulty, I think it emits some beep codes. Might not be ram alone. To support this, I removed ram stick and turned on, still no beep codes or POST. So, might not be RAM alone.

My suspect was either the power supply or the CPU? Could it be CPU fault when no beep codes are emitted?

Finally I opened the power supply, which was long out of warranty. I found a big transistor leaked some red fluid which was gel like and hard. This might have happened long back because it wasn't fresh. So, could it be power supply's fault?

I have no doubles to check which one is faulty. Thanks

EDIT:
I have tested the smps alone connecting the green wire and black wire. When power is connected the fan rotates in smps, meaning it might be ok.

EDIT 2:
I will be getting a new PSU anyway.

  • If there are no beep codes, MB could be faulty.

EDIT 3:
I have thrown up SMPS. And got the MB, RAM, CPU checked in a repair shop and was told that the issue is with MB alone. RAM and CPU are fine. Took the MB to service center and was told they don't service for out of warranty products even if I pay them. Then took the MB to another repair shop, that guy told he will repair it but needs like 3hours and charges around 1 / 5th the original MB price. I said OK and returned back after 3 hrs to see it was booting fine. I asked what was the problem, and he told display IC is damaged and was replaced. Don't know how much that costs but the board works now. Also purchased another SMPS and it is working fine now.

EDIT 4:
Now that I thought the MB has been fixed, I purchased an old refurbished Core 2 Duo CPU (E6750 @ 2.66GHz , 4MB Cache and considerable upgrade from Pentium dual core E2160 @ 1.8GHz 1MB cache) and replaced the CPU. I was shocked to see the same No POST, No beeps , No Display again. I thought the CPU was dead and switched to my old working CPU. To my surprise both CPU s gave the same result No POST, No Beeps, No Display. This time I'm very sure that the problem is with CPU socket. I carefully observed the CPU socket and took a piece of paper and slided through each pin rows and columns. Also couple of pins seemed bent, so I gently moved them to normal position again. And inserted the new CPU and tried again. This time it gave POST and beep successfully. Then I realized that the repair shop guy deceived me. He didn't change anything. All he did was to straighten few CPU socket pins and grab some money telling some sort of technical chip is damaged. Now I'm very sure that the old Power Supply unit is even fine, although I have thrown it away. My bad that I didn't mention that I have opened CPU initially before getting this No POST errors.

I will never open the socket again and suggest the same. Never open old MB CPU socket when there is no need. I will post an answer that helps troubleshooting.

How to Fix No beep Codes, POST, or Input to Monitor On Computer Startup?

Many users have encountered a situation where their computer doesn't start up appropriately, and they can't figure out the reason behind this. While a single beep is a sign that POST is working normally, 2 beeps on startup, no display, more beeps, or no beep are considered warning signs. It indicates a problem with the system hardware that needs rectification as soon as possible.

Here we will explore what does POST and beep codes mean and how you can resolve the issues related to them. Moreover, we will discover how you can rescue your hard drive data from being lost permanently.

Part 1: What are POST and Beep codes?

To understand the no beep on startup or multiple beeps problems, we first need to know about the POST and beep codes. When a computer starts up, it runs a POST, i.e., Power-On Self Test, to check if there is a problem with the system. The moment POST detects a problem, it displays an error message on the screen.

However, if the BIOS encounters a problem but hasn't booted far enough to give the error message on the monitor screen, beep codes are used for notification. It is an audible sound of the error message. The beep codes can be very helpful in determining the root cause of the problem. And if there is no beep sound when the system starts even when you have made unsuccessful attempts to start the computer, it means there is still hope. For that case, consider using the POST test card to see the error in digital form and resolving it.


Part 2: How To Fix No beep Codes, POST, or Input to Monitor Issue?

Let's learn how to fix no POST beep codes issues on a computer.

Step 1: Assess the POST:

The first step is to check if the POST is working accurately or not. To do this, pull out the video card and again try to boot your system. During this operation, if you hear one or two long beeps, it is a sign that POST is working. The beep code suggests that the video card is missing. However, if you hear no beep on startup, it means that POST is not working at all.

Step 2: Check Connections:

At this point, ensure that all the cables, including the power cable and other connections, are intact. Check all cables that connect the keyboard, storage drive, video card, RAM, graphics card, CMOS battery, SSD, and other components. There is a slight possibility that one or more cables are damaged or soiled that is leading to the issue in the first place. Replace them with a new one and see if the problem gets resolved.

Step 3: Remove any disks or USB devices:

When there is no beep on startup, try unplugging the connected disks and USB devices. It includes the printer, USB hubs, external devices, etc. Then try booting the system and allow the system to boot completely. After that, start connecting the USB devices and disks one by one to recognize the faulty device.

Step 4: Reconnect and check power cords:

The next valid step to resolve the no beep on startup issue is checking the power cords and reconnecting them. No beep is often a sign of Power Supply Unit errors. When the computer is not getting enough power or the power flow is being interrupted frequently, the system encounters such problems.

So, check the cords and PSU to see if they are working fine. Try disconnecting the wires and UPS from the computer. Connect the power cables to another outlet for a steady flow. Replace the PSU with a new one as it will help you identify if the problem is with the Power Supply Unit.

Step 5: Identify the beep code:

Perhaps you heard the beep wrong, and there might be other beeps. Hence, identifying the beep code is a crucial step in fixing no beep on startup or more beeps issues.

Here is the entire list of Beep Codes that will have you narrow down the problem and its cause. The beep code information is also available on the motherboard or computer documentation. You can gather all the information you want on the beep codes from the document. After all, the beep codes are meant to be a failsafe for the users to help them identify the problem if the boot process doesn't finish up. If the beep code you hear in your computer is not available, then continue with the troubleshooting steps.

Step 6: Remove RAM:

In some computers, 2 beeps on startup and no display is a sign of RAM error. When the RAM is not detected by the system, it will throw this error, and you will hear two short beep sounds. It often happens when the user has connected two RAM sticks with the system. Consider removing one of them and then boot the system.

If this doesn't work, try switching the RAM stick to a different slot and again try booting the system. Repeat the same with the other RAM stick to resolve the error.

Step 7: Check CPU & its Fan:

Now, once you have checked the connections, it is time to look deeper into the problem. Start by checking the CPU and its fan. If the CPU is not installed correctly or the plastic guard is not removed correctly after CPU installation, then the system will give more beep sounds. So, make sure that the CPU is working fine, and the plastic guard is also removed.

Alongside this, check if the CPU fan is working when you boot the system. So, if you don't hear the sound of the fan running, it means that the motherboard is preventing the system from booting. The motherboard often halts the boot process if the fan is not working to prevent the system from overheating.

Step 8: Check Wires:

If everything other component is working well, then it is time to check the wires. You must have connected the cables inappropriately, or the connection might be loose. Check the cables and secure the connection by firmly pressing each cable.

Step 9: Try Clearing CMOS – Refer to your system manual:

The next fix is clearing the CMOS. It means that you will reset the BIOS settings to default. To do this, we propose that you refer to the system manual or get in touch with the system support team to learn how you can reset the CMOS.

Once the CMOS is reset, you can reconfigure the BIOS according to the hardware, if required, and boot the system normally.

Step 10: Bad motherboard, CPU, RAM, or power supply

If all the above tips failed to resolve the no beep on startup issue, it is most likely that your computer's motherboard, CPU, RAM, or power supply has failed. Hence, the final step will be replacing these components or get your system serviced from professionals.


Part 3: How to recover data what if there is a problem with the hard drive?

In the worst-case scenario, when there is no beep on startup, it might be the hard drive interrupting the system hardware from running smoothly. At this point, the users will get worried, thinking they might end up losing their system data of this. But don't worry; even if you somehow end up losing files, Recoverit Data Recovery software can still help restore all lost and deleted files.

Fix computer no boot no beep no post

Pc starts but no beep is heard and no bios image on screen

Any bad component can cause a no post which seems to be what you have going on. It looks like you have gone through most of the diagnostic procedures but I will post my general no post procedures below just in case something more can be done. Also from experience in retail, motherboards fail far more often than cpu's. In fact after ~10 years in retail, I had only seen a handful of failed cpu's and 1000s of bad motherboards...

 

Make sure you have the computer unplugged from power while removing or moving any hardware...

 

Try 1 stick of ram in 1 slot at a time (remove all other ram sticks). Move it to the next slot until you have tried that stick in all slots by itself. If you still have no post, try a different stick of ram in each slot by itself. If you have issues with the stick in 1 particular slot (a no post for example) the slot may be bad. It is also possible you have a bad stick of ram instead of the slot being bad, in this case the ram stick should cause the same problem all slots.

 

You may have a memory controller issue in which case if you have 4 slots, 2 may not work. With intel it should be 2 slots next to each other channel 1 might be slot 0,1 and channel 2 might be 2,3. Trying with 1 stick at a time in all 4 slots is the best way to test everything.

 

If you never get a stable system with just 1 stick of ram in 1 slot (trying all sticks by themselves) try removing all non-essential hardware to get into bios:

 

Disconnect pci cards, pci-e cards - except a video card unless you have onboard in which case use the onboard video and pull the video card, hard drives, dvd drives, disconnect all usb headers as well. You should only have the power supply, main board, 1 stick of ram in 1 slot, the cpu and cpu cooler connected. You can also plug in a monitor and keyboard. Now try to power on the machine. If at this point you have no post screen or video etc, unplug the computer and pull the stick of ram, power back on and listen for a post fault beep code, you will need to hook up a motherboard speaker to hear any post fault code, if this is a laptop it should be built in.

 

If you get no response next: remove all of the components from the computer case and connect only essential hardware (cpu, motherboard, 1 stick of ram, power supply 24pin and 4pin connectors) outside of the case, place the motherboard on a non-conductive surface, a wooden table will do fine. You can also plug in a monitor and keyboard. Then try to power on again, you can short the power button pins on the motherboard, don't worry this is exactly what the power button does. Just touch a metal item to both power button pins to try to power the mainboard when outside of the computer case.

 

While you have the computer apart, look for blown or bulging capacitors on the mainboard and video cards etc Examples please report any caps you suspect may be bad, you can take a picture and post here if you are unsure.

Beep no post

Hey there, my system will power up but will not give any error beeps or output any video :(

History: My build had been performing well for around 7 months until one night it crashed and would not power on again. I determined it was the PSU and had it RMA'd. Now with the new PSU, my system will power on but will not give any display or error code.

Full Story:I followed this guidebut I'm getting the same results. I breadboardedmy components in order to avoid any possible shorts to the case and worked down the checklist.

* CPU power connector check
* Motherboard power connector check
* Video card fully seated check
* Video card power connectors fully inserted check
* Boot with single stick of RAM/RAM fully inserted check
* CPU installed correctly? (I assume it is, it was working properly before without any tampering)
* CPU fan plugged in check
* System speaker connected check

In addition to the above, I confirmed the monitor worksusing another source and confirmed the video card functions by swapping it into an older box. I attempted switching the video card into another slotas well as swapping the video cardwith one that I can confirm works, both to no effect.

I can confirm that the system speaker works, as booting without RAM will elicit an error message. I have attempted a barebones startup with only the MB, CPU, and a stick of RAM and there were no error tones.

I checked if the CPU was receiving power. All four phase LEDs turn onwhen supplied power.

Finally, when I swapped in my old video card, something interesting happens. During a normal boot, the video card's fan will spin at full speed for a few seconds before reducing to 50% speed for a second before finally falling to an idle speed. When I powered on the card in the current MB, the fan maintains 100% speed and will not fall to a lower speed. Perhaps this indicates an error in the boot sequence?


I would be very grateful if you had any suggestions or insight into this problem. :)
