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.
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.
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.
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. It can assist you in performing recovery from a logically failed, damaged, or corrupted hard drive.
Download, install, and set up the software carefully on your PC or any other PC in working condition. Once the software is ready for use, follow the steps below:
Step 1: Select a Location:
Launch the program, and the software will display the available list of the location for scanning. Select the hard drive and tap on the Start button at the bottom of the software window.
Step 2: Scan the Location:
By default, Recoverit will perform an All-Around Scan of the hard drive to look for the lost and deleted files. The scan results will start appearing on the screen as the scan moves forward.
Usually, it only takes a couple of minutes to finish the scan. But if there are many large-sized files on the drive, the scan will take a while to complete.
Step 3: Preview and Save:
Once the scan finishes, start selecting the files that you want to restore and have a preview. You can choose multiple files and hit the "Recover" button to save them on your system.
Hopefully, the steps we provided to fix the beep issue will come in handy, and you will be able to get rid of the cause of the problem.
In the end, when you can't find a solution to the problem, data loss becomes inevitable. However, whether it is no beep on startup issue or the system has failed, Recoverit Data Recovery software serves as the perfect solution to data loss problems. With the help of this professional tool, you can ensure that not even a single piece of data will get lost from your computer. Don't forget to tell your friends and family about Recoverit.
