Motherboard no post, no beep, or no display is a common issue on your computer. If you are bothered by the issue of no post beep on startup, what should you do? Go to read this post from MiniTool and you can find some ways you should try to troubleshoot the issue. As well, how to keep the PC data safe and how to recover files from an unbootable PC are introduced.
No Post, No Beep On Startup, or No Display
When booting your computer, the machine will perform a power-on self-test (POST) to check your hardware including the processor, RAM, hard drive, and others. If POST finds everything is OK, the Windows operating system will load successfully.

However, if there is something wrong with the hardware, there will be an error message or code in BIOS. But if the computer BIOS encounters a problem, there is no error code/message but beep codes appear to notify you. Each error has its beep code that may be different from BIOS to BIOS.
You can check if POST can work by removing the graphics card and booting the PC. If you hear one or two long beeps, this means POST is working. If no beep appears and the system fails to load, POST isn’t working.
Well then, what should you do if there is no post beep? Don’t panic if your computer won’t post no beeps and you can move to the following part to try some troubleshooting tips.
How to Fix No Post Beep on Startup
Check Connections
Make sure all the cables including power cords and other connections are intact. Check all the cables that are connected to your CMOS battery, RAM, graphics card, keyboard, storage drives like hard drive, SSD, USB drive, etc., and other components. If one or more cables are damaged, the situation may happen – your computer won’t post no beeps.
Besides, make sure all the wires are connected correctly or the connections are firm.
Remove All the USB Devices
If there is no post beep, you can try to remove all the connected USB devices including your external hard drives, printers, USB hubs, and more. Then, try to restart the PC to let it boot. Next, connect your device one by one to identify the defective device.
Check Power Supply Unit
Sometimes power supply issues can lead to the issue of no post beep. When there is not enough power or the power flow is being interrupted frequently, your computer can’t boot no beeps.
Go to check the power cords and PSU to see if they work as normal. You can try to replace the PSU with a new one that has a similar power output, which is helpful to identify if the issue is related to the power supply unit.

Remove RAM
If you install two RAM sticks on your computer, you can try to remove one module from the machine and run the PC to see if it can boot. If not, put the RAM stick to another slot and start the computer. Do the same thing for another RAM stick to troubleshoot if the issue of no beep on startup is related to the computer memory.
Check CPU and Its Fan
If your CPU is not installed properly or the plastic guard isn’t removed after installation, the PC cannot boot. You should make sure the CPU function well and you remove the plastic guard correctly.
Besides, you should check if the CPU fan can work properly. If you cannot hear the sound of the fan running, the motherboard is stopping the system from booting to avoid PC overheating.
Clear CMOS
Clearing CMOS can reset BIOS to its default settings. You can check the user manual of the system or motherboard, or access the support team to know how to reset CMOS on the motherboard. Or, you can go to follow methods in this related article – How to Clear CMOS? Focus on 2 Way. After that, boot your PC and it may boot successfully.
