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
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.
