In this article we will try to teach you How to Troubleshoot Startup Beeps on PC. POST or Power-On Self-Test is a diagnostic test sequence that the system BIOS (Basic Input Output System) runs as soon as you turn on a PC or laptop. The POST checks the necessary hardware like processor, RAM, internal hard drive and others before booting the operating system. If POST finds everything OK, the operating system boot process begins; However, if the attached hardware is faulty, defective, or not found, the BIOS will display an error message/code indicating the problem with a series of coded beeps. Each error has its beep code, which also differs from BIOS to BIOS.
For example, a short single beep may be normal for some computers when they start up. However, variations in beep length (short, long, or continuous) or number of beeps (0 to 12) should be considered a warning. A computer making random beeping sounds indicates that something is wrong with the system hardware. Below we have mention the steps to repair PC Beeps On Startup Issue.
Ways to Fix PC Beeps On Startup Issue
Check Connections
Make sure all cables including power cords and other connections are intact. Check all the cables connected to your CMOS battery, RAM, graphics card, keyboard, storage drives like HDD, internal SSD, USB flash drive, etc. and other components. If one or more cables are damaged, the situation may arise – your computer does not beep. Also, make sure all wires are connected properly or connections are tight.
Remove All the USB Devices
If there is no beep, you can try unplugging all connected USB devices, including your external hard drives, portable printers, USB hubs, and more. Then try restarting the PC to get it to boot up. Next, connect your devices one by one to identify the faulty device.
Check Power Supply Unit
Sometimes power issues can cause no post-beep. If the power supply is insufficient or the flow of electricity is frequently interrupted, your computer will not boot, there will be no beeps.
Check the power cords and power adapter to see if they are working normally. You can try replacing the power supply with a new one with a similar output, which will help to determine if the problem is related to the power supply.
Remove RAM
If you install two sticks of RAM on your computer, you can try removing a module from the computer and running the PC to see if it can boot. If not, put the RAM stick in a different slot and start the computer. Do the same for another RAM stick to troubleshoot if the no beep at startup issue is related to the computer memory.
Check CPU and Its Fan
If your CPU is not installed properly or the plastic protector is not removed after installation, the PC will not boot. You should make sure the CPU works well and you remove the plastic protection properly.
Also, you should check whether the CPU fan can work properly. If you cannot hear the sound of the fan running, the motherboard is preventing the system from booting to prevent the PC from overheating.
Clear CMOS
Clearing the CMOS can reset the BIOS to its default settings. You can read system or motherboard user manual or contact support team to learn how to reset CMOS on motherboard.
