No posts, no beeps, fans spinning on PC [FIXED]

This article will introduce the solutions that users can take when there is no response when booting, the screen is black but the fan is running. The motherboard is not beeping, which could indicate a hardware issue, the report said. In this case, the user can try to reconnect the internal components, check whether the power supply is normal, or consider replacing the faulty part. Diagnosing and resolving problems promptly is key to ensuring your computer operates properly.

In computer terminology, POST refers to power self-test. Every time the computer starts up, a series of system tests are automatically performed to ensure that the hardware and software are functioning properly. If any of these tests fail, the computer will stop the startup process.

Fix the problem of unable to power on self-test, no beep sound, and the fan spinning on the computer

When your computer fan is spinning but there is no beeping sound, you can try the following suggestions to solve the problem of not being able to boot.

Check all cable connections

Check the status of the QLED indicator

Clear CMOS value

Check your memory module

Removing the external graphics card (if applicable)

Reseat the CPU

Flash Basic Input and Output System

The problem may be with your PSU

Your motherboard may be faulty

Contact bracket

Below, we explain all these fixes in detail.

1] Check all cable connections

This problem may occur when assembling or upgrading hardware yourself, but other users may also encounter it. Turn off the computer and check all cable connections to make sure they are tight.

2]Check the status of the QLED indicator

Usually, motherboard hardware failure will cause different beeps, and each brand of motherboard has its own unique audible alarm.

The QLED indicators on the motherboard are critical hardware components such as CPU and RAM. When they light up, they indicate that a specific hardware problem has been detected. You can use these lights to quickly diagnose computer problems. Checking whether the QLED indicator light on the motherboard is on can help you locate the problem faster, thus reducing troubleshooting time.

3]Clear CMOS value

It is recommended to try clearing CMOS to solve the problem. Turn on the computer, take out the coin-shaped CMOS battery, wait a moment and reinsert it. Restart your computer to see if the POST issue is resolved.

It is also possible that the cmos battery is dead. Get a new cmos battery and see if that helps.

4]Check your memory module

The problem of unable to POST and no beep sound may be related to your memory. If your PC has multiple memory sticks, one of them may be faulty. To check this, open your computer case and remove all memory modules. First, clean the memory modules and memory slots. Now, just insert one memory stick into the memory slot and turn on the computer at a time. Test the memory module by inserting it into each memory slot. Turn on the computer every time you plug it into a memory slot.

If you have multiple memory sticks, you can also try different combinations. For example, if you have two RAM sticks and 4 four RAM slots, you can try different combinations, such as inserting RAM 1 and RAM 2 into slots 1 and 2, 2 and 3, 3 and 4, etc.

5]Remove the external graphics card (if applicable)

Remove the external graphics card (if applicable) and turn on the computer. If successful, the problem may be with the graphics card or the cable that connects the graphics card to the computer. It's also possible that your graphics card isn't installed correctly.

You can test the functionality of your graphics card by connecting it to another computer. However, the GPU should be compatible with that computer's motherboard.

6]Reseat the CPU

Reseat your CPU. If you upgraded your CPU or built a new computer, it's possible that the CPU isn't seated correctly. Open the computer case and gently remove the CPU. Now, gently put it back into place. Also, look at these pins. If a pin is bent or damaged, you must fix it.

7]Refresh BIOS

This solution is for users who have upgraded their computer hardware. If you have upgraded your memory or CPU, you may need to flash its BIOS to the latest version to support the newly installed CPU or memory.

Some motherboards have a dedicated button to perform this operation. You can flash your BIOS without CPU and RAM. Remove the CPU and RAM. You need another working computer. Download the latest version of BIOS from your computer manufacturer's official website.

Now, copy that BIOS file to a USB flash drive with FAT 32 file system. The BIOS file should be in the required format. Now, provide continuous power to the motherboard through the PSU and connect the USB flash drive to the dedicated USB port on the motherboard. Press the button to refresh the BIOS.

This is the general method of flashing the BIOS. This method may vary depending on your motherboard manufacturer. Therefore, we recommend that you refer to your motherboard’s user manual and follow the correct method to flash your computer’s BIOS.

Also, please note that power should not be interrupted while flashing the BIOS, as this may cause the motherboard to malfunction.

8]The problem may be with your PSU

Another cause of this problem is that the power supply unit is not supplying enough voltage to the motherboard. If there is another PSU available, you can connect your PC to that PSU and check if the problem occurs. This will let you know if your power supply unit is faulty.

9]Your motherboard may be faulty

There may also be a problem with your motherboard. Your motherboard may be faulty or dead. You will need to contact a professional computer repair technician to confirm.

10]Contact Support

If you have tried everything within your scope to resolve the issue, take your computer to a professional computer repair technician who can troubleshoot and resolve the problem.

that's all. I hope this helps you.
