In fact, if you hear strange noises coming from your PC, there are cases where the HDD is malfunctioning.
However, depending on the sound, there may be no particular problem, so please check this article to find out the cause of the sound.

We also explain what to do if your PC fan is noisy or suddenly becomes noisy, so we hope you will find it helpful.

Causes and solutions for strange noises such as “jijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijiji

If you hear abnormal noise such as "Jijiji", "Crispy", "Gee", etc., please check the following causes and solutions.

• For hard disk seek sounds
• In case of hard disk failure or malfunction
• If your SSD makes strange noises such as jijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijiji

For hard disk seek sounds

If you hear sounds such as "jijiji", "crisp", "ji", etc., the probability of the hard disk's sequence is high, and in that case there is no problem.

"Seek noise" is the sound that occurs when a hard disk reads and writes data.

However, if the sound is too loud or suddenly becomes bothersome, you may want to suspect a problem with the hard disk and perform an error check.

[How to check hard disk errors (Windows)]

1. Select the folder mark (Explorer).
2. Select "PC".
3. Right-click the drive you want to check for errors in "Devices and Drives".
4. Select Properties.
5. Select the Tools tab.
6. Select "Check" for "Error Check".
7. When you see "This drive does not need to be scanned," select "Scan Drive."
8. When you see "Your drive was scanned successfully," select Close.

If there is nothing wrong with your hard disk, but you are concerned about the seek noise, there are silent cases available, which may help reduce stress caused by the noise.

In case of hard disk failure or malfunction

Abnormal noises may also occur if the hard disk is malfunctioning or malfunctioning.

In such cases, it may be possible to improve the data by defragmenting the HDD.

Defragmentation is an abbreviation for "defragmentation," and it means to organize the state in which data is stored separately on the hard disk (remove the fragmentation of the hard disk).

When data is stored separately, the PC becomes slow because it has to read data from various places in order to open a single file.
Therefore, the problem may be resolved by defragmenting it.

It is also a good idea to perform an error check to confirm any problems.

However, if a hard disk failure or malfunction is suspected, data may be lost, so we recommend that you back up your data as soon as possible.

[How to defragment a hard disk]

1. Select "Start (Windows mark)".
2. Select "Control Panel" from "Windows System Tools".
3. Select "System and Security".
4. Select "Defragment and Optimize Drives" under "Administrative Tools".
5. Select the appropriate drive.
6. Select "Optimize".
7. When "OK" is displayed in "Current status", select "Close".

If your SSD makes strange noises such as jijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijijiji

If you use SSDs instead of hard disks but make noise such as "Jijiji", "Crisp", "Boon", you may be affected by BIOS options.

For example, in the case of DELL notebook PCs, if the BIOS C-State option is enabled, a certain voltage is applied to the SSD, which may cause strange noises such as jijijig, buzzing, etc.

Therefore, turning off this option may help. (BIOS menu contents vary depending on the manufacturer.)

There are also cases where the sound has been reduced by changing the OS's power settings to energy saving mode.

[How to set the power settings to energy saving mode (Windows)]

1. Select "Start (Windows mark)".
2. Select "Settings (gear mark)".
3. Select "System".
4. Select "Power & Sleep".
5. Select "Additional power settings" under "Related settings".
6. Select "ECO" from "Show additional plans" in "Power Options".
7. Set the details and select Save Changes.

If you are using an SSD and still hear noise, try changing the settings above.

Causes and solutions for strange noises coming from your PC

If you hear unusual noises such as "squealing" coming from your PC, you may suspect that your HDD is malfunctioning.

If your HDD is damaged, you may lose data, so it is best to back it up as soon as possible and replace it with a new HDD.

If you want to perform error checking or defragmentation, please do so after making a backup.
You can check error checking and defragmentation methods from the following items.

Causes and solutions for unusual noises such as “rattling” and “gurgling” coming from your PC

If your PC makes strange noises such as rattling or whining, the following may be the cause:

• Cables are tangled in the fan
• Foreign object is stuck in the fan

For example, if you hear a rattling or gurgling sound that sounds like it's stuck, the cable may be tangled in the fan.
In this case, you may be able to find the cause by opening the PC and checking the wiring.
If the cables tend to get tangled, it is a good idea to use a cable band to tie the wires together.

Also, if you hear a rattling or gurgling noise, there may be a foreign object stuck in the fan.
Check to see if there are any foreign objects between the fans, and if there are any, clean them and remove them with tweezers.

Causes and solutions for abnormal “whinn” noise from PC

If your PC makes a whining sound, it may be the operating sound of your CD, DVD, or BD drive.
This is the reason why your PC makes a whining noise when you turn it on or wake up from sleep. In such a case, it can be said that there is no particular problem.

It may also be the sound of the cooling fan running because the PC is overheating.
If you hear a constant whining noise or feel it's too loud, check to see if there's dust or dirt built up in the fan, or if your PC is overloaded. please. If cleaning the fan doesn't help, you may want to check to see if you're working with the vents blocked by surrounding items.

Causes and solutions for abnormal buzzing noises from your PC

If your PC makes a "buzzing" sound, it may be the sound that comes from powering up the desktop when you turn it on.
If you hear this kind of noise when starting up, it is within normal range.

Also, in this case, the sound may be caused by the cooling fan running because the PC is overheating.

Try removing dust from the fan and checking to see if it is getting too hot.

If the PC fan makes an abnormal noise due to shaft misalignment or shaft vibration.

If dust accumulates on the PC fan, the shaft may become unstable, which may prevent the fan from working properly and cause abnormal noise.

In this case, it would be a good idea to remove dirt and dust from the fan and check for deterioration of the parts.

If the axis of the fan is misaligned, repairs will be required.

If your computer's fan suddenly becomes noisy

If your computer's fan suddenly becomes noisy, the following may be the cause:

• Dust has accumulated on the fan or vents.
• PC is overheating due to load
• Motherboard/CPU malfunction

The solutions for each cause are listed below.

Dust has accumulated on the fan or vents.

If your PC's fan suddenly becomes noisy, it is also possible that dust or dirt has accumulated in the fan or vents.
First, check to see if any dust has accumulated on the fans or vents, and then clean them.

To clean dust from fans and vents, turn off your computer and remove the dirt with compressed air or a brush.
It is also useful to use tweezers if the area near the fan is clogged with dust.

When cleaning, be careful not to damage or lose parts, and remove static electricity before cleaning.

PC is overheating due to load

If your PC's fan suddenly becomes noisy, it may be because your PC is overheating due to the load.
In this case, check the CPU usage in Task Manager and, if necessary, terminate the process that seems to be causing the problem.The problem may be resolved.

[How to check CPU usage with Task Manager]

1. Press the "Ctrl" key, "Shift" key, and "Esc" keys at the same time to display the task manager.
2. Select the Performance tab.
3. Select "CPU".
4. Check "Usage".
5. If you check the CPU usage and find it high, it may be a good idea to end unnecessary processes in the "Processes" tab.

Motherboard/CPU malfunction

If your computer's fan suddenly becomes noisy, there may be a problem with the motherboard or CPU.
It is also possible that the temperature inside the PC has risen due to a failure in the CPU, causing the fan to spin at high speed and become noisy.

If your CPU is malfunctioning, you may experience other symptoms such as repeated reboots or freezes.

In the case of a motherboard failure, problems may occur such as the screen not displaying or the BIOS not starting even when the power is turned on.

If these parts are damaged, they will need to be replaced.

There is also a possibility that the fan itself has malfunctioned, in which case it will need to be repaired.

Summary of causes and solutions for unusual noises from your PC, and what to do if the fan is noisy

This time, we explained the causes and solutions for abnormal noises coming from your PC, as well as what to do if the fan is noisy.
There are various sounds that come from a PC, but some of them are like seek sounds that occur even when operating normally.
It is necessary to determine whether the abnormal noise is due to a problem with the hard disk or main body parts, or whether the noise is within the normal range and take appropriate action.

If the fan is noisy, first check the condition of the vents and fan and try cleaning them to remove dust.

If your PC is in normal condition and you are really concerned about the sound, it would be a good idea to take measures such as using a silent case.
