Imagine you have turned on your machine, and it starts making a noise like a jet taking off.
There can be a couple of culprits behind this irritating noise.
No computer is completely silent.
But it shouldnt make a noise like a lawnmower.
Are you also hearing strange noises coming from your box?
Some noises are common and completely fine with some computer components.
But unusual noise needs some extra attention.
Buzzing sound can hurt your PC components day by day and may require fixing.
I faced the same issue that required lots of research later.
I found particular reasons and solutions as well.
Stay with me to know the reason and the proper solution to fix it.
Why My Computer is Buzzing?
These components make some noise when running, but they shouldnt be annoying.
In most cases, there could be a hardware problem behind it.
Computers are meant to make some noise.
When they make abnormal audible noise, there should be a reason behind the buzzing.
Buzzing sound can come from the inside of a desktop or laptop.
It can be an electrical buzz or a whining sound.
Identifying the actual component in a laptop can be trickier than a desktop.
I have researched and identified the reasons behind the buzzing.
Fan gets dirty over time and starts making noise.
When it gets dusty, it cant cool the PC components properly.
As a result, the casing fan starts spinning faster and begins buzzing.
Additionally, when the fan becomes dirty, the airflow gets restricted.
The fans dont get enough air supply.
Therefore it starts running quicker and makes audible noise.

Loose screws are a common issue with desktops.
A loose screw can misplace a casing fan.
As a result, it starts vibrating and makes noise.
Loose components can continuously hit the structure or other parts leading to a buzzing.
Loose or dislocated wire can hit the fan resulting in a buzzing.
CD/DVD ROM spins very fast when they are in operation.
It often makes noise while reading.
But the sound should be reasonable.
Faulty CD/DVD ROM can create buzzing while running.
Sometimes damaged ROM can start crackling noise.
CPU-intensive processes can make the CPU work under heavy pressure.
The CPU gets hot when its overloaded.
In that situation, the CPU fan starts running faster to cool down the CPU.
A high-speed fan creates a buzzing sound.
Continuous overloaded CPUs can make noticeable noise.

Hard disk drives or HDDs run at high speed when in use.
When running at full speed, it makes a whirring sound.
Excessive heat can damage an HDD.
A repetitive clicking noise is a sign of a damaged HDD.
Continuous buzzing and humming sounds can make the HDD stopped working.
Computer electronic devices contain coils, mainly in GPUs.
During intensive use, it produces noise.
It starts vibrating at one point, making a buzzing sound.
The power supply provides power to every component of a computer.
An overworked PC needs more power to run.
In that case, the power supply has to supply more power to the parts.
This results in the power supply gaining more heat.
Modern power supplies or PSUs have a fan in them.
The fan starts spinning to cool the power supply, making noticeable noise.
Connecting a computer with another one makes a high-pitched noise.
The noise comes from the onboard modem speaker.
The sound only comes while establishing a connection with another computer.
Computer speakers receive interference from other electronic devices.
Its pretty normal to hear cracking sounds when turning on or off.
Hearing noise continuously can occur due to electromagnetic interference.
It can degrade or make complete failure over time.
Its also completely normal when its in sleeping mode.

Not fixing buzzing at the primary level can cause heavy damage to your system in the future.
Buzzing is a sign of a defective component.
Not taking proper measures can lead to failure or complete destruction of the component.
Fixing computer buzzing issues is easier on a desktop compared to a laptop.
Here are the ways to fix computer buzzing effortlessly:
1.
Clean casing fan
Dust on the casing fan commonly causes buzzing.
Clean the fan using a dust blower or electric duster.
You should avoid any hair dryer or air blower that spreads hot air.
Hot air can damage the internal components of the PC.
If it’s possible for you to launch the casing fan, it will be easier to clean it.
Use tissue or microfiber cloth and carefully clean the fan.
Maintain proper airflow to the fan to avoid buzzing issues.
If there are any obstructs, remove them from the airflow path.
Dont keep it beside a wall that restricts airflow to the fan.
If you are using a laptop, give it enough space to pass the air.
Tighten screw and wire
Loose screws in the fan or other components can create noise.
Open your PC casing and look for the loose screw.
Once you find the area, tighten the screw.
Place the fan or component in the right place and peek if its vibrating.
Constant vibration can misplace the component again.
Loose wire can hit other components and make a buzzing sound.
Secure the wire so that they dont hit other parts.
If necessary, tie the wire,
so they dont lose again.
Clean CD/DVD ROM
Dust can affect CD/DVD ROMs and make noise.
initiate the component and clean the inside of it.
If there is any CD/DVD inside the ROM, bring it out and check for scratch.
Scratch can create buzz while running.
Clean it with a soft cloth or tissue.
If the buzzing remains, change the CD/DVD if you find any issue.
Re-insert the CD/DVD ROM and verify if its solved.
If the problem continues, you may need to change the component.
Change HDD
Every HDD has a timespan.
But it gives signs before complete damage.
The failure can happen from a minute to a month after passing a sign.
Repairing the HDD is quite impossible.
So, you should back up your data before that happens.
Change your HDD if Its wholly damaged.
Claim the warranty if you have one.
Reduce CPU stress
Intensive tasks can create pressure on the CPU.
you could close any unwanted task or background apps to reduce the CPU stress.
Heres a way to reduce CPU stress:
Also, harmful malware can increase CPU stress.
If you find any malware, remove them from your box.
Fix the coil whining issue
If the whining comes from a GPUs coil, dont give it much stress.
Its difficult to replace only the coil from a component.
But if you have a warranty on that component, you should claim it.
Buzzing coming from a power adapter can lead to a hazardous situation.
Its best to change it as early as possible.
Change the power supply with an upgraded one.
If the buzzing sound comes from the fan, clean it properly, and it should be solved.
Fix speaker issue
Other devices electromagnetic fields can create noise in the speaker.
To confirm, test your speaker by keeping it far from other devices.
If you find the unit behind the reason, you’ve got the option to keep it elsewhere.
Or if you still face problems with the speaker, buy a new one.
FAQs
Why is my laptop buzzing?
Buzzing sound can come from a laptop if the cooling fan isnt getting enough space or not cooling accurately.
Overuse or not shutting down after work can create buzzing issues.
Why is my CPU making noise and not starting?
Why does my PC make a buzzing noise when I turn it on?
Conclusion
your rig is precious to you.
But strange buzzing sounds can create problems with the components of your beloved computer.
Ive mentioned every reason and the solutions along with it.
I expect this article will help you find the reason and solve the problem comfortably.
Have a fantastic day!
