Computer Is Making Noise Randomly Here is How to Fix it

If you’ve started hearing an excessive amount of noise coming from your computer it might be time to open it up and figure out why it is making that noise.

No computer is completely silent, but when it is making an excessive amount of noise, then something might be wrong and it is good to figure it out before any permanent damage happens.

Diagnose And Figure Out Where The Noise is Coming From


Your PC is most likely making noise from the fans or hard drive. If that’s the case you need to fix it immediately because it could mean that your hard drive is damaged or fans are damaged. The noise could also be coming from your GPU which is usually not a big deal but should still be checked.

A noisy hard drive could mean that your hard drive is starting to get old and it’s at the end of its life. You should immediately transfer the data elsewhere to make sure the data doesn’t get corrupted.

Loud Hard Drive Making a lot of noise

Having noisy case fans probably mean that the fans of your computer are wearing out, this can lead to excessive overheating in the PC which can potentially damage other parts in your PC.

Here is an article I wrote about overheating and how to prevent it. You should check it out if you’re having this problem.

There are many different noises that your computer can be made so in this guide I will be going through the most common noises your PC could be making and how to fix them.

Make sure to read through everything, so you can figure out what noise your PC is making and how you can fix it.

What to Do If Your Computer is Making a Grinding Noise

A grinding noise from your computer usually means that you have a problem with your hard drive.

You can compare this sound to a low grind, click, or buzz. If you hear anything similar to these sounds you need to check your hard drive immediately, and please do not ignore this sound because it’s an indication of a dying hard drive disk.

The first thing you should do to diagnose this problem is to check your driver’s health. You can do this by checking the health of your hard drives using third party applications,

I would recommend using CrystalDiskInfo as this is what I use to check the health of my drive.

Using CrystalDiskInfo to check my hard drives health

As you can see I am using CrystalDiskInfo in this picture to check the health of my hard drive.

Under Health Status, it should say Good, Caution, or Bad. If it is indicating that your hard drive disk is Bad, then you should take action immediately by backing up your saved data and transferring it to a new Hard Drive or SSD.

If the Health Status, states Caution, then you should still backup your data and transfer it over to a new storage device as soon as possible.

When it indicates your hard drive status as a caution, it is still possible that your hard drive has a couple of years of life left before it stops working, but this is also a warning telling you that something is wrong with your hard drive and that you should still take action.

Also, even if it is listed as a caution your hard drive is making a lot of noise, which is telling you that your hard drives are at the end of their life and it needs to be fixed or replaced.

When upgrading to a new hard drive it is recommended that you switched to a faster SSD as the life expectancy is longer, it’s faster, and it won’t make any noise.

The reason for this is that your hard drive is a moving disk on a motor, so it is bound to make some noise.

Whereas an SSD is a computer chip so it has no moving parts, which means it won’t make any noise.

That way you can make your PC even more silent than when it was when you first bought it.

Here is a step-by-step guide on how to fix the grinding noise coming from your PC. I would recommend giving this a quick watch if your pc is making this noise.

How to Fix Loud Whirring Noise From Your Computer

A loud whirring noise coming from your computer is most likely due to your CPU overheating.

When your CPU starts to overheat your case fans will speed up to their max speed in an attempt to cool down your CPU.

you may find that after a couple of seconds or minutes your fans go back to normal speed and the noise goes away.

If this is the case then it’s worth manually adjusting your fan speed, or switching the location of your fan to a more optimized location for cooling.

This loud noise can also be due to your hard drive disk spinning really fast which could be caused by bad hard drive health. If this is the case check the health of your hard drive shown in the previous step.

Another thing you might experience from the whirring noise in your computer is that every time the noise gets really loud and your fans start to speed up, you might experience a black screen.

This is something that happens to me from time to time.

This again is another problem due to an overheating CPU.

CPU on fire

If your CPU is constantly overheating here is an article I wrote on Why Your CPU is Overheating and How To Fix it.

What you should first do to check if your CPU is overheating is to check the temperature of your CPU.

If your CPU is hitting 80 degrees Celsius then it is a good chance that your computer’s cooling system is not very good at keeping your PC cool.

The way to fix this is to either upgrade your cooling system by buying better case fans or switch to water cooling.

If your CPU is running at around 70 degrees while it’s idle then something is again wrong with your cooling causing your CPU to overheat and making your fans work harder, thus making your PC very loud and annoying.

You should start by going into Windows Task Manager to check if any background applications are using a majority of your CPUs energy.

If so, you should either remove the application or cancel it at startup. This will clear up your CPU usage so it doesn’t use as much power, thus producing less heat and allowing your fans to make less noise.

Doing this can also allow you to check if there is any malware working in the background eating up your CPU usage, and making it overheat.

If you see this happening remove the malware as soon as possible to prevent a virus from harming your computer and to help your computer reduce fan noise.

Another problem with this whirling fan noise could be because your PC is very dusty causing a lot more heat to get trapped in your PC.

You can easily fix this problem by cleaning your PC.

Here is a guide on How to Clean Your Pc and Get Rid of Dust.

First, start by opening up your computer and using a microfiber cloth, or compressed air to get rid of all the dust. This should help keep your PC clean, and stop it from overheating. It should also reduce the fan noise.

Why Your Computer is Making a High Pitched/Whining Noise: How to Fix It

Next, your computer could be experiencing a high-pitched sound or whining noise.

If this is the issue then you don’t need to worry too much as this is most likely coming from your GPU/graphics card, and it won’t cause any damage to your PC.

This high-pitched whining noise is something called coil whine, which can happen in just about any graphics card.

The noise you are hearing is not harmful to your PC in any way and if you aren’t too annoyed by the sound your graphics card is making then there is no need to worry about it.

Here is an in-depth article that talks about Why Your GPU is Making So Much Noise and How To Fix Coil Whine.

If your GPU is making a lot of noise then I would really suggest you check out that article as it goes more in-depth on why your GPU is making noise, and it also talks about how you can fix coil whine in your graphics card.

Now, if you are still worried about coil whine in your GPU, then you should know that every GPU has a little bit of coil whine, but most of the time the coil whine coming from the GPU is very high pitched so humans can’t hear it.

If you can hear the coil whine in your GPU then you just got unlucky.

This can be fixed by, underclocking your GPU even though this will cause your graphics card to lose some performance it will get rid of that loud noise.

You can also turn on G-Sync which will sync up your GPU and help it make less noise, and finally, you can switch to water cooling as this will get rid of the noise entirely because the GPU is being cooled externally and won’t need to use fans to run air throughout the graphics card.

I highly stress that you check out that article on how to fix the noise in your GPU as it goes really in-depth on how you can stop coil whine and prevent your GPU from making all that noise. It is a very good read.

How to Fix Loud Fan in Computer

A loud fan noisy fan in your computer can become very annoying especially if it is constant.

Although there are a few ways to reduce the noise of your fan you should first run a diagnostic to figure out why your fans are making such a loud noise.

You can do this by powering off your computer and checking the case fans.

The first and most common problem could be that there is a lot of dust build-up in your fans. This can be solved by cleaning up and getting rid of the dust.

Here is a guide on How To Clean The Dust Out of Your Computer.

The dust build-up that is trapped in your fan can cause airflow issues that can make your fans become very loud and obnoxious. This is caused by two reasons.

The first being the dust on your fan blades is cutting off the smooth airflow between your blades from going in and out of your computer.

You can prevent this by cleaning off your fan blades.

The second issue could be that there is dust build-up in the bearings of your fan.

This can cause your fan to spin in an irregular motion once again affecting the airflow and causing your case fans to make a ton of noise.

Another thing that this can do is slowly degrade your fan bearings, which can shorten the lifespan of your PC case fans and affect the cooling efficiency.

If this is the problem clean your fans immediately.

The next thing you should check is if your computer is getting the proper airflow. If your computer isn’t getting the proper airflow then it can cause your fans to speed up becoming very loud.

It does this in order to keep your computer cool and prevent it from overheating.

This can easily be prevented by placing your fans in a way to allows the air to flow smoothly from one end of the case to the other.

High Pitched Noise Coming From PSU/Power Supply

If there is a noise coming from your PSU/power supply then it is most likely due to your power supplies fan. It might just be bad luck, but you should take the time to figure out exactly where the noise is coming from in your PSU.

It might just be that you got unlucky and got a bad power supply fan in this case maybe you should look into buying a new one.

However, at the same time, it could be because the fan is just dirty or dusty, this can be easily fixed by cleaning out the PSU fan by spraying compressed air down the power supply.

Another reason could also be due to coil whine in the power supply similar to a GPU coil whine is not something to worry about as it doesn’t cause damage to your computer.

You should always be safe and stress tests your power supply to make sure there are no hardware deficiencies, and that nothing is creating sparks as this is bad and means that you have a broken PSU.

If this is the problem you should get rid of that PSU immediately and look for a new one.

Conclusion

If your computer is making a lot of noise you shouldn’t panic as it is most likely not something that serious.

Although you should still take your time to diagnose where and why the noise is happening as it can cause future damage that might require immediate action.

All in all, to prevent noise from getting loud on your PC you should clean your computer regularly, and check up on all the hardware components to see if there are any failures or deficiencies, that way you can find what is making the noise right away and fix it.

I first got into building my own computer when I was around 12 or 13. The first computer I had ever built didn't work. So I kept researching to figure what I did wrong. I really enjoyed researching, learning, and building computers, so I decided to turn it into an online business, and here I am.
