Why your Windows Laptop Is Noisy And Slow When Surfing The Internet (Explained)


Is your Windows laptop making strange noises and struggling to keep up when you’re surfing the internet?

Slow internet speeds are one possibility, but there are many other factors that could be causing your laptop to slow down and become noisy.

In this article, I explain some of the most common reasons why laptops experience these issues when browsing the web, and provide potential fixes to help get your laptop running smoothly again.


 Here are four potential possible reasons why then I explain below: malware or viruses, insufficient RAM, overheating, and outdated hardware.


Malware or viruses

Malware or viruses are harmful software programs that can infect your computer without your knowledge.

They can slow down your laptop’s performance by using up system resources like CPU, memory, and disk space.

This causes your laptop to work harder to complete tasks, leading to noise as the fan tries to cool the system down.

Malware or viruses can also cause your internet connection to slow down or behave erratically by hijacking your browser, redirecting your search results, and creating pop-ups or other unwanted ads.

This can lead to slow browsing speeds, pages taking longer to load, and other issues that can make your laptop noisy and slow when surfing the internet.

It is important to have up-to-date antivirus software installed on your computer to protect against malware and viruses.

Why your Windows Laptop Is Noisy And Slow When Surfing The Internet

Insufficient RAM.

RAM (Random Access Memory) is a type of computer memory that is used to temporarily store data that the laptop is actively using.

When surfing the internet, your laptop needs to load multiple tabs, images, and other data simultaneously, which requires a certain amount of RAM to handle the workload smoothly.

If there is insufficient RAM in your laptop, it will struggle to keep up with the demands of the internet, causing it to slow down or freeze up.

When the laptop is overworked, the system generates heat, which makes the fan run faster and louder to cool down the system.

This can lead to noise as the fan tries to cool the system down. Upgrading the RAM of your laptop can help it handle the demands of the internet better, leading to smoother performance and less noise.



Overheating is a common issue that can occur in laptops when the internal temperature rises to a level that is beyond the normal operating range.

This can lead to a number of problems, including increased noise, decreased performance, and even hardware failure if left unchecked.

One of the main reasons why a laptop may overheat is due to a malfunctioning cooling system.

The cooling system is designed to regulate the internal temperature of the laptop by dissipating heat away from the components.

If the cooling system fails to function properly, the laptop will not be able to regulate its temperature, leading to overheating.

Another cause of overheating can be a buildup of dust and debris inside the laptop.

Over time, dust and debris can accumulate inside the laptop, blocking the airflow and preventing the cooling system from functioning effectively.

This can lead to increased temperature and decreased performance.

To prevent overheating, it is important to regularly clean the laptop and ensure that the cooling system is functioning properly.

This can be done by using compressed air to blow out any dust and debris from the vents and fans, and by ensuring that the laptop is placed on a flat and stable surface that allows for proper airflow.

Additionally, using a laptop cooling pad can help to regulate temperature and prevent overheating.


Outdated hardware.

Laptops with outdated hardware may struggle to keep up with modern internet demands due to the increased complexity of websites and applications.

For example, modern websites and apps may require faster processors, more RAM, and better graphics cards to run smoothly.

If the laptop’s hardware is outdated, it may not be able to handle the demands of modern internet usage, causing it to slow down or become noisy as it tries to process data.

Upgrading the hardware of the laptop, such as adding more RAM, replacing the hard drive with an SSD, or upgrading the processor, can help improve its performance and reduce noise.

However, in some cases, upgrading the hardware may not be possible or cost-effective, particularly if the laptop is several years old.

In this case, replacing the laptop with a newer model may be necessary to ensure that it can handle modern internet demands and operate smoothly without generating excessive noise.

So, here is a chart table with 15 scenarios that may cause a noisy and slow laptop when surfing the internet, along with their potential fixes:

ScenarioPotential CausePotential Fix
1Insufficient RAMUpgrade the RAM
2Outdated hardwareUpgrade the hardware or replace the laptop
3Overheating due to blocked ventsClean the vents and ensure proper airflow
4Overheating due to a malfunctioning fanReplace the fan
5Overheating due to a malfunctioning cooling systemRepair or replace the cooling system
6Malware or virus infectionRun a malware scan and remove any detected threats
7Too many programs running in the backgroundClose unnecessary programs or upgrade the hardware
8Corrupted system filesRun a system file check and repair any corrupted files
9Browser cache and cookies buildupClear the browser cache and cookies
10Browser extensions and add-onsDisable or remove unnecessary extensions and add-ons
11Slow internet connectionUpgrade the internet connection or switch to a different provider
12DNS server issuesChange the DNS server settings or use a different DNS server
13Browser compatibility issuesUse a different browser or update the current browser
14Power settings affecting performanceAdjust the power settings for better performance
15Hard drive issuesRun a disk check and repair any errors or replace the hard drive if necessary

It’s important to note that some of these scenarios may overlap, and it may take some troubleshooting to determine the root cause of the issue.


In conclusion, a noisy and slow Windows laptop when surfing the internet can be a frustrating experience, but there are many potential causes and solutions.

From hardware upgrades to software fixes, it’s important to identify the root cause of the issue and take appropriate action.

By following the suggestions in this article, you can help improve your laptop’s performance and enjoy a smoother browsing experience.

Remember to regularly clean your laptop’s vents and keep your software up to date to help prevent future issues.
