We will give you the detailed solution after discussing the reason or cause. You can find a detailed solution below the reasons.

So let’s get started with our first reason that is:

1. Virus/Malware – Effects Badly On Your Laptop

Virus/Malware - Why Is My New Laptop So Slow

What is a computer worm/virus?

I think almost every person can understand what a virus or malicious software can do with any PC.

Let me tell you: It slows down the overall performance of your laptop and makes you feel irritated by doing creepy things like web browsers get stuck with multiple ads, you try to shut down your laptop but can’t do it or your important files are being deleted continuously.

When such things happen you have to understand that your machine is facing a critical situation. 


If your laptop or a PC is infected with viruses and doesn’t have an antivirus or anti-malware software then you need to install that first and check if your laptop is infected or not. You can easily do this task by running a complete anti-malware and antivirus scan.

There are many antivirus and anti-malware software that you can use. Many people use Windows Defender that is the built-in Microsoft tool that keeps you safe from any malicious threats.

But there are some people who use several paid tools that are much more powerful than Windows Defender. You can find many tools but we recommend you check Malwarebytes that is an anti-malware software and Bitdefender for antivirus. These two software has very good reviews on different sites and also on Amazon.


These types of antivirus software are regularly updated by their manufacturer. So make sure to update your security software regularly.

2. Overheating Makes Your Laptop Slow

Your next step is to check whether the heatsink is cleaned or not. In order to clean that, you need to have an electronics compressed gas duster like this. This gas duster is very useful and is specially designed for cleaning electronic components such as CPU’s, keyboard and workstations, etc.

Low Disk Space - Why Is My New Laptop So Slow

As we all know that the more disk space means a faster laptop. However, It is recommended to maintain at least 15% of disk space free on your laptop hard drive.

If you’ve not maintained your hard drive then you have to face some problems such as slow speed, lagging, and freezing of a laptop.

Maintaining at least 15% of disk space free helps you boost the performance of your laptop and eliminates freezing issues.

If you’re running out of disk space and want to eliminate this problem, you have to follow the below solution:


The solution is simple, you have to clean your laptop hard drive but unfortunately, this is not an easy job as you’re thinking. We recommend you to start removing those third-party applications that you think are just waste. Because these are the programs that are taking most of the space on your laptop hard drive.

The next step you have to do is to find those big giant videos and images files that are occupying more disk space and start removing them. Maybe you’re thinking, how would you do that?

I know many questions are coming in your mind for example,  finding all these files might take all day or you don’t know where those files are actually located. So don’t worry, We are here to answer your all questions.

4. Running Too Many Processes At The Same Time Causes Slow Speed Of A Laptop

Here’s another problem that can seriously impact your laptop speed. Consider yourself doing multiple jobs at the same time. You will feel that your energy level is slowing down.

Windows Task Manager - Why Is My New Laptop So Slow
Windows Task Manager

You cannot handle multiple tasks at the same time. That’s why many people don’t believe in multitasking. Hence, your laptop also cannot bear that. Its speed becomes slow and the system becomes unresponsive when you try to do too many tasks at the same time.

If you’re running too many programs at the same, you’d probably notice some side effects usually, the system becomes unresponsive, the system takes much time to shut down, and sometimes the mouse stuck or freezes.

But don’t worry, we have the solution to this problem. Usually, there are some apps that run in the background automatically and the bloatware that is bundled with a new laptop.


There are some apps that are installed on our laptops. These apps have no use in our life but are consuming our laptop’s resources. So, your first step should be, to disable those apps that automatically start when the system starts and optimize the startup list by using the CleanMyPC app.

Make sure that you’re using lightweight antivirus software because the software that consumes more resources of one’s laptop is this antivirus software. 

However, these are the software that performs tasks in the background. In simple words, these are the apps that are running in the background. The best example of lightweight antivirus software is MalwareBytes.

However, new laptops usually came up with a lot of unwanted software that is included by the manufacturer also known as bloatware. 

Uninstall them.

Next, you have to open the task manager by pressing Ctrl+Alt+Delete and check those apps that are running in the background and how much resources they are using. After reviewing and overviewing those apps, select those apps which you don’t need: Dispatch them.

5. Using Outdated Hardware Can Make Your Laptop Slow
