Why is my laptop so slow? This question bothers a large number of users and they all want to find useful ways to speed up the laptop effectively.

It’s a common phenomenon that your laptop slows down over time. The laptop is slow after working continuously for a very long time or when the laptop has been used for years. However, there must be some problems if you find the laptop running slow suddenly or a brand new laptop becomes slow (there are many users saying my new laptop is slow).

In addition to why is my laptop so slow, you may also ask: how to make laptop faster, how to make computer faster, questions like that. The following content will explain the main reasons why my laptop is so slow and give some useful tips on how to speed up laptop.

A slow laptop or computer can make even the simplest tasks feel like a real hassle; this is very annoying. In general, more and more data, files, and programs will be accumulating as a result of regular laptop use. This will have a great impact on the responding time for sure; resulting in a lower work efficiency and productivity. If this is the case, it’s very easy to make your laptop faster by deleting the useless and infrequently used files/apps.

This page discusses about: the common reasons for laptop running slow, how to speed up laptop or how to speed up computer Windows 7, Windows 8, and Windows 10.

Note: The steps of solutions to laptop running slow (including HP laptop running slow) in the following content are finished on Windows 10. As for how to fix Windows 7 running slow or Windows 8 running slow, there are only a few differences in the methods and steps.

Reason 1: Too Many Programs Are Running

Situation 1: too many startup programs.

One of the most common causes of a slow laptop (or computer) is too many startup programs. Most of the time, when you install a new program on the laptop, you’ll be asked to give permission for allowing it to start while the laptop is booting up. This will obviously increase the boot time and slow down your computer.

Situation 2: too many programs running in the background.

You have much more programs running on your laptop than you can image; you don’t even know which programs are running since they won’t ask you for permission and are running in the background. Besides, some programs still runs in the background after you closed them on laptop.

Situation 3: too many programs are running simultaneously.

Users are accustomed to doing a lot of things at once while using the laptop; this can help to save time and improve work efficiency. However, if there’re too many programs, applications, and files opening at the same time on laptop, it will be slow down.

These programs will eat up your processing power so as to slow down your laptop. In this case, closing unnecessary programs completely or restarting your laptop is the direct solution to speed up. Besides, you can also add RAM (Random Access Memory), which decides the computer’s ability to run multiple programs at the same time.

Reason 3: Your Laptop Is Infected by Virus

If you find ads are popping up or programs are crashing suddenly, you may suspect that there’s virus on your laptop. Virus, spyware, and malware can slow down your laptop and even ruin your data; they’re very dangerous. You should get your laptop away from virus by keeping these things in mind:

  • Don’t open emails from unknown senders.
  • Don’t click links from untrusted sites.
  • Don’t download files casually from the internet.

Besides, you should run a virus scan in order to detect all the virus and malware on your device and then choose to clear them completely.

Fix: Use Windows Security

You can use the built-in Windows Security to scan for virus.

  1. Press Windows + S.
  2. Type security.
  3. Select Security at a glance.
  4. Choose Virus & threat protection.
  5. Click Quick scan and wait.
  6. Follow the instructions to complete rest options.

Quick scan

Besides, you can acquire a powerful and reliable antivirus program to help you kill virus and protect your system in the future. Please always keep your antivirus program up-to-date in order to protect your laptop against the latest viruses.

Reason 4: Browser Issues

Situation 1: there are too many tabs opening in your browser or there are too many browsers running on your laptop. Each time you open a new browser tab, it will be saved in RAM; so your laptop may become very slow if you have little RAM left but too many tabs opening in the browser.

Situation 2: the browser you are using has too many add-ons. Users’ web experience could be greatly improved by browser add-ons (also called extensions). But too many add-ons can also eat up too much of your processing power so as to slow down your laptop.

Fix 1: Open Fewer Tabs at Once

Obviously, you should go to close some tabs (open fewer pages) in the browser at once.

  • Close a tab by clicking on the X button on it.
  • You can also press Ctrl + F4 to close the active tab.

This is an effective solution to Windows 10 very slow and unresponsive if it’s caused by browser eating up too much processing power.

More directly, you can add more RAM to your slow laptop to make it run faster ever than before.

Fix 2: Disable or Remove the Extensions

In this part, I’ll take removing Chrome extensions as an example.

  1. Click on the three dots icon in the upper right corner of an opening Chrome browser.
  2. Navigate to the More tools option in the drop-down menu.
  3. Select Extensions from the submenu.
  4. Browse all the add-ons/extensions you have and decide which ones are not necessary.
  5. Click on the Remove button under each extension.
  6. Click Remove again in the pop-up confirmation dialog.

To disable an extension, you should finish step 1 ~ 5 and then toggle the switch to off.

Remove extensions
