16 Reasons why Computer so slow & How to Speed Up Computer

Why is my computer so slow? my computer is lagging!” This is a complication, that all the users have already experienced.

Why is your computer taking so much of its time? Rest assured, there are at least as many solutions to reduce the slowness of your PC as there are problems related to these slowdowns.

Your device is slow to start or makes you wait too long when you are on the internet?

We help you find the reasons for these slowness and how to increase the speed of your PC.(why is my computer so slow?)

what you need to know first

A PC is slow because it has undergone changes (intentional or not) hardware or software that made it become so.

The most popular misconceptions that a PC is lagging is due to the following facts:

  • Antivirus and cleaning software, to stand out from the competition, look for the smallest problems to offer a more complete product than those already in existence. While sometimes these problems are not really . On the contrary, constantly looking in the background for trivial problems can actually slow down the machine .
  • Popular beliefs that the number of items appearing on the screen (like icons on the desktop) means that the computer has to work with it and cannot handle everything at once after a certain threshold.
  • Popular beliefs that a slow computer is bound to be a sign of infection.

Why is my computer so slow?

Your computer is slow for the following reasons which I will then go into one by one :

  1. Of unwanted extensions load advertising content when surfing the Internet
  2. Several people are connected to the same access point
  3. You have a bad WiFi signal
  4. The problem is on the server side (site)
  5. One or more programs are very memory intensive (poorly optimized)
  6. You have too many (active) programs
  7. Your PC is slow because it’s dusty
  8. Your data is fragmented
  9. Your software is not up to date
  10. The case of Rogues software
  11. Problems performance
  12. And finally, malware

16 points most likely to be related to speed problems your computer in detail :

1. Unwanted extensions load advertising content massively when surfing the internet

computer slow

these are extensions that dynamically modify the content of web pages. Typically, you think of installing an extension allowing to “download videos in mp3” while at the same time the search results are found to be modified on the fly to include advertisements. 

These same advertisements which must be loaded with obvious consequences on the speed of connection.

How to fix the problem:

Observe installed extensions and remove unnecessary or unwanted ones. Or directly reset the browser. You can type “chrome: // addons” in the URL bar in Chrome, or “about: addons” in Firefox to see the extensions.

2. Several people connected to the same access point

why is my computer so slow

Why is my computer so slow? The different devices connected to an Internet access point share the bandwidth . If a local network user downloads a large file, it takes up a lot of the bandwidth and your connection slows down.

How to fix the problem:

Difficult to solve except to dialogue with the people concerned to establish an equitable sharing. There is also a software called inSSIDer to change the Wi-Fi channel when it is saturated in your neighborhood.

3. Bad Wi-Fi signal

why is my computer so slow

It’s not just the distance that comes into play, but also the obstacles blocking the signal. In particular what is at the base of liquid (radiators) or which generates waves (microwaves).

How to fix the problem:

Try to place the modem in the center of the house, away from obstacles blocking the signal. And try to stay as close as possible to the modem when connecting to it via Wi-Fi.

4. The problem is on the server side

why is my computer so slow

A slow site doesn’t necessarily mean your connection is slow. Sometimes it is remote server that is overloaded and struggling to respond. To find out if the problem is remote just try other sites to see if the loading is faster or not.

How to fix the problem:

Wait until the server is less loaded when connecting later.

5. Gourmet programs in general

Any program (benevolent or not) can use a lot of resources (memory or processor). Just like the bandwidth shared between computers on the local network, memory and processor resources are also shared between programs . And if your RAM memory is full due to a too hungry program, the computer will be slowed down.

How to fix the problem:

You can open the task manager (CTRL + SHIFT + ESC) and directly observe the Performance tab which indicates the level of use of your memory (but also of your processor and your disk)

If the memory is almost full, you can identify the over-hungry process via the Processes tab .

6. Too many programs at startup

why is my computer so slow

Programs launched at startup directly affect the startup speed of Windows. The difference can be of the order of several minutes. 

Moreover, there are some cases that are more difficult to spot which also affect startup, but rather appear as software or hardware bugs.

How to fix the problem:

To see the programs launched when your computer starts up, you can launch the Task Manager (by simultaneously pressing (CTRL + SHIFT + ESC) then go to the “Startup” tab.

7. Your PC is slow because it’s dusty

The dust gets into your computer. If you don’t have the inside of your machine cleaned regularly, dust will clog the components and prevent them from functioning properly. If there is too much space, the computer will heat up and the damage can be serious .

Dust in the fans blocks the air flows vital to cooling the computer. If the system overheats, it is automatically inhibits its performance to generate less heat.

How to fix the problem:

If the PC can be taken apart, you can do it without expert help. You can blow (or rather vacuum) the dust inside the computer. Be careful not to damage the components at the risk of having a PC that no longer works as a bonus.

8. Fragmented data

Fragmented data, that is, data scattered all over the disk, takes additional time to process. Recent versions of Windows automatically defragment disks .

How to fix the problem:

This problem is usually automatically fixed, otherwise here are some more details on how to do it manually .

9. Drivers that are not up to date

up to date computer

Although this is more of the exception, problems with the drivers can cause errors and unexpected slowness. 

These errors are not necessarily linked to updates, but may be due to software conflicts . To detect them, you can open device manager (type “devmgmt.msc” in search bar of the start menu).

How to fix the problem:

If you see small warning icons next to a device, it means that it is not functioning correctly. It is advisable to stop or update it.

10. Rogues software

The Rogues software are fake programs that make you believe that your computer is full of viruses and other problems, they offer you to correct. 

When in fact it is not, and it is this software itself that takes resources to look for non-existent problems.

How to fix the problem:

Become aware of the scams that target us every day and keep only the programs recognized for their usefulness.

11. Performance problem

If there are no other solutions, it may simply be that the computer is lacking in performance (too little RAM memory, too little processor power, etc.). And actually this is the most common problem!

How to fix the problem:

For this it is possible to change a component such as the graphics card or the RAM memory. Otherwise it’s good to change your computer, and frankly it’s good to renew it every 5 to 10 years if you feel that it is getting old at one point or another.

12. Malware

Malware can slip into your computer. When only one malware is present, it is sometimes difficult to detect its activity. 

On the other hand, when several have infested your computer, the difference is greatly felt. Your computer can then be completely blocked by these software.

This is a point that we have seen as a preconceived idea. I said that the trail of the “virus” is often the first to be highlighted, but there are many others as we have just seen. 

However, sometimes malware slows down the computer . But let’s be more specific. We have seen, for example, that the programs that start when the computer starts up have an impact on the startup speed. 

This is especially true of malicious programs, which are often launched when the computer starts up .

Others may use the network heavily (to send data remotely, or to receive commands) which can potentially slow down your connection.

How to fix the problem:

Protecting your computer relies on many points that must be met. The ideal is to start with the classic antivirus scan. 

Then it is interesting to make sure (using third-party programs or manually) that the PC is healthy and that the antivirus has not forgotten something. And finally, awareness works wonderfully, knowing the attacks and therefore the defenses will always be better than any antivirus in the world .

13. Your computer’s memory is full

Computers are equipped with hard disks to allow data storage. However, the storage capacity of these disks is not unlimited and when they are full, one can observe strong slowdowns. 

To limit saturation, you can opt for an external hard drive , useful if you store movies, photos or music.

Another solution: uninstall unnecessary software that takes up space for nothing. If there is some software on your computer but you are not using it, there is no point in keeping it. Uninstall them to free up space on the hard drive.

14. Your computer is running low on memory (RAM)

To use the various programs, a computer uses random access memory (RAM). However, your computer may run out of this memory and you may notice the appearance of slowness. 

The solution to this problem is to add more memory through computer components. It is therefore necessary to dismantle the computer. 

In order to avoid unpleasant surprises, we advise you to call in a specialized professional who will take care of the dismantling and the addition of memory in complete safety.

15. Your computer’s hard drive is fragmented

Drive fragmentation means that your data is scattered in different places on your hard drive. 

This scattering can ultimately cause a slowdown in the use of your software. Defragmenting your hard drive once a month corrects this problem.

16. Your computer starts too many programs on startup

Some programs start automatically when your computer starts up. When there are few of them, it does not affect the speed of the computer too much. But in too large a quantity, your PC will hardly support and can take up to several minutes before launching. 

Be careful, when downloading software, to uncheck “run on startup” type boxes.

How can I fix a slow computer or How to speed up computer ?

how to speed up computer

1.Computer too slow: solutions

Year after year, computers slow down. Two years after purchase, Windows starts up significantly slower. 

When to worry When the computer takes four or five minutes to start , when it blocks three seconds to switch from one software to another. Sadly too frequent case. 

Some users experience much worse: a computer can take fifteen minutes to start, two minutes each time you open a program, ten seconds each click. Slowness as abnormal as they are intolerable.

The first reaction would be to buy a new PC. We must resist it. Especially if the computer is less than four years old . 

In this case, you have to take your courage in both hands. A good cleaning takes two hours. Start by removing unnecessary software. Free up some space on the hard drive. Eliminate viruses.

After that, if the computer remains slow, a deep cleaning is required (method 2). And maybe even a reset (method 3), which will restore the PC to its prime, but which requires a day of effort. 

Apply these solutions in crescendo. If the first method is not satisfactory, go to the second. The third is reserved for the most problematic cases. 

2.Uninstall unnecessary software, make updates

•  Uninstall unnecessary software

The first cause of slowdown is the installation of too much software. Each new program slows down the computer. Conversely, each software removed speeds up the computer. So uninstall unnecessary software. 

As a general rule, you have to remove a lot of programs to notice a marked acceleration. But sometimes removing big software is enough.

 only delete the programs that you know. Never kill a program you don’t know how to use.

Here are the steps to follow. Click the Start menu , then click Control Panel .
Have Windows XP, click Add or Remove Programs .
With Windows Vista, click Programs and Features .
With Windows Seven, click Uninstall a program . 

The other common cause of slowdowns is memory saturation. To function properly, a computer needs a small amount of blank space on the hard drive. It occasionally uses it to store information. Without this “virtual” memory, it occasionally experiences severe slowdowns.

How do I verify that the computer has enough virtual memory? Click on the Start  menu  and then on  Computer  (or  My Computer ). A window is displayed: click on  (C 🙂  with the right button of your mouse. Left-click on  Properties . 

In the circle that appears, blue corresponds to the space used, purple to If you have less than 2 GB of free space, cleaning is required . Delete some large documents. 

For example, files of images, music, or videos. Click on it, then press the Delete key  , and validate. At the end of the cleaning, empty your trash. Right-click on it, then press  Empty Trash .

The older a computer, the more its hard drive is fragmented into thousands of niches. This fragmentation slows down the computer. 

Since 2008, Windows automatically cleans up the hard drive. Unfortunately, on some computers this maneuver, called defragmentation, must be started manually.

Once started,  the process takes a few hours. Trigger it before you go to bed. Click the Start menu  , then  All Programs , then  Accessories , and finally System  Tools . Click Disk Defragmenter , then  click  Defragment .

Antivirus is the last cause of slowdowns that is easy to fix. When changing antivirus, some users forget to uninstall the old one, which slows down the computer a lot.

Check that only one antivirus is running on your computer. If necessary, uninstall the old one. 
Other users make the opposite mistake. 

They neglect their antivirus, paving the way for malware. These can dramatically slow down the computer: it is common. If you don’t have an antivirus, install one ( read   Free or Paid Antivirus? The match ). Run a full computer “scan” to remove viruses. 

If you have an antivirus, but neglect updates, the problem is the same. Your antivirus is out of date. Malware may have crept onto your PC. Uninstall your antivirus and install a new one. Then scan your computer.

3.Method 2: deep cleaning

All these manipulations may not be enough, because an aging computer suffers from other problems, more complex to solve. The “registry” is getting dirty. 

RAM is saturated with software. This specific memory, ultra-fast but tiny, is essential for the proper functioning of the computer. 

In addition, spyware can grab the attention of the computer and slow it down. Windows startup can be unnecessarily heavy.

Cleaning the registry, organizing the RAM, cleaning up the startup, eliminating spyware are four complex operations. 

We use an assistant to achieve this. Glary Utilities software is the most comprehensive, but it is reserved for computer aces. A beginner would risk making mistakes that could lead to computer paralysis.

The average user will preferably acquire simple software. We recommend TuneUp . This cleaning program takes the user by the hand, avoiding nonsense with serious consequences. TuneUp is free for two weeks. Sufficient time to clean the computer. After the fortnight, it costs 40 €.

4.Method 3: reset

Did the two previous steps fail? Is the computer still very slow? There is one last solution: reset everything . Experts appreciate this radical method. 

We get a computer like new, as fast as the first day. Allow a day’s work. To be successful, good computer skills are necessary because this method is risky. 

After the reset, everything disappears from the computer. The software you have installed vanishes. 

The information you have saved disappears: photos, texts, videos. It is therefore essential to safeguard this information. This will allow these documents to be returned to their place after the reset.

Backing up is a long and complex process. Take a complete inventory of the information stored on your computer. Then copy them out of the computer. For example on an external hard drive or on a large USB key .

List the programs you have installed on the computer since it was purchased. Check that you have the installation CDs for these software, and the precious “installation keys” without which installation is impossible. If the backup is not complete, expect disaster. If the backup is conscientious, everything will be fine.

In computer jargon, a reset is called a full reinstallation.. Two methods are available to you. If the computer package contains the installation discs, that’s easy. Slide disc # 1 into the CD drive, turn off the computer, and turn it on again. 

The re-installation begins automatically. Follow the instructions, opt for a total re-installation with formatting the hard drive. This corresponds to a complete erasure.

What if the computer manufacturer does not provide the installation discs? It’s more complicated. Consult the instructions for your computer under the heading “Complete re-installation”. 

You may need to purchase a re-writable DVD to burn a boot-able disc. Follow the manufacturer’s directions exactly.

Once the re-installation is complete, Windows may ask you for “installation drivers“: graphics card, sound card, etc. Without them, the computer refuses to play sounds, the screen appears in coarse resolution, etc. 

These drivers are probably located on another CD provided by the computer manufacturer. Insert it into the optical drive of the PC and tell Windows where the drivers are. 

To finalize the re-installation of the computer, it remains to replace the missing software. Remember that each new program slows down the computer. Install only essential software . 

Finally copy the documents saved on the computer. And if you still have the patience, take the opportunity to classify them.
