Desktop computer or laptop running slow? What are the reasons behind it and how to fix it?
When we buy a new computer it's as fast as a lightning bolt. However, as time goes by, computers tend to become slower and slower. There are many reasons why a computer can become slower, among which the most common are:
The solutions listed below work on any laptop (Dell, Asus, Acer, HP, Msi, MacBook, iMac, Mac) on any operating system (Windows, Mac OS, and Ubuntu). They will help you speed up your computer, and improve its performance. All you need to do is to follow them to the detail.

While you are browsing the Internet, you might accidentally (or deliberately) install extensions. They usually change your homepage and offer you various games, programs, music, and other content you are not interested in. But, they can also slow down your browser and computer, because the extensions will require more of your computer's resources. To resolve computer speed issues while browsing the net, the best solution is to remove the extensions.

Sometimes, the answer to "why my computer is running slow and freezes?" is an unresponsive piece of software running in the background, and draining the computer's resources is the reason. Restarting can help if your computer gets slow, because it will close software which are running in the background (and using your computer's resources) even though they're not needed anymore, or if a software has become unresponsive. Also, restarting the computer should help if you haven't shut your computer down for some time and it performs tasks slowly.
Another reason for the computer running slow issue can be the presence of virus(es) and other types of malicious software. Viruses can make your computer very slow, as they are designed to harm you in every possible way (e.g. they can prevent you from browsing the net with the speed you pay for, to play games, videos, etc.). The solution is to remove them, however, there are some viruses which may bypass your antivirus scanner, which is why it's imperative that you choose a trustworthy solution. Removing the virus is just one small step. What you should really focus on reducing the risk of viruses entering your computer again, by following the tips below:

A good communication between your computer's hardware components and the operating system is made possible thanks to the drivers. Installation and regular update of the drivers is a must, in order to fix a slow computer, and to be able to use your computer's full potential.
You can update drivers following one of the approaches below:
Note: For more information on installing and updating drivers, the how to download drivers and how to update drivers guides can assist you.
Asking a tech-savvy friend for assistance with speeding up your computer is a good way to fix this issue, as maybe it would take your friend 5 minutes to isolate the issues, as opposed to the 1+ hours that could take you, if you do research.
Every program you install (or uninstall) in your computer, modifies the registry. The registry is a vast library of system settings - settings that can sometimes lead to blue screens and other instabilities. Even when programs are uninstalled, their registry settings can stay behind.
The settings are useless to the daily operation of your PC, but they can cause conflicts and errors. Your computer continues scanning these error-ridden registry entries, thus slowing everything down. As a result of this, your computer crashes.
Cleaning the registry manually is not an easy task. Luckily, software which can clean the registry instead of you and fix a slow computer do exist.
Ccleaner - for Windows users or Ccleaner for Mac users is one of the best for this task. Other software include Advanced SystemCare (MacBooster - Mac OS), Wise Cleaner (Windows only) etc.
All you have to do is to install one of them, follow the user-friendly instructions and leave the rest to them. Make sure to scan your computer regularly (at least once per week).
Every activity you do on your computer leaves residues. The residues such as browsing history, temporary files, etc. accumulate and the computer becomes slower. Even though they are made to make operations faster, if they become corrupt, they turn out to do quite the opposite. In order for you to improve the computer's speed and performance, you need to do a system cleanup.
Windows offers a utility known as Disk Cleanup. To run this tool, follow the steps below:
Under Files to delete, select the file types to get rid of (by ticking the checkboxes next to them) and click on OK.
*Repeat this for each drive separately ( "C:" "D:" "E:" and etc.).
Everything we do on your computers leaves residues known as temp files. A small amount of temp files won't do harm. However, a greater amount of temp files can slow down the computer.
Cleaning temp files manually is not an easy task, as it's hard to tell what can be deleted, and what not. This is why it's best to download and install dedicated software like CCleaner, Advanced Systemcare (which are one of the best for the task, according to users), and scan and clean your computer on a weekly basis.
One of the reasons why computer is slow may be the amount of fragmented files. When you install and uninstall applications or when you move files, you leave behind leftovers known as fragmented files. Fragmented files can slow your computer down if they aren't taken care of.
Windows has an easy-to-use built-in utility that defragments your hard drive, called Disk Defragmenter.
If you use a hard disk drive, to run the utility, follow the steps below:
Note: If you are using SSD (Solid-state Drive) DO NOT DEFRAGMENT IT, because if you do, you might damage it. SSDs store data in a sequential order (as opposed to random order).
Also, don't defragment the System Reserved partition, because it is meant only for system files, which are important for the computer.
One of the reasons why computer is slow is the number of programs running in the background. Some programs installed in your computer run in the background without your knowledge, and they occupy significant amount of the computer's RAM memory, which is one of the main reasons why your computer is running slowly. By closing some programs you don't need at the moment, you will free up more of the computer's RAM memory and increase your computer's speed.

This is a must-do. Remember: an update a day, keeps the repair guy and hackers away. Also, with every update, improvements are introduced, as well as new features. To update Windows to the latest version, follow the steps below:

Animated pointers and high-resolution images may look nice, but they can also slow down your computer. The animations and images occupy the computer's RAM every time you start your PC and as a result there is less processing power available for other more important tasks.
So, if your desktop computer or laptop is running really slow, try to avoid using animated pointers, animated backgrounds and other third-party widgets so that you have more available memory for other more important tasks.
Maybe it's not your computer which is slow, but your Internet connection. In this case, it's either your Internet connection itself, or the router itself, or the computer's distance from it.
To improve the Internet connection, you may do the following:

The built-in Aero technologies give Windows a three-dimensional look, with semi-transparent window frames. Microsoft added Aero with Windows Vista, and kept it through Windows 7. It's on by default in both of those Windows versions-except for the Windows 7 Starter Edition, which lacks Aero entirely. However, this three-dimensional look can slow your computer down, especially the older computers.
If you wonder how to fix a slow laptop or computer, running on Windows 7, consider disabling Windows Aero. In order to disable Windows Aero right-click the anywhere on your desktop -> Personalize -> find the Windows 7 Basic theme on the list and select it. The windows aero will be automatically disabled.
If your desktop computer or laptop is running slow and you've been using it for a long time (e.g. over 2 years), consider upgrading its hardware components, such as the CPU (Processor), RAM, Hard drive/SSD, etc, provided that your computer will support the new ones (feel free to consult the manufacturer's website for more information on the specifications).
If you are using weak or obsolete hardware components, it will be almost impossible to browse the net with a good speed, watch a movie and install new programs, etc., because developers create new websites and programs which consume more memory and which can work properly only on computers that have the latest, or not-too-old hardware components installed.
Your computer needs free space so that the operating system can function properly, and execute the necessary tasks. Maybe your computer is slow due to a lack of free storage space. So if you don't have enough space in the hard drive, and your desktop computer or laptop is running really slow, consider removing the files you don't need, in order to free up hard drive space. Files you can remove, aside from temp and cache files are:
You can purchase external hard drive, too, and store data there, too, while removing it from the computer.
Check out the running out of disk space / no space left solutions to learn how to free up hard drive space.
Starting up a computer is like one climbing a mountain and setting up a picnic table near the top. If too many programs start when operating system starts (e.g. Skype, WhatsApp, etc.), they can slow your computer down. It would be like the man climbing a mountain took more and heavier bags, which makes it difficult for them to climb To fix a slow laptop or desktop computer, you should start with disabling startup programs you don't need opened automatically when you turn on your computer.
For more detailed information on how to disable startup programs, check out the how to disable startup programs guide.
If your desktop computer or laptop started running slow after you have installed new programs or games, it is possible that one of them is slowing down your computer. Uninstalling the recently installed programs and installing them one by one, to identify the culprit, should fix the problem.

Too many background system processes can slow down your computer.
If you wonder how to speed up a slow laptop or desktop computer, close any background programs you don't need. Remove unnecessary Windows desktop gadgets (Windows 7), and all those programs that hide themselves in the system tray. Disable or uninstall any application running in your system tray that you don't actually need.
