The proper operation of a computer is dependent on a variety of hardware components. Over time, these components can become faulty. If you’re a computer owner, you may encounter a few problems that can make your computer run slowly. 

 If the computer suddenly produces noise and crashes while working, your computer needs maintenance or repair. This article will help to explain why your computer is lagging or slow and what you can do about it.

Reasons for computers slow down.

Here are the reasons that can cause your computer to lag:

  1. Too many open web pages

If there are too many web pages open at once, it starts lagging. If you have more than twenty tabs open, your computer will begin to lag as it tries to keep track of all those available web pages. To avoid this, close some unnecessary tabs before starting another task on your computer. 

  1. Excessive heat production

When the computer is running many applications, it’s easy to overheat, which can cause your system to slow down. This is especially true if you’re using an older computer or a laptop that doesn’t have an adequate cooling system.

To avoid this problem:

  • Close all unnecessary apps and windows, including web browsers and chat clients (like Skype)
  • Don’t put your laptop on your lap—you’ll only make things worse!
  1. There are some HHD or SSD problems.

HDDs are data storage devices with rapidly rotating disks coated with magnetic material for storing and retrieving digital information. An SSD, also called an “enclosure,” is a computer component containing flash memory that stores persistent data.

A hard disk drive can be damaged by dropping or banging it against something. While SSDs are more easily damaged by extreme heat or cold. They’re also more prone to damage from static electricity than HDDs.

  1. Old hardware with new software

A computer’s performance depends on its hardware, which includes the processor speed, RAM, hard disk space, graphics chip and video card. 

If you upgrade only one part of your PC but keep the others intact, then it will be unable to work properly because not all features are updated at once. To improve the performance of your computer, you should also update your hardware. 

  1. Limited power supply

If your computer doesn’t charge properly, the first thing that you should do is check the charger and see if it’s working properly. 

The next possible cause is the limited power supply that dont support the system. Therefore, due to the low power supply system crashed. 

  1. Too little memory (RAM)

Your computer needs a certain amount of RAM to run properly. This is your computer’s memory to store information that you currently use and will continue to use. It will be very slow if your system tries to read from or write to this temporary storage space.

  1. A dirty or damaged charging port or battery connector

The charging port or battery connector may be dirty or damaged if your computer is not charging properly. These can easily get clogged up with dust and dirt over time

If either of these is damaged, they might be unable to transfer electricity properly between themselves and their respective components. This can cause unpredictable behavior, such as irregularly-charging batteries or a device that won’t turn on due to corrupted software files in its RAM chips.

It can be frustrating when you turn on your computer and it takes forever to load. But don’t worry! This isn’t usually due to a problem with Windows or any other software. A simple battery issue often causes it. 


It is important to remember that it is most likely an issue with your device if you are experiencing computer lagging or slowdowns. Many different things can cause these issues, but a few are more common than others. If you have tried all the steps above and still cannot fix the problem, it might be time to call in some professional help!

What main issues can cause your computer to lag or slow down?

Your computer lags or slows down for a variety of reasons, but some of the most common causes are:

  • Malware – malware is a term used to describe a wide range of malicious software that can infect your computer without your knowledge. This includes viruses. 
  • Overheating – if your computer overheats, this will result in sluggish performance and crashes because the processor isn’t able to cool itself properly then go to computer and cell phone repair stores. If you keep finding that your computer randomly shuts off due to overheating issues, consider upgrading or replacing the internal fans inside it!
