Why is my computer so slow?

A lot of people have been having trouble with their computers slowing down. If you have been having a problem, or your computer has been acting slowly for some time, it may be due to one of the following:

poor hard drive, corrupted registry, malware, a virus, or outdated software.

Irrespective of what the issue may be, I’ve researched and found 15 of the most common reasons why a computer may run slowly and also added how to fix it.

15 Reasons Why Your Computer Runs Slowly

Why is my computer so slow

Restarting Is Required.

When was the last time your PC was restarted? If your computer is running slowly, it may be time to restart it, especially if it has been a while since you last did so.

This is due to the fact that several processes operate in the background while you use your PC. When too many of these background processes are left running, they consume a significant amount of your computer’s resources, slowing it down over time.

  • How to fit it: Restart your computer after closing all apps and folders. Also, whenever a software installation or upgrade prompts you to restart now or later, always opt to restart your computer right away.

Too many open programs or tabs in the browser

How many programs do you have open at any given time? In your browser, how many tabs are open?

In your Random Access Memory, each open tab and piece of software takes up a certain amount of space (RAM). If you have too many of them open at the same time, your computer’s memory and processing capacity will be reduced, making it difficult to switch from one program to the next or from one tab to the next.

Yes, a PC is designed to allow you to run multiple processes at once, but that does not mean you should always do so.

  • How to fix it: In your browser, just open the tabs you need at the time. Simply bookmark pages and shut the tab if you want to store them for future reference. You can organize your bookmarks into folders for easier access to bookmarked pages, such as for work, recipes, reading, and so on.

Only run the apps you need right now, and then shut them down when you’re done.

Processing power is being sucked by rogue programs.

There may be programs operating in the background that are consuming a significant amount of RAM memory and processing power without your notice. This could be software that encountered an error but did not entirely shut down or software that is trapped in a background loop.

How to fix it:

  • For Windows users: To launch the Task Manager, press (Ctrl+Alt+Del).
  • For Macbook use: To launch the Active Monitor, press (Cmd+Space, type ‘into highlight bar’).

Then select the CPU tab. You’ll be able to observe which applications are running and how much processing power they’re using this way. Stop tasks that are active but not frequently used to free up processing power in your RAM.

Maxed-Out Hard Drive/Memory

A computer’s processing performance can be reduced by up to 50% if the hard disk is at least 85% full.

This is because the virtual memory needed for saving temporary files that allow programs to execute smoothly is currently in short supply. The majority of the drive space is taken up by software, application updates, downloads, files from uninstalled software, and temporary files.

When it comes to RAM, the main culprits are software that requires a lot of memory to execute. Graphic design software, such as Photoshop, and other industry-specific apps are examples.

How to fit it: Determine how much free space you have on your hard drive.

  • For Windows users, go to My Computer, then right-click local disk C and select Properties from the drop-down menu.
  • For Mac users, select About This Mac from the Apple menu.

Note: At least 20% of your total disk space should be free, and if it isn’t, there are a few things you can do to improve it:

  • Empty your trash.
  • Use the disk cleanup program to remove any temporary files and other unwanted files from your computer.
  • You can also get free apps that have been verified to erase and clean up any unneeded files on your PC.
  • Find a cloud storage provider and use it to store some of your large and important files on your PC.

Note: You will need to install additional RAM hardware to fulfill your needs if your RAM is maxed out.

Unwanted Software Updates

It’s critical to keep your installed applications up to date in order to keep them functioning smoothly and safely.

Nonetheless, some of this software comes with pre-installed automatic updates that continue to operate in the background unnecessarily, consuming important hard drive space and slowing down your computer.

  • How to fix it: Find a preventive computer maintenance solution that works for you. Essentially, when the system is not in use, this solution should be in charge of applying all required updates and patches to all of your software.

When you turn on your computer, there are far too many apps that open automatically.

Almost every piece of software you install on your computer will come with a prompt asking for permission to run when your computer boots up, a feature known as “startup programs.” This is how many of your computer’s apps and programs start automatically loading and running in the background as soon as you switch them on. This congestion is the cause of your computer’s slowness right from the start.

How to fix it: Always be cautious when downloading programs, and uncheck the option allowing them to run when your computer begins if it is not required. You can also withdraw existing app or software permissions by using the following methods:

  • For Windows users: Select the Task Manager by pressing CTRL+ALT+Delete. To disable an application, go to the Start Up tab, right-click on it, and select Disable.
  • For Macintosh users: Uncheck the superfluous programs in either Login Items or Applications.

Viruses or Ineffective Anti-Virus Software

If everything else on your computer is in working condition, the existence of a virus or ineffective antivirus software that is unable to detect and prevent viruses from infecting your computer should be considered the cause of your computer’s slowness.

Viruses can appear in a variety of ways, from random pop-ups to unauthorized file encryption. There are also infections that run in the background, consuming your resources without your knowledge.

  • How to fix it: As a cybersecurity tool, download trusted and well-known antivirus software. Use it to perform a malware scan on your PC on a regular basis to check for viruses or malware.

Operating in Low Power Mode

This may cause your Windows laptop to slow down if it is in low power mode (power saver mode). Running your laptop in low power mode reduces its efficiency, slowing it down.

  • How to fix it: Select Hardware and Sound, then Power Options, and then Create a Power Plan from the Control Panel menu.

High Performance, Power Saver, and Balanced should be the three options offered.

Select High Performance or Balanced as your new power plan and activate it.

There are too many browser add-ons.

Do you really need all of your browser extensions? And do your browser addons do what they’re supposed to do? Too many ineffective browser extensions may be slowing your computer down rather than improving your browsing experience.

  • How to fix it: Find all of your browser’s add-ons. Those that are required and efficient should be kept, while those that aren’t should be disabled.

The PC is being used for cryptocurrency mining.

It’s quite likely that your computer will be utilized to mine cryptocurrencies without your awareness or consent.

This usually happens when you download an application that has spyware installed in the background that allows you to mine cryptocurrency on your computer.

Furthermore, certain websites have code that mines cryptocurrency on PCs while the site is active.

  • How to fix it: Shut down your browser while it’s not in use to avoid crypto mining on your computer.

You may also check if your PC is being used for crypto mining by using Task Manager or Activity Monitor to look for unusual programs or tasks that are sucking up processing power even when not in use. You should terminate the program or job once you’ve identified it.

The OS’s visuals are very high.

If your RAM is not large enough to support the effects, activating visual effects on your computer may cause it to perform slower than usual.

How to fix it:

  • For Windows users: Depending on your Windows version, go to Performance Settings or Advanced System Settings, click on Adjust visual effects, and then select Adjust for optimal performance.
  • For Macintosh users: uncheck the Animate Opening Application option in System Preferences.

Internal Dust on the Computer

You could be suffering from a slow computer simply because you neglected to follow the fundamentals of good ventilation. Dust in your CPU might hinder your processors from cooling properly, allowing excessive heat to build up within your computer. As a result, the pace at which your computer operates may be affected.

  • How to fix it: To keep your computer’s air vents clear, dust them off every now and then. Also, have an IT specialist clean the interior of your computer once in a while.

Outdated Drivers

You’ll need drivers to interface with the hardware devices attached to your computer. If you have outdated drivers, your computer’s connectivity will most likely be defective, and it will take longer than it should to get the linked hardware devices to work properly.

  • How to fix it: Find the most updated drivers suitable for your computer hardware on the internet, download and install them, or use driver updating software to find and install the drivers automatically.

It’s possible that your computer is too old or out of date.

Running slow is more of natural evolution than an issue if your computer has been in use for more than 5 years.

Due to the regular release of software updates, your computer will eventually fail to satisfy the minimal requirements for certain updates, forcing you to use old and obsolete software.

  • How to fix it: There are only a few options available to you. Choose a brand new computer, update the hardware on your current computer, or tolerate working with a slow machine.

Hardware Failure on a Computer

The hard drive, RAM, and CPU in your computer are all susceptible to harm. If none of the aforementioned concerns are the cause of your computer’s slowness, hardware failure may be on the way, resulting in a slowdown.

  • How to fix it: It is recommended that you get assistance from computer support or an IT specialist.
