Why is my pc so slow and how to fix it? If you find yourself asking this question a lot, you’ve come to the right place.

A slow computer may make even the simplest chores challenging, whether you want to play a game, finish work, or go shopping. There are many different causes why your computer may be operating more slowly than before. Don’t sit there thinking “Why is my computer slow?” because this is a fairly common problem, and there are several ways to fix it. Instead, take action.

Why is my PC suddenly so slow?

Before we attempt to speed up your slow PC, let’s go through a few potential causes for its possible sluggishness. A sluggish machine could be plagued by viruses or just require cleaning.

Remember that your operating system connects your machine’s resources and supplies energy to the many programs you use every day. With a PC, there is a tonne of background processes running all the time that can occasionally slow us down. That said, this usually only becomes apparent on a dated or underpowered PC.

main reasons why a computer is slow:

  • old system
  • Entry-level specs
  • an overheated CPU
  • A virus or malware
  • Ram that’s not enough
  • There is not enough room for storage
  • running too many background processes
  • Too many open applications
  • keeping your PC running nonstop

The ideas listed below can be utilized by individuals to help accelerate a computer, make it run quicker, or identify why a computer system is running gradually. Please realize that this internet site just addresses normally slow computers; it does not attend to computer systems that start gradually or have slow Web connections.


Before completing any of the instructions below, make sure to reboot your computer if it hasn’t been done recently. Restarting the computer is a simple first step that can solve many issues.

Background Programs

Programs operating in the background are one of the most common causes of a slow computer. TSRs and starting programs that launch automatically each time the computer boots should be removed or disabled.

Open Task Manager to check what programs are now running in the background and how much memory and CPU they are consuming. Run Resmon if you are using Windows 7 or a later version to better understand how your computer’s resources are being used.

Check to see whether your antivirus scanner, spyware protection program or other security tool is not checking your computer in the background. While a scan is running, your computer’s general performance suffers. Allow the scan to finish if this is the case, and the computer’s performance should increase.

Trash temporary files

On the hard disc, temporary files are kept while a computer runs programs. These temporary files can be deleted to enhance computer performance.

Windows systems

First, we advise deleting temporary files and other files from the computer using the Windows Disk Cleanup tool. Unfortunately, not all files in the temp directory may be deleted by the disk cleanup. As a result, we also advise manually removing temporary files.

  • Enter %tmp% in the search field after opening the Start menu or pressing the Windows key. ( Note: Type %tmp% in the Run box on Windows XP as well as prior by clicking the Run alternative in the Beginning food selection
  • Once you hit Enter, the Temp folder should open.
  • All of the files located in this folder can be erased, and any that are currently in use and unable to be destroyed can be skipped.

Free hard disk space

See to it there is 200– 500 megabytes of offered area on the hard drive. This available space enables the computer to store temporary files and allows the swap file to increase in size.

fragmented or corrupted hard drive

Look for errors on the hard disc.

Run ScanDisk, chkdsk, or a similar program on a Windows machine to make sure the hard drive isn’t physically broken.

Using Microsoft ScanDisk.

Check the hard disc for faults with the Disk Utility program on a macOS machine by selecting the First Aid option. Activate the Disk Utility by:

  • On the dock, select the Launchpad icon.
  • Open the Other folder, and then.
  • The Disk Utility can be opened by clicking on it.

A fragmented hard drive should not be used.

To help ensure that data is organized in the best way possible, run Defrag.

Hard drive test

Examine the SMART of the drive as well as utilize extra software tools to check for any mistakes on the hard disk drive.

Run a virus check

Your computer system could operate extra gradually if it has one or more infections on it. Run the complimentary online House call energy from Pattern Micro to check as well as eliminate infections from your computer if it doesn’t already have an antivirus program installed. To actively safeguard on your own versus infections, we likewise recommend making use of an antivirus program.

Run a malware check

Today, malware such as spyware is a significant contributor to numerous issues with computers, consisting of poorer performance. We advise doing a malware scan even if the computer currently has an anti-virus scanner installed. To inspect your PC for malware, make use of Malwarebytes’ free version.

Hardware issues

Verify that there are no conflicts in the Device Manager. If any problems exist, fix them because they might be the root of your issue.

Update the operating system (OS)

Run Windows Update to update a computer running Microsoft Windows Run Software Update to perform an update on a macOS device. Use the App Store to update the operating system.

Disable browser plug-ins

Consider turning off any browser plug-ins, add-ons, or extensions if your computer is noticeably slow when you use your online browser.

Update your drivers

See to it your computer hardware is running one of the most recent drivers, specifically one of the most recent video clip chauffeurs. Having actually obsoleted drivers can lead to several issues, including weak performance.

Reboot the computer once again

Restart your computer after making any of the above modifications.

Apply a registry cleaner

(Note: This part can skip if you own a Mac computer because there isn’t a registry in macOS.)

Typically, we do not advise using registry cleaners. But if you followed all the recommendations and your computer is still slow, you might need to consider using a registry cleanup.

Upgrade RAM

You may require even more RAM if your device is older than two years. For a 32-bit system, we suggest that PCs have a minimum of 2 GB of memory (RAM), and also for a 64-bit system, 4 GB. Your computer doesn’t need to swap information stored in memory to the swap file since it has enough memory for programs to run in memory. If the hard drive light is on all the time, the computer is likely to often transfer data between the hard drive and memory.

Upgrade the hard drive

Upgrade the hard drive.
The hard disc drive is just one of a computer’s main traffic jams. The performance of a computer can be substantially improved by changing from a normal hard disc (such as a 5400 RPM model) to a solid-state drive (SSD).

Overheated computer or processor

Check out whether your computer’s cpu is overheating. The efficiency of the computer can deal with unrestrained heat because many os immediately limit the cpu’s rate to assist stop heat-related troubles.

A computer could overheat if the essential air flow restricts inside by products like dust, dust, and hair. Ensure the fans aren’t obstructed which the PC instance is spotless.

Accelerate or upgrade the processor

Your computer’s efficiency might enhance by accelerating the processor (CPU). Overclocking or upgrading are both strategies for enhancing processor rate. A processor is overclocked when its speed is increased above the level at which it can run accurately. 

While overclocking can boost the processor’s rate, the boost is usually not extremely noticeable, only raising the speed by a maximum of 10% or 20%. The CPU itself must have the ability to overclock too. You would require to find your computer’s processor’s specs to figure out if it can overclock. Because an overclocked processor creates even more heat, so a stronger warm sink and also follower are needed to remove the added warm from the cpu.

Erase the computer plus start over

Re-installing the OS or beginning again are other alternatives if none of the above procedures function to fix your troubles. Removing out-of-date software or vehicle drivers, getting rid of whatever on your computer, and also re-installing the os can enhance performance.

A fresh setup of macOS or Windows, software applications, and also one of the most newest drivers can all be set up to ensure your maker isn’t being slowed down by software-related troubles.

Hardware problems

Last but not least, if your computer is still slow after trying the above suggestions, there might be an extra significant hardware-related trouble (e.g., failing element). 

The motherboard, CPU, RAM, hard drive, and other equipment elements are some examples of probable defective components.

Aging System

Your computer will work less actively than a new one if it is older than five years. Newer computers can perform more latest software programs effectively thanks to optimization. Aging Solutions run much more gradually because they can not perform these modern-day programs also. An additional issue with out-of-date equipment is that modern software program typically has higher demands. We suggest you consider obtaining a latest PC or upgrading your existing one.

Final Thoughts

You don’t need to make any significant adjustments to speed up a slow computer. You’ll experience instant and long-lasting effects with a few simple, manageable changes. It’s not necessarily the end of the world if your computer has suddenly started to run slowly. When your computer is running slowly, you might think it’s the end of the line. However, the solutions mentioned above can help you get more use out of your machine and save money. Upgrades are costly, and with the present stock problems the computer industry is experiencing, it makes sense that some people would want to get the most performance possible from their parts.

Your desktop or laptop may need to be completely reformatted (rebuilt from scratch) or upgraded if the initial methods don’t speed them up. Upgrades are expensive and reformatting is the last resort, but we hope this article might at least temporarily reduce some of the stress.
