[Easy solution] How to check the cause when your PC suddenly becomes heavy and make it more comfortable

This time, we will explain the reasons why your PC suddenly becomes slow and how to solve them.

If your PC suddenly becomes choppy or stops working while you are using it, there can be various reasons. For example, if your PC cannot withstand the load for some reason, or if there is an internal malfunction.

In order to deal with these problems, it is necessary to properly identify the cause.

5 reasons why your PC suddenly becomes slow

If your PC suddenly becomes slow, the following may be the causes:

• There is a problem with the hard disk
• Out of memory
• infected with a virus
• Apps running in the background are causing the issue.
• Affected by the Internet environment

There is a problem with the hard disk

The reason why your PC suddenly becomes slow may be due to a problem with your hard disk.

If a problem occurs with your hard disk, it may affect access to your system and data, and your PC may become erratic or slow.

In this case, you need to check other drives besides the C drive to see if there is any problem with the hard disk.

Out of memory

Insufficient memory is one of the reasons why your PC suddenly becomes slow.

The amount of memory varies depending on the PC, but if it is insufficient, the computer may not be able to process all the data and the computer may run slowly.

Memory is used when you are using an application. Of course, memory is always used, but depending on the content of the application, it can consume a lot of memory. Does it match the recommended memory capacity of the application you are using? You may need to check that as well.

Also, if your PC suddenly becomes slow, there may be a memory shortage caused by recently installed applications. Just to be sure, it's a good idea to check it once.

infected with a virus

If your PC suddenly becomes slow, it may be infected with a virus.

Viruses can be transmitted via email, websites, or USB memory, and can cause various negative effects on your PC.
If you have any idea that you have accessed a suspicious email or website, you may want to suspect a virus infection.

Impact of apps running in the background

If your PC suddenly becomes slow, it may be caused by an app running in the background.

There are applications that are running inside your PC and affecting its operation even if you do not start them yourself.
If unnecessary applications are running in the background, they may be slowing down your PC.

Your PC may suddenly become slow due to a newly installed application.

Affected by the Internet environment

If you suddenly feel heavy while viewing videos or sites, or playing games on your PC, it is likely that your internet environment is being affected.

The Internet environment differs depending on where you use it, and the line congestion also changes depending on the time of day.

For example, if you are downloading a video on one PC at night in your apartment while playing a game on the other PC, it may become slow due to line congestion.
This is because lines are often shared in residential complexes such as condominiums, and when the number of users increases at night, the lines can become congested.

Also, if you are using Wi-Fi, it is a good idea to check whether you are not too far from the wireless router.

How to check the cause using Task Manager

If your PC is running slow, you can try using the task manager to check the cause.

[How to find the cause with Task Manager]

1. Start task manager
   (Shortcut is Ctrl + Shift + Esc)
2. Check the Processes and Startup tabs to see if any unwanted applications are affecting your PC.

How to restore your PC to a comfortable state

Here are some ways to get your PC back to normal operation:

Take action depending on the cause.

• Replace hard disk or replace with SSD
• Add more memory
• Try uninstalling recently installed apps
• Inspect your PC with antivirus software
• Review your internet environment

Replace hard disk or replace with SSD

If your PC is running slowly, one solution is to replace the hard disk or replace it with an SSD.

If your PC is slow due to a problem with your hard disk or lack of space, you may want to consider replacing it.
You can replace it with a new hard disk, or you may want to consider replacing it with an SSD, which is said to be physically more difficult to break, instead of a hard disk.

Add more memory

If your PC is running slowly, one option is to install more memory.

As mentioned earlier, this method is effective if your PC becomes slow due to insufficient memory.

In order to add more memory, you will need to open your PC, so be sure to check the expansion method depending on the manufacturer and type of PC in advance.

Try uninstalling recently installed apps

If your PC suddenly becomes slow, uninstalling the application may be effective.

In particular, if your PC suddenly becomes slow, it may be caused by recently installed applications, so you may want to check if there are any recently installed applications.

[How to uninstall an application]

1. Select "Start"
2. Select "Settings"
3. Select "App"
4. Select "Apps & Features"
5. Select the appropriate application
6. Select "Uninstall"

Inspect your PC with antivirus software

If your PC suddenly becomes slow, using antivirus software may solve the problem.

This method is effective if the operation of your PC is adversely affected by a virus.

When you run a virus scan using antivirus software, if a virus is detected, it will remove it.

Review your internet environment

If you are experiencing slow performance when viewing videos or websites on your PC, it may be a good idea to review your internet environment.

If you are using the Internet at home, you may want to try other solutions such as restarting your modem. Another effective method is to change to an appropriate internet plan that suits your current usage.

If the communication environment improves, you will be able to watch videos smoothly.

List of ways to make your PC more comfortable

We will also explain how to make your PC run more smoothly.

I also explain the advantages and disadvantages, so I hope you find it helpful.

• Delete startup apps
• Delete background apps
• Defragment the hard disk
• Change power options
• Run if there is a Windows update
• Restart the PC

Delete startup apps

Disabling or deleting startup apps may solve the problem of a slow PC.

By minimizing the number of applications set at startup, you can get the benefit of making your PC lighter.

The disadvantage is that the application will not start when the PC starts, so you will have to start it manually.

[How to disable startup apps]

1. Select "Start"
2. Select "Settings"
3. Select "App"
4. Select "Startup"
5. Switch off the applications you want to disable

Alternatively, you can uninstall the application if you no longer need it.

Delete background apps

Removing applications running in the background may solve the problem of slow PC speed.

→How to uninstall an app

Or you can just disable background settings.

The advantage of this method is that it reduces the load on the system by reducing the number of applications running in the background.

The downside is that there may be apps that you don't know whether they are unnecessary or not, and you may end up disabling them by mistake.

So instead of disabling or deleting everything, it's best to only do it for things you clearly don't need.

[How to disable background apps]

1. Select "Start"
2. Select "Settings"
3. Select "Privacy"
4. Select "Background apps"
5. Switch off the applications you want to disable

Defragment your hard disk

If you want to solve the problem of a slow PC, one way is to defragment your hard disk.
Defragmentation means optimization, and it is the process of removing file fragmentation that may occur during the process.

Fragmentation simply means that one piece of data is split into different parts. If such fragmented data increases too much, the PC may become slow.

The advantage of defragmenting your computer is that it may speed up processing by tidying up your hard disk.

However, while defragmentation is in progress, you will not be able to perform other tasks, and depending on the capacity of your hard disk, it may take some time.

[Steps to perform defragmentation]

1. Select "Start"
2. Select "Windows Administrative Tools"
3. Select "Defragment and Optimize Drive"
4. Select the drive you want to defragment from the list
5. Select "Optimize"
   → “Running” is displayed, so wait.
6. Complete when "OK" is displayed
7. Select "Close"

Change power options

If your PC suddenly becomes slow, changing your power options may solve the problem.

The advantage of this method is that it is easy and does not require deleting or disabling the application.

The disadvantage is that the higher the power option, the higher the performance, but the higher the power consumption.

[How to change power options]

1. Right click "Start"
2. Select "Power Options"
3. Select "Additional power settings" under "Power & sleep"
4. Select "Change settings that are currently unavailable"
5. Select a plan (if "Display additional plans" is available, you can also display it by clicking)

Run if there is a Windows update (Update)

If your PC suddenly becomes slow, running a Windows update may solve the problem.

The advantage of this method is that it may not only run faster, but also allow you to benefit from new updates.

The disadvantage is that it takes time and you may not be able to use your PC during that time.

[How to check and update Windows Update]

1. Select "Start"
2. Select "Settings"
3. Select "Update & Security"
4. Check the status and select "Check for updates" or "Restart now" if available.

Restart the PC

If your PC suddenly becomes slow, one solution is to restart it.
Above all, performing a complete shutdown allows you to start up in a clean state, so it is worth trying.

To perform a complete shutdown, unlike a normal shutdown, hold down the Shift key while shutting down. Let's start it up after shutting down and see what happens.

The advantage of restarting your PC is that it is the easiest solution.

The disadvantages are that the problem may not be resolved if there are other causes, and that a complete shutdown may feel a little slower to start up than a normal shutdown.

Summary of reasons why your PC suddenly becomes slow

This time, we explained the reasons why your PC suddenly becomes heavy and how to solve it and make it more comfortable.
If your PC suddenly becomes slow, possible causes include insufficient memory or virus infection.
Other causes include accumulated fragmented data or applications running in the background.

Some people may be a little nervous because there can be various causes for PC problems, but please try each solution one by one.

First, you may be able to quickly resolve the issue by looking for the cause using the task manager, etc., and remembering whether you have recently installed any new applications or performed any unusual tasks.
