How to find out why your computer is slow and use it comfortably

This time, we will explain how to solve the problem if your computer starts up or runs abnormally slow, freezes, or stops working.

There are several possible reasons why your computer may be slow, heavy, or not working.

First of all, it would be a good idea to find out why this problem occurred.

I also explained what happens when you just bought a computer and it's slow, so I hope you find it helpful.

Causes and solutions for abnormally slow computer startup

If your computer starts up or runs extremely slowly, the following may be the cause:

• How to find out the cause of a hard disk failure and how to resolve it
• How to find out the cause and solve the problem when memory is low
• How to check and solve if the problem is caused by the CPU

How to find out the cause of a hard disk failure and how to resolve it

If your computer starts up abnormally slowly, there may be a problem with your hard disk.

To find out if there is a problem with your hard disk, it would be a good idea to perform an "error check" and automatic repair using the method below.

[Error checking and automatic repair method]

1. Select the folder mark on the desktop taskbar
2. Right click on your hard disk drive
3. Select "Properties"
4. Select the “Tools” tab
5. Select “Check” in “Error Check”
6. Check "Automatically repair file system errors" and "Scan and recover bad sectors"
7. When the message "Do you want to check your hard disk for errors the next time you start your computer?" appears, select "Schedule a disk check".
8. Wait until the scan is finished

If the problem persists even after performing the above error check and automatic repair, please refer to "Check the health status of your hard disk or SSDPlease check to see if there is a problem with the hard disk.

If a hard disk failure occurs,How to replace a hard disk with an SSD and the costPlease replace the hard disk or replace it with an SSD using the method described in ``.

How to find out the cause and solve the problem when memory is low

If your computer's memory is low and usage is high, it may slow down your computer's startup and operation speed.

First, open Task Manager and check the memory usage.

You can display the Task Manager by right-clicking "Start (Windows mark)" and selecting "Task Manager."

In "Processes" in Task Manager, you can see the memory usage rate and check the breakdown of the usage by apps and processes. If the usage rate exceeds 80%, there is insufficient memory.

Also, in the "Performance" tab, you can check how many GB of memory you have and how much of it you are using.

If you find that memory usage is high in Task Manager, here are some possible solutions:

• Close software you are not using
• Close unnecessary startup apps
• Perform Windows update
• Add more memory
• restart
• Run an antivirus scan

Try these solutions and see if your computer starts up and runs faster.

How to check and solve if the problem is caused by the CPU

Similar to memory, high CPU usage can slow down your computer's startup and operation speed.

Right-click "Start (Windows mark)" → "Task Manager" to display the task manager and check the CPU usage rate.

If there is an application that is using a lot of CPU in the "Process" tab, you need to take measures such as closing it.

There are other solutions as well, such as:

• Perform Windows update
• Change power performance
• restart
• Scan with antivirus software

How to find out why your computer is running slow even though you have enough free space and how to solve it

There may be cases where your computer runs slow, doesn't work, or freezes even though you have plenty of free space.

In this case, the reason why your computer is heavy or slow may not be related to the HDD capacity.

If the HDD does not have enough space, the disk usage rate will increase and the computer will become heavier as a result. Therefore, if you have enough free space on your HDD, you should suspect other causes.

If the problem is not a lack of HDD space, but an abnormality or failure of the HDD itself, try the following solutions.

How to find out why your computer is slow to start even though you just bought it and how to solve it

If you have just bought a computer and are experiencing slow startup or slow operation speed, please refer to the information below.

• How to check and solve cases where insufficient memory is the cause
• How to check and solve if the problem is caused by the CPU
• Suspect initial failure

How to check and solve cases where insufficient memory is the cause

If you have just bought a new computer and it is slow to start up or operate, it may be due to insufficient memory.

Even if you just bought it, depending on the applications you use and how you use it, you may run out of memory.

Check the memory capacity and usage rate using the method below, and if there is a problem, try the solution.

How to check and solve if the problem is caused by the CPU

If you just bought a computer and it starts up or runs slowly, the CPU may be the culprit. It depends on how long it has been since you just bought it, but it might be a good idea to check just to be sure.

Additionally, it is a good idea to delete any unnecessary applications that are installed on your new computer.

Suspect initial failure

If you just bought a computer and it starts up slowly or is slow, it may be due to an initial defect.

The initial failure rate of computers is not very high, and seems to be around 1%. However, it is a possibility, so if you have just purchased it and it is slow, you may want to suspect an initial defect.

If checking the memory and CPU does not resolve the issue, it would be a good idea to contact the manufacturer and have them replace it if necessary.

How to find out why your computer is slow, not working, or freeze and how to solve it

There are various reasons why your computer may be slow, not working, or freeze.

Basically"Causes and solutions for abnormally slow computer startupPlease check the contents of `` and refer to the solution.

Also, if you are using an app on your computer and feel it is slow, please check the following items.

Check the recommended specs of the app you are using

If you're using a computer and it's slow, slow, heavy, freezes, etc., check the recommended specs of the app you're using.

Each app has ``recommended specs'' that indicate how well a computer can be used to comfortably use the app.

Light apps can be used without problems even if the computer specs are not that high, but heavy apps may not work well depending on the computer.

Apps that process a lot of images and videos, and 3D games will fall into the heavy category.

Therefore, it may be a good idea to check the recommended specifications of the apps you use frequently.

Recommended specifications can be found on the app's download page or official website.

If the required specs of the app are higher than the specs of your computer, you will need to change the app you are using or change your computer to match the app.

How to find out why your computer suddenly slows down and how to solve it

If your computer suddenly becomes slow or slow, there are many possible causes.

If you are aware of any of the causes listed below, please refer to the solutions listed below.

• Impact of recently installed apps
• Internet environment
• hard disk fragmentation
• It's temporarily getting heavier

Impact of recently installed apps

If your computer suddenly becomes slow or slow, check to see if you have installed any apps recently.

Depending on the apps you have installed, your computer may become slow or slow.

You may also want to right-click "Start (Windows icon)" and display "Task Manager" to see if any recently installed apps are putting a strain on your memory or CPU.

If you want to uninstall the app, try the following method.

[How to uninstall the causing application]

1. Select "Start (Windows mark)"
2. Select "Settings (gear mark)"
3. Select "App"
4. Select "Apps & Features"
5. Select the appropriate application
6. Select "Uninstall"

Internet environment

If your computer suddenly becomes slow or slow, it may be due to your internet environment.

Does your computer become slow, especially when using internet apps, searching the internet in a browser, or watching videos? At this time, if the screen freezes or if the page does not change easily and a spinning mark is displayed, the Internet connection may be poor.

Please check your internet connection status and try restarting your modem or changing your plan if necessary.

hard disk fragmentation

If your computer suddenly becomes slow or slow, it may be affected by hard disk fragmentation.

First, let's talk about fragmentation.

Initially, a hard disk stores files as a single unit.

However, as a hard disk is used for a long time and data is repeatedly deleted and saved, the areas on the disk become divided into smaller areas, and data is stored in the gaps between them.

Then, even if you want to retrieve one piece of data, you have to go to different places on the hard disk, which takes time.

Defragmentation is the solution to this fragmentation.

Simply put, defragmentation is the process of rearranging scattered data, and it can be said to be a process that should be performed regularly when using a hard disk.

The advantage of defragmenting your computer is that it can clean up your hard disk, speed up processing, and potentially make your computer run faster.

Also, there are some things to keep in mind when performing defragmentation. Please be aware that you cannot perform any operations while defragmentation is in progress, and that it may take some time to complete the defragmentation process depending on the hard disk condition.

[Steps to perform defragmentation]

1. Select "Start (Windows mark)"
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"
6. Wait because it shows "Running"
7. Complete when "OK" is displayed
8. Select "Close"

It's temporarily getting heavier

If your computer suddenly becomes slow or slow, there may be a temporary problem.

In this case, it is best to shut down your computer and restart it.

Performing a "complete shutdown" may solve the problem more than a normal shutdown.

Unlike normal shutdown, complete shutdown does not save the investigation status of peripheral devices when the power is turned off. As a result, your computer will start up a little slower, but if you are having problems, try this.

[How to completely shut down]

1. Select "Start (Windows mark)"
2. Select "Power mark"
3. Hold down the Shift key and select Shutdown

Summary: How to find out why your computer is slow and use it comfortably

This time, we have explained the causes and solutions for computers that are slow, heavy, or not working.

If your computer is running slow as mentioned above, it may be due to the recommended specs of the app or the memory, but if it is a newly purchased computer, it may be an initial failure.

It is also possible that the problem is not due to a problem with the computer itself, but rather to the internet environment. If you find that it is slow or slow when accessing applications, browsers, or sites that use the Internet, please review your Internet environment.

First, check to see if you have any idea what the cause is, and then try some simple solutions.
