Why Is My Computer Suddenly Slow? (10 Potential Reasons)

There are few things as frustrating or annoying than a computer that isn’t working properly.

The computer is turned on while you wait for your operating system to boot up.

You were using the computer last night without issue but then you notice that suddenly it’s becoming slow?

Although it isn’t unusual, is a signal that something is not right, and typically occurs due to specific causes.

Here are the top 10 most frequently used.

Why Is My Computer So Slow All of a Sudden? (10 Potential Reasons)

1. Your Computer Might Have A Virus

The virus world is full of flavors However, a majority of them could cause your computer to slow.

Certain forms that are malware (unwanted malicious software) try to go undetected and make use of as few computer resources as they can.

Other viruses can render your computer inaccessible until the virus is completely eradicated.

However, even the most lean of viruses leave a kind of trace on performance.

A few indicators of malware include unanswerable pop-ups that pop up frequently or browser redirects while surfing the internet, and even modifications to your system’s settings that you did not do.

If your PC is slow suddenly and you think a virus could be at fault Open the performance monitor to get an overview of what’s taking the system’s resources.

To do this, launch your Task Manager by pressing shift + ctrl + Es on your keyboard, and then click to open”Performance”. “Performance” tab.

The majority of the time (but usually, but not all the time) or insufficient storage or flashy disks are main problems that affect the performance of your computer and performance, so make sure to check these first.

Performance Monitor will give you an instant overview of what hardware may be causing problems and you can provide additional details within Resource Monitor.

To launch the application to open the application, click “Open Resource Monitor” at the end on the “Performance” tab.

With Resource Monitor, you can find more specific information on what processes are taking up all your CPU, RAM, and disk usage , in addition to other things.

If you notice a particular procedure that requires a lot of resources, you may have identified the source.

If you aren’t sure if it is A quick Google search for the program’s name will tell you whether the application is genuine.

If you think you may be infected, you should use an antivirus program that is reliable, and check your computer for any suspicious software.

Once you have completed the test, recommend that you use Malwarebytes because it is a great complement to the AV software for detecting and getting rid of malware.

Certain virus require complete formatting as well as Reinstallation on the operating System Be prepared for the possibility.

2. Low Disk Space

How much disk space do I have?

If you’re HDD is filled or nearly full, you may observe your computer’s performance slowing as well as other irregular behavior, such as freezing or crash.

A fully-loaded hard drive may create problems for operating systems due to various reasons.

First, the OS utilizes an area of hard drive space as virtual RAM, also known as the swap file or page file.

To free up memory to be used for immediate purposes in the future, the OS will temporarily transfer RAM data onto the hard drive for them to be recovered and loaded to memory whenever required.

Your computer is able to reserve space on your hard drive for this purpose, however the swap file either grows or shrinks based on the amount of space required.

If space is not sufficient to limit what size the file can be your computer will be unable to use RAM effectively.

Furthermore, a full hard drive is an less efficient one.

Indexing takes longer and is more time-consuming as well as the hard drive may become more fragmented as there’s not enough space to move old files.

With the advent of solid state drives this becomes less of an issue, but every millisecond wasted can be a significant loss.

If you find that your system is running low in storage, you should work on eliminating or removing unnecessary files.

Be sure to clear the recycle bin as well as your downloads folder, since they could be storage areas for many files when you don’t clean them up.

If you’ve cleared all the obvious data but are still unable to meet your storage capacity You can test Windows 11’s built-in utility known as Storage Sense.

This tool can tidy up temporary files and directories.

Another tool we love is known as CCleaner from Piriform.

3. Corrupt Operating System

A damaged operating system could cause your computer to slow down without any warning.

What causes an unsound OS?

There are a myriad of reasons such as bad updates or incompatible drivers can cause OS corruption, however an of the prevalent causes of this is a malfunctioning shutdown.

If you make your computer to shut down while it is accessing system files, your chance of running into operating system issues is extremely high.

Broken OSes are often visible as the famous”blue screen” (for Windows), but other issues could be present also.

It could take your computer some time to start or not even start in any way.

If your computer is able to start up properly, there could be some issues that will not appear until you attempt to access certain programs or do some specific task.

If you think this could occur, here are some things you could try.

To begin, open an command prompt within Windows.

Click the Start button and then in the search box start by typing “command prompt” until the program begins to show up in the results of your search.

Right-click the program and select “Run as administrator.”

Once the prompt is displayed when the prompt opens, type the following command and hit”Enter.” “Enter” key:

DISM.exe /Online /Cleanup-image /Restorehealth

DISM is the acronym for Deployment Image Servicing and Management in addition,”online” refers to Deployment Image Servicing and Management. “online” switch utilizes files taken from Windows Update to download necessary files to repair corrupted files.

After the first command has been completed, we’ll utilize SFC, the system file Checker (SFC) in order to search for and fix the corrupted file:

sfc /scannow

Take your time as these two commands can take a while, particularly when your system is operating at a slow pace.

4. Your Hard Drive Is Failing

One of the most frequent reasons for a computer to be slow is a failed hard drive.

This is particularly the case if your primary drive is mechanical. However, any solid state drive will can fail.

Sometimes, a damaged hard drive can be difficult to determine because issues can be intermittent or intermittent, particularly if just a few sectors are damaged, while the remaining drive remains in good condition.

I’ve observed systems that start up and function according to plan, and then be stymied when the OS connects to a specific service or dll in the wrong sector.

One method of identifying problems is with the appropriately called Check Disk utility.

Start the command prompt once more and type this command

chkdsk c: /r

In the event that Windows has been installed in a separate volume substitute”c” “c” with the letter you have assigned to the Windows partition.

Since the disk is being used for use by OS OS, Command Prompt will ask you if you’d like to start Check Disk at the next boot.

Enter “y” and hit enter. Then, restart your computer.

Based what size your computer is the process can take time, so you should be patient.

The /r switch allows Check Disk to attempt to “repair” errors however, this typically consists of the identification of bad sectors, then coning them off to ensure they never be repeated and (if it’s possible) transfer the data to the right sector on the disk.

Another method to test the drive for issues is to use diagnostic tools.

A lot of PC makers have built-in dialogs allow you to access them prior to boot using a hotkey keyboard.

In the absence of this it is possible to utilize third-party software which work in and outside of the OS.

If the diagnostics indicate issues with your drive, make sure you back up your files and replace the drive as soon as you can.

5. Too Many Background Services Running

 

Are you noticing a variety of applications that start up every time you login to your PC?

If this is the case, you could be running too many processes and processes running.

The majority of the programs will have minimal impact on the performance of your OS however, they could increase as you install more programs in time.

Since the results of this issue are in a way, if your computer starts to suddenly slow it’s possible that a single application can be causing your computer to slow down.

The cause could be an app that consumes a lot of resources or one that is poorly written.

If you think this could be the reason for the sudden slowdown, think about the programs you’ve installed in the last few days.

Remove them one by one beginning with the most recentversion and test them after each install to see if the computer gets back to normal.

If you require these software, the best way to go is to make sure they don’t automatically run at the first startup.

This ensures that the program only runs whenever you’re required to use it, which means it doesn’t consume resources that are running in the background.

To verify the startup program To check for startup programs, we’ll visit Task Manager like we did in the previous example However, this time select”Startup”. “Startup” tab.

You can click on the “Status” column heading to sort the programs according to the degree to which they run automatically upon first logging in.

Check for any settings in the state of “Enabled” and remove any aren’t required to run on autopilot.

6. Overheating

Computers produce a lot of heat.

An average CPU is operating between 100 degF to 150 degF (38degC between 66 and 38degC) Other components such as graphics processors (GPUs) only compound the issue.

Thus, if the PC isn’t able to properly disperse heat — whether either passively or actively, it could slow down.

Certain sophisticated chipsets may tell components to slow down during overheating conditions to protect them from damaging the components.

If this happens on your PC you’ll notice a slow performance.

Because the CPU is often the component that is the most hot that we can examine processor temperatures to get an picture of the general temperature of the computer.

A great method to track CPU temperature is by using this free HWMonitor program based on the CPUID..

Install and download the program and then launch the program and find your processor.

Click the plus sign to increase the amount of information available, and you’ll find the section that has temperatures.

Temperatures above 150 degrees F could be a sign of trouble You don’t want to have your CPU temperature above 200 degrees.

A sudden increase in temperatures may indicate an issue with your fan, which could mean which means that the air vents have become blocked blocked or there is not enough temperature paste that is between your processor and the heatsink.

The best option for resolving the issue is to utilize an air compressor to blow dust and lint from your system.

If the CPU isn’t cooling as fast, or you’re experiencing excessive temperatures Check your fans.

The no-cost Speed Fan software can assist you in monitoring the speed of your fans, and you must also run diagnostics if your computer has these to make sure that the fan performance is in good order.

7. Other Hardware Issues

Alongside problems with the hard drive and other hardware malfunctions can cause slow computers.

This is particularly the case If there are problems in your CPU, RAM or GPU.

With RAM the RAM could be defective and cause issues when the computer tries to deal with the affected areas.

In addition to the slow performance, you may also encounter blue screens as well as shutdowns or abrupt reboots.

Sometimes, you’ll be able to see an indication of the issue, but it’s not always the case.

An excellent test to determine memory is Memtest86..

Don’t fall for the name, even though.

Apart from x86 architecture it can use ARM chips too.

Download the program to extract and then zip the file.

Inside, you’ll find an executable program that can be used to build USB drive that can boot. USB drive.

You’ll have to start your system from this drive to ensure that the utility has complete access to the memory.

Motherboard issues can be difficult to identify since they can be manifested as similar to OS issues.

Try restarting your OS and then watch for the problem to occur again.

If you own an individual GPU, consider removing it from your system as soon as you can to determine if the issue disappears.

8. Network Issues

Does your computer have a slow performance only when you attempt to connect online?

The issue could be related to your internet connection.

An low speed Ethernet or WiFi connections can create the impression that your computer isn’t running smoothly since nearly everything you do on your computer nowadays is dependent on the Internet.

For testing, try to use a program on your system that isn’t dependent on the internet, such as music player with MP3s that are that are stored within your computer’s hard disk, or viewing and editing images or using an word processor to write documents.

Is your computer running at a slow speed?

If it isn’t, then your network connection may be having issues.

If this is the case, it’s crucial to identify if the issue is external or internal for your system.

If you are able change networks or move your computer to another place to see if the network connection is improved.

You can go to speedtest.net to test your Internet connection prior to and after the change.

If you have less than 25 Mbps will likely appear slow.

If you are experiencing issues with your network, call you Internet service provider , or the network administrator to get help.

If the issue appears to have something to do with your computer the most likely culprit is a missing, outdated or damaged driver.

Visit the manufacturer’s site to download and locate the most current network drivers.

(You might need to transfer this information to another computer if the connection you are using is especially damaged.)

It’s also important to note the possibility that an Internet browser may be the cause, even the drivers and network are in good order.

To test the browser, try another one.

If you use Edge, download Chrome.

If you use Chrome, try Firefox.

If the issue is with your browser’s fault, then it’s likely that you’re using a faulty extension or plug-in that’s creating the problem.

9. Outdated Or Corrupt Drivers

Alongside bad driver for your network, malfunctioning or insufficient drivers for all hardware components could cause your computer to be slow to run.

Most likely culprits are chipsets, hard drive controllers and hard drive drives as well as graphics card drivers.

If you suspect that there is a driver problem, first go on Device Manager.

Start a Run dialog box by pressing the Windows key while pressing the “R” key.

After that, type devmgmt.msc and press “Enter.”

In the Device Manager In Device Manager, look for devices that have an exclamation mark beside them.

The icon signifies a malfunctioning or damaged driver.

Even even if you don’t have exclamation marks, you may still be experiencing a driver issue because Windows might have installed a basic version that is a driver however the proper driver isn’t installed.

The most efficient way to download drivers is to get them directly from the PC manufacturer.

Visit the support website of the company as well as search by your model number.

If you designed your own PC, you can try to identify the component that requires an updated driver . Then, visit the site of the manufacturer.

If you’re not certain what device is the culprit Start by examining your chipset (motherboard) and then move through the remaining devices.

10. Antivirus Scanning

The antivirus software is essential to protect your computer from infection by viruses, however antivirus software can also consume a lot of resources particularly when it is the process of scanning your computer.

In addition to the real-time monitoring provided by the majority of AV programs All good security software will also run scans of your memory and hard drive for suspicious activity and files.

However, scanning may make your computer crawl.

If you notice that your computer is slowing down, start Task Manager and look at the use of your disk.

Select the “Disk” column within the “Processes” tab to find out which programs use the disk.

If your antivirus is taking up the disk, it’s probably searching for malware.

Scanning is crucial therefore, don’t stop routine scans.

Instead, change the scan schedule to an hour that you aren’t working on your computer.

Conclusion

It’s easy to get dissatisfied when your computer starts operating slowly out of blue.

The issues are notorious of surfacing at the worst moments However, with a careful analysis of the symptoms you’ll be able identify and address the issue as a professional.
