What to do When Your High-End Computer is Running Slow

Some people work day and night to save up and buy the latest and the greatest computer hardware. They want the latest and greatest graphics card, and they want that fastest processor. They set up their computer, and immediately have this nagging feeling that it’s not going to work as well as it could.

When your PC is slow, it can be frustrating. This can happen to all of us sooner or later.

Since it’s release almost 2 years ago, latest version of Windows has been one of the fastest operating systems in the market. And this latest update, Windows 10, has even been hailed by some as the “best Windows yet”. But what happens when Windows 7 on a system with an Intel i7-4700 processor—one of the fastest available—is running slower than it should be? The answer is simple—you turn to Google.. Read more about computer running slow windows 10 and let us know what you think.

So you’ve spent all of your hard-earned money on a computer with some great specifications on paper. When you see that performance is inadequate or that you have to wait for things to happen when you shouldn’t, your heart falls. But if you know why it continues occurring, you may be able to solve the issue. 

When your high-end computer becomes sluggish, perform a virus check, clear the hard drive, and disable temporary files. A bottlenecked CPU, a damaged hard drive, or a full browser cache are all potential reasons (especially Internet Explorer or Google Chrome).

Please note that this essay focuses on PC performance issues rather than internet connection speed.

So let’s take a look at what makes a high-end computer so sluggish, and what you can do to make your machine faster and less prone to performance and system problems.

What to do When Your High-End Computer is Running Slow

Why is your computer so sluggish, and how can you repair it?

Everything we’ll talk about boils down to one thing: how you utilize the computer. Your computer will undoubtedly accumulate virtual trash as a result of installing extensions, surfing the web, downloading applications, generating various kinds of files, and downloading all of your movies and music. 

Here are a few problems that may cause your computer to slow down.

Applications and programs that run in the background

When you press the start button on your computer, a number of applications begin automatically executing and preparing for usage.

However, when you sit down at the computer to work, all of these background applications are already running and using resources. 

Some applications even continue to function in the background after you close their windows, and you must manually terminate their processes. 

All of these background applications eat up your processing power and ultimately slow down the programs you’re really using. 

The most frequent illness slowing down your laptop, according to Aaron Schoeffler, a computer repair doctor at LaptopMD, is starting applications that compete for resources and slow down your machine. 


On your Mac or PC, deactivate auto-start for unneeded applications to fix this issue and boost speed. Depending on the computer you’re using, here’s what you should do:

PC (Windows)

Close any applications that are running in the background using Windows Task Manager. Select Task Manager by pressing Ctrl + Alt + Delete on the keyboard.

Then, in the left-hand bottom corner, click on additional information. After that, you’ll get a list of all the applications that are taking up your RAM and memory. 

Click the startup tab at the bottom of the task management window to find startup applications. Then, close any starting programs that are no longer needed. 

From here, you can check which programs are resource-intensive and affect the computer’s performance if left running. Now sort out the programs to be closed and click on the end task to complete them.  

If you want to see an example of how to accomplish this, watch this video:



In the machine’s system settings, you may need to configure login items. Go to Applications, then Systems Preferences, User Groups, then Login Items, for example.

This will provide a list of all the applications that have an impact on the computer’s speed. Now you must uncheck any applications that are no longer required. 

Delete or transfer any desktop icons that you don’t use to the trash. If you still require the files on your desktop, you may transfer them to the proper directories. Here’s a video showing how to accomplish it:


It’s worth noting that certain background applications are required for your laptop to function properly. As a result, before you stop any possibly unneeded processes, be sure you know what they are. 

Infection with malware

Viruses and malware may degrade the functionality of your computer. They may hijack your browser, send you to phishing or advertising sites, and even damage your computer.

Simply reading emails from unknown or suspect senders or downloading files from strange and dangerous websites may infect your machine. 

Some malware simply slows down your computer by displaying annoying advertisements or stealing hardware resources, while others may enable hackers to steal sensitive data from your machine. 


We strongly advise you to install a good antimalware and antivirus software on your computer. Here are some of the most effective antimalware and cybersecurity solutions available today:

Furthermore, do not read emails from sources you do not trust or visit untrustworthy websites. 

PC (Windows)

To remove malware, open the search bar on your computer and then type Security into the search box and click Open. Next, select Virus & Threat Protection and then click Quick Scan. 


This is a step-by-step tutorial on how to scan your Mac for malware.

If all else fails, make a backup of your most essential data and reinstall your operating system from scratch after performing a full format of your HDD or SSD.

Do you have a problem with your hard drive?

1627781459_887_What-to-do-When-Your-High-End-Computer-is-Running-SlowA hard disk drive that is mechanical.

The temporal lobe of your computer/laptop is the hard disk. It’s the spinning disk that uses magnetism to store your data in binary code. Your computer will most likely slow down if it is not in good working order. 

It may be that the hard disk is approaching the end of its useful life, that there is no more room available, or that it is just obsolete and needs to be upgraded.

In any case, any of these issues may be the cause of your processor’s slowdown.


The first step is to examine the hard drive. Determine how much space is left on the hard disk. If the storage isn’t the problem, look for any other problems with the hard drive. 


Right-click on the drive, choose Properties, then Tools / Check Now from the menu on the left. Select “Scan for and try recovery of faulty sectors” from the drop-down menu.

This will prohibit your computer from accessing the hard drive’s “bad” regions. Wait for the computer to complete the scanning process. 


This video explains how to scan your Mac’s hard disk in detail:


Avoid any kind of hard drive impact to prolong the life of your hard drive. Consider switching from a hard disk drive to a solid-state drive (SSD).

Too many temporary files are clogging up your hard drive.

When you make a change to a file, the computer saves a copy for you (a temporary file). Temporary file extensions are typically preceded by the word “temp.”

Unfortunately, even after quitting the application, some systems do not remove these files. As a consequence, these files use a lot of storage space and ultimately cause your computer to slow down. 


You must manually remove these files to avoid this. To begin, go to your computer’s search box, enter Disk Cleanup, and then click Open.

Click on the disk you want to clear in the pop-up window, then on the Temporary Files box. A file list will appear. 

You may remove all the temporary files in storage that are using memory from here. 

Bottleneck in the CPU

Even if you aren’t a gamer, a CPU bottleneck may occur on your PC. This occurs when the computer processor is unable to keep up with the demands of particular programs.

Furthermore, combining a low-grade CPU with high-end devices may result in a CPU bottleneck. 

Using a super-fast graphics card on a low-end desktop CPU, for example, is unlikely to function effectively. Similarly, even if your GPU is more than adequate, you may experience decreased performance while playing CPU-intensive games.


To effectively solve the CPU bottleneck, you must first understand what is causing it. It is simpler to detect if you are utilizing modern gear. However, if the slowdown is caused by an installed application, you must investigate to determine which software is at fault.

It may be possible to fix the issue by ensuring that the applications you run on your computer and the processor you use are compatible with high-end equipment.

At a minimum, attempt to close the performance gap between your system and the CPU. 

Clear the cache and cookies in your browser.

Every time you visit a website, a cache is generated and saved. These files are saved in your Temporary Internet Files folder as tiny files.

Cookies record your personal information and surfing history, and over time, this information accumulates and takes up a lot of memory space. 


Clear your browser cache and cookies on a regular basis to enable your browser to load sites quicker and minimize the amount of storage they may use. 

Depending on which browser you are using, you may find these settings under the Settings menu, History, then click on Clear Browsing Data (some browsers label it Clear Cache & Cookies). Finally, click on confirm to delete the cache and cookies.

Slow performance on a high-end laptop


You may corrupt the hard disk of your high-end laptop, whether it’s new or old, by making a few beginner errors. Fortunately, most of these errors may be corrected.

Run a malware scan on your high-end laptop to check if any dangerous viruses have been downloaded.

Another option is to make sure your laptop fulfills all of the criteria for the games and applications you’re using (RAM, storage, graphics cards, etc.).

Because laptops quickly become obsolete after a few years, it’s recommended to just run one RAM-intensive application at a time and close old files while not in use.

High-end The computer is operating slowly.


Because you can remove and replace components on high-end PCs, they are frequently preferred over laptops. If you keep adding new components to your computer, it won’t become obsolete.

Check for malware after ensuring your PC fulfills all of the application requirements, just like you would with a high-end laptop.

If you constructed them yourself, you should double-check the components’ compatibility. Many PC components are incompatible, causing them to overheat or slow down.

To see whether your components are compatible with each other, use PCPartPicker’s System Builder tool. You may also learn more about compatible computer components by reading this page.

How to keep your computer from becoming sluggish

Prevention is always preferable than cure, as the adage goes. There are few things more aggravating than a sluggish computer. A sluggish computer processor is accompanied with a slow internet connection. These two are capable of making you pull your hair out in frustration.

To assist you avoid experiencing this annoyance, here are some ideas and techniques that have proved to be effective in avoiding computer slowdown. 

Installing unneeded software is not a good idea.

Random program installation interferes with your computer’s performance, causing it to slow down or even crash. 

It’s also a good idea to go through your applications on a regular basis and delete any that you haven’t used in a while. Avoid storing applications that you don’t use since they will only take up space on your computer and provide no value. 

When installing a new application, pay close attention. Unfortunately, in order to earn a fast profit, some software providers add random toolbars and other resource-hogging applications in their apps. 

Instead of rushing through the installation procedure without giving it any consideration, take your time and focus on what you’re doing. Uncheck boxes for any additional features that are added to the program. 

Install a fast SSD and upgrade your computer’s RAM.

RAM is responsible for storing all of the applications that you are now utilizing. A computer’s short-term memory is what it’s called. The minimum amount of RAM required to operate a computer for daily usage should be 4 GB. 

However, if you use your computer for gaming or other resource-intensive tasks such as video editing or programming, you should consider upgrading your RAM before your computer’s performance degrades. 

One of the limiting elements of your long-term computer memory is the good old hard drive. When you start an application, the hard drive must search for those files one byte at a time before transferring them to RAM. 

As a result, it is anticipated that this approach would be inefficient and time-consuming. Switching to an SSD (solid-state drive) is thus recommended if you want your computer to run faster. 

Although an SSD is usually included with your high-end computer, you should consider purchasing one if you don’t already have one. 

A solid-state drive (SSD) is a digital replacement to the hard disk that has greater horsepower and performs more efficiently. Furthermore, it is at least 10 times quicker. As a result, as compared to a hard drive, your files will process and open considerably quicker. 

Install OS updates and reset your computer on a regular basis.

It is beneficial to your computer’s efficiency to apply operating system updates as soon as they are available, whether you use Mac or Windows.

These updates look for and fix any new security vulnerabilities that may allow malware to infiltrate your machine. You may configure your computer to automatically install updates or ensure that you update whenever a prompt appears. 

Also, reboot your computer on a regular basis. Rebooting allows the system to install and update applications that would otherwise be unable to do so while the machine is turned on. It also cleans up the computer and frees up RAM that has been sucked up by badly written applications. 

Run a disk defragmentation program.


A fragmented disk, on the other hand, has to work more harder and therefore slows down your computer. Disk defragmentation will aid in the reorganization of fragmented data and the storage of it in a single location.

It also guarantees that all applications are in one location, as well as any unused space on the hard disk. Your disk will operate more effectively as a result, and your computer will run considerably quicker. 

A disk defragmentation can be scheduled, but it may also be done manually by going to My Computer (or This PC), right-clicking on the Hard Drive, and then selecting Properties. Then choose Defragment Now from the Tools menu.

Note that although this method works for HDDs, it isn’t ideal for SSDs. Disk defragmentation may damage a solid-state drive, so don’t perform it if your high-end computer has one.

Don’t allow your boot drive become too full.

Keep an eye on the primary storage space and don’t wait until it’s full. Your computer need free space on disk C, which contains the operating system, in order to function properly.

If this space is 90% filled, the system won’t be able to generate temporary files and will have to delete and rebuild files on a regular basis, which consumes time and makes your system slower. 

Always ensure that there are at least a few gigabytes of free space on the boot drive. Keep track of your apps and constantly uninstall anything unnecessary. This will ensure that there is always free space on this drive. 

On Windows computers, use CCleaner regularly to clear away temporary files.

Please do not wait until mountains of trash begin to impair the functionality of your computer before cleaning them up. Instead, run CCleaner at least once a month to assist in the removal of trash.

It can also check the size of your register codes and alert you to any applications that are configured to execute on startup. This will assist you in determining which applications are unneeded and removing them. 

Macs are extremely good at self-maintenance and will most likely not need you to do this manually. 


A speedy and efficient computer allows you to make the most of your time and be as productive as possible. If you discover that your high-end computer is slowing down, follow the suggestions above to figure out what’s causing the issue and how to fix it.

Remember to run virus scanning software on a frequent basis to keep your computer secure. On any high-end computer system, one simple step may save you time, money, and aggravation.
