Why is My Computer so Slow

Table of Contents


It can be really frustrating when your computer starts to slow down, making even simple tasks feel like a chore. Understanding the reasons behind this sluggish performance is crucial in resolving the issue. There are several factors that can contribute to a computer’s slow speed, such as not having enough memory, having too many background processes running or even malware or hardware problems. By identifying the root cause, you’ll be able to take the necessary steps to improve your computer’s performance and regain a smoother computing experience.

Why is My Computer so Slow

Your computer—whether it’s a desktop PC, laptop or any other type—should always feel like a fast and responsive tool that keeps up with your productivity and creativity flow.
If you often find yourself having to pause your work because your computer takes a long time to finish tasks or if you’re constantly concerned about your computer freezing while you’re in the middle of something, it’s possible that computer performance problems are causing these issues.

How to Improve a Sluggish Computer

There are various factors that can contribute to a computer running slowly. However, the overall speed of your computer is primarily determined by three key components.
CPU; The central processing unit, also known as the processor, acts as the brain of your computer. Its performance is measured in gigahertz (GHz) and the faster it operates, the quicker your computer and applications will run.
RAM; Random access memory, commonly referred to as memory, is measured in gigabytes (GB) for capacity and GHz for speed. Having more GBs and faster speeds will result in smoother app performance and allow you to run multiple programs simultaneously.
Disk drive; Your storage drive, often called a hard drive, stores your apps and files when they are not actively being used. Its capacity is measured in GBs, while its read/write speed is measured in GBs per second.
If you exhaust these resources excessively, your computer may struggle to keep up with demands which could lead to extended loading times or even system crashes. To ensure optimal utilization of available resources, consider implementing these helpful tips.

Restart Your PC

When uncertain about what actions to take next, a simple restart can do wonders!
When your computer is in use, the operating system reserves memory space in RAM for various programs. If the RAM becomes full (for instance, due to having multiple browser tabs open), it can cause your computer to slow down.
To resolve this issue, a straightforward solution is to restart your device. This clears out the data stored in RAM and only reloads the necessary applications that your computer requires.
Here’s the paraphrased version;

Check Task Manager to Monitor Your PC’s Performance

Your computer has limited resources. If you have more programs running or larger files than your RAM, CPU and disk drive can handle, your computer will slow down.
To check how much of each resource you’re using, open the Task Manager. You can find it by searching in the Start menu or pressing Control, Alt and Delete simultaneously on your keyboard. Once the Task Manager window is open, go to the Performance tab. On the left side column, you’ll see a list of key resource components and their respective usage percentages.
If you consistently use over 80 percent of your RAM, CPU and disk space, it means your computer is handling more than it can handle efficiently. To improve this situation, consider freeing up storage space or adding more RAM or an additional storage disk drive. We provide various tips on these topics in this section. Additionally, if your CPU is overwhelmed by the tasks at hand, upgrading to a new laptop or desktop with a faster CPU might be necessary.
Quick tip; Utilize Task Manager to close any unnecessary applications to potentially give your computer a quick boost in speed.

Disable Startup Programs

Did you ever wonder which programs launch when your computer starts up? Many people are unaware, but having too many applications set to start automatically during boot up can cause performance issues on your PC. These applications run in the background without your knowledge.

Free Up Disk Space

If your computer’s hard drive is full or almost full, it can cause a slowdown in performance. The operating system needs enough free space to function properly, otherwise your PC may run slowly and it may take longer for your files to open.
Improving the performance of your PC can be achieved by freeing up some disk space. You can learn various methods to do this in our article on how to create more storage space on your computer. These methods include removing unnecessary files and applications, utilizing built in cleanup tools and exploring other storage options.

Pause OneDrive Syncing

When you use Microsoft OneDrive to store files in the cloud, your computer continuously syncs data between itself and the cloud. This ensures that your files are properly saved whether you access them from your desktop or a web browser. However, this syncing process can consume valuable computer resources and contribute to slower performance.
If you’re facing performance issues with your computer, temporarily pausing OneDrive syncing can help free up disk space and allocate more resources for improved speed. To do this, locate the OneDrive icon (resembling a cloud) on the taskbar near the notification area. Click on the icon to open its menu, then select “Settings” or look for the gear icon.
Find the synchronization menu to access your current settings and disable any options that you do not wish to sync automatically. In certain situations, you can also specify the duration for which you would like to temporarily pause the syncing of your files.


In summary, a slow computer can have a significant impact on productivity and lead to unnecessary frustration. By recognizing the different factors that could be contributing to the slowdown, you can effectively address the issue and implement appropriate solutions. Whether it involves increasing your memory capacity, removing malware infections or optimizing system settings, taking proactive measures to tackle the underlying causes of a slow computer will result in noticeable improvements in its speed and overall performance. By maintaining a well functioning system, you’ll ensure a seamless computing experience and maximize efficiency without constantly dealing with sluggish performance.
