Why Your Computer Might Feel Sluggish

Many factors contribute to a slow computer, and understanding these helps you choose the right solutions. Your computer acts like a busy office, and sometimes that office gets overwhelmed. Here are the most common culprits:

• Too Many Programs Running: Every program you open, even if minimized, uses your computer’s resources. When you have many programs open at once, your computer works harder, slowing everything down. Think of it like trying to read several books at once; your brain processes information slower.
• Full Storage Drive: Your computer stores all its files and programs on a storage drive (often called a hard drive or SSD). If this drive fills up, your computer struggles to find space for temporary files it needs to operate, leading to slower performance.
• Outdated Software: Operating system updates and software updates often include performance improvements and bug fixes. Running old versions means you miss out on these enhancements.
• Malware or Viruses: Malicious software (malware) can run in the background, consuming resources, tracking your activity, or even damaging your files. This significantly impacts your computer performance.
• Too Many Browser Tabs and Extensions: Your internet browser, especially with many tabs open or numerous add-ons (extensions), can consume a surprising amount of your computer’s memory and processing power.
• Old Hardware: Computers, like cars, age. Older components simply cannot keep up with the demands of modern software and internet speeds. If your computer is several years old, its hardware might be the primary bottleneck.

Don’t worry if these terms sound unfamiliar. You do not need to understand every technical detail. Focus on the actionable steps in this guide, and you will improve your computer’s speed.

Restart Your Computer Regularly

Restarting your computer is the simplest and often most effective first step for a slow computer. Think of it as giving your computer a fresh start. When you restart, your computer clears out its temporary memory (RAM) and stops all running programs, resolving many minor slowdowns. You should restart your computer at least once a week, or whenever you notice it acting sluggish.

For Windows 10 or Windows 11 PCs:

1. Look for the Start button in the bottom left corner of your screen. This button looks like four small squares. Press it.
2. A menu opens. Look for the Power icon, which appears like a circle with a vertical line at the top. Click this icon.
3. A small menu appears with options such as “Sleep,” “Shut down,” and “Restart.” Click on Restart.
4. Your computer will turn off and then turn back on automatically. This process might take a few minutes.

What You’ll See On Screen: The screen might go black, then you see the Windows logo, and eventually your login screen or desktop. The desktop is the main screen you see when you turn on your computer.

For Apple Macs (macOS):

1. Look for the Apple menu in the very top left corner of your screen. It appears as a small apple logo. Click it.
2. A drop-down menu appears. Click on Restart….
3. A small window might pop up asking if you want to reopen windows when you log back in. If you want a truly fresh start, uncheck this box.
4. Click Restart to confirm.
5. Your Mac will turn off and then turn back on.

What You’ll See On Screen: The screen goes dark, then you see the Apple logo, followed by your login screen or desktop. The dock is the bar of icons at the bottom of the screen.

For Chromebooks (Chrome OS):

Chromebooks are generally very fast and handle restarts differently. If your Chromebook feels slow, a simple restart can help.

1. Look at the bottom right corner of your screen where you see the time and battery icon. Click on this area.
2. A menu appears. Look for the Power icon, which appears like a circle with a vertical line at the top. Click it.
3. Your Chromebook will shut down. Wait a few seconds, then press the power button to turn it back on.

What You’ll See On Screen: The screen goes dark, then you see the Chrome OS logo, and your login screen. The bar at the bottom with icons is called the shelf.

Close Unused Programs and Browser Tabs

Every open program or web browser tab uses your computer’s internal memory and processing power. Closing things you do not actively use frees up these resources, helping your computer run faster. Think of it like decluttering your workspace; with fewer things open, your computer works more efficiently.

For Windows 10 or Windows 11 PCs:

1. Look at the bottom of your screen for the taskbar. This is the horizontal bar at the bottom. You will see icons for all the programs currently running.
2. Identify any programs you are not using.
3. Right-click (press the right mouse button once) on the program’s icon in the taskbar.
4. A menu appears. Click on Close window or Quit.
5. To close browser tabs: In your internet browser (like Edge, Chrome, or Firefox), look for an “X” on each tab at the top of the browser window. Click the “X” on any tab you no longer need.

What You’ll See On Screen: The program window disappears, and its icon on the taskbar might no longer show an underline or highlight, indicating it is closed.

For Apple Macs (macOS):

1. Look at the bottom of your screen for the dock. This is the bar of icons at the bottom. You will see a small dot or indicator beneath the icons of programs that are currently running.
2. Identify any programs you are not using.
3. Right-click (press the right mouse button once) on the program’s icon in the dock.
4. A menu appears. Click on Quit. If Quit is grayed out or does not appear, the program is not actively running.
5. To close browser tabs: In your internet browser (Safari, Chrome, or Firefox), look for an “X” on each tab at the top of the browser window. Click the “X” on any tab you no longer need.

What You’ll See On Screen: The program window disappears, and the small dot beneath its icon in the dock goes away.

For Chromebooks (Chrome OS):

1. Chromebooks manage resources well, but too many browser tabs can still slow things down.
2. In your Chrome browser, look for an “X” on each tab at the top of the browser window. Click the “X” on any tab you no longer need.
3. You might also see icons for open apps on the shelf at the bottom. If an app is running, you can right-click its icon and choose Close.

What You’ll See On Screen: The tab or app window disappears.

Manage Your Startup Programs

Many programs automatically start when you turn on your computer. While some are necessary, others are not and contribute to a slow computer startup and ongoing sluggishness. Disabling unnecessary startup programs means your computer has fewer tasks to handle right from the beginning.

For Windows 10 or Windows 11 PCs:

You use a tool called Task Manager to control startup programs.

1. Right-click (press the right mouse button once) on an empty area of the taskbar at the bottom of your screen.
2. A menu appears. Click on Task Manager.
3. What You’ll See On Screen: The Task Manager window opens. It might appear small; if so, click More details in the bottom left corner.
4. Click on the Startup tab at the top of the Task Manager window.
5. You will see a list of programs. Look at the “Status” column. If it says “Enabled,” that program starts automatically. The “Startup impact” column helps you identify programs that use significant resources.
6. Click on any program you do not need to start automatically (examples include Spotify, Skype, Adobe Reader, or printer software that you do not use daily).
7. Click the Disable button in the bottom right corner of the Task Manager window.
8. Close the Task Manager window by clicking the “X” in the top right corner.

Recommendation: Only disable programs you recognize and are confident you do not need running all the time. If you are unsure, it is safer to leave it enabled. Never disable essential system processes or antivirus software.

For Apple Macs (macOS):

On a Mac, these are called Login Items.

1. Click the Apple menu in the top left corner of your screen.
2. Click on System Settings… (on older macOS versions, this is “System Preferences…”).
3. What You’ll See On Screen: The System Settings window opens.
4. In the sidebar on the left, scroll down and click on General.
5. On the right side, click on Login Items.
6. You will see a list of applications that open automatically.
7. Click on any application you do not want to start automatically.
8. Click the minus sign (“-“) button at the bottom of the list to remove it.
9. Close the System Settings window by clicking the red “X” in the top left corner.

Recommendation: Similar to Windows, only remove items you are sure about. Removing antivirus software or critical system tools is not advisable.

For Chromebooks (Chrome OS):

Chromebooks handle startup items very efficiently. There is no specific “startup programs” menu like on Windows or Mac. Most applications do not run in the background. If you notice a slowdown related to startup, it is more likely due to browser extensions or too many tabs opening automatically. We cover browser extensions in a later section.

Clear Up Disk Space

A full storage drive significantly slows down your computer. Your computer needs free space to operate smoothly, create temporary files, and perform updates. Removing unnecessary files and programs frees up this crucial space, which helps your computer run faster.

For Windows 10 or Windows 11 PCs:

Windows offers built-in tools to help you manage storage.

1. Use Disk Cleanup:
   1. Press the Start button (the Windows logo) in the bottom left corner.
   2. Type “Disk Cleanup” into the search bar that appears and press the Enter key on your keyboard.
   3. What You’ll See On Screen: The Disk Cleanup window opens, asking which drive to clean. Usually, “C:” is selected, which is correct. Click OK.
   4. The tool scans your computer. Once it finishes, it shows a list of file types you can delete, like “Temporary Internet Files,” “Recycle Bin,” and “Temporary files.”
   5. Check the boxes next to the types of files you want to remove. You can often safely check most of these.
   6. Click OK, then click Delete files to confirm.
2. Uninstall Unused Programs:
   1. Press the Start button.
   2. Click on the Settings icon, which looks like a gear.
   3. In the Settings window, click on Apps, then Apps & features (or just Installed apps in Windows 11).
   4. You see a list of all installed programs. Scroll through this list. If you find a program you no longer use, click on its name, then click Uninstall. Follow any on-screen prompts.
3. Manage Large Files and Downloads:
   1. Open File Explorer by clicking its icon on the taskbar (it looks like a manila folder).
   2. Click on Downloads in the left sidebar. This is a common place where large files accumulate. Delete any downloaded installation files, old documents, or videos you no longer need by right-clicking them and selecting Delete.
   3. Remember to empty your Recycle Bin afterward: Go to your desktop, find the Recycle Bin icon, right-click it, and select Empty Recycle Bin.

Deleting files can feel daunting. If you are unsure about deleting a specific file or program, consider moving it to an external USB drive first, or asking for help from a trusted family member. You want to avoid deleting important system files.

For Apple Macs (macOS):

Macs have a helpful “Optimize Storage” feature.

   • Optimize Storage: This can automatically remove watched Apple TV movies and shows.
   • Empty Trash Automatically: This setting automatically empties your Trash after 30 days. You should turn this on.
   • Reduce Clutter: This option helps you find large files and documents you might want to delete. Click Review Files to explore.
6. To remove applications:
   1. Close the Storage Management window.
   2. Open Finder (the smiling face icon in your dock).
   3. In the sidebar, click on Applications.
   4. Find an application you no longer use. Drag (hold down the mouse button while moving the mouse) its icon to the Trash icon in your dock.
   5. Remember to empty your Trash afterward by right-clicking the Trash icon and selecting Empty Trash.

For Chromebooks (Chrome OS):

Chromebooks mostly store files online in Google Drive, so local storage is less of a concern. However, your Downloads folder (like a manila folder that holds your files) can fill up.

1. Open the Files app by clicking its icon on the shelf (it looks like a folder).
2. In the left sidebar, click on Downloads.
3. Review the files here. Many are likely temporary downloads.
4. To delete a file (a document, photo, or other item saved on your computer): Right-click on it and select Delete.
5. Files deleted from Downloads are permanently removed, they do not go to a Recycle Bin.
