1. Remove Unnecessary Startup Programs
One of the most common reasons for a slow computer startup is having too many programs launching when your computer boots up. Many applications are configured to start automatically when you turn on your computer, running in the background and consuming valuable system resources.
Press Ctrl + Alt + Delete and select “Task Manager.” Click on the “Startup” tab to see all programs that launch at startup. Right-click on programs you don’t need to start automatically and select “Disable.”
Go to System Preferences > Users & Groups > Login Items. Select the applications you don’t want to start automatically and click the minus (-) button to remove them from the list.
By reducing the number of startup programs, your computer will boot faster and have more resources available for the applications you actually want to use.
Performance Impact
2. Uninstall Unused Programs and Bloatware
Over time, your computer accumulates programs that you no longer use. These unused applications take up valuable disk space and can sometimes run background processes that slow down your system.
Bloatware (pre-installed software that came with your computer) is often unnecessary and can be safely removed to free up resources. Here’s how to clean up your system:
Go to Settings > Apps > Apps & features. Sort the list by size to identify large programs. Select programs you no longer need and click “Uninstall.”
Open Finder > Applications. Drag unwanted applications to the Trash, or right-click and select “Move to Trash.” Then empty the Trash to completely remove them.
Be careful not to uninstall system applications or programs that your computer needs to function properly. If you’re unsure about a particular program, search for it online before removing it.
3. Clean Up Your Hard Drive
A cluttered hard drive can significantly slow down your computer. Temporary files, downloads, and other unnecessary data accumulate over time and can impact performance. Regular disk cleanup can help maintain optimal speed:
Type “Disk Cleanup” in the search bar and select the tool. Choose the drive you want to clean (usually C:) and select the types of files you want to delete. Click “OK” to proceed.
Go to Apple menu > About This Mac > Storage > Manage. Review the recommendations and use the tools to remove unnecessary files, empty the trash automatically, and store files in iCloud.
Additionally, you can use third-party cleaning tools like CCleaner (for Windows) or CleanMyMac (for Mac) to perform more thorough cleanups. These tools can help remove temporary files, browser caches, and other junk that standard cleanup tools might miss.
4. Defragment Your Hard Drive (HDD only)
If your computer uses a traditional hard disk drive (HDD), defragmenting can help improve performance. Over time, files on an HDD become fragmented, meaning parts of files are scattered across the disk, making it take longer for your computer to access them.
If your computer uses a solid-state drive (SSD), you should NOT defragment it. SSDs work differently from HDDs, and defragmentation can actually reduce the lifespan of an SSD.
Type “Defragment” in the search bar and select “Defragment and Optimize Drives.” Select your hard drive and click “Optimize.” Windows will analyze your drive and defragment it if necessary.
Mac OS X automatically defragments files, so manual defragmentation is generally unnecessary. However, if your Mac is very old and running slowly, you might consider using a third-party defragmentation tool designed for macOS.
5. Upgrade Your RAM
Random Access Memory (RAM) is your computer’s short-term memory. When you don’t have enough RAM, your computer has to use the hard drive as virtual memory, which is much slower. Adding more RAM is one of the most effective ways to speed up a slow computer.
Before purchasing new RAM, check how much RAM your computer currently has and the maximum amount it can support:
Right-click on “This PC” or “My Computer” and select “Properties.” Look for “Installed RAM” under the System section.
Click the Apple menu > About This Mac. Look for “Memory” to see how much RAM is installed.
If you’re not comfortable installing RAM yourself, consider bringing your computer to a professional service like Fix My Gadget. Our technicians can recommend the right type of RAM for your specific computer model and install it properly.
| RAM Upgrade | Performance Improvement | Ideal For |
|---|---|---|
| 4GB to 8GB | 30-50% | Basic multitasking, web browsing |
| 8GB to 16GB | 20-40% | Moderate multitasking, light gaming |
| 16GB to 32GB | 10-30% | Heavy multitasking, gaming, video editing |
6. Switch to a Solid-State Drive (SSD)
If your computer still uses a traditional hard disk drive (HDD), upgrading to a solid-state drive (SSD) can dramatically improve performance. SSDs have no moving parts and can read/write data much faster than HDDs, resulting in faster boot times, quicker file access, and overall improved system responsiveness.
While this upgrade requires some technical knowledge to transfer your operating system and files to the new drive, the performance improvement is substantial—often making even older computers feel like new.
You don’t need to replace your entire storage with an SSD. A common cost-effective approach is to use a smaller SSD (250-500GB) for your operating system and frequently used programs, while keeping your larger HDD for storing documents, photos, videos, and other files.

7. Update Your Operating System and Drivers
Keeping your operating system and drivers up to date is crucial for optimal performance. Updates often include performance improvements, bug fixes, and security patches that can help your computer run more efficiently.
Go to Settings > Update & Security > Windows Update and click “Check for updates.” Install any available updates. For drivers, use Device Manager to check for driver updates or visit your computer manufacturer’s website.
Go to Apple menu > System Preferences > Software Update. If updates are available, click “Update Now” or “Upgrade Now.”
8. Scan for Malware and Viruses
Malware and viruses can significantly slow down your computer by consuming system resources, displaying unwanted ads, or running malicious processes in the background. Regular security scans can help identify and remove these threats:
Use Windows Security (formerly Windows Defender) by going to Settings > Update & Security > Windows Security > Virus & threat protection. Click “Quick scan” to check for malware.
While Macs are generally less susceptible to viruses, they’re not immune. Consider using reputable security software like Malwarebytes for Mac to scan for potential threats.
In addition to built-in security tools, you might consider using reputable third-party antivirus software for more comprehensive protection.
9. Disable Visual Effects
Modern operating systems include various visual effects that look nice but can consume system resources. Disabling these effects can free up resources for more important tasks:
Type “Performance” in the search bar and select “Adjust the appearance and performance of Windows.” Select “Adjust for best performance” to disable all visual effects, or choose “Custom” to disable specific effects.
Go to System Preferences > Accessibility > Display. Check “Reduce motion” and “Reduce transparency” to minimize visual effects.
10. Manage Browser Extensions and Tabs
Web browsers can consume a significant amount of system resources, especially if you have multiple tabs open or numerous extensions installed. Managing these can help improve overall system performance:
- Limit open tabs: Each open tab consumes memory. Try to keep only necessary tabs open.
- Disable unused extensions: Browser extensions run in the background and can slow down your browsing experience. Disable or remove extensions you don’t regularly use.
- Clear browser cache: Regularly clearing your browser cache can help improve browsing speed.
Click the three dots in the top-right corner > More tools > Extensions. Toggle off or remove extensions you don’t need. To clear cache, go to Settings > Privacy and security > Clear browsing data.
Click the three lines in the top-right corner > Add-ons and themes > Extensions. Disable or remove unnecessary extensions. To clear cache, go to Options > Privacy & Security > Cookies and Site Data > Clear Data.
Go to Safari > Preferences > Extensions. Uncheck or uninstall extensions you don’t need. To clear cache, go to Safari > Preferences > Advanced > Show Develop menu in menu bar, then select Develop > Empty Caches.
