If your computer is running slow but you’re not ready to upgrade its hardware, there are several ways to boost performance without spending money on new components. By optimizing your software, settings, and maintenance routines, you can make your PC run faster, smoother, and more efficiently.
This guide covers the best methods to improve your computer’s performance without upgrading its parts.
1. Restart Your Computer Regularly
Many users leave their computers on for days or even weeks, leading to slow performance due to memory leaks and background processes. Restarting your computer clears temporary files, refreshes system resources, and closes unnecessary applications.
✅ Solution: Restart your PC at least once every few days to keep it running efficiently.
2. Free Up Storage Space
A nearly full hard drive or SSD slows down your system by reducing available space for temporary files and caching.
✅ How to Free Up Disk Space:
✔ Delete unnecessary files – Use Storage Sense (Windows) or Disk Cleanup.
✔ Uninstall unused programs – Go to Control Panel > Programs > Uninstall a Program.
✔ Clear browser cache and temporary files – Use CCleaner or built-in browser tools.
✔ Move large files to an external drive – Offload photos, videos, and backups.
✔ Aim to keep at least 20% of your storage free for smooth operation.
3. Disable Startup Programs
Many applications launch at startup, consuming RAM and CPU power even when not in use.
✅ How to Disable Startup Programs (Windows 10/11):
1️⃣ Press Ctrl + Shift + Esc to open Task Manager.
2️⃣ Go to the Startup tab.
3️⃣ Disable unnecessary programs by right-clicking and selecting Disable.
Disabling non-essential startup apps like Spotify, Skype, and Adobe services can improve boot time and system speed.
4. Optimize Your RAM Usage
If your computer feels sluggish, it may be running out of RAM.
✅ How to Free Up RAM:
✔ Close unused applications running in the background.
✔ Use lightweight alternatives – Try Microsoft Edge instead of Google Chrome (which uses more RAM).
✔ Disable unnecessary animations – Go to System > Advanced Settings > Performance Options and select Adjust for Best Performance.
If you frequently run out of RAM, consider using a lighter operating system or disabling background applications.
5. Scan for Malware and Viruses
Malware and viruses can slow down your system by consuming resources in the background.
✅ Best Free Antivirus & Malware Removal Tools:
✔ Windows Defender – Built-in and effective for most threats.
✔ Malwarebytes – Great for scanning and removing unwanted software.
✔ Avast or Bitdefender – Free antivirus with real-time protection.
Run weekly scans to keep your system free of harmful software.
6. Update Your Operating System and Drivers
Outdated software can cause slowdowns, crashes, and security issues. Keeping your system updated ensures better stability and performance.
✅ How to Update Windows & Drivers:
✔ Windows Update: Go to Settings > Update & Security > Windows Update and check for updates.
✔ Driver Updates: Visit the official websites of your GPU, motherboard, and peripherals to download the latest drivers.
✔ Use Manufacturer Software: NVIDIA’s GeForce Experience or AMD’s Adrenalin Software can help keep your graphics drivers up to date.
Updating your OS and drivers can resolve many slowdowns and compatibility issues.
7. Adjust Power Settings for Maximum Performance
By default, Windows may run in balanced or power-saving mode, which limits performance to save energy.
✅ How to Enable Maximum Performance Mode (Windows 10/11):
1️⃣ Open Control Panel > Power Options.
2️⃣ Select High Performance or Ultimate Performance (if available).
⚠ Note: This will use more power but boosts CPU and GPU performance.
8. Clean Your Computer for Better Cooling
Overheating can slow down your PC due to thermal throttling, where the CPU or GPU reduces speed to prevent damage.
✅ How to Improve Cooling:
✔ Clean dust from vents and fans using compressed air.
✔ Ensure good airflow by placing your PC in a well-ventilated area.
✔ Check CPU & GPU temperatures using HWMonitor or MSI Afterburner.
✅ Safe Temperature Ranges:
✔ CPU under load: 50–80°C (above 90°C is dangerous).
✔ GPU under load: 60–85°C (above 90°C is risky).
Lower temperatures help maintain optimal system performance.
9. Optimize Your Hard Drive or SSD
Over time, storage drives become fragmented and slow down.
✅ How to Optimize Your Drive:
✔ For HDDs: Use Defragment and Optimize Drives (Windows).
✔ For SSDs: Run TRIM (automatically managed by Windows 10/11).
⚠ Note: NEVER defragment an SSD – it reduces lifespan without improving speed.
10. Use Lightweight Software Alternatives
Some applications consume a lot of system resources. Replacing them with lighter alternatives can improve performance.
✅ Best Lightweight Software Replacements:
✔ Web Browser: Use Microsoft Edge instead of Google Chrome.
✔ Office Suite: Use LibreOffice instead of Microsoft Office.
✔ Media Player: Use VLC Media Player instead of Windows Media Player.
Choosing optimized software reduces RAM and CPU usage, improving overall speed.
11. Manage Virtual Memory (Pagefile Size)
If your system runs low on RAM, Windows uses a portion of your hard drive as virtual memory (pagefile). Adjusting this setting can improve performance.
✅ How to Adjust Virtual Memory in Windows:
1️⃣ Go to Control Panel > System > Advanced System Settings.
2️⃣ Under Performance, click Settings > Advanced.
3️⃣ Under Virtual Memory, click Change.
4️⃣ Set the Initial size and Maximum size (recommended: 1.5x your RAM size).
This helps if your PC has low RAM but plenty of storage space.
12. Disable Background Apps and Services
Many apps run in the background, consuming system resources.
✅ How to Disable Background Apps (Windows 10/11):
1️⃣ Go to Settings > Apps > Background Apps.
2️⃣ Disable unnecessary apps from running in the background.
This frees up CPU and RAM, making your system faster.
13. Restart Windows Explorer for Instant Speed Boost
If your PC becomes slow and unresponsive, restarting Windows Explorer can refresh the system.
✅ Steps to Restart Windows Explorer:
1️⃣ Press Ctrl + Shift + Esc to open Task Manager.
2️⃣ Find Windows Explorer in the list.
3️⃣ Right-click and select Restart.
This refreshes the UI and improves responsiveness without restarting the whole PC.
