PC Running Slow? 10 Easy Ways to Speed Up Your Computer Fast

Is your PC running slow lately? Long boot times, lag when opening apps, freezing during work, or slow browser performance? You’re not alone. Millions of Windows users experience performance issues over time.

The good news? You don’t necessarily need to buy a new computer. In many cases, you can fix a slow PC with simple optimization steps.

In this guide, we’ll cover 10 proven ways to speed up your Windows PC, whether you’re using Windows 10 or Windows 11.

Why Is My PC So Slow?

Before jumping into solutions, it’s important to understand common causes of a slow computer:

• Too many startup programs
• Low storage space
• Malware or viruses
• Outdated drivers
• Insufficient RAM
• Old or slow hard drive

Identifying the root cause helps you choose the right fix.

1. Disable Unnecessary Startup Programs

Many applications automatically launch when Windows starts. This significantly slows boot time.

How to disable startup apps:

1. Press Ctrl + Shift + Esc
2. Open the Startup tab
3. Right-click unwanted programs
4. Select Disable

Reducing startup programs is one of the fastest ways to speed up your PC.

2. Free Up Disk Space

When your hard drive is nearly full, your PC performance drops.

Quick cleanup steps:

• Open Settings → System → Storage
• Enable Storage Sense
• Delete temporary files
• Empty the Recycle Bin

Keep at least 15–20% of your drive free for optimal performance.

3. Uninstall Unused Programs

Old software can consume storage and system resources.

Go to: Settings → Apps → Installed Apps and remove programs you no longer use.

4. Scan for Malware and Viruses

Malware is a major cause of slow computers. Run a full system scan regularly using:

• Windows Security (built-in protection)
• A trusted antivirus program

A secure system performs better and stays stable.

5. Update Windows and Drivers

Updates often include performance improvements and bug fixes.

Go to: Settings → Windows Update → Check for updates

Also update graphics, chipset, and network drivers for best results.

6. Upgrade to an SSD (Biggest Performance Boost)

If you’re still using an HDD, upgrading to an SSD can dramatically improve speed.

• Faster boot times
• Quick application loading
• Better system responsiveness

Switching to an SSD can make an old PC feel brand new.

7. Add More RAM

If your computer slows down during multitasking, you may need more memory.

• 8GB minimum for everyday use
• 16GB recommended for gaming or heavy tasks

More RAM allows smoother performance across multiple applications.

8. Adjust Visual Effects for Better Performance

Windows animations use system resources.

1. Right-click This PC
2. Select Properties
3. Click Advanced system settings
4. Under Performance, click Settings
5. Select Adjust for best performance

9. Keep Your PC Cool

Overheating reduces performance. Make sure to:

• Clean dust from fans
• Ensure proper airflow
• Use a cooling pad for laptops

A cooler PC runs faster and lasts longer.

10. Reset or Reinstall Windows (Last Resort)

If nothing works, resetting Windows can fix deeper system issues.

Go to: Settings → System → Recovery → Reset this PC

Important: Back up your files before proceeding.

Bonus Tips to Keep Your PC Fast

• Limit browser extensions
• Avoid unnecessary software installations
• Use lightweight applications
