🚀 How to Speed Up a Slow Computer (2025)
Is your computer running slower than usual? Don’t worry —
you don’t always need to buy a new one. Sometimes, a few simple changes can
make your old PC feel fast again.
In this guide, we’ll show you 10 effective ways to speed
up a slow computer, step by step.
🔧 1. Uninstall Unused
Programs
Many computers slow down because of unnecessary software
running in the background.
Go to:
Control Panel → Programs → Uninstall a Program
Remove any software you don’t use.
🚫 2. Disable Startup
Programs
Too many apps starting with Windows can cause delays.
Steps:

+ Shift + Esc to open Task Manager

the Startup tab

and Disable unwanted programs
🧹 3. Clean Temporary and
Junk Files

temporary files, system cache, and Recycle Bin

to clean
💉 4. Scan for Viruses and
Malware
Malware can secretly slow down your system.
Use tools like Windows Defender, Malwarebytes, or any trusted
antivirus to scan and remove threats.
🧠 5. Add More RAM (if
possible)
If your computer struggles when you open many tabs or
programs, your RAM might be low. Adding more RAM can boost performance,
especially on older PCs.
⚙️ 6. Switch to SSD
If your computer still uses an HDD, upgrading to a Solid
State Drive (SSD) can make a huge difference in boot time and speed.
🔄 7. Restart Regularly
Yes, it sounds basic — but a simple restart can clear
memory leaks, stop background processes, and refresh your system.
🧱 8. Update Windows and
Drivers
Old drivers and outdated systems can slow your PC.
Steps:
- Go to Settings
→ Windows Update
- Check
for updates
- Also
update your display, audio, and network drivers
🧰 9. Reduce Visual
Effects
Fancy animations take up memory.
Steps:
- Right-click
This PC → Properties
- Click Advanced
system settings → Settings under Performance
- Select
“Adjust for best performance”
🗂️ 10. Defragment Your
Hard Drive (HDD only)
If you use an HDD, defragmenting can help:

“Defragment” in the Start menu
- Select
your drive
- Click Optimize
✅ Final Tip:
If your system is still slow after trying everything, it
might be time for a fresh Windows installation or a hardware upgrade.
