Speed up your slow PC quickly and easily
Is your PC or laptop running painfully slow?
Freezing, lagging, taking forever to open apps?
Good news — most slow computers can be fixed with a few easy steps. ⚡
This 2026-friendly guide shows you exactly how to speed up your system, even if you’re not tech-savvy.
1. Restart Your Computer 🔄
It sounds basic, but restarting clears:
- cached processes
- stuck apps
- memory leaks
A quick restart often gives instant performance improvement.
2. Close Background Apps Using Task Manager 🧹
Many apps run silently and eat resources.
- Press Ctrl + Shift + Esc
- Open Task Manager
- Sort by CPU or Memory
- Close anything heavy you’re not using
Common offenders:
- Chrome
- Steam
- Discord
- Adobe apps
- AI tools
3. Disable Startup Apps ⚙️
If your computer is slow when booting, this is the fix.
Go to:
Task Manager → Startup apps → Disable high-impact apps
==This alone can reduce your startup time from minutes to seconds.==
4. Free Up Storage Space (Aim for 20GB+) 🗃️
Low storage = slow system.
Quick cleanup steps:
- Empty Recycle Bin
- Delete temp files
- Uninstall unused programs
- Clear browser caches
- Move videos/photos to cloud
💡 Pro Tip:
Enable Storage Sense in Windows to auto-delete junk files.
5. Run a Full Malware Scan 🛡️
If your computer slowed down suddenly, malware or adware may be the cause.
Use built-in tools:
- Open Windows Security
- Select Virus & threat protection
- Run a Full scan
Windows Defender is more than enough for most threats in 2026.
6. Stop Overheating Issues 🌡️
Heat slows your system to protect hardware.
Fixes:
- Clean dust from vents
- Use a cooling pad
- Avoid using your laptop on a bed/blanket
- Close heavy apps while charging
Overheating = automatic performance drop.
7. Switch to an SSD (If You Still Have an HDD) ⚡
If you're still on an older spinning hard drive:
Upgrading to an SSD = the biggest speed boost possible.
Benefits:
- faster boot
- faster loading
- less freezing
- better multitasking
Even cheap SSDs make old computers feel new.
8. Add More RAM (Memory) 💾
Recommended RAM amounts in 2026:
- 8GB: minimum
- 16GB: ideal for most users
- 32GB+: gaming or creative apps
More RAM improves multitasking and reduces lag dramatically.
9. Update Windows & Drivers 🔧
Outdated systems = slower systems.
Update Windows:
Settings → Windows Update → Check for updates
Update GPU drivers:
- NVIDIA
- AMD
- Intel
These updates often include performance optimizations.
10. Reset Your Browser 🌐
If websites lag or crash, your browser might be bloated.
Try:
- resetting browser settings
- disabling unused extensions
- clearing cached data
Chrome, Edge, and Firefox can all slow down your entire system when overloaded.
11. Use Windows Reset as a Last Resort ♻️
If everything still feels sluggish:
Windows Reset gives you a fresh OS without deleting personal files.
Go to:
Settings → System → Recovery → Reset this PC
Choose:
Keep my files
Conclusion
Slow PC or laptop performance is almost always fixable.
Start with simple steps like restarting, closing heavy apps, and cleaning up storage.
Then move to deeper fixes like malware scans, overheating checks, and hardware upgrades.
With the right tweaks, your computer can run like new again — even in 2026. 💻⚡
