A slow computer can be frustrating — whether you’re working, gaming, or just browsing the internet. Over time, dust, outdated software, and unnecessary background processes can make even a powerful system feel sluggish.
Here are practical tips to boost your computer’s speed and performance.


1️⃣ Restart Your Computer Regularly

Many users keep their computers running for days or weeks without restarting. Restarting helps:

  • Clear temporary files
  • Refresh system memory
  • Stop background apps that slow performance

Tip: Restart your computer at least once every 2–3 days.


2️⃣Use Best Performance Mode

Your computer’s power plan affects speed. If it’s set to Power Saver or Balanced, it may limit CPU performance to save battery. Switching to Best Performance Mode ensures your hardware runs at full speed.

Windows 10 / 11:

  1. Right-click the Battery icon in the taskbar → Power & sleep settings
  2. Click Additional power settings
  3. Select High performance or Ultimate performance (if available)

Quick Method:

  • Press Windows + X → Power Options
  • Under Related settings, choose Additional power settings and switch to High performance

For Laptops:

  • Keep the charger plugged in for heavy work or gaming
  • Avoid Battery Saver Mode — it slows down CPU and GPU

Mac:

  1. Go to System Settings → Battery
  2. Set Energy Mode to High Power (on supported MacBooks)

3️⃣ Keep Your System Cool (Very Important!)

Overheating is one of the biggest hidden causes of slow computers. When your CPU or GPU gets too hot, it automatically reduces speed to prevent damage — this is called thermal throttling.

Tips to Maintain Proper Cooling:

  • Avoid using laptops on beds, pillows, or blankets – these block air vents and trap heat.
  • Place your laptop on a flat, hard surface so the air can flow freely.
  • Slightly raise the back of the laptop using a stand, books, or a cooling pad — this improves airflow underneath.
  • Clean dust from fans and vents every few months using compressed air.
  • For desktops, make sure the case fans are working properly and that cables inside are not blocking airflow.

Why it matters:
Even the fastest computer will slow down if it overheats, so keeping it cool directly improves speed and extends hardware life.


4️⃣Disable Startup Programs

Too many apps launching at startup can slow down boot time.

Windows:

  1. Press Ctrl + Shift + Esc to open Task Manager
  2. Go to Startup tab
  3. Disable programs you don’t need to launch automatically

Mac:

  1. Open System PreferencesUsers & Groups
  2. Select your profile
  3. Remove unnecessary login items

5️⃣ Uninstall Unused Software

Unused applications take up storage space and may run hidden background services.

Steps:

  • On Windows: Go to Control Panel → Programs → Uninstall a program
  • On Mac: Drag apps to Trash and empty it

6️⃣Clean Temporary Files

Over time, your system accumulates cache, logs, and temporary files that slow it down.

Windows:

  • Press Windows + R, type %temp% → delete all files
  • Use tools like Disk Cleanup or CCleaner

Mac:

  • Use Finder → Go → Go to Folder → ~/Library/Caches and delete unnecessary files

7️⃣ Increase RAM

If your computer struggles when multiple programs are open, you may need more memory.

  • Check system requirements for the software you use
  • Upgrade RAM if possible — it’s one of the best performance boosts


8️⃣ Advanced Tip – Reinstall OS

If nothing works, a fresh install of Windows or macOS can restore peak performance.


💡 Final Thoughts

A slow computer doesn’t always mean you need to buy a new one.
With the above steps, you can often restore speed and extend your system’s life.
