Why Is My Computer So Slow?
First, let’s quickly understand why computers slow down:

- Full storage or a cluttered hard drive
- Outdated software
- Malware or bloatware
- Low RAM or aging hardware
- Startup overload
Now, let’s fix it.
Speed up For Windows Users
Disable Unnecessary Startup Programs
Many apps sneak into startup and slow down boot time.
- Steps:
PressCtrl + Shift + Esc
→ Go to Startup tab → Right-click & disable apps you don’t need at startup.
Uninstall Bloatware & Junk Software
Some programs run silently in the background.
- Steps:
Settings → Apps → Apps & Features or installed Apps → Uninstall apps you don’t use or recognize.
Clean Up Your Disk
Free up space using Disk Cleanup:

Start Menu → Search Disk Cleanup → Select Drive → Check unnecessary files (temp files, recycle bin, etc.) → Click Clean up system files.
Update Windows & Drivers
Outdated OS or drivers can cause lag.
- Steps:
Settings → Windows Update → Check for updates
Use Device Manager for driver updates.
Run a Virus/Malware Scan
Use Windows Defender or a trusted antivirus to remove hidden threats.
Upgrade RAM or Switch to SSD
If your PC is still slow after all this, consider:
- Upgrading from HDD to SSD
- Increasing your RAM to 8GB or more
Speed up For Mac Users
Check & Stop Resource-Hungry Apps
Use Activity Monitor to find what’s eating your CPU/RAM.

Applications → Utilities → Activity Monitor → Sort by CPU or Memory → Quit the high-usage apps.
Clean Up Your Storage

Apple Menu → About This Mac → Storage → Manage
