A slow, freezing laptop is frustrating but usually fixable. Here’s a comprehensive guide to restoring your laptop’s performance.
Why Laptops Slow Down

Quick Diagnostic
Check Resource Usage
- Press Ctrl + Shift + Esc

- Identify what’s maxed out:
- 100% Disk = storage issue
- 100% CPU = processing issue
- High Memory = RAM shortage
Check Temperatures
- Download HWiNFO
- Monitor CPU temperature
- If over 85°C during normal use = overheating
