Step-by-Step Troubleshooting Framework
Before diving into specific problems, it’s essential to understand the universal process professionals use when tackling tech issues.
Identify the Problem
Ask:
- What exactly is not working?

Restart the Device
The classic solution. Rebooting can clear cache, reload services, and fix memory leaks.
Use Built-In Tools
Run:
- Windows Troubleshooter
- macOS Disk Utility
- Smartphone Safe Mode
- Antivirus scans
Search for Solutions
Use trusted forums like:
- Microsoft Support
- Apple Discussions
- Reddit’s r/techsupport
- Stack Overflow (for developers)
Test and Apply Fixes
Apply one fix at a time so you can identify what worked.
Document the Solution
For recurring issues or future reference, take note of what worked and why.
