Identify the problem and its exact symptoms
Check for obvious causes (power, connections, settings, error messages)
Restart the device/system/application
Verify updates are installed
Reboot the router/modem if it’s a network issue
Check cables, ports, and power sources
Reseat connections and replace faulty cables if needed
Clear cache and temporary files (browser/app/system)
Remove recently added software or changes
Run built-in diagnostics or troubleshooters
Reset relevant settings to defaults
Check permissions/access rights (accounts, roles, security settings)
Scan for malware and run antivirus checks
Free up storage space if performance or installation fails
Repair or reinstall the affected app/software
Update drivers (GPU, network, chipset)
Roll back recent driver/OS updates if the issue started after them
Check logs/event viewer for specific error codes
Test in a different browser/device/network to isolate the cause
Restore from a backup or system restore point if available
Contact support with the error details, logs, and steps already tried
If hardware-related, replace the failing component (drive, RAM, PSU, etc.)
