Step-by-step

A computer health check, step by step

The order of work for a routine maintenance visit.

  1. Agree and protect

    Get the owner's permission, ask about problems and confirm a recent backup exists — make one if not.

  2. Measure before

    Record start-up time, free disk space, pending updates, drive health and any error messages.

  3. Clean and inspect

    Shut down, unplug and clean vents and fans; check cables, battery and ports.

  4. Update and tidy

    Install updates and drivers, remove unwanted software with the owner's agreement and reduce start-up apps.

  5. Check security

    Confirm protection, firewall and encryption are on and the user has a standard account.

  6. Measure after and report

    Record the same measures again and write the service report with recommendations.

Result

A faster, safer computer and a report that shows the owner exactly what changed and what to do next.
