- Run the set - up utility to fix the date and time.

· Memory module incorrect configuration

- Users should refer to the user guide to ensure the memory needs

· Processor bus speed error

- We need to re-configure the correct processor

iv. Backup data retrieval

· Data retrieval procedure

· Data backup

v. Types of corrective action

· Interruptive action

· Non-interruptive action

vi. Types of restore

· Software restore

· Application restoration

· Data restore

· Configuration restore

vii. Computer system restoration :

· Types of software

- Software system

- Software language

- Software utility

· Types of data

- Data interface

- Ordinal data

- Radio data

· Restoration method

viii. Costing

· Computer part cost
