Software Diagnostics Routines

Many disk based diagnostic methods can check the system and identify the problems by running the number of tests on the different areas of the system hardware. These tests produce the visual reports and error messages to identify the nature of the problem. The most common software troubleshooting routines check the computer’s memory, keyboard, monitor, system processor, and hard disk’s speed. If the system CPU, hard disk and system clock is working properly, then you will be able to localize the problem by targeting the other points in the system. If the diagnostic tools/routines identify a number of defective software/hardware then you should replace one defective unit a time.
