If checking external and internal connections does not fix the problem, consider 
inspecting the system component by component (see Table A) and verifying that each 
hardware component is properly installed and configured before you decide to replace 
costly components. 

If a component in the system you are servicing does not meet a condition listed in 
Table A, and it is not clear how to fix the problem (for example, if the system hangs 
before reaching Idle), locate the behavior in Table B on page 73 to see the suggested 
action(s) for solving the problem.
