Preliminary 8-2002 RSHD Smartcaster Installation Manual

Don't get locked into a narrow-minded approach or solution that you are sure is "IT". All

too often, it isn't and when you have locked yourself into that solution, you make it much

more difficult to correctly identify the problem. To stick with the example of the monitor

not working, don't assume it must be the monitor and just focus on the monitor. The

monitor could be working just fine, but it does not receive a signal from the video card

because the video card was not seated correctly and slipped out of its slot. Or to use our

earlier example with the computer not booting, don't limit your troubleshooting to the

computer. Maybe the problem was that the outlet it is plugged into, is controlled by a

switch that accidentally got flipped to the Off position. Be sure to look at the whole

picture.

Think about what a computer really does. Never forget that all a computer really does is

manipulate 1s and 0s. It uses a number of mechanical devices and software to let it do

this and to communicate that information with you. When you have a problem with the

computer, the problem has to do with its ability to manipulate that information.

What are the key processes that need to be considered?

Electricity - A computer requires a clean, uninterrupted source of electricity to operate.

Not having that will cause problems sooner or later.

Processor - This is where the code is actually manipulated and it must work properly for

the computer to work properly. Fortunately, the processor chip is one of the most reliable

parts of the computer when run at its recommended settings.

Memory - SDRAM, RDRAM, or whatever memory you have must work well or there

will be errors. This is where the computer stores the data it is manipulating.

Storage - You have to keep the information somewhere. That is usually the hard drive. If

the hard drive is having problems, then you can expect to have problems.

Along with all those things are the motherboard and the various peripherals that link it all

together and allow us to see and hear the data or share the data with other computers.

Remember that each of these devices has specific functions, but the four mentioned

above effect everything we do with the computer. If the problem is a system-wide one,

then we should take a hard look at these four devices.
