8 Troubleshooting Steps

Step 1

How often does this happen?:- This question establishes whether this problem is a one-time occurrence(usually indicating a soft memory error or the like) that can be solved with a reboot, or whether a specific sequence of events causes the problem to happen(usually indicating a more serious problem that may require software installation or hardware replacement.H

Has any new software been installed recently?:- New software can mean incompatibility problems with existing programs.This is especially true for Windows programs.A new Windows program can overwrite a required DLL file with a newer version of the same name,which an older program may not find useful.Windows XP now has a feature called RESTORE POINTs. Each time Windows XP boots successfully, it notes its configuration. If you install new software and it overwrites a DLL, causing ,major functionality problems,you can reboot in safe mode back to the last logged restore point and roll back the configuration to when the computer last worked properly.

Have any other changes been made to the computer recently?:- If the changes made then try to remember approximately when the change was made. Then try to remember approximately when the problem started. If the two dates seem related, there’s a good chance the problem is related to the change,If the change involved a new hardware component,check to see that the hardware component was installed correctly.

Step 2

this step is the one that most experienced technicians overlook.Often,computer problems are the result of something simple.Technicians overlook these problems because they’re so simple that the technicians assume they couldn’t be the problem.Some examples of the simple problems are shown here:

Is it plugged in?:- And plugged in on both ends? Cables must be plugged in on both ends in order to funtion correctly.Cables can be easily tripped over and inadvertently plugged from their sockets.

Is the system ready?:- Computers must be ready before they can be used, Ready means the system is ready to accept commands from the user. An indication that a computer is ready is when the operating system screens come up and the computer presents you with a menu or a command prompt.If that computer uses a graphical interface, the computer is ready when the mouse pointer appears.printers are ready when the Online or Ready light on the front panel is lit.

Reseat chips and cables:- You can solve some of the strangest problems (random hang-ups or errors) by opening the case and pressing down on each socketed chip. You should also reseat any cables to make sure that they are making good contact.

Other Notes:- Do you know how to reboot the windwos server with command ?.
Answer :- go to command prompt

Press–>Enter ( system will start rebooting )

type–>shutdown -r -f

-r switch for reboot the machine and -f for forcely.

 

Step 3

It is amazing how often a simple computer reboot can solve a problem.Rebooting the computer clears the memory and starts the computer with a clean state.Whenever I perform phone support, I always advice the people to reboot the computer and try again.If rebooting doesn’twork,try powering down the system completely,and then powering it up again.More often than not,that will solve the problem.

 

Step 4

This step is important because it determines what part of the computer you should focus your troubleshooting skills on.Each part requires different skills and different tools.
To determine if a problem is hardware or software related,you can do a few things to narrow down the issue.For instance,does the problem manifest itself when you use a particular piece of hardware(a modem, for example)? If it does, the problem is more than likely hardware related.
This step relies on personal experience more than any of the other steps do.you will without a doubt run into strange software problems.Each one has a particular solution.Some may even require reinstallation of the software or the entire operating system.

 

Step 5

Hardware problems are pretty easy to figure out.If the modem doesn’t work,and you know it isn’t a software problem,the modem is probably the piece of hardware that needs to be replaced.
With some of the newer computers,several components are integrated onto the motherboard.If you troubleshoot the computer and find a hardware component to be bad,there’s a good chance that the bad component is integrated into motherboard(for example,parallel port circuitry)and the whole motherboard must be replaced-an expansive proposition, to be sure.

 

Step 6

If you are experiencing software problems,a common troubleshooting technique with DOS-based computers is to boot clean.This means starting the computer with a bootable diskette that uses a CONFIG.SYS and AUTOEXEC.BAT with no third-party drivers(for example,no drivers for sound card, CD-ROM,or network). If the software that’s experiencing the problem is incompatible with something is these clean CONFIG.SYS and AUTOEXEC.BAT files,this will indicate the problem.Once you have determined that there’s an incompatibility,you can further determine what your chances are for fixing the problem by using the REM techniques.Restarting the computer in Safe mode is a clean boot for Windows 9X and Windows 2000.Only Windows default drivers will be loaded.

 

Step 7

As you may have figure out by now. I’m fond of old saying.There’s another one that applies here: ” If all else fails,read the instructions “.The service manuals are your instructions for troubleshooting and service information.Almost every computer and peripheral made today has a set of service documentation in the form of books,service CD-ROMs and websites.The latter of the three is growing in popularity as more service centers get connections to the Internet.

 

Step 8

When doctors take the Hippocratic oath,they promise to not make their patients any sicker than they already were.Technicians should take a similar oath.It all boils down to, ” If it ain’t broke donot fix it “.When you troubleshoot, make one change at a time.If the change doesn’t solve the problem,change the computer back to its original state before making a different change.
