INFORMATION SHEET 1.1

CONCEPT OF DIAGNOSING AND TROUBLESHOOTING COMPUTER SYSTEM

Learning Objectives: After reading this information you must be able to acquire knowledge in

reading skills required to interpret work instruction.

1. DISASSEMBLY

Leaving the computer plugged in is a recommended procedure. However, make sure it'sswitched off and remember that the cable going to the remote switch on the front of the

case carries AC current at house voltage. Also, ATX motherboards have power to them

all the time, even when the switch is off. Before beginning to remove a power supply or




If possible, enter the CMOS setup and record the information available. At least record

the floppy and hard drive configuration and any settings that may be different from the

default. You want to be careful not to remove the battery and lose these settings, butstuff happens.

Disassembly is major surgery, do a full backup of the system. Programs that you havethe original disks for can always be replaced, but any upgrades for those programs and

any programs that have been downloaded from the Internet may or may not still beavailable. Bookmarks, e-mail addresses, phone and fax numbers, dial-up connections,

DNS settings and networking protocols can be a real pain to replace. Even the best

technicians cannot guarantee your data, so back it up. Also, in Windows9x, all the IRQ,I/O addresses, and DMA settings can be found (and printed) from the Device Manager

in Control Panel. In Windows98 check out Start/Programs/Accessories/System

Tools/System Information.

Close all programs, shut down Windows, and turn off your computer. Then remove the

cables from the back of the case.

2. DIAGNOSING FAULTS AND FAILURE OF THE COMPUTER SYSTEM




3. RE-ASSEMBLY

* After you have already fixed all the faults that has been diagnosed, you have just to put

all the necessary thing to make the computer back to its original looks.- make sure that all the peripherals in the system unit are placed in their respective slot

like:

a. Memory b. Video Card (if not on-board)

c. Sound Card (if not on-board)

d. Land Card (if not on-board)e. Hard Disk

f. Power Supplyg. CD Rom

h. Floppy Disk




4. TEST-RUNNING THE COMPUTER

* Open the computer system and then test the entire program you have installed in the computer

and make sure that it is in good running condition.

INFORMATION 1.2

DIAGNOSE FAULTS OF COMPUTER SYSTEMS

Learning Objectives: After reading this information you must be able to acquire knowledge inreading skills required to interpret work instruction.

Guide to Computer Troubleshooting and Repair - PC Troubleshooting Manual

PC's are actually much easier to repair these days than in the early 90's when I wrote the my old

guide for technicians I was training. The number of discrete parts in a PC has dropped radicallysince I first cracked open an PC AT in 1985. The average PC these days has less than a dozen

parts, unless you start counting cables, and that total includes the keyboard and mouse! So, some

new techs figure the way to learn computer repair and hardware troubleshooting is to carry

around a few spare parts and swap-til-you-drop. Well, it doesn't really work that way for anumber of reasons, including the fact that all the really tough problems are intermittent, so

diagnosing the problem correctly is actually the main challenge. Computer hardware problems

are less common than software problems (just think about all the malware and viri running about

the Internet), and there are far fewer variables to consider when learning to troubleshoot PChardware. The real trick is to go about it in a systematic matter, eliminating possibilities

whenever possible before you start purchasing replacement parts. To that end, I developed aseries of diagnostic flowcharts for logical approach to computer repair. Four miniature flowcharts

are below, the full size versions are accessed by clicking on the images or the links. All of the

flowcharts are excerpted from the published book "Computer Repair with Diagnostic

Flowcharts" which is also used as a technicians field manual and a course text in technicalcolleges.

Power Supply Troubleshooting The first place

to start is always confirming that the power

supply is operating properly. When you start

Video Failure Troubleshooting When we talk

about troubleshooting video failures, we'reusually talking about no image at all on the

screen. The easy cases to diagnose are thosewhere the monitor or LCD isn't powering up

Motherboard and CPU Troubleshooting There are very few instances when you'd turnon a PC, have it either power up or not, and be

able to say, "Oh, that's a motherboard

Hard Drive Failure TroubleshootingStudents who are still learning the basics of

computer repair, like what components are

involved in what operation, will frequentlyassume that all boot issues are due to a hard

drive failure. The truth is, of all the four

b d i hi bl h d

http://www.fonerbooks.com/cpu_ram.htm


http://www.fonerbooks.com/ide_hd.htm












The computer locks up and/or is acting weird?

1. If the computer is frozen and will not respond to any commands, it may be necessary to press Ctrl +Alt + Del (all three keys at the same time) to bring up the Task List. Select any program that says "Not

responding" and click the End Task button. Repeat until all tasks are ended. If this does not work, turnthe computer off, wait several seconds, turn the computer back on, and let the computer run theScandisk.

2. Reboot it. A majority of problems that occur while you are using your computer can be fixed by

rebooting. Applications sometimes don’t release memory like they should when they are finished. The

end result is your computer locks up or acts really weird. When you reboot, memory registers are

cleared and most everything is reset. This fixes a lot of problems.

Special Note

It doesn't hurt a computer to leave it running all the time. However, using the computer for long periods

of time causes small problems that can build into larger ones. When Windows reboots, it fixes most of

these small problems. Therefore, restarting the computer periodically while working can help reduce therisk of glitches.

Back to Top

the computer is completely dead?

Check all the connections, the cables between the CPU and the monitor and all the electrical cables.

Check the wall socket or surge strip to see if they are bad (sometimes a surge strip will have good and

bad outlets). If you have a green light on your monitor but not on your CPU, then there is a problemwith your CPU. If there is a green light on your CPU and not your monitor, then you have a problemwith your monitor and your CPU may be fine. If you have another monitor that you know is good, the

quickest way to test is to put another monitor on the machine and see if you get an image on the screen.

2. Check to make sure the keyboard is still properly connected to the computer. If the keyboard

has been disconnected, you may have to reboot your computer.

3. If all else fails, then turn the power off. Wait a couple of minutes before turning the computer back

on.

Special Note

One of the dirtiest parts of your computer is the keyboard. Regular cleaning will help keep the keyboard

working properly. First, blow compressed air through the spaces in between the keys to remove dust

and lint. If you shake your keyboard upside-down this will also remove some of the particles.

Another keyboard problem that could occur is when you turn your computer on and you get a message

that no keyboard was detected or you get into Windows but are not able to type. Remove the keyboard

connector for the CPU, examine the pins in the connector to ensure they are straight, then reinsert theconnector. Also, check and make sure the mouse and keyboard connectors have not been switched. If

the keyboard still doesn’t work try connecting, another keyboard that you know is working. This will

determine if you need a new keyboard or if you have a CPU problem.

Back to Top

the mouse doesn't work?

Check to make sure the mouse is still properly connected to the computer. If the mouse has beendisconnected, you may have to reboot your computer.

Like the keyboard, the mouse pad is sitting in the open most of the time getting dusty, wet, slimed, or

anything else that happens on you desktop. The mouse then rolls over whatever has collected on the

mouse pad and gets inside, gumming up the works. To clean the mouse pad, wipe it off occasionally






the computer displays a disk error or non-system disk message?

1. You may have left a disk in the A drive. Remove it and press any key on the keyboard to reboot thecomputer.

2. If you don’t have a disk in the A drive, and the message is accompanied by a "clunking" sound, turn

the computer off and send for a technician.

Back to Top

the computer starts up in "safe mode"?

At times your computer could develop a problem which causes you machine to boot up in what is called"safe mode". The easiest way to try and solve this problem is to run a "scandisk".

1. Click on Start, Programs, Accessories, System Tools, and Scandisk .

2. Place a check on "Automatically fix errors".

3. When Scandisk finishes, reboot your computer to see if this fixed the problem.

4. If the computer still boots up in the Safe Mode, click on Start, Programs, Accessories, System

Tools, and Disk Defragmenter. If you receive the message "You don't need to defragment this drivenow", continue with the process anyway.

5. When Disk Defragmenter is finished, reboot your computer to see if this fixed the problem.

6. If the computer still starts up in safe mode, you need to contact a computer technician.

2. If the printer self test prints, the next step is to have Windows print a test page. Click on Start,

Settings, Printers, and right click on the icon of the printer with the problem. Select properties and

press the Print Test Page button. If the test page fails to print, make sure the printer cable is firmlyseated in both the computer and the printer. You should also check the ends of the printer cable to make

sure that none of the prongs are bent. If the test print fails, or if the print consists of nonsense charactersor a few characters printed over many pages, you need to uninstall then reinstall the drivers for your

printer.

Paper feed problems and jams can often be resolved by using paper which conforms with thespecifications provided by the printer manufacturer. On ink jet printers, the rubber rolls which pick up

each sheet can sometimes become coated with paper residue which decreases the friction. Cleaning off

the residue can sometimes solve paper feed problems.

Special Note

If your ink jet printer is making a banging or grating noise, you need to clean two areas of the printer.

1. Some models of ink jet printers have a gray colored narrow plastic film which extends almost thewhole width of the printer just behind the rod on which the print head travels. If this film gets dirty, the

print heads can have problems determining where it is and can crash against the end of the printer. Usetissue or soft cloth to clean this strip.

2. The printer head moves across a rod that can also become dirty. With the printer power on, raise the

front of the printer and clean the rod with a paper towel. Put the front of the printer back down and turnoff the printer. This time when you lift the front of the printer, the printer heads will move across the

rod. This will allow you to clean the part of the rod that was covered when you cleaned it the first time.

If you spray the paper towel with WD-40, this will do a better job of cleaning the rod.

As the printer gets older, it may become necessary to perform these two cleaning jobs at least once

a week.

You want to make sure you have what you need. Your wrist strap is attached to the

computer you don't want to have to run to the other side of the room or to another room to get




any programs that have been downloaded from the Internet may or may not still be

available. Bookmarks, e-mail addresses, phone and fax numbers, dial-up connections,

Close all programs, shut down Windows, and turn off your computer. Then remove thecables from the back of the case.

2. DIAGNOSING FAULTS AND FAILURE OF THE COMPUTER

SYSTEM

When your computer goes wrong and you have lost all hope the normal practice is to reformat

your computer. This will ultimately resolve any software issues, viruses or any other nasties and

give your computer a fresh start. But what happens if you have reformatted your computer and

the problem still exists?




Hard Disk

Motherboard

This isn’t the full list, obviously depending on your computer issue ie if you just don’t getsound then it could be a sound card issue, likewise with graphics cards but if it is a random fault

then either of the above could be the cause.

Memory – this is relatively easy to diagnose. Search Google for a memory tester.

Generally these can be burnt onto a CD (or Floppy if you are still in the dark ages), booting from

the CD then enters the memory test. This will persistently check the memory for errors. It is wiseto leave this on for several hours or overnight. It will alert you if the memory fails.

Power Supply – this is an interesting one. People assume that if the power supply does

fail then you simply would get no life from your computer. This is actually not true. I have hadcomputers that randomly turn off at any given time, computer that have the power light on, but

do not boot etc and it has turned out to be the PSU – I would suggest looking at this as being one

of the first problematic areas. Testing it can be annoying. Really the only way is to get a volttester and check the voltage and current coming out..

Hard Disk – this is annoying as if you hard disk does go, unless you have been sensible

and done a regular backup of your important data, you stand to lose everything. These can go at

any time and generally you will hear a harsh sounding clicking noise coming from your

computer. If this is the case you need to replace the hard disk . Get someone who then knowswhat they are doing to try and recover your old data for you.

If none of the above solves you issue then you is possibly looking at the motherboard or

any other cards or devices you have. Strip everything down to the very basics. Remove all soundcards etc and any other PCI devices that are not essential. If you have more than one stick of ram

then leave only one and see if the machine will boot.

3. RE-ASSEMBLY

* After you have already fixed all the faults that has been diagnosed, you have just to put

all the necessary thing to make the computer back to its original looks.

- make sure that all the peripherals in the system unit are placed in their respective slot

like:a. Memory

b. Video Card (if not on-board)

c. Sound Card (if not on-board)d. Land Card (if not on-board)

e. Hard Disk

f. Power Supply

g. CD Romh. Floppy Disk

- put the sidings of the system unit and lock the screw.




4. TEST-RUNNING THE COMPUTER

* Open the computer system and then test the entire program you have installed in the computer

and make sure that it is in good running condition.

Reading Information

Information 1.1-1

Characteristics of Materials Used in Specific Projects

The student must relate material properties to product and process quality. These are the

factors that must be taken into consideration when choosing the right material for their

components and assemblies:

1. Selection of material

Material selection is one of the most common tasks for designengineering. The ability to assess the material’s impact on the

performance of a product is crucial for reliable performance. Sometimes, buyers are also considering the label or

name of the company which are producing great quality of materials

and are known in the market. Examples are the name HP for printer

and Intel for some computer hardware.

2. Testing of material

The testing of material properties is widely understood to be the key to obtaining data for

a project, performing failure analysis, or understanding material interactions. Material testingalso provides information on the quality of incoming and outgoing products. Inspection test

equipment and techniques are demonstrated for a wide range of materials and assemblies during

the class. This provides the participants with both knowledge of the common failure modes.

3. Cost of material

The cost of material is also considered when buying or selecting materials for a specific




Before planning and designing takes place, you should evaluate the material options and

system requirements. Teachers should add several useful reference manuals to their librariessuch as installation of hardware, networking, troubleshooting as well as basic PC Operation and

Internet for additional information that the students may used in their projects.

The characteristic of the materials to be used for specific project must be:

of good quality

- This is the most important factor when choosing materials to buy. Productswith good quality are long-lasting and safe to use because you know that it

follows certain standards before being commercialized.

reliable

- It means that you can be sure that it will perform its function well, will

operate safely and will give the best it could give.

suitable for the application/purposes

- Choose the materials which are very necessaryto make the project possible. Making a list of

Characteristic of common materials for increased security is also a great

factor in the design and planning process. Evaluation of longevity criteria and

assessment of site environmental factors are vital to project planning.

Specific knowledge about the project and general common sense must

dictate design and material selection. Although many materials can offer enhanced protection, often the most cost-efficient and readily available material that provides

reasonable life expectancy for the project must be considered.




INFORMATION SHEET 1.1-2WORKPLACE STANDARDS AND SPECIFICATIONS

What is a standard?

"Standards and specifications are documents that stipulate or recommend 1) minimumlevels of performance and quality of goods and services, and 2) optimal conditions and

procedures for operations in science, industry, and commerce, including production, evaluation,

distribution, and utilization of materials, products, and services.

Types of standards:

Category, type, dimension, structure, equipment, quality, grade, component, performance, durability, or safety

Methods of manufacturing, methods of designing, methods of drawing, methodsof using, or methods of operation of safety condition of production

Methods of testing, analyzing, appraising, verifying, or measuring

Terms, abbreviations, symbols, marks, preferred numbers, or units




when the older standard was in force. The Engineering Library DOES NOT

maintain historical or superseded standards.

What is a specification?

Specifications are concise statements of requirements for materials, products or services

that are to be purchased by an industry or government agency. Specifications are limited to aspecific project or government agency. Standards are specifications that are recognized as themost practical and appropriate current solution, that is agreed upon by a recognized authority, for

a recurring problem.

Employer or Employer Representative at the Workplace

The employer (in an industrial establishment) or the constructor (on a construction

project), has very important responsibilities for the workplace. This responsibility cannot be

delegated or conferred to another party by a similar process. In the case of students who are not

paid, ideally the employer should:

be aware that the student will be in the workplace and know what type of workthey will be undertaking

ensure that the student is protected by job-appropriate safeguards

ensure that appropriate personal protective equipment is identified and used Insmall workplaces, the employer may also be the supervisor and will have to be

present for the placement assessment. In larger workplaces, the employer may ask

another company representative or the supervisor towork with you through this process.




INFORMATION SHEET 1.1-3

PROCEDURES IN OBTAINING AND CARRYING OUT WORK INSTRUCTIONS

FOLLOW INSTRUCTIONS

Follow instructions. This sounds easy enough. It isn't. For some people, it's the key to

most of their academic problems. They read or hear one set of instructions, but their teacher has

given different instructions.

Some students deliberately ignore instructions. They "wing it." They think they canscrape by, doing any old thing they choose. They're wrong. But they refuse to change.

It doesn't matter how good a job you do if you do the wrong job. You're going to get a bad grade.

Doing a job well begins with understanding exactly what the job is.

Start paying attention to instructions. That's where to begin your program of self-

improvement.

SETT ING UP OR I NSTALL ING A PRINTER I N MICROSOFT WINDOWS.

ISSUE

Setting up or installing a printer in Microsoft Windows.

Solution

the Setup or Install file.3. Follow the installation wizard and your printer and its associated software should be

installed successfully.

Installing a printer only using the drivers

In addition to the above steps a users can install a printer in Windows only using the

printer drivers. This is recommended if you only want the printer to be installed but not

the additional printer software programs that are often included with the installation and

you've download drivers.

A listing of printer drivers and software downloads can be found through our printerdrivers page.

Note: if you've installed the printer doing the above steps these steps should not benecessary unless you encountered errors.

1. Connect the printer to the computer and a power outlet and make sure it's on.

2. Click Start, Settings, and Control Panel.

3. In the control panel double-click the Printers or Printers and Fax icon.4. In the Printers window click the Add a printer icon.

5. After completing the above steps the Windows Printer Wizard will appear. Click

Next, to start the wizard.6. Windows will prompt you if you're installing a Local or Network printer. If the

printer is connected to your computer choose Local printer attached to this

computer and click Next.

7.

When prompted for the location of the drivers for the printer. Browse the computer tothe directory of your drivers or point it to the CD that was included with your printer.

Qual i ty Checking Procedures Effective management checks are an important means of providing assurance of the

integrity and security of the benefit processes. They are also useful in identifying training needs;

indicating possible weaknesses in procedure and ensuring the section meets its accuracy targetset for Best Value Performance Indicators purposes.

Methodology

The teacher will be the assessor. Students will be randomly assigned that will: 1.) act as

Quality Checker; 2.) responsible for monitoring and coordinating the checking arrangements

and; 3.) must generate reports when receiving the equipments.The Quality checker will record the date of receipt, name of the materials purchased,

quantity, official receipt number, signature of the person who bought the materials and signed his

name afterwards. The Quality checker will identify if the materials are in good condition or

damage and /or needing for replacements. This will also be recorded on his report.

Feedback

Once the Quality checker has completed all the reports, the assessor will check if theQuality Checker provides all the data needed in the report.

Carry out work in accordance with policies and procedures

Carry out basic repairs to computer equipment by replacement ofmodules/sub-assemblies

Unit Descriptor

This unit deals with the repair of computer equipment by replacement of slot/plugconnected modules/sub-assemblies. It encompasses safe working practices, following written

and oral instruction and procedures, basic testing techniques, dismantling and assembling

apparatus and disconnecting and reconnecting components.

RANGE STATEMENT

This relates to the unit as a whole providing the range of contexts and conditions to which

the performance criteria apply. It allows for different work environments and situations that willaffect performance. This unit shall be demonstrated in relation to carrying out repairs to personal

computers and servers. The repairs shall be limited to:

Replacement of at least three slot/plug connected modules/sub-assemblies havingdifferent functions and in which the fault has been previously established, and

Repair to broken wires/ribbon cable to industry standards, that may include,minor soldering

Note:

1. Examples of Modules include self contained hardware components such asmotherboards, memory cards storage devices

2.

Examples of Sub-assemblies include collections of integrated components thatmay form part of a module that are designed to be replaceable for servicing, such

as the component part of a hard drive module or motherboard.




The computer saves its information on a disk , most often the hard disk, and the users determines

where and when the file or document is saved.

Folders & Directories

On the disk are directories or collection of folders. These directories or

folders could be compared to a filing cabinet. All files are stored in a

directory. Most hard disks have many directories or folders and files can be stored in any of them.

Directories can have sub-directories and sub-sub-directories manylevels down. The directory immediately below the current directory is called the child directory.

The directory immediately above the current one is called the parent directory. The top of thedirectory structure is called the root directory.

When a user adds or installs a new program on the computer the installation process will usually

create a new directory or folder to store the application's files.

Users can create and delete directories or folders as the need arises. Older operating systems

require that the directory be emptied of files before it can be deleted. When removing a directory

always check before deleting it to make sure that it doesn't contain files you need.

You can easily move files from one folder or directory to another using menu commands, drag& drop using the mouse or a file utility. It is important to understand your computer's

directory structure as a file can be misplaced if it is saved in the wrong directory.

One of the main problems new users have is creating a filing system. Modern operating systems

address the 'filing problem' by automatically creating a (My) Documents folder. By saving filesor documents in this folder you will always know where

You may have to adjust some of the settings for the printer to get the output you want. Density

adjustments determine how much ink is placed on the paper or how many dots per inch (DPI).

Draft quality will printer quicker but creates a fainter copy (less dense). Modern Software has a

Preview option which show what the page will look like when it is printed. Portrait prints the

document up and down. Landscape prints the document on it's side. Most software allows theuser to adjust the margin width or the blank space at the top, bottom, left and right edge of the

paper.

Learning style a. Visual - The visual learner takes mental pictures of

information given, so in order for this kind of learner to retain

information, oral or written, presentations of new informationmust contain diagrams and drawings, preferably in color. The

visual learner can't concentrate with a lot of activity around

him and will focus better and learn faster in a quiet study

environment.

b. Kinesthetic - described as the students in the classroom, who

have problems sitting still and who often bounce their legswhile tapping their fingers on the desks. They are often

referred to as hyperactive students with concentration issues.

c. Auditory- a learner who has the ability to remember speeches

and lectures in detail but has a hard time with written text.

Having to read long texts is pointless and will not be retained

by the auditory learner unless it is read aloud.
