1 PC Maintenance Training

2 After completing this lesson, you will know:
Computer hardware familiarization Assemble a computer system including installation of the motherboard, floppy and hard drives, CD-ROM, and video cards Install and manage Windows XP operating system and Microsoft Office 2003 Add peripherals and multimedia capabilities Basic Troubleshooting & Maintenance

3 Computer is a machine for manipulating data according to a list of instructions or programs Collects, processes, stores and output information

4 So why use a computer? Work faster & be more precise.
Use the same piece of information again in different documents. Make calculations without errors and correct spelling mistakes. Present more professional looking work. Make as many copies and different versions of electronic documents as you like. Store and keep track of your (electronic) documents. Send (electronic) mail and documents to distant relatives and business relations within a matter of minutes. Find information you need, available on one of the millions of computers worldwide that are connected to the Internet.

5 Computer System Computer Case – contains all the major components
Monitor – is a device that display text & images generated by the computer Printer – is a device that produces a copy of documents you create Keyboard – is device that lets you type information & instruction into a computer Mouse –is a hand held device that lets you select and move items on the screen Speaker – lets you hear sound generated by your sound card

6 What’s inside a computer?
Processor/CPU Motherboard RAM (Random Access Memory) Hard disk drive Video card Audio Power supply Floppy drive Networking CD-ROM Drive

7 What’s inside of the Computer?
Processor – also known as CPU or the Central Processing unit Ex. Pentium 4 2.4Ghz 400MHz Processor Type – Pentium 4 Clock Speed – 2.4 Ghz (speed at which operations took place inside the CPU) System Bus – 400Mhz (the speed at which RAM memory was accessed)

8 What’s inside of the Computer?
Motherboard – also known as the mainboard. It contains circuit that perform various functions.

9 What’s inside of the Computer?
Memory – is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage. Ex. RAM, ROM, Bios etc.

10 What’s inside of the Computer?
Hard disk drive – a fixed computer storage medium.

11 What’s inside of the Computer?
CD-ROM drive – Compact Disk/Read-Only Memory drive, a device that can read information from a CD-ROM.

12 What’s inside of the Computer?
Sound Card –is a computer expansion card that can input and output sound under control of computer programs.

13 What’s inside of the Computer?
Modem – The word "modem" is a contraction of the words modulator-demodulator. A modem is typically used to send digital data over a phone line.

14 What’s inside of the Computer?
Network Interface Card –also known as LAN card. A PC interface to network cabling. It is a piece of computer hardware designed to allow computers to communicate over a computer network

15 What’s inside of the Computer?
Power supply –changes the alternating current (AC) that comes from an outlet to the direct current (DC) that a computer can use. Note: the capacity of power is measured in watts.

16 What’s inside of the Computer?
Floppy drive –stores and retrieves information on floppy disk

17 “A journey of a thousand miles began with a single step .”
Proverbs “A journey of a thousand miles began with a single step .”

44 Troubleshooting & Diagnostics

45 Troubleshooting & Diagnostics
Trouble: Start up problems No power Fan is not running No LED Cause: Power cord/bad power outlet AVR or UPS not power on Power supply

46 Troubleshooting & Diagnostics
Possible Solution: Try another cord /outlet Turn on the AVR or UPS Replace power supply

47 Troubleshooting & Diagnostics
Trouble: Display Problem The PC is turned on but the display isn’t working Cause: Power cord is unplugged from the outlet or from the PC Display power switch is turned OFF Video cable is unplugged to the PC Video card problem/board problem (if on board)

48 Troubleshooting & Diagnostics
Possible Solution: Plug the power cord to the outlet or PC Turn on display power switch Plug video cable Replace video card/board

49 Troubleshooting & Diagnostics
Trouble: Mouse problem The mouse does not respond at all The mouse moves poorly Cause: The mouse is not properly plugged in Dirt on the rollers or the ball Defective mouse Defective mouse port (serial/ps2)

50 Troubleshooting & Diagnostics
Possible Solution: Plug the mouse properly Turn the mouse upside down. Rotate the little door to allow the ball to drop out. Rub the ball to clean it, and scrape the rollers to get the dirt away. Replace mouse (PS/2) or USB if problem with port.

51 Troubleshooting & Diagnostics
Trouble: Keyboard problem Keyboard does not respond Cause: Keyboard is not connected

52 Troubleshooting & Diagnostics
Possible Solution: Try plugging again. Replace keyboard (PS/2) or USB if problem with port.

53 Troubleshooting & Diagnostics
Trouble: Hard disk problem Hard disk not detected Hard disk error Cause: Loose cable or no power Bad block/sector

54 Troubleshooting & Diagnostics
Possible Solution: Secure data connector/power connector Replace HDD

55 Troubleshooting & Diagnostics
Trouble: Audio problem No sound heard from audio Cause: Volume control Device driver not installed properly

56 Troubleshooting & Diagnostics
Possible Solution: Check the volume control check the audio cable Reinstall device driver

57 Troubleshooting & Diagnostics
User problem: Powering off without properly shutdown the computer Placing water, sodas, or any liquids on the top of CPU Installing unnecessary application and highly graphical games that can hamper the CPU Fixing the computer even no trouble detected Removing cover of the unit/PCI slots that exposes the CPU to insects and rats.
