  • 1. PC Assembly,Troubleshooting & Networking
  • 2. Part IIntroduction
  • 3. Parts of Computer► Motherboard► CPU► Memory► Video Card► Power Supply► Hard Disk► CD/DVD Rom Drive► IDE Cable
  • 4. Motherboard- A motherboard is the central or primary circuit board making up a complex electronic system, such as a modern computer. It is also known as a main board, baseboard, system board
  • 5. Motherboard Design
  • 6. Microprocessor►Amicroprocessor -- also known as aCPU or central processing unit -- is acomplete computation engine that isfabricated on a single chip.
  • 7. Microprocessor Design
  • 8. Memory►Memory- is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage
  • 9. Video Card►A video card, (also referred to as a graphics accelerator card, display adapter, graphics card, and numerous other terms), is an item of personal computer hardware whose function is to generate and output images to a display.
  • 10. Video Card Design
  • 11. Power Supply►In a personal computer (PC), the power supply is the metal box usually found in a corner of the case. The power supply is visible from the back of many systems because it contains the power-cord receptacle and the cooling fan.
  • 12. Power Supply Design
  • 13. Hard Disk►Hard Disk Drive (HDD), commonly referred to as a hard drive, hard disk or fixed disk drive, is a non- volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
  • 14. Hard Disk Design
  • 15. CD ROM►CD-ROM (an abbreviation of "Compact Disc read-only memory") is a Compact Disc that contains data accessible by a computer.
  • 16. CD ROM Design
  • 17. IDE Cable► Thiscable will work fine in two-drive configurations, but there is a drawback: its suboptimal for one-drive installations. These high-speed disk cables really should always have a drive on the physical far end of the cable to reduce noise on the bus, but this cable puts the single drive in the middle

  • 25. 2. Optional) Remove the Motherboard Tray
  • 26. 3. Replace the ATX Connector Plate
  • 27. 4. Determine Motherboard Mounting Location
  • 28. 5. Install the Motherboard Standoffs
  • 29. 6. Fasten the Motherboard

  • 39. Troubleshooting Tips for New Monitors1. The picture does not appear2. The Screen is not synchronized3. The position of the screen is not in the center4. The screen is too bright or too dark5. The screen is shaking
  • 40. Troubleshooting Tips for a New Motherboard► System has no power at all. Power light does not illuminate, fan inside the power supply does not turn on, and indicator light on keyboard does not turn on.► System inoperative. Keyboard lights are on, power indicator lights are lit, and hard drive is spinning.
  • 41. Troubleshooting Tips for a New Motherboard► System does not boot from hard disk drive, can be booted from floppy disk drive.► System only boots from Floppy Disk.

  • 44. Troubleshooting Tips for a New Motherboard► Missing operating system on hard drive.► Certain keys do not function.► Keyboard is locked, no keys function.
  • 45. Trouble Shooting Tips after Installing a New Video Card► Check that the card is seated properly in its expansion slot.► Ensure the display cable is securely fastened to the cards display connector.► Make sure that the display and computer are plugged in and receiving power► If necessary, disable any built-in graphics capabilities on your motherboard.► Make sure you selected the appropriate display device and graphics card when you installed your enhanced driver.
  • 46. Basic Troubleshooting Tips after Installing a New Hard Drive► Verify compatibility► Check all cards► Check all connectors and cables► Verify jumper settings► Check your power-supply specifications► Verify the drive-type settings in the system setup program► Check for viruses
  • 47. Additional Tips for HDDAfter you install your new drive, your computer will not boot, and no error message appears on the screen.The screen remains blank when you power up the system.The system does not recognize the drive. The dealer partitioned and formatted the drive for you in the store, but the drive does not respond when you install it.
  • 48. Additional Tips for HDD The system hangs in FDISK or fails to create or save the partition record. The system error message, "Drive not Ready," appears. The FDISK error message, "No Fixed Disk Present," appears. The drive does not format to full capacity. The DOS message "Disk Boot Failure," "Non- System Disk" or "No ROM Basic - SYSTEM HALTED" appears. The system error message, "HDD controller failure" appears.

  • 50. PART V►PC MAINTENANCE
  • 51. PC Maintenance• you use your computer more than a few hours per day, we suggest you not to turn off your computer at the end of the day. Instead turn off only the monitor to save electricity. Daily power up and down makes the components exposed to high and low temperature cycles that are not good for the life-time of the components, particularly the critical ones such as hard drives, CPU, and memory. The temperature cycle would result in expansion- shrinking cycle for the components. The life-time of electronic components would be increased if they are run at constant temperature with adequate ventilation.
  • 52. PC Maintenance• If your area experiences a few times of power outage per year, it is necessary to use a UPS. Sudden power downs while the system is running may cause severe damage to hard drives.• A tape backup and a lock to make systems hard to move are worthy investment for critical data.
  • 53. PC Maintenance• Use your hand to touch and feel the cover of your computer at least once a week. The cover should be at room temperature. If it feels warm there may be a problem! Check to make sure that the cooling fans on the power supply and CPU are working properly. Clean the air pathway on the back of the power supply on a regular basis.
  • 54. PART VI►Computer Networking
  • 55. TOOLS IN NETWORKING► RJ-45► Twisted pair cable► Crimp tool► Ethernet hub► router► Network Adapter Card (NIC)
  • 56. RJ 45► Eight-conductor data cable contains 4 pairs of wires. Each pair consists of a solid (or predominantly) colored wire and a white wire with a stripe of the same color.
  • 57. Twisted Pair Cable► Twisted pair cabling is a form of wiring in which two conductors are wound together for the purposes of canceling out electromagnetic interference (EMI) from external sources, electromagnetic radiation from the UTP cable, and crosstalk between neighboring pairs.
  • 58. Crimp Tool► crimpsRJ45 modular plugs. Simply place the plug with the cable in the crimp tool and squeeze the grips together, thus causing the plug to bite into the cable.
  • 59. Ethernet Hub► An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fiber optic Ethernet devices together, making them act as a single segment.
  • 60. Router►A router is a device that determines the proper path for data to travel between different networks, and forwards data packets to the next device along this path.They connect networks together; a LAN to a WAN for example, to access the Internet.
