Cpu presentation

  1. 1. By: Mudit K. J., Harpreet, Perry, Karan
  2. 2.  CPU stands for Central Processing Unit Central Processing Unit is like the brain of the Computer
  3. 3.  The CPU is one of the main portions of the computer, that carries out instructions to the computer program CPU performs arithmetical, logical and input/output operations The designs of the CPU may have changed, but they all perform the same operations The First CPU was made in the 1940s and was ran with the first computer the EDVAC (Electronic Discrete Variable Automatic Computer). The EDVAC was one of the first functional Electronic Computers
  4. 4.  The CPU will haveLGA – Land Grid Array - Used to connect to Sockets - The sockets will have a model number that is used for that certain processor775 socket is used in the Pentium 4 processor
  5. 5.  PGA– Pin Grid Array - Was used in previous models of the processor
  6. 6. Pin Grid Array This is a Old CPU Model I486 DX2
  7. 7. Pentium 4 ProcessorThis is the CPU modelwe will be showing
  8. 8. Land Grid Array
  9. 9.  Unplug all electrical connections This includes the electrical power to the motherboard processor and the fan cable Put in the Anti-Static Wrist Strap to a non- painted area/metal
  10. 10.  There are four fasteners connected from the cooling assembly to the motherboard Gently rotate 90 degrees to the direction indicated on top of the fastener Never do a counter-clockwise rotation When a fastener is released, alignment line on top will be parallel to the cooling assembly You will need to use a flat-tip screwdriver to rotate the fastener caps Do not let the screwdriver tip slip off the fasteners
  11. 11.  Pull the fasteners gently upward, but you should here a snap from each fastener on the motherboard Place the plastic protection covers over the bottom of the cooling assembly to protect the fastener tips Disengage locking lever tab while holding the load plate in position Slowly release load plate while you move the load lever into full open position
  12. 12.  Remove Processor using a straight up vertical direction Do not tilt or slide the processor Close the processor load plate, lock the lever and replace socket protective cover Excess Thermal material can be removed with a soft lint-free cloth
  13. 13.  Core Processor Heat Sink Fan Assembly Compressed Air to remove debris or Foreign objectsAnti – Static Wrist Strap
  14. 14.  Lookat the pictures What Do you see There is a lever to open the CPU, and Protective cover Levers are only in the new motherboards
  15. 15.  UseCompressed Air to remove Debris or foreign objects Never use your finger, cloth or brush to remove debris This damages the pins
  16. 16.  Remove the processor from its protective cover Handle the processor by the edges Never touch the bottom of the processor Carefully remove processor from its protective cover Inspect it for damage
  17. 17. There is one way for a processor to be inserted back into its socketA processor has many pins, but there is only ONE pinThis pin is known as Pin #1, this is where you put the processor in its place
  18. 18.  Placethe processor over the socket keys, look for a socket that is different to other sockets DoNOT drag the processor across or place it the wrong way This Pin must correspond to the socket
  19. 19.  After inserting the processor Lower it to the load lever and secure it under the locking tab Should look like this
  20. 20.  Installthe Cooling Assembly which has a heat sink and fan Remove the protective plastic cover from the bottom of assembly Do not touch the bottom of the assembly or the thermal compound
  21. 21. Thermal Compound Material
  22. 22.  Before installing the cooling assembly that has a heat sink and fan Apply the thermal compound material on the processor Put enough compound material so that it is evenly distributed Use a material like a old card, etc to evenly distribute it
  23. 23.  Position the fan over the processor The motherboard should have four holes around the processor The holes are for the cooling assembly to be placed The cooling assembly will have 4 fasteners Use a pencil’s end (eraser) to push down the fastener Connect a fan electrical cable to the motherboard fan connection

  25. 25.  Visitcomputerpartcpu.wikispaces.comWebsite has more Tutorials on removal and installation of CPUs on other versions of the computer hardware models
  26. 26. Computer Manuals Pgs 205 to 218Tutorial videos mostly from Youtube
