Course

PRESENTATION

This course aims to serve as a basis in PC-Assembling and Maintenance of microcomputers. Some basic concepts about its components will be shown.

This course will not answer all the questions related to micro-computer science, nor could it be otherwise since computer science evolves very quickly.

In order to obtain more detailed answers on the subject and to increase the knowledge about microcomputers, we recommend the books of Laércio de Vasconcelos, which bring together a vast technical knowledge of its author. Among them are:

– How to Mount, Configure and Expand Your PC with AMD and / or Pentium, Semprom, Celerom, Pentium IV (all microprocessors)

Level 1 – Basic Hardware
Level 2 – Advanced Hardware

– Pentium Expert and Portal Dekassegui . with

We appreciate any comments, suggestions or corrections that will allow us to improve our course.

NEW

IN THIS MODULE, YOU WILL LEARN STEP-BY-STEP, CHANGE A MOTHERBOARD.

Typical Components of an ATX Motherboard (Motherboard)

Cabinet Inside (CPU)

To upgrade your System by replacing the motherboard follow these steps:

1) Remove the motherboard by loosening the sockets, most motherboards are connected to the chassis with four to eight connectors. Loosen the generally plastic tabs, place the part in a container so you do not miss the parts because they are very small. Remove the plate by sliding it slightly forward of the chassis and then pull it out. If you are installing a new power supply, note the wires (usually four) that hold, remove the power supply, put the new power supply in place, and reinsert the wires.

2) Install the new motherboard. Slide the new card into the appropriate location on the chassis. The mounting locations should be aligned and should be in the correct position. Mount the motherboard with the wires left in step 2. Simply tighten the connectors slightly, without tightening them too much so as not to damage the motherboard.

3) Remove the plates and cables. Turn off your PC and unplug the wall. Disconnect the mouse, keyboard, monitor, printer, and any other external cable. Remove the metal case from the PC case and see everything you need to power off and disconnect before you can connect the motherboard. In some cases, you will have to disconnect the hard disk or other hardware.

Use an antistatic wrist strap following the manufacturer’s instructions when working inside your PC. Remove all wires that are connected to the auxiliary boards (figure A), carefully remove the boards and place them on a clean, flat surface. If your new motherboard includes components such as a LAN or integrated sound connector, separate the motherboards that you will need to reinstall. Label each cable with tape and note where it was connected. Disconnect the electrical wires (Figure B), the diskette drive cable (Drive), and connectors (Figure C). Note which cable is connected on the primary channel and which is the secondary. Finally, disconnect the small connectors where the switches and LEDs on the front panel go, as well as any other cable that is connected to the motherboard.

4) Install RAM and processor. Before mounting the motherboard to the carton, carefully insert your new RAM modules into the slots (Figure A) until the latches on each side of the slots snap into place. Comee with the slot that is identified as “Bank 0”. Look for the CPU location, lift the side and place the CPU (figure B) carefully, making sure that the CPU connection matches the specific location connection on the motherboard. Firmly hold the CPU and its place where it will insert.

Install the cooler (figure C) that comes with the CPU (if you have not included any, you will have to buy one) and connect to the designated connector on the motherboard,

5) Reinstall the auxiliary boards and all cables. You can now reinstall the boards and cables you removed earlier. Work slowly and carefully and check all connections. Make sure you have the additional boards with all connectors that you had previously switched off. Reconnect the mouse, keyboard, monitor, printer, and other external devices. Do not put the case back on your PC until you are sure everything is working perfectly.

6) Turn it on. Plug in the power cord and turn on your PC. I know how to emit an electronic sound and you see a message in the video, that’s a good sign. Windows will need to start the PC several times as your new hardware adjusts. Windows should detect certain components as a network, the sound of the USB 2.0 ports before starting the wizard to add new hardware. Follow the instructions in your manual to install the motherboard drivers. If nothing happens, your PC will halt at boot time, shut down, unplug the power, and recheck all connections. If this does not work, call your motherboard manufacturer for service.
