Steps of disassembling a PC
Steps of disassembling a PC
To Disassemble PC
1. Prepare all your tools.
a. Long Philip Screw Driver
b. Soft Wide Bristle Brush
2. Before opening the system case, be sure to turn off the system unit. Turn off and unplug the AVR from the wall socket as well. After that, unplug all the cables connecting to the back of the system unit. After clearing all the connected cables, put the system unit on an empty working table.
3. Touch the unpainted part of your system unit with your bare hands to remove the ESD of your body. This is an important part before opening your system case. You might destroy your RAM, Chipsets and other components of your motherboard.
4. Remove the screws of the side cover opposite to the side where the ports are. By most system cases, if you are facing the back of the system unit the right side cover is to be removed. Return the screws back to the screw holes to avoid losing them.
5. Once the side cover is removed, turn your system side down where the opened side of the system unit should be facing upward where you can comfortably look down on the inside of your system case.
6. We are now ready to remove the components inside of the computer. The first thing we need to do is remove the power supply. To be able to remove the power supply, remove first the molex connectors (the white plastic connector at the tip of the wires of the power supply) or the motherboard power connector, drive power connectors, the floppy drive power connector, the sata power connectors and the four pin 12-volt motherboard connector. With all power connectosr are removed from the motherboard and drives, the power supply is now ok to be removed as well. Always have the removed components placed in a remote and safe place away from where you are performing computer disassembly.
7. With the power supply removed, the data cable should be removed next. This includes IDE, SATA, and floppy drive cables. Secure the removed data cables.
8. Next to remove are the RAM, Video Card and other card peripheral components. Again have them secured in a safe place and put the screws back. Clean the connector edges of the card peripherals by rubbing the gold colored edge moderately with a rubber eraser then brushing off the shredding. Do not attempt to clean the edge by blowing or brushing it off with your fingers. Our body is acidic and you might only cause the edges to tarnish faster.
9. Remove all drives. This will include your hard drive, cd/dvd drives, and the floppy drive.
10. Since all peripherals where removed, the next thing to do is to remove the front panel connectors. This will include the USB, Front Panel (FP) and Audio header. If you are not sure of which connector is being match to, write down or document the connections and orientation of the connectors before removing them from the headers. Remember that not all motherboards have the same header configuration so be careful and watchful while documenting.
11. After removing the header connectors, we are now ready to remove the motherboard. To remove the motherboard, locate first all the screws and lightly unscrew all screws alternately. With this technique, we are reducing the risk of warping or bending our motherboard. It may not have a large impact on the bending of the motherboard but still it does have even a little. Upon lightly loosening all screws, remove all screws then. Remove the motherboard by carefully and lightly pulling it away from the I/O shield. Why? because we need to free the ports that are fitted from the holes in the I/O shield. After freeing the motherboard ports from the I/O shield holes, lift up the motherboard and put it on the safe place.
12. Clean the system unit chassis with your brush, also clean your motherboard and the rest of the peripherals being removed.
when disassembling the computer, tools such as proper screws and antistatic mats should be available. Also, we have to make sure that all power sources are switched off to avoid ESD damage to occur. Moreover, we should be careful when removing the components from the motherboard and follow the instructions correctly to prevent any mistake from happening.
