The motherboard is the backbone of the computer, and if it fails, the machine crashes. It happens that the board cannot be repaired, or its cost is equivalent to buying a new one. In this case, you can independently replace the old motherboard with a new one.
Instructions
Step 1
First, disconnect all wires from the system unit, including the power cable. Now inspect the system unit to understand how it is disassembled, because with all the variety of modern system units, it is impossible to predict a specific mounting system in advance. Most system units can be disassembled by unscrewing a few screws on its back cover. Some system units, instead of screws, are equipped with special latches, and in order to disassemble the system unit, you do not need to unscrew anything. Either way, you need to remove both side covers to gain full access to the inside of the computer.
Step 2
After the covers are removed, depending on the size of your system unit, you will understand if there is a need to remove the optical drive and hard drive. So, if the block is large enough, then the motherboard will most likely be pulled out without removing the hard drive and optical drive, and if the system unit is compact, these actions cannot be avoided. Let's say your case is difficult and you have to take additional steps. In this case, use a screwdriver to remove the screws securing the hard drive, optical drive, and possibly floppy drive, if available. The cables and wires that connect them to the motherboard should be disconnected from the side of the motherboard, noting the place of contact.
Step 3
Now you need to disconnect the power supply from the motherboard, and after unscrewing the screws securing the power supply, remove it from the system case. Before you can have full access to the board, you will need to unscrew all the screws from the back of the system unit that secure the video card, sound card, network card and other devices, whose fasteners are located on the back of the system unit. Now only a few screws or latches prevent the motherboard from being removed, with which it is attached to the case of the system unit. Find the places of fastening and disconnect the board from the case.
Step 4
The penultimate step remains - to disconnect the cooler, processor, and RAM sticks from the motherboard. The cooler is usually fastened with latches, and it will not be difficult to remove it. There is a processor under the cooler, which is attached to the motherboard with a special mount. Remove the processor and set it aside. All that remains is to remove the RAM strips, and the motherboard can be sent to rest. To install a new board, it is enough to follow the entire sequence in reverse order - it will not be difficult if you managed to get to this point.
