Replacement of the motherboard. Basics

Any laptop or personal computer is not an indivisible device, but consists of various functional units. Sometimes the example given in the example of the children's designer is quite acceptable.

The basis that connects all the components together is the motherboard, or motherboard. You can say that without it there is no computer. It is not difficult to guess that replacing the motherboard is a relatively complex operation, requiring care and implementation of certain rules. However, with sufficient accuracy this work can produce any.

A person who is little familiar with computer technology, it may seem that replacing the motherboard is a fairly rare operation. In fact, there are three main reasons for this:

- the need to replace a failed motherboard with a new one;

- the desire to gain access to additional settings;

- complete platform change.

Let us dwell in more detail on each of these points. Being a sophisticated electronic product, the board includes capacitors. They come in several types: classic "kegs" with electrolyte inside and solid-state ones. The first have a larger capacity, but are cheaper at the same time, so some motherboard manufacturers use them. As a result, the cost of production can be significantly reduced. The only drawback of electrolytic capacitors is their short service life (in comparison with solid-state capacitors). Overpriced voltage, low-quality electrolyte, high ambient temperature, drying - all this can lead to the fact that the capacitors on the motherboard swell and cease to perform their functions. They can be replaced by restoring work. But if the failure is repeated, then the replacement of the motherboard can solve the problem. Moreover, models with solid-state capacitors are more technological and lack these disadvantages (although their capacity is lower).

The next reason that you might need to replace the motherboard is new features. Many CPUs allow for an increase in their operating frequency, the so-called "overclocking", which can not go unnoticed by application enthusiasts who are demanding the speed of mathematical calculations. Overclocking is also possible for memory modules. In addition, some processors contain inactive kernels, which can be activated by including the required option in the BIOS of the motherboard. If there are no options for enabling the required functions, and the accessories support them, then you have to resort to replacing the motherboard.

And the last reason is the decision to purchase a new processor, with which this board can not work.

The replacement begins with the disconnection from the old motherboard of all trains (both interface and power). Then, all the elements that prevent dismantling are removed from the housing. These can be expansion cards, power supplies. Having unscrewed the fixing bolts, the motherboard can be removed. Next, we remove the cooling system and the processor itself. We take out the memory modules.

Installation of the motherboard purchased for replacement is performed in the reverse order, starting with the central processor. The fixing bolts are screwed into special sleeves, thanks to which a gap is left between the board and the housing. Therefore, at first you should make sure that the screwed holes and holes of the new motherboard correspond. If this is not observed, then we rearrange them in the correct holes in the metal of the case. Sometimes plastic clips are used instead of bolts, they must also be correctly set. After that, fix the board in the case. It is recommended that under the edges of the motherboard and memory slots, put a rubber band (stitch) - this will prevent the inevitable bending during the connection. Connect all loops according to the instruction manual.
