Repair your PC video card

What can you do, when your video card stopped working?

When you warm up the graphics card from below (under the chip), try to keep the hairdryer perpendicular to the plane of the textolite, otherwise I could not shoot and warm at the same time. Also, do not touch the small components of the card located on the rear side (you can easily shift them, taking into account the hot solder under them).

In the video above, I did not show the whole procedure, as you understand. From the bottom it is necessary to heat long enough (3-5 minutes), so that the smoke from the flux, which you could notice, began to rise quite intensively above the board (this is evidence that the board has warmed up well). The first stage will be “boiling” and bubbling flux – this is normal.

Also do not hesitate to warm up the space under the crystal itself (you can do it through the board). The main thing: do not delay the hair dryer in one place – smoothly move it around the area (to exclude places of local surface overheating). Keep the bell of the hair dryer at a distance of 2-3 centimeters from the surface to be treated. I personally put the flow of air at an average value, the temperature that shows the soldering station – 420-450 degrees Celsius. The second value is the limit for my “Ya Xun 880D”.

The temperature spread here is related to the fact that the sensor itself is located directly in the handle of the thermofan, and the temperature of the air at the outlet of the dryer is already different (lower). Plus, you can add the inevitable heat loss caused by the ability to absorb and dissipate heat by the surface being treated, the temperature in the room, the proximity of the hair dryer to the heated area, the power of the air flow, etc. That is why only by experimental way it will be possible to choose the exact value of the operating temperature (thermo profile) for a particular soldering station.

Как правильно использовать термопасту для материнской платы

Давайте в первую очередь, разберемся, что же такое – правильное использование и нанесение термопасты.

Обязательное условие – слой термопасты необходимо наносить равномерно по всей площади радиатора системы охлаждения, который отводит тепло от процессора (или например, чипа видеокарты или другого).

Слой термопасты необходимо наносить тонко и равномерно. Чтобы в нем отсутствовали какие-либо пятна, или разрывы или поверхность была покрыта не полностью. Если опыта в такой работе нет, то сразу получить качественное нанесение может оказаться проблематичным.

Для замены термопасты на элементах вашего компьютера вы можете обратиться в наш сервисный центр:

Однако, если вы решили заменить термопасту самостоятельно, то читайте дальше.

Прежде всего, нам понадобится собственно, сама термопаста. Не покупайте дешевую, она быстро высохнет, экономия не стоит риска повреждения компьютера.

Любая пластиковая карта (для нанесения пасты). И найдите какую-нибудь салфетку для удаления излишков.

Далее приступаем к нанесению:

Выдавливаем из тюбика пасту от одного края до другого по поверхности процессора. После этого, взяв карточку, плотно прижимаем ее к поверхности процессора и медленно и аккуратно, одним движением размазываем ее по поверхности. Чтобы слой получился более равномерным, можно пройтись несколько раз по поверхности.

Результат обычно получается хорошим. Карточка идеально подходит для равномерного нанесения на поверхность процессора или другого чипа материнской платы.

Если вы испачкали пальцы, следите за тем, чтобы не заляпать пастой детали материнки. Это может привести к непредсказуемым последствиям. Своевременно вытирайте пальцы или другие испачканные места. В обязательном порядке необходимо удалять излишки пасты с элементов и не допускать их скапливания.

С какой периодичностью необходимо заменять термопасту?

Все зависит от того, насколько растет температура при нагрузках компьютера. Если режим температуры находится в норме, компьютер не перегревается, то пасту не нужно слишком часто менять. Однако, если его температура периодически поднимается до критической, паста подлежит замене, а компьютер – диагностике, на предмет его охлаждения, запыленности и т.д.

How to apply thermal paste

First, a couple of words about what is the correct application and what it is expressed in:

The layer should be applied evenly over the entire contact surface of the cooling system cooler with the processor (or other chip);
The layer should be, conditionally, as thin as possible;
The layer must be integral, i.e. without tears, naked spots from the paste, etc., etc.
As you understand, this can not always be achieved quickly and easily. If you do not know how;)

What will be required
To understand how to apply thermal paste properly we need nothing more, namely:

Tube with thermal paste (you can choose any, even the cheapest;
Plain plastic card (discount, credit card or some other)
Actually, the surface on which we will apply this paste (in my example it’s a processor);
Preferably a napkin or a cloth.
Now you can start the process.

How to apply thermal grease correctly – practice
We take a tube with paste and squeeze it, straight line from edge to edge, on the surface of the processor with one of its sides.

Keep in mind that you do not have to try very hard to make a thin line, but you do not need to expand it too much.

In the first case, up to the end of the processor, thermal pads can not be enough, and in the second layer it will turn out to be too thick.

Next, we take the card and tighten the edge tightly (not all, namely the edge, ie so that the card bends in your hands) to the surface of the processor behind the paste (there, as you can see from the photo above, left a little place) one movement, without losing the force of pressure, smear paste from left to right:

The result, as a rule, immediately turns out to be ideal. If not, you can either repeat the process again (after removing the thermal paste, see below), or gently trim the tears by smearing the areas nearby, or repeat the process again.

To create a more even and thin layer, you can go through the card on the surface several times.

Motherboard: what and why? – part2

Integrated (integrated motherboard) – most of its components are soldered on the board, unlike expansion cards, which are removable. The main advantage of such cards is their portability and cheaper production. The disadvantage is that if one component kryaknet, you have to change the whole board (hello laptop / netbook).
Non-integrated motherboard, – has expansion slots with some non-removable components (video card, disk controllers). The main advantage is flexibility in relation to replacement of faulty components. When the expansion card is faulty it can easily be replaced.
Note:
For more powerful mastery of the material, all further narration will be broken down into subchapters.

Form factors of the motherboard
When choosing a motherboard, you need to remember about its parameters such as form factor. This characteristic is responsible for the ability to shove the mother into the body of his iron horse. Ie, – attention !, – not every motherboard can be installed in your system unit. To avoid dancing with a file around the case and the MP, it is necessary to understand its anthropometry (dimensions). Let’s take a closer look at this.

Form factor – the linear dimensions and position of the components of the device laid by the manufacturer (in the process of designing). At the moment, there is the following classification of the main (most common) form factors.

Despite the similarity of the technological process of production, each manufacturer tries to separate and release its unique product. The main players on the “motherboard market” are: ASUS, Gigabyte, MSI, Intel, Biostar.

Now let’s look at the inside of the motherboard.

So, each of you having opened the cover of the case of your computer can make sure of the presence inside the board, securely fixed with small screws, through the pre-drilled holes. Looking at the board with a glance, we come to the conclusion that it contains:

Ports for connecting all internal components (a single socket for the processor and several slots for RAM);
Ports for fixing floppy / hard drives and optical disks using ribbon cables;
Fans and special ports for power;
Expansion slots for connecting peripheral cards (video / audio and other cards);
Ports for connecting I / O devices: monitor, printer, mouse, keyboard, speakers and network cables;
USB 2.0 / 3.0 slots.

Computer Motherboard: what and why?

Honestly, the author of these lines likes to write iron articles, because they always turn out to be rich, voluminous and very useful, however, to judge you and make you this will be further in the text.

I want to start a story with one philistine conversation between two “system makers”. So, there are some two peppers and one says: “My mother died yesterday, I took out my brains, replaced it and everything began to fly.” To the casual listener it may seem that people are carrying some kind of nonsense and call the police how can such a thing be said at all? However, after thinking, you understand that two administrators met and they talk about the motherboard, that in the common people they call the “mother”. Actually, the last, as you already understood, this article is devoted to.

Motherboard (motherboard / system board), – alpha and omega of any personal computer. It is on it are all the vital components necessary to “breathe” life into your computer. The motherboard is a skeleton, to which everything else is attached, and therefore, if it is initially shaky, then the output is “so-so man” (weak comp). Therefore, if you want to have a competitive machine for a long time, it is very important to be able to correctly choose and understand all the insides of the motherboard. This we also have to do next.

I think you are aware that the PC is a complex of many components, each with its own roles and functions. So, the mission of the motherboard is to establish interaction (dialogue) between a huge number of different computer modules. It is from her characteristics that the vitality of your iron horse depends, i.e. how long he can adequately (without lags and brakes) pull his strap.

The peculiarities of the motherboard (MP) include the fact that it:

It allows very different variations of various components (the principle of complement and interchangeability);
Supports one type of processor and several types of memory;
To work properly and together MP, enclosures and power supplies, they must be compatible.
It is also necessary to know that motherboards are, conditionally, of two kinds (although, as a rule, they have already made combos from these two for a long time)
