Website Technical audit

Technical audit – the basic stage of internal site optimization.

Website audit helps to determine the technical readiness of the site to promote and identify major errors that may interfere with the indexing and ranking of your resource by search engines.

The main points that are important to pay attention to when conducting a technical audit:

Main site mirror (are mirrors glued to www and without www to the site, which mirror is the main one). For example:
Correct handling of 404 errors If the page does not exist or has been deleted, a page with 404 errors is required. It is important to check that when accessing it, the response of the server is HTTP / 1.1 404 NotFound. Otherwise, such a page may be included in the PS index.

Canonical addresses (rel = “canonical”).

Allows you to specify the main version of the document for the search engine of a group of pages with the same content. Incorrect use may result in pages being pushed out of the index.
CNC setting on the site. “Human-understandable” URLs are used in page optimization for both usability and search engines (additional entry of keywords into URLs, highlighting in output)
Navigation through scripts. For a link to another page of the site use the tag <a>, which is true from an SEO point of view. But sometimes other technologies are used for this, in particular, Flash or JavaScript. Robots do not follow such links, so if you want the internal website optimization to bring effect, you should not use them. If this cannot be avoided, then it is worth duplicating such links using the <a> tag.

Remove broken links. No need to “spray” the page weight on materials with 404 errors and send the user / robot to non-existent urls.
Page loading speed. Slow loading of the page negatively affects the attitude of both the user and the search engine to the site. The user can leave without waiting for the full page load, and the search robot can delete or pessimize the page.
Cross-browser. To reduce the failure rate by users, it is important to understand how the pages of your site are displayed in different browsers and, if necessary, make corrections to the code.
Cloaking Using various optimization methods, as a result of which search robots and users see different content on the pages of the site. Cloaking is considered to be exclusively the “black” method of website optimization, which all search engines struggle with. One of the methods of cloaking can include the hidden text on the site.

Region of the website. To rank by geo-dependent queries, the site must be assigned a target region.
Many redirects. The use of multiple redirects is not recommended – they can be used only when it is really necessary. For redirecting users from old pages to new ones, it is better to use 301 redirects.
The lack of technical duplicate pages. Each page of the site should be accessible only by one physical address, if this is not the case – you must remove the page or close it from indexing in robots.txt. Also, the page address should not contain session identifiers, cgi-parameter lists.

Proper use of the noindex tag, the nofollow attribute. Internal optimization involves checking the correct indexing of pages and links to a resource.
Reliable hosting. The availability of the site 24×7, the hoster’s rapid response to the problem of site downtime is an important component of the promotion.
Optimization for MU (Mobil-friendly). Searching information on the Internet using smartphones is becoming common for users, so now search engines in mobile issuance prefer sites optimized for mobile devices.
Generating the correct robots.txt file.

ROBOTS.TXT – is a file in the root directory of the site containing instructions for search robots.
In the robots.txt file, you can limit the indexing of pages that should not get into search engines (for example, duplicates or search pages on a site), as well as specify the main site mirror, page speed, and the path to the site map in xml format.

If you are internally optimizing a new site, you will most likely have to create a robots.txt from scratch and place it in the root directory. It is easy to do this – just open the notepad and insert the necessary directives into it. After that, the file must be saved and uploaded to the root directory of the site.

What exactly should be in the file?
Robots.txt must have at least two directives:

User-agent: – indicates for which search engine the instructions are intended. In order to specify the instruction for all search engines at once, it is necessary to use an asterisk in the User-agent – *

Disallow: – indicates which site directory should not be indexed. For example, you can close a file or folder from indexing by specifying the following directives:

Disallow: /file.html
Disallow: / papka /

If you do not want to close the site page from indexing, then it is enough to indicate the following:

User-agent: *

Computer: what it consists of (may be useful for repair)

Computer: what it consists of (may be useful for subsequent repair)

The core of the computer is the system unit, which contains all the most important components. With their help, the computer is functioning. We list these devices – a hard disk (hard drive), a motherboard, a graphics adapter, a processor, and memory cards. The computer also includes a monitor (display), an optical mouse and a keyboard.

Let’s take a closer look at the composition and components of the computer. Knowledge of the main parts of the computer will help easier to navigate, to choose the right company that carries out computer repair in Cincinnati.

You can open the lid of the system unit and see what is included in it.

Among the abundance of components, it is easy to find a processor – this is the main brain of the computer, because it carries out all operations.

The speed of the computer is in direct proportion to the processor power. A more powerful processor provides faster performance. Although, frankly, this parameter alone will not provide the desired performance. It is much more important that the processor, RAM, hard disk and video card match each other in terms of technical characteristics – this will fully ensure the high speed and performance of the computer.

TIFU by using an air compressor to try to remove a stray blob of liquid metal that had shorted a bunch of socket pins together.

Because even the most modern processor is not able to provide outstanding performance if the other components of the computer are hopelessly outdated.

The main link is the motherboard – it provides the connection and communication among themselves of all components of the computer. It has special connectors for connecting RAM, video card, processor, as well as many other outputs, cable connections and loops. For example, to connect a monitor, keyboard, hard disk, etc. If the motherboard is damaged, it is not necessary to replace it with a new one; it is subject to repair.

The graphics adapter, or as it is called, the video card provides a high-quality image on the monitor. For applications requiring high graphics performance, it is recommended to choose a more powerful graphics card to avoid freezing or slowing down your computer. There are motherboards with integrated graphics. We do not recommend using them, since their capacity is very limited and they will definitely not be suitable for more or less intensive work.

Как очистить от пыли ноутбук

Если вы решили самостоятельно очистить от пыли и грязи клавиатуру ноутбука Asus.

Ноутбуки данной компании очень удобны в использовании, особенно их клавиатура, однако она не имеет защиты от попадания внутрь различных загрязнений и пыли. Если не уделять должного внимания своевременной очистке, то длительная работа с загрязненной клавиатурой может привести к какой-либо поломке. Это чревато дорогостоящим ремонтом сломанной детали или  полной ее заменой.

ремонт ноутбуков в могилеве

Наиболее распространенная неприятность – это подверженность клавиатуры к излишнему стиранию, проще говоря, она практически не имеет защиты от истирания поверхности. Это характерно для многих моделей ноутбуков Asus. Самый бюджетный способ устранить эту проблему – купить и нанести наклейки с буквами прямо на клавиши. Некоторые делают это сразу же, после того, как купили ноутбук.

Поскольку клавиатура не обладает достаточной степенью защиты, то под кнопки попадает пыль, грязь, крошки, которые вызывают затруднения при нажатии на кнопку, или залипание и прочие неприятные моменты. В таком случае клавиатуру нужно очищать.

В качестве средств для очистки необходимы: пылесос, мягкая тонкая кисточка и влажная салфетка. Из зазоров под клавишами пыль выметается с помощью кисточки и при этом собирается пылесосом. После того, как вся пыль будет тщательно удалена, клавиатура аккуратно прочищается влажной салфеткой. Если же степень загрязнения клавиатуры более серьезная, то это потребует разборки ноутбука.

Операцию по разборке необходимо проводить очень аккуратно, поскольку защелки, на которых держится корпус обычно хрупкие и легко ломаются.

Защелки, на которых держится клавиатура необходимо отщелкивать по очереди, постепенно приподнимая клавиатуру. Нужно быть внимательным, т.к. клавиатура удерживается с помощью шлейфа, который очень легко повредить. Также нужно осторожно снимать клавиши. Лучше всего это делать с помощью специального крючка.

После снятия клавиатура внимательно осматривается на предмет повреждений, например порванный шлейф или пролитая жидкость.

Если самостоятельно сделать диагностику клавиатуры или ремонт проблематично, вы всегда можете обратиться к услугам специалистов. Наша мастерская делает ремонт ноутбуков в Могилеве по приемлемым ценам. При этом в работе мы используем оригинальные или лицензионные комплектующие и запасные части, поэтому мы смело даем увеличенную гарантию на выполненные работы и качество деталей.

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

Как правильно использовать термопасту для ремонта 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:

«Ремонт компьютеров в Могилеве» по адресу: 212000, г. Могилёв, ул. Ленинская, 63, тел. +3759712416, адрес сайта

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

How to apply thermal paste in electronics

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

Motherboard: what and why about use and repair

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.
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)
