Computers and Electronic Devices

Computer, as well as any electronic device can operate without any user intervention or specialist. And really, nobody did not occur to carry out maintenance tv or tape recorder. However, the computer has one peculiarity – it is high heat components of the system unit. And considering that all the components are assembled in one enclosed space – the system unit, the absence of efficient cooling can lead to overheating and fire system unit. Therefore, the cooling system components of the system unit is the "Achilles heel" of modern computers.

Consider the details of which is the cooling system on your computer. In most cases, a set of radiators and fans. Radiator removes heat from the electronic component and having a large area of contact with the surrounding air by a large number of thin edges, giving the allotted warm the surrounding air, which has usually a lower temperature. Fans need to improve air circulation around the radiator, as in a closed system block the natural air circulation is absent, and a hot radiator air does not go the natural way. The list of components of the system unit, requiring forced enough large: 1. Processor 2. North and south bridge mainboard 3. The graphic chip card 4.

Power supply in each of these components is the radiator, and some still a fan. And the whole cooling system is the system unit is working properly as long as the inside does not show up the dust. Dust – it is the worst enemy of your computer. The dust settles on the edges of the radiator and prevents heat transfer between the radiator and the ambient air. Dust clogs the space between the ribs radiator and prevents the passage of air. She settles on the fan blades, which leads to a violation of balancing the impeller and, consequently, an increased level of noise at the fan and malfunction its bearings. All this leads to a deterioration and eventually to the common "freeze" the computer, spontaneous blackouts and can even cause a fire. How do deal with dust in the computer system unit? First and foremost – is prevention. Computer system unit must be kept in a clean, well-ventilated place. Regularly every three or four months to open the system unit side cover and hold surface cleaning with a vacuum cleaner with a plastic nozzle. But if prevention does not help and the whole system unit are clogged with dust, it is necessary to carry out a full cleaning of the system unit. This procedure is best left to specialist. But if you're confident in our abilities, then step by step instructions for complete cleaning system unit from dust with photos is available on our website.

Service Providers

In the market of computer services in our city clear excess of the performers. Offers quickly with high quality and almost free of charge to solve all the problems with the computer coming from all sides. Is this possible in reality? There are two ways to provide computer help. First. The promise of free diagnosis, a very low price (say to reinstall Windows from 350 rubles) and other attractive terms. But no gift will not work. What are their benefits? Narrate how actually happening. After this work it appears that it is necessary for normal functioning of the computer to install many programs do not naturally free.

As a result, price becomes a factor of 3-5 thousand rubles. Usually quality of work leaves much to be desired – why? It's very simple – these are like "firm" master long , the average term of a specialist and a half months. He gets at best 10-20% of the cost work performed and that anything should earn at least – he was rushing to make as many orders as possible and more responsive service, as you know, it does not increase. Use the services of these, it is not honest craftsmen, not recommended. To recognize them is not difficult. This promises a very low cost, mass advertising, calendars, by the metro, the lack of intelligible dialogue on the phone, etc. Usually, these firms are not re-apply, but it is not concerned. All times are new gullible person not familiar with this method of "work".

The second method works in practice is much rarer. Its use some 'right company' and private-sector computer wizard. A distinctive feature is a reasonable price, quality guarantee for work performed and the personal approach. Professional on the phone beforehand determine the approximate cost of the work and the figure subsequently increased several times. Reasonable to date figure is 1500-2500 rubles for a complete reinstallation vindouz example. Or 500 rubles for preventive cleaning of the unit from dust, with complete disassembly and replacing the thermal paste under the heatsink. And work should include absolutely everything necessary for normal functioning of the computer. A specialist in this scheme teaches up to 75% and has no more than 2 calls per day, promotes high quality service. Customers with such masters pstoyanno work and recommend them to others. I hope that armed with this information you will be careful and do not suffer from poor service. I wish you make the right choice!
