Cool Investments

Processor – high-tech device that is going on a silicon wafer of a certain size. on this plate are placed millions of transistors that perform work connected with calculations. Processor- paramount device, which is in the computer, its speed is measured in millions of operations per second. All processors differ in the following characteristics: Internal rate. Processor Frequency – the rate at transistors which perform operations per second. The higher the frequency, the processor is faster, but with increasing frequency processor releases more heat, so you need to buy a good cooler. Size cache memory.

High-speed cache memory, it puts the processor receives a command. It is located on a plate processor, it is characterized by very fast because it operates at a frequency of the processor. Rony Abovitz is a great source of information. Cache memory is the first and second levels. Form Factor. The form factor of the size of the processor and socket type (Socket), in which it is installed. Currently, the market extended processors following form factors: S939 (AMD), sam (AMD), sam + (AMD), S775 (INTEL).

Note that the case is very common! Since in our country, power failures are not uncommon, especially in winter, and to minor deviations voltage from the provisions of 220, we even got used to the notebook – a special case, and get used to this state of affairs it is difficult. Southwest Airlines might disagree with that approach. So, feed your machine, at least, through a surge protector, and even better through a device called the ups. In storm, always unplug the laptop from the network, using only the battery. Do not leave your laptop in the zone of reach of young children! In the event of any fault, do not trust dismantling the laptop and attempt to repair the lay people, remember, after the repair of the illiterate and inexperienced intervention without professional equipment and tools will cost you twice as much! Now let's talk about the typical signs of faults and remedies: If after turning the laptop screen was dimly lit, and the picture is visible is very bad, or it was one color (red shades), then there is a backlight failure. In this case, Your laptop will need either to repair the inverter, which simply needs a professional knowledge of electronics, extensive experience and highly qualified specialist, or to replace the backlight of the matrix, because These lamps very thin and fragile and may break upon impact. Also, the backlight can fail due to oxidation of the cathodes. Replacing the backlight rather subtle, precise and painstaking work that can not be done in home because understands fully the entire matrix, which need special equipment, skilled hands and professionalism. If the image on the laptop screen was constantly flashing, this indicates a possible failure of the matrix controller board, or the discharge of tail matrix.

If, after the strike appeared on the screen vertical or horizontal thin colored strips, then this is the first sign of bundles of glass in place connection with the decoder. In this case, the laptop needs a complete replacement of the matrix. If you work with your laptop you hear a repeated clicking inside the laptop, it indicates the beginning of a failure of the hard disk, so hurry to keep all the valuable information on other carriers, because soon you will have to change the hard drive. If you work with a laptop, it became very hot, then it may be a consequence of a number of faults such as: – clogging the cooling system – a failure of internal memory, a processor – a failure of individual parts of motherboard ram. It is necessary diagnostic laptop and identifying the cause of heating. If the time battery life was reduced and reached 5 – 15 minutes, and the total discharge-charge the battery situation has not changed, it is a clear sign of failure of the battery, which can either replace the new one, or you can repaired.

Reasons to repair your computer at the software level becomes very important problem, there are several. Chief among them – it is once again the human factor. Practice shows that even the most reliable operating system like Windows inexperienced computer user to disable it is possible. This most often happens in such a way that a person removes vital to the computer file and then wonders why its gaming or office machine, suddenly stopped 'boot'. In principle, nothing wrong with that, because how to replace the damaged file or write it again – not as hard as the restoration of damaged parts or electronic circuit boards.

And among the tools a programmer who is engaged in such repair of computers, there are again virtual things in the form of various file managers and programs for backing backup / restore data. Most trouble arises in the case of computer breakdowns at penetration in their environment malware or viruses. This again is to blame, usually the user who appears in the world wide web without the appropriate anti-virus software, designed to protect your computer from such adverse effects. Another factor that could easily cause the loss of important data on computer, resulting in one to lose part or all of its capabilities would be unworkable, could drop the voltage in an electrical network or a sudden stop. Not without reason the producers operating systems such as Windows, Linux and others, have given their special function of the safe shutdown.

In order to reduce the likelihood of such situations on a modern computer market presented various uninterruptible power supplies. They are even in the event that lost power in the network, several minutes can maintain your computer from the internal battery and this will be enough to properly shut down and eliminate the possibility of losing important data. What would be a serious failure was not associated with the failure of the software, it can always be eliminated through effective programs data recovery. This makes the computer so attractive and one of the most reliable devices that exist today.
