Cleaning personal computer components
On numerous forums with surprising constancy there are branches in which the interlocutors try to understand the causes of failures in laptops and personal computers. As a rule, we are talking about “freezes” of the system during the operation of three-dimensional applications and random reboots. Surprisingly, in most cases, the cause of what is happening is not the actions of viruses or malicious hackers, but the banal ignorance by the owners of recommendations on the operation of computer systems. It should be remembered that any equipment needs periodic maintenance. So, you need to wipe the TV screen, wash and defrost the refrigerator, and clean computers and laptops from dust. In computer technology, ignoring this leads to malfunctions, breakdowns and subsequent repairs. Continue reading
One of the most important components of your computer is the motherboard. However, her name speaks for itself. After all, it depends on it what equipment you can install on your personal computer. The motherboard not only interconnects all other parts of the computer, but also coordinates their work and distributes the electricity that is supplied to it from the power supply. Now a few words about what the motherboard consists of.
The first and most important component can definitely be called a chipset. It is a complex of microcircuits and determines the configuration of the computer as a whole. However, the chipset is present in any technology that uses electronics.
The chipset itself consists of south and north bridges. The North Bridge is responsible for the operation of the processor, RAM and video card. For all other resources (hard drives, network card, USB ports, etc., etc.) the south Continue reading
Laptops have long ceased to be inferior to personal computers. If you want to buy a laptop, it is better to immediately think about what purpose it will be used. This purchase is not cheap, so it’s better to immediately get decent equipment.
Choose a laptop according to the parameters should be guided by some rules. You need to start from the monitor. There is a stereotype that a laptop is not able to give an image of such high quality as on a PC. However, these are only rumors.

Some people prefer to buy already-equipped models in stores, thinking that the specialists in them have already thought out all the nuances in advance. In fact, this is not always the case. After the purchase and the start of use, the consumer may find that this technique does not meet its individual requirements. In addition, it may happen that after a while the programs or components of the computer simply fail.
In the price lists of finished computers, usually only their main characteristics are given: the type and frequency of the processor, RAM, hard disk and video card. Often there is no information about the component manufacturer, sometimes only the processor characteristics are indicated, and the numbers in the price list about the motherboard, case and power supply will not tell much to people who are not very knowledgeable.

PC noise often interferes with collecting thoughts, annoying – especially in the absence of other sources of noise. To the credit of PC manufacturers, it should be noted that the best of them take into account acoustics when designing systems. However, too many PCs are still built on low-cost cooling components that create noise sources.
The main sources of noise in a computer are motors and rotating parts, such as a hard drive, chassis, processor, and power supply cooling fans. Especially the last two make a lot of noise. In addition, fans and hard drives are a source of vibration, the noise from which is amplified by the housing design and the surface on which the devices are installed. Continue reading
