First clean your computer manually based on off until the screen becomes completely black, then granulated completely separate electricity about him and tied him any part of the keyboard and mouse and scanner or printer, camera, and Almaekervon and other wiring.

You can use some types of products that are specifically made for a very clean your computer, through a few of them sprayed on a piece of cloth and then start scans the screen, with the caution of the use of any type of alcohol or products based on its industry in order to avoid any harm to your computer.

You should avoid using some paper towels are only to remove stains, it may disintegrate during cleaning or volatilize, including some parts. It can also mix some white vinegar with water in equal proportions and start to clean any stains or dirt is present on the computer. You should avoid igniting the computer immediately after the cleaning, so it should be left up to a period of time should be good and get rid of any moisture stuck as a result of cleaning.

The cleaning device of some internal content is up to by following some of the steps and methods such as:
Disk Cleanup Using Disk Cleanup tool (Disk cleanup) can access this tool by clicking on Start, then attached and then System Tools, Programs, and then click on the Disk Cleanup (disk cleanup) by selecting Aldreif c, then click on OK and then place tick in front of each kilo more than zero and then click on OK bytes to end the cleaning process.
Also must remove the old programs that do not need them, they occupies a large area without any benefit, and that by deleting the program files in c Drive in the Windows folder, and then to the program files (program file) and search for the program, which must be deleted.
It should get rid of the viruses cleaned by many programs like ccleaner or by pressing the Start, then search for in the search list containing the lens in the same list, write to run, then the window will run and is then written the following sentence

Computer speed

Computer speed




Computer speed
When Ntsal for computer speed we must overview of the performance of the CPU speed of the CPU is the central factor in the performance of your computer, and while a lot of people use a clock speed of the CPU to measure performance, but this is not the only variable which have to be considered when talking about the speed of the computer, such as the elements of the front side bus also play an important role in the speed of the CPU.

Clock speed
The most common of the speed of the CPU meter is the clock speed, measured Balmighardz or Agheigahertz. GHz and one equals 1,000 MHz, and so fast 2.4 GHz and can also express it by saying 2400 MHz, the higher the clock speed, the more able to perform more CPU operations per second.

It is important to realize that the clock speed of the CPU is not the only factor that determines performance, due to differences in the structure of the chip, and the processor may be able to perform more operations of another during a single session, and that, even if the first processor contains clock speed is less than the second, it may actually be faster.

Multi-core technology
Some processors are "dual-core" or "quad-core", these terms refer to the use of CPU and multiple on one circle, and the idea behind this concept is to improve processing speed, and using two or more processors that can be operated independently or cooperatively, actual advantage to the presence of a single processor is different because the software usually have work to optimize multi-core processors in order to gain a significant advantage is speed.

Front side bus and Cache
With any processor, cache and front carrier memory plays an important role in the speed of the CPU where it is working in conjunction with front side bus, so ideally should be run at the same speed so that one does not affect the other, and cause Babtaúha on the other hand, memory caching also play an important role in the speed of the processor, cache is a memory that is accessed by the CPU to assist in the completion of some routine tasks faster, so the larger the cache, the largest, it increases the performance of the CPU.
