Clean the chassis but individual strength work, but still have to prepare cleaning appliances. A screwdriver, a brush handle, a rubber inflatable bladder, a, then you can start cleaning work.

When it comes to the chassis cleaning, first do of course is the external dust cleaning. Simply wipe it with a cloth, and then to move the screwdriver to minor operation.

Friendly reminder: if you are using a brand machine and in the warranty period, please note the packing label, so as to avoid unnecessary losses.

Open the box, you can see the card has gathered a lot of dust, some people do not know how to start. Suggest you start from the independent board, also is the independent video card ( card, sound card, computer card ) to start, as for graphics and other integrated on the main board of relaxed, start it from memory.

This method, which is not desirable

Get in by every opening of dust

Open the box won't open, you will scare you jump: motherboard, graphics card, power supply, cable, fan is covered with dust. The dust is the enemy of the normal operation of the computer, the host, will bring what harm?

You'll find out the leaf CPU fan wrapped in a thick thick dust, this makes the slow rotation of the fan, even when severe may let the fan stops rotating, is a direct consequence of CPU system temperature, frequent crashes. Look at the board surface, hands touch, a layer of ash covered in the surface of the board. For the tower, dust cross on the motherboard graphics than the motherboard for many, you can see at a glance. Some users in order to make the case better heat dissipation, like the chassis side baffle plate down, let the case where the more air circulation. This short time may flow is good, but the long-term such word, more dust into the chassis, which brings hidden trouble of large. As the largest source of power in the case, it is accompanied by a huge fan, day in and day out large amounts of air, has become one of the most easily absorbed dust. Dust into the internal power supply, will accumulate in the power supply element and the circuit board, influence the normal fan rotation, large noise, even in the heat affected cases will damage to other components in the computer.

Software

1, operating system: simple example explain: the same configuration of computer, running the original Windows 98 must be faster than the original Windows XP operation, while the original XP certainly better than running the original Windows Vista faster, which means, the same configuration, software for system resources with greater speed, more slowly, and faster.

Also, the original English edition of the operating system running the English version of the program than the procedure stability and speed of operation Chinese version are relationship.

Therefore, particular emphasis here is the original system, the system is not reduced. Similarly, to streamline the Windows XP generally speaking, than the original XP faster, because the streamline some not commonly used procedures, engrossing less system resource, so the speed has improved significantly.

2, software (hardware ) can be properly optimized, for users, such as: general office clerk, the general configuration of computer, install a streamlined version of the XP and Office Lite 2003 is enough for daily use. But if it is a graphic designer, you need professional configuration, especially on the cards required, therefore, to upgrade the software: Microsoft DirectX version 9 or above is very necessary.

Evaluation criteria

1, CPU, this mainly depends on the frequency and level two cache, the higher the frequency, the level two cache is bigger, faster, the future CPU will have a level three cache, the level Four cache etc., all influence the response speed.

2, the memory, the memory access speed depends on the interface, particle number and storage size ( including memory interface, such as: SDRAM133, DDR233, DDR2-533, DDR3-800 ), in general, the more memory, data processing ability is stronger, faster.

3, motherboard, mainly processing chip, such as: processing capacity of more than i945 chip i965, i945 than i910 chip ability in data processing and stronger, and so on.

4, the hard disk, hard disk in daily use, consider less, but also has some influence, first of all, hard drive speed (: high-speed hard disk and low speed hard disk, hard drive speed is generally used in large server, such as: 10000, 15000; low speed hard disk used in general computer, including notebook computer ), desktop computer with 7200 rpm, notebook computer with 5400 rpm, which mainly considers the power consumption and heat dissipation causes.

Hard drive speed because of different interfaces, different rates, in general, IDE and SATA ( which is often said that the serial port ) interface, the earlier disk is IDE interface, by contrast, access speed is slower than the SATA interface.

Hard disk with the development of the market, the cache rose by the previous 2M to 8M or more, like the CPU, the larger the cache, speed will be faster.
