Computer accessories--by function

PnP function The motherboard with PnP BIOS and PnP operating system (such as Win95) can help users to automatically configure the host peripherals, so that the plug-and-play energy-saving (green) function generally has the Energy Star logo when booting. It can automatically enter the wait and sleep states when the user does not use the host, during which the power consumption of the CPU and various components is reduced.Jumperless motherboard This is a new type of motherboard that is a further improvement of the PnP motherboard. On this kind of motherboard, even the type of CPU, working voltage, etc. do not need to use the jumper switch, they are automatically recognized, just use the software to make a slight adjustment. The Remark CPU will be invisible on this motherboard. The motherboards before 486 generally do not have the above functions. The motherboards above 586 are equipped with PnP and energy-saving functions. Some original brand machines can also control the power on/off of the host through the motherboard to further enable intelligent on/off, which is compatible with the motherboard. It is still rare, but it is definitely a development direction in the future. The jumperless motherboard will be the other direction for the development of the motherboard.

How to choose computer hardware?

When selecting hardware, you need to consider the hardware performance, you can judge by observing the hardware parameters.1. CPU: Generally speaking, the performance of the CPU is determined by its architecture, level 1 cache, level 2 cache and level 3 cache. The better the architecture, the larger the cache and the better the CPU performance. At present, the CPU is multi-core and multi-threaded. The more cores, the stronger the multi-tasking capability, but this is not absolute, but also depends on its architecture. For example, some CPUs are quad cores, but it encapsulates two cores together to form two modules. This quad-core CPU is a pseudo quad core, which can only be regarded as a dual core. In general, the strengths and weaknesses that determine the performance of the CPU are ranked as follows: Architecture > Number of Cores > Frequency > Cache.There are two main types of CPUs: Intel's CPU and AMD's CPU. CPU with the same performance, Intel's CPU price is more expensive than AMD, but AMD's CPU power control is not as good as Intel's CPU. If you don't have a lot of budget at hand, it is recommended to choose AMD's CPU. If you have a good hand, it is recommended to choose Intel's CPU. In comparison, AMD's CPU is more cost effective.2. Motherboard: The factors that determine the quality of the motherboard are mainly the chipset, the number of power supply items, the expansion capability, and the workmanship. For the motherboard, the most important thing is stability, followed by expansion capability, and its stability is generally determined by the chipset, power supply and workmanship. Generally, the more power supply items, the better the workmanship, the better the stability of the motherboard, and the expansion capability. Refers to the expansion capabilities of its interface, such as whether it supports USB3.0, whether it supports overclocking, etc. Therefore, it c

What kind of computer is right for you?

Before configuring the computer, think about what you are mainly doing with this computer. Generally speaking, there are the following types: playing games, home, office, and special professional fields (of course, enthusiasts are not in the scope of discussion). ). The performance of the computer depends mainly on the CPU and graphics card components, so you need to carefully select the CPU and graphics card.1) Household: If it is household, such as watching movies, surfing the Internet, etc., the configuration requirements will not be too high, choose an entry CPU and an entry card (of course, if you have a good hand, you can choose better. CPU and graphics card).2) Playing the game: If it is a general game, such as Warcraft, cross the FireWire, the mainstream entry CPU and entry-level graphics cards on the market (referring to the CPU and graphics cards produced after 2009) can cope; Is a game with more special effects, such as World of Warcraft, Musketeers love this large-scale online game, you need to choose a slightly better performance graphics card, it is best to choose a mid-end graphics card can handle; if you want to play some large Single-player games, the requirements for graphics cards are particularly high, and there are certain requirements for the CPU. It is recommended to choose a medium-end or high-end graphics card and a good CPU, otherwise it will be easy to happen when playing some games. Therefore, in general, if the main purpose is to play games, it is recommended to have a slightly better graphics card. If you have a good hand, you can consider choosing a CPU with good performance.3) Office: For office use, it is often necessary to switch between multi-tasking, so it is best to choose a CPU with multi-threading capability, so that you will feel a lot of computer fluency when you are in the office.4) Special professional field: If special fields are used in special fields, such as engineering drawing or graphic rendering, the performance requ

What should I do if my desktop computer cannot be turned on?

The power is not turned on. After the external power is turned on, press the power button of the host, the power button light does not light, and all the lights on the front panel do not light.How to troubleshoot the problem that the desktop computer cannot be turned on:1. Check if the external power environment is normal and whether other electrical appliances are used normally.2. If the external power supply environment is normal, re-plug the host power cord or switch to the monitor's power cord test.3. Check if the power indicator on the back of the chassis is lit. If the power indicator on the back of the chassis does not illuminate, there is a problem with the power supply. Some models do not have a power indicator light behind them.4. If the power light on the back of the chassis is lit, check whether the optical drive can be ejected. After pressing the power button, there is a fan rotation inside the model. If possible, it is recommended to open the front panel of the chassis and press the power button inside the chassis to turn it on. If it can be turned on, it is a front panel problem. Conversely, it is usually necessary to replace the power supply and the motherboard.   Precautions:1) The problem of the power button on the front of the individual model will easily lead to the computer not being powered on, especially the old computer.2) The red power option on the back of the chassis is factory-selected to 230V by default. Please do not manually change to 115V, otherwise it will burn the power, no warranty.

​Basic maintenance of desktop computers

The first aspect starts with a central processing unit and a fan. The central processing unit is referred to as the CPU, and the central processing fan is referred to as the CPU fan. The CPU is the brain of the computer. All the program commands are issued by it. Besides, the CPU fan is used to cool the CPU. Understanding the above content is very helpful for everyone to maintain the computer, how can we maintain the CPU and the fan? It must be in the following two directions: The first direction is the CPU. Due to the special status of the CPU, we pay attention to cleaning the CPU socket frequently to ensure the normal operation of the CPU. Then someone will ask, cooling the CPU is the most important, is this correct? I said it was right, but only half right. The other half is the CPU fan in the other direction of my product, it is the tool to cool the CPU. To maintain this tool, you must pay attention to two: 1 to clean it, 2 must regularly lubricate the fan.The second aspect starts with the motherboard, which is the internal organs of the computer, and all other components are connected to it. How can I better maintain it? It must be from two directions: the first direction is to make it sanitary, in order to ensure the normal operation of the motherboard. The second direction is to pay attention to high voltage, do not damage it.The third aspect starts with memory. Memory is dirty on the computer, and all program commands are relayed by it. How can I better maintain it? It must be noted that a problem with the memory can cause the computer to fail to power on. First analyze the phenomenon that can not be turned on is the computer appears short call can not boot according to the above phenomenon to talk about a solution: the computer can not boot if there is a short call. The solution is to open the main box, unplug the memory, and plug it in again. If it is ok, the problem will be solved. If it is not good, the memory may be broken.The fourth aspect starts with
