1. Processor: As we all know, the position of the processor (CPU for short) in the computer is equivalent to the human brain, and the operation speed of the CPU affects the running speed of the whole computer. Of course, the problem of computer card and slow response is not directly related to CPU. We'll talk about this later.
Second, memory: the computer card may be the easiest to understand because the computer has insufficient memory. Why memory causes computer card and slow response is reflected in old computers. In the past, the price of memory was very high. In order to save money, the general processor is enough, and the memory capacity is reduced. One less processor is used, so the main way to upgrade is to add memory chips. During installation, less memory is used. Adding memory after upgrading improves the overall speed of the computer, so ordinary users only think that the fundamental hardware reason that affects the speed of the computer is memory. This is an illusion caused by the memory lag of computer development. It's very cheap now. 4G memory is only about 170. I remember I bought 100 at the beginning of 20081g-mtou.info).
Third, the graphics card: the phenomenon that the graphics card causes the computer card is mainly reflected in the large game users. And it is easy to cause the illusion of game users. There are two situations: in the first case, if the graphics card is large, the game performance must be good. In the second case, the game performance must be better when the graphics card and memory are large. Both of them are one-sided and ignore the relationship between processors. The same is 2g memory, but Celeron dual-core E3200 card and Pentium E5500 can't. I'm afraid X245 will perform better. Therefore, the processor is the foundation of the upgrade, and the memory and graphics card are the key to the upgrade.
Fourth, hard disk: Because of the hard disk of the computer, many people may not understand the computer card machine, because the probability is almost zero, but once this happens, it will be uncomfortable. How can I put it? For example, if you hang the IDE low-speed hard disk on the 945 motherboard and the processor uses E2200 dual-core, your processor is very fast at this time, but the reading speed of the hard disk is very slow, which restricts the display of the processor. Moreover, call the task manager, and you will find that the processor utilization fluctuates greatly. Some hard disks have bad tracks because of bumping or other reasons, which will also seriously affect the computer card machine, especially the slow boot speed, which I deeply feel.
5. Other reasons: This cannot be listed one by one, but it does exist. Why do you say that? For example, the virtual memory technology of the motherboard. If the motherboard sets aside some memory for the graphics card, your actual memory will be very small. At this time, it is the problem of motherboard BIOS settings. So the above four situations are only the most common.
Coping method
If it's a hard disk, just replace it with a high-speed hard disk. Needless to say, if you use IDE, I suggest replacing it with a SATA hard disk. If it is suggested to change the speed from 5400 to 7200, the speed of the hard disk is an important parameter to determine its response speed. If money is not a problem, use SSD solid state drive. If it is any other card, it would be a waste to add a graphics card above X240 to E 1400. To make a reasonable collocation, the principle of reasonable collocation is: processor-based, sufficient motherboard, appropriate memory, and video card to watch games. The processor must be used as well as possible, with large main frequency and secondary cache, many instruction sets and good architecture. Players suggest AMD or I3 I5 I7 series. Motherboard must be enough, not enough is not conducive to upgrading and maintenance. Memory is generally mainstream. Some people use 4G memory in this era. I can tell you responsibly that if you are an ordinary user, the full 2G memory is almost zero (if you use win7 64-bit system, it is recommended to buy 4G memory, after all, it is cheap now-Mu Tong's note). And the memory is easy to upgrade, if only the motherboard had dual-channel support. Graphics card According to the game, if it is World of Warcraft, it is recommended that the graphics card be no less than 800 yuan and the processor be no less than I5. This is the perfect configuration to run World of Warcraft. If you have enough money, you can use I3 with the graphics cards around 500 yuan, which should be very smooth and the computer will not be stuck.
The software is not powerful.
First, startup items: Because there are too many startup items in the system, computer cards are the most common. As soon as you start the computer, a large piece of software is displayed on the tray in the lower right corner, which will inevitably cause the memory to be occupied by these things, but there are many things that you may not need in a day. These occupied memories are always fixed, such as 1g memory. The default minimum for xp is about 100m, and 900m can be used to run other things, while your startup item will occupy 400M, and you still have 500M to use. You will feel stuck if you run10mQQ again, and your memory usage at this time is.
Second, the process, the process that the system must start by default may be 8, and the best running state is 14 (ordinary user). 14 processes can occupy about 100M of memory. If you install too much software or open too many system processes, such as 30 processes, and there is almost 600M left in 1G memory, how can you run other software more smoothly? You can have a look here: detailed explanation of Windows system processes, which lists the functions and common problems of various processes that are common in computers. If you find that the computer is stuck and slow to respond, choose this process and end it.
Third, compatibility, needless to say, anti-virus software is an example. Micro-point and Rising will know if they try it. Computers can't walk. This is the reason of antivirus software manufacturers. The deep-seated reasons for this situation can be seen from the war between QQ and 360.
Fourth, the virus: there are not a few people who know this. People who have been infected with the virus must have this experience. The virus will increase the CPU utilization to 100%. Can a processor that doesn't use space not be stuck?
5. Others: The system configuration file of the computer is sometimes the chief culprit of the computer card. Please read "What is the reason for the slow response and slow startup of the computer?" As stated in the article "System Profile is the Key", a user profile is as high as 3.6G, which is enough for your computer card to load. For example, too much disk fragmentation will also have a certain impact on the speed of the computer, but the impact is not too great.
Coping method
Reinstalling the system can solve the card machine and avoid upgrading the hardware, but people who can't use it often solve this problem by installing the system. Reinstalling the system can solve four problems in the software (the step flow of efficiently and quickly redoing the system). If the results are one by one, these problems can be solved by software or commands. Start menu-Run -MSConfig. After entering the operation interface, the startup tab inside can remove redundant startup items, and the service tab can close redundant processes (startup items can solve the computer card graphic tutorial). Problems caused by compatibility can be solved by uninstalling incompatible software. The virus problem is best solved by reinstalling the system. Or use a better antivirus software at ordinary times, and it is recommended to use micro-point active defense. I'm not kidding. I have tested it on a virtual machine and also tested it with virus samples. The strongest is micro-point active defense, and the second is Kaspersky. The actual antivirus rates of Rising, Jinshan and Jiang Min are not high.
Related symptoms
Finally, let me talk about the misunderstanding of the plane crash. The crash is generally only for blue screens, and automatic desktop shutdown and card removal are not crashes. The common causes of these three problems are: blue screen: mostly caused by system problems; Then there is the reason of memory, which is often caused by poor contact between memory slots and poor welding of memory particles. The rest is due to other hardware, but it is not very common. The above two situations are very common. Shutdown: There is no common reason for this. What I have experienced is that the processor temperature is too high, the hard disk is broken, the data cable of the hard disk is damaged, the virus and so on. Card crash: This situation is mostly caused by insufficient power supply and poor contact of some hardware. Of course, the system resources are full. I haven't seen many other reasons.
