Why is my computer very card? What should I do if my computer is slow? Cause and Solution

Are you bothered by a computer card? As a caring computer technician, I feel obligated to provide detailed and comprehensive answers to the causes and solutions of computer cards, slow operation, and completely eliminate the troubles of how to do computer cards. First of all, computers can realize the functions of multimedia, and there are two major categories of hardware and software. So we start from this aspect to explain the common reasons for computer cards and some of the rare reasons: hardware processor, memory, graphics card, hard disk, etc., software startup items, processes, compatibility and viruses. For more intuitive so that we understand, made a picture:

hardware is not to force

First, the processor: As we all know, the processor (referred to as CUP) position in the computer rather In the human brain, the computing speed of the CPU affects the speed of the entire computer. Of course, the reason for the computer card is not directly related to the CPU. I will talk about this later.

Second, memory: computer memory is not enough to cause the computer card may be the most easy to understand, why say so, the memory caused by the computer card is understood by everyone is reflected in the previous classic machine. In the past, the memory price was very high. In general, the processor was enough to save money, and the memory capacity was reduced. One less processor and only one processor, so the upgrade often uses memory sticks as the main method, and the memory is less when installed. Use, after adding memory to upgrade, the overall speed of the computer has increased, so ordinary users only think that the fundamental hardware cause that affects the speed of the computer is memory. This is the illusion caused by the computer's development of memory lag. (It's very cheap now, 4G memory is only about 170, remember that I spent more than 100 &mdash in 1G at the beginning of 2008; — MTOOU.INFO Mu Tong Note)

Third, the graphics card: the graphics card leads to the computer card The phenomenon is mainly reflected in the large game users. And it is easy to cause the illusion of the game user, there are two situations: In the first case, the graphics card has a good game performance. In the second case, the graphics card and memory are large and the game performance is good. Both are one-sided and ignore the processor relationship. The same is 2g memory, but the Celeron dual-core E3200 card, but the Pentium E5500 will not card, switch to X245 I am afraid the performance will be better. So the processor is the basis for the upgrade, memory and graphics are the key to the upgrade. Expansion: What do you want to buy a video card? What to pay attention to

Fourth, hard disk: Due to the computer hard disk, the computer card machine may not be understood by many people, because this probability is almost zero, but once this happens, it will be uncomfortable. How to say it, for example, if you use the IDE low-speed hard drive to hang on the 945 motherboard, the processor uses the E2200 dual-core, this time your processor processing speed is very fast, but the hard disk read speed is very slow, this restricts The processor is playing. Also, by calling Task Manager you will find that processor usage is very volatile. (Some hard drives have bad sectors due to bumps or other causes, which can seriously affect the computer card machine, especially in terms of booting. I am deeply touched by this. ——MTOOU.INFO Mu Tong Note)< Br>

V. Other reasons: This cannot be enumerated one by one, but it does exist. Why do you say this, for example, a technology of virtual memory on the motherboard, if the motherboard draws a portion of the memory for the graphics card, then your actual memory is small, this time is the motherboard BIOS settings. So the above four situations are only the most common. (Extension: How to maintain the notebook in the summer)

How to deal with it

If it is a hard disk to replace a high-speed hard disk, this does not say (if you are using an IDE, I suggest to change to SATA Hard disk. If it is recommended to change the speed of 5400 to 7200, the speed of the hard disk determines the important parameters of the reaction speed. If the money is not a problem, then use SSD solid state hard disk — — Mu Tong Note). If it is another card, it is necessary to consider the E1400 plus a X240 or more graphics card. To be reasonably matched, the principle of reasonable matching is: the processor is based, the motherboard is sufficient, the memory is suitable, and the video card is used to watch the game. The processor must be used as much as possible, the main frequency and the second level cache are large, the instruction set is supported, and the architecture is good. The player suggested AMD or the I3 I5 I7 series. The motherboard must be sufficient, not enough for the upgrade and maintenance. Memory is generally mainstream, some people use 4G memory in this era, I can tell you that if you are an ordinary user, your memory can be almost zero when using 2G (if you are using win7 64-bit system, It is recommended to buy 4G of memory, after all, the price is now cheap — — Mu Tong Note). And the memory is easy to upgrade, if the motherboard has dual channel support, just fine. 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 is not lower than I5. This is the perfect configuration of World of Warcraft. If it is silver, then I3 with a graphics card of about 500 yuan, it should be very smooth, the computer will not be card. Software does not give force

First, the startup item: Because the system startup item is too much, the computer card is the most seen. A large piece of software in the lower right corner of the boot is displayed on the tray, which will inevitably cause the memory to be occupied by these things. But there are a lot of these things that you might not use in a day. These occupied memory has been about fixed, such as 1g memory, xp default can be about 100m, 900m can be used to run other things, and your startup item will take 400M, you have 500M Can be used, you will run the 10 QQ you will feel the card, and at this time, your memory usage is more than 1000m, basically full. Second, the process, the system must be open by default, the number of processes may be eight, the best operating state of 14 (ordinary users). 14 processes can account for about 100M of memory. If your software is installed more, or the system process is open, for example, 30 processes, 1G memory is almost no more than 600M, how to run other software more smoothly? ? ? ?

Third, compatibility, not to mention, anti-virus software is an example, micro-point and Rising try to know. The computer can't move. This is the reason for anti-virus software vendors. The deep reason for this situation can be seen from the war between QQ and 360.

IV. Virus: This person who knows is not a minority. People who have had a virus must have this experience. The virus will use the CPU up to 100%. Can the processor without space use the card? ? ? ?

V. Others: The computer's system configuration file is sometimes the culprit of the computer card. A user profile is up to 3.6G, so the load time is enough for your computer card. For example, too much disk fragmentation will have a certain impact on the speed of the computer, but the impact is not too great.

How to deal with it

Reinstalling the system can solve the card machine and avoid upgrading the hardware, but people who don't use it often solve the problem by installing the system. Reinstalling the system can solve four problems in the software. If you end up one by one, you can solve these problems through software or commands. Start menu & mdash; - run & mdash; & ndash; msconfig, after entering the operation interface, the startup tab inside can remove the extra startup items, the service label can close the redundant process. Problems caused by compatibility can be solved by uninstalling incompatible software. The virus problem is best to reinstall the system to solve. Or usually use a good anti-virus software, it is recommended to use micro-point active defense, I am not talking about playing, I tested it in the virtual machine, using the virus sample test, the strongest is the micro-point active defense, the second In order to count Kaspersky, the actual antivirus rate of Rising, Jinshan and Jiangmin is not high.

Related symptoms

Finally, let me talk about the misunderstanding of the crash. The crash is generally only for the blue screen. The automatic shutdown and the card drop are not dead. Common causes of these three problems: blue screen: most of them are system problems causing instability; then the reason of memory, memory is often caused by poor contact of memory slots and poor soldering of memory particles; the rest is other hardware The reason, but not very common, is very common in both cases. Shutdown: This is not a very common reason, I have experienced processor temperature is too high, hard disk bad sectors, hard drive data line damage, viruses and so on. Card crash: This situation is mostly caused by insufficient power supply and poor contact of some hardware. Of course, there is also a full system resource. Other reasons have not been seen.
