Slow analysis of computer running speed and its solution

Most people just start to install the system, will find that the speed is very fast, but after a period of time, feel the computer running faster and slower,

Here I analyze the reason roughly, another aspect is the hardware reason, one aspect is the software reason.

Hardware-related reasons:

One, hard drive bad road

Computer long-term use, the hard disk caused by the wear will be very large, especially such as Internet cafes, such as long-term boot and non-normal shutdown of the computer, its hard disk loss will be greater, hard disk damage is generally from a small number of bad start, and then gradually the worse the larger, Also some hard drive is due to poor power supply or hard drive quality and cause the hard drive motor running speed down, that is, the hard disk board part of the damage.

We should develop good habits, do not "illegal shutdown", to allow the system to shut itself down, as far as possible to reduce the damage to the hard disk, if you are anxious to shut down, you can also use the "Fast shutdown" software, or use the "Task Manager" and then hold down the CTRL key and then point task Manager shutdown, this speed is very fast, The computer shuts down in about 2-5 seconds and does not damage the hard drive. When the hard drive has a bad way to distinguish the division, use the partitioning tool to find and separate the corresponding bad parts, do not let it continue to expand. Another hard drive if suddenly the noise is too large, it is likely to be bad omen, quickly get professional place to overhaul.

Second, the memory is too small

Today's system is very eat memory, such as XP system at least 256MB, if it is 128, it will be very card machine, and play a large game on the 512MB of memory even more, and eat more memory system is vista, System basic operation will need 512MB, If you want to run smoothly on the need for 1G of memory, playing a large game can be imagined ... No 2 G is going to be a big card.

Third, attention to heat dissipation

The summer has come, the heat has become a very important problem, we know that the computer in the CPU after the temperature rise in the hot summer CPU internal temperature is very high, CPU manufacturers to protect the CPU, the CPU temperature is too high when the automatic reduction of the frequency to not burn the CPU, the other motherboard also has high temperature protection, When the CPU temperature is too high will automatically power off, so pay attention to the CPU temperature, when the temperature is too high when the CPU will automatically change the "card machine." In the winter also should be careful not to let the computer too cold, temperature too low will lead to the machine.

To solve the heat dissipation method, regularly clean the dust inside the computer, in particular, CPU fans must be wiped, wipe the silicone, it is not good to change a more powerful fan, but some people are accustomed to open the chassis, so that the cooling effect is relatively good, but it may be injured inside the chassis, so easy not so "bright"!

So how to simply judge where the computer is stuck?

First, open "task Manager" to see whether the CPU load is too high, or the memory is all occupied.

Second, in the running of the program or the game to listen to whether the hard drive for a long time to see if the hard drive lights flashing non-stop, if the memory is too small will aggravate the hard disk burden, if the hard disk has bad block will run some programs too slow, while other programs are normal.

Third, regularly clean up the garbage files, regular anti-virus, etc., if the original system of a normal suddenly one day the system is particularly slow, it may be caused by the virus.

At the same time to develop a good habit of operating the computer, do not "illegal" shutdown, do not always put a CD-ROM or insert a U disk in the computer, regular cleaning of the internal dust inside the chassis, especially in the summer to pay attention to the problem of heat dissipation. Let our love machine always protect the optimal state, for our efforts to dedicate her youth bar!

Four, the CPU is not strong enough

Now the system and some programs are also very eat CPU, especially some large online games, in many places is very card machine, which requires that your CPU chip can not be too low, like 1 yang. X This kind of CPU is basically eliminated by the game, but now the CPU development "very speed", the dual core has been very common, the next step is a quad-core, that is, generally the CPU speed has completely exceeded our needs, Even if it is like Sai Yang 2.8D such a very classic CPU, playing a large 3D game will not be very card, if it is very card and it is possible that your video card does not keep up or your memory capacity is small, not necessarily the problem of the CPU.

Everyone in the "task Manager" can see the CPU load, look at what the program is compared to "card machine", in the end is the card in what place, to do the heart know, the future upgrade is also convenient.

Software reasons:

One, the program installs too many

A lot of people are amateurs, do not know or do not understand the installation of a large number of programs, many programs are not necessarily used, and the default installation of the program in C, most installed in C:programfiles this directory, which is quite a number of programs and games default installation directory, Rookie of course, The next step is so installed in the C disk, resulting in C disk space tension, while the other several disks are empty. There are many programs are the default for the start, such as QQ chat, QQ games, Utgame, Thunder, Internet Express and so on, the results of the boot when the system started at the same time started a lot of programs, slow to death.

Solution: In the installation program, in addition to the very important and must have the software installed in C, such as Antivirus, fire, office software such as. Other software can be installed in other partitions such as D disk, such as QQ, media Player, all kinds of game waiting, and some in the reload system can not run after the program may be installed in C, for example, some network TV must be installed in the C disk. In fact, as long as the procedure is not large, can be installed in the C disk, at the same time to see C disk space capacity, for XP system, the system itself within 3G, 5G of hard disk space is basically enough, and then decorate the program generally 8G space can be completely, if the program takes up a lot of space such as C disk used 10G space, that should pay attention to, There are too many things in the C-disk system. Also start the program to clean up, some do not need to start with the system does not let it start. In the Start menu > Program > Startup, you can delete a startup program such as QQ. Also can enter Msconfig this program in the operation, turn on the right start management, will not use the START program's tick to remove. At the same time also can be simple to find out whether there is a Trojan also randomly started. In addition, some tool software, such as Kaka and the master of Windows Optimizer, also has the option to initiate program control.

In addition, when you remove the program, do not directly delete the program directory, to remove it completely with the uninstall of the program, if there is no uninstall in the program directory, go to the Control Panel > Add Remove Program, find the program to uninstall it, and also can use some very good uninstall tools, such as the perfect uninstall.

Second, improper system setup

Some people the machine itself is good, but due to improper setting caused unnecessary trouble. For example, there are too many things on the desktop, virtual memory is too small, c disk space is not enough.

Set Virtual memory

There is a very large data interchange file on the hard drive, it is reserved for the system of virtual memory as a place, many applications are often used, so the system needs the main memory for a large number of data access, so the speed of access to this file is a very important factor in the impact of computer speeds! It will automatically adjust the size of the exchange file to fit the needs of different programs, but this narrowing will bring additional burdens to the system and slow down the operation of the system! In view of this, it is best to customize the minimum and maximum value of virtual memory, avoid the constant size of the transformation. To set virtual memory, My Computer > Properties > Advanced > Performance Settings > Performance Options Advanced > Change >

The minimum value can be set to 1.5 times times the size of the original memory when setting the virtual memory value. Set the maximum value to twice times the minimum value, if your memory is large, you can not set 1.5 times times, and for the FAT32 partition format, set a single file greater than 4G, there will be errors, so more than 4G of virtual memory to be placed in the NTFS-formatted partitions, generally about 2G of virtual memory is enough, no more than feeling fast.

Third, the virus and rogue software, etc.

The virus causes the system to slow down, which is the most common, one of the most prominent problems, because the virus is infected with your system files while searching for other programs on your hard drive, it will infect all infected programs, that is, the program files for multiple read and write operations, and the virus will also run before the program is launched, loaded into the system, Occupy a large number of resources, resulting in the system significantly slowed down, and spread the infection it people computer, there may be added Trojan elements, steal the local information, may eventually drag the system to death. The system slows down when the Trojan is infected, but relative to the virus will be better, because the Trojan is only secretly loaded into the system startup items, in addition to the system disk key files are rarely involved in other sections of the file, can also be called the spyware, steal this machine information, game number, QQ number and so on. The most annoying is rogue software (also known as adware), they and Trojans using a means of infection system, in the background to load some programs, often open some Web pages, pop-up ads window, may download the updated version of the software, leakage system information, but do not steal what game number and QQ number. In addition, some hackers have never interrupted the attack on other people's systems, and today's virus makers may also combine Trojan tools and hacker tools to create a new hybrid virus, such as panda incense virus contains Trojan elements, stealing game number.

For the above three categories of computer-endangering programs, viruses, Trojans, rogue, of course, there is a way to deal with, such as the major anti-virus software for these three categories of the production of the corresponding killing procedures, such as rising, anti-virus is killing virus and Trojan, rising firewall is to prevent hackers, rising card helper is to kill Rogue software. Many Trojan software can also be registered free of charge, free virus-killing software has foreign Norton Personal client, mccafés personal client, as well as rising and other domestic manufacturers also launched a free N-day service, in addition to online anti-virus. That means we can find lots of good software to kill the damn damage program without spending money.

As long as the user is used properly, pay more attention to it, still can shut it out. Since ancient times there is a shield, we do not fear, form a good habit, regular backup of key documents, backup good system, it can not be immediately restored. Backup system tools have dwarf dos, Maxdos, one-click Recovery Software.

Four, long-term use not finishing

There is another reason is the long-term use of not finishing, because the program is arranged on the hard disk is also in order, but the user to operate the process of frequent installation, removal of the program, resulting in the use of hard disk, fragmented files, in the reading of programs and files will consume more time. There will also be a long time to use the resulting spam file is very much, some temporary files have not been deleted will accumulate more.

Clean up and hard drive finishing is also simple, such as XP system, Start > Program > Accessories > System Tools, HDD cleanup and disk defragmentation are here. In addition to the system from the program, there are a lot of cleaning up the garbage, such as a key to clean up the garbage batch files, optimization master of the cleaning function, super free son, as well as a trace, scavenger, Nortoncleanseep (Norton Cleaning Tools) and so on
