How to solve the slow speed of computer

The computer takes a period of time, the reaction speed reading will be very slow, can try to solve the problem that the computer reacts slowly from the following several aspects


One, software article


1, set virtual memory


hard disk has a very large data exchange file, 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! General Windows default to the system to manage the virtual memory, it will be required by different programs to automatically adjust the size of the exchange file, but such a large scale will bring additional burden to the system, so that the system operation slowed! In view of this, the user is best to customize the minimum and maximum virtual memory, avoid the constant size of the transformation. To set virtual memory, right-click My Computer to select Properties, and in the advanced option, in the Performance dialog box, set the virtual memory.


3, check application software or driver


Some programs slow down the system when the computer system starts. If this is the cause, we can start in safe mode. Because this is the original boot, Safe mode runs slower than if it is running normally. However, if you start with Safe mode and find that your computer starts faster than it normally does, it is possible that a program is causing the system to start slowing down.


4, desktop icons too much will make trouble

Having too many icons on the
desktop also lowers the system's boot speed. Each time Windows starts and displays the desktop, it needs to look up the icons of the desktop shortcuts and load them individually, and the more icons, the more time it takes. At the same time some anti-virus software provides the system to start scanning function, which will cost a lot of time, in fact, if you have turned on the anti-virus software real-time monitoring function, then the start of the scanning system will appear a bit superfluous, or this feature is prohibited! We recommend that you put the desktop icons that are not commonly used in a special folder or simply delete them! Www.3lian.com


5, ADSL-induced system startup slows down


By default, when Windows XP starts, the network device such as the NIC will be self-test, and if the IP address of the NIC is found to be configured, it may be the real reason for the system to start slowing down. At this point we can open the Local Area Connection property menu and double-click Internet Protocol in the general item to open the TCP/IP Properties menu. Configure the IP address of the network adapter to a value that has not been used in the public network (the default gateway is 192.168.1.1), such as 192.168.1.x,x between 2~255, the subnet mask set to 255.255.255.0, and default gateway and DNS for default settings.


6, the effect of font on speed


Although Microsoft claims that Windows operating systems can install 1000~1500 fonts, there are problems when you install more than 500 fonts, such as: Fonts disappear from the application's font list and Windows ' startup speed drops dramatically. It is advisable to remove any fonts that are not used or not used in this recommendation, so that you can make the necessary backups first to avoid accidental deletion.


7, remove the random boot program


What is a random startup program? The random Start program is the program that is loaded at boot time. The random Start program not only slows down the boot speed, and faster consumption of computer resources and memory, in general, if you want to remove the random start program, you can go to the "Start" list to remove, but if you want to detail, such as QQ, Popkiller, such as software, is not in the "launch" list to delete, to go " Affiliate application, "and then go to System Tools," go to "system Information", go in, press the "tool" of the above tool column, press "System Configuration Edit Program", go in, in "Start" dialog box, will list the random start program that loads when starting a computer in detail! XP system you can also in the "run" is input msconfig call the System Configuration Utility to terminate the system random Boot program, 2000 system needs to copy the Msconfig program from XP.


8, remove background and close Activedesktop


I do not know whether we have noticed that we always placed on the desktop on the beautiful background, in fact, is very wasteful of computer resources! Not only that, but also slow down the computer in the execution of the application speed! Want to beautify the desktop, but slow down the speed of the computer, so we need to not use the background, on the desktop, press the right mouse button, then the content, and then in the Background dialog box, select None, in the "Appearance" dialog box, in the desktop preset green, black ... As for closing activedesktop, that is to tell you to close the Web screen from the desktop, such as the right mouse button on the desktop, and then the content, and then in the "Background" dialog box, there is a background, called Windows XX, that is the Web screen! So how to configure the system does not open.


10, get Windows slimmer


compared to DOS systems, Windows is too large, and as you do every day, installing new software, loading the runtime, adding new games, and so on makes it larger, and more importantly, not just its directory, but also its registry and runtime library. Because even if a program is deleted, the DLL file it uses will still exist, and as the days go on, Windows starts and exits with DLL dynamic-link libraries that need to be loaded, and the natural system is running slower and faster. Then we need to use some of the programs that completely remove the DLLs, which can restore windows to a slim figure. It is useful to recommend that the best players reinstall Windows every two months.


11, change the system boot time


Although you already know how to add and remove some random startup programs, do you know what the computer is doing during the boot up to the time that you entered Windows? Or, what program is being executed? Those programs, must be all loaded before starting into Windows, have you ever thought, if you can remove some unnecessary boot when the program, the speed will be faster when the boot? The answer is YES! Want to modify, you can press "Start", select "Execute", and then type Win.ini, open, you can delete the contents of the following paragraphs, is deleted content, do not even delete the title! They include: [Compatibility], [compatibility32], [imecompatibility], [compatibility95], [modulecompatibility], and [embedding].


second, hardware chapter


1. Windows system shuts down hard disk DMA mode

DMA mode for
hard disk you should all know that the hard disk pata mode has DMA33, DMA66, DMA100 and DMA133, the latest SATA-150 are out! Generally speaking, most people now use the PATA mode hard disk, the hard drive uses DMA mode to transfer faster than the previous PIO mode 2~8 times. The function of DMA mode plays a substantial role in the performance of the system. But you know what? Windows 2000, XP, and 2003 systems sometimes turn off DMA mode on the hard drive and automatically use PIO mode instead! This causes a sudden drop in the performance of the hard drive in the use of the above system one of the most obvious phenomena are: The system start speed is obviously slow, generally speaking, the normal Windows XP system startup when the left and right movement of the slider to go 2~4 system can start, but this problem occurs when it may go 5~8 times or more! And in the operation of the system when the hard disk operation obviously slowed down, in the running of some large software CPU occupancy rate is often up to 100% to produce a pause, playing some large 3D game when the screen has a significant pause, the above problems when everyone should look at their own hard disk DMA mode is not by Windows The system shuts itself down. To see if your system turns on DMA mode:


A. Double-click Administrative Tools, and then double-click Computer Management;


B. Click System Tools, and then click Device Manager;


c. Expand the IDE ATA/ATAPI controller node;


D. Double-click your primary IDE controller;


2, the CPU and fan are functioning properly and are adequate for refrigeration


when the CPU fan speed slows, the CPU itself will increase the temperature, in order to protect the security of the CPU, the CPU will automatically reduce the operating frequency, which causes the computer to run slowly. There are two methods to detect the temperature of the CPU. You can use the finger method to try the processor temperature is hot, but note that this method must first unplug the power, and then a grounding wire to prevent the body with the electrostatic breakdown of the CPU and damage. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.


because the type and model of the processor are different, the reasonable temperature varies. But overall, the temperature should be below 110 degrees. If you find that the processor's test is above this temperature, check to see if the fan in the chassis is working properly.


3, USB and scanner caused by the impact of


because Windows starts to detect individual drives, including optical drives, if the CD is placed in the CD drive, the computer's startup time is prolonged. So if the computer has installed scanners and other devices, or when the USB hard drive has been connected at startup, try disconnecting them first to see if the startup speed is changing. Generally speaking, because the USB interface speed is slow, so the corresponding device will have a more obvious impact on the computer startup speed, should try to connect the USB device after starting. If you do not have a USB device, it is recommended that the USB feature be turned off directly in the BIOS settings.


4, whether disk compression is used


because "disk compression" may cause computer performance to drop dramatically, resulting in slower system speed. So then you should check whether the use of "disk compression", the specific action is in the "My Computer" right click, from the pop-up menu select the "Properties" option to examine the drive properties.


5, the impact of network card


as long as the setup is improper, the network card will also significantly affect the system start speed, your computer if connected to the LAN, install the NIC driver, the system will automatically obtain the IP address by default, but most of the company's LAN does not have a DHCP server, so if the user is set to " Automatic access to IP address, the system will continue to search the network on the DHCP server, until the IP address or timeout, natural impact on the start time, so the local area network users better for their own computer to specify a fixed IP address.


6, folder and Printer Sharing


installed the Windows XP Professional version of the computer will also appear very slow to start, sometimes the system seems to give people the feeling of panic, login system, the desktop does not appear, the computer is like stop reaction, 1 minutes before normal use. This is due to the use of the Bootvis.exe program, where the Mrxsmb.dll file for computer startup added 67 seconds!


to solve this problem, as long as you stop sharing folders and printers: select start → settings → network and dial-up connections, right-click Local Area Connection, select Properties, and in an open window, cancel the file and printer sharing for Microsoft network under this connection using the following selected components check box before restarting the computer.


7, improper configuration of system fittings


Some users often neglect some small things when assembling the machine, thus causing improper collocation of the whole computer accessories, and there is a bottleneck on the speed. For example, some friends choose the CPU grade is very high, but the sound card, etc. but bought a common bargain, in fact, this is often the loss of the candle. Because of this computer in the game, video playback because the sound card occupies a high CPU resources and its data transmission speed is slow, or it has no hardware decoding and need to use software decoding method, often cause sound pause, even cause the operation of the program intermittent. And as some of my friends ' machines were upgraded, in the past, some parts of the old machine such as memory will not be discarded, installed in the new machine, but due to the speed of the old memory limit, often make the new machine must reduce the speed to accommodate it, thereby reducing the performance of the whole machine, greatly affecting the overall speed of operation.


9, disconnected network drive


to eliminate or reduce the number of network connections that Windows must re-establish, it is recommended that you disconnect some network drives that you do not need to use, that is, go to my Computer, right-click a network drive that has been mapped, and choose Disconnect.


10, missing enough memory

One of the advantages of the
Windows operating system is that it is more linear and multitasking, and the system can use the CPU for time-sharing, so that you do a lot of things at the same time. But things are good for nature, and multitasking can be a higher requirement for your machine. Friends know that even one of the most commonly used word software requires a good 16MB of memory, while running large software such as 3D Max, 64MB of memory is not enough. So at this time the system will automatically use hard disk space to virtual main memory, for running programs and storing Exchange files and various temporary files. Because the hard disk is a mechanical structure, and memory is an electronic structure, the speed between them varies by several orders of magnitude, so the use of hard disk to virtual main memory will cause the program to run a significant reduction in speed.


11, insufficient hard disk space


One of the drawbacks of using Windows System platform is that the management of the file is not clear, you sometimes do not know whether the file is useful to the system, so the number of files in the Windows directory is more and more, the capacity is more and more large, and now the software is like to do more and more, Plus some system-generated temporary files, swap files, all of which will make the hard disk free space. When the free space of the hard disk is small to a certain extent, it will cause the system Exchange files, temporary files lack of available space, reduce the operating efficiency of the system. More importantly, because we usually store on the hard drive frequently, the removal of various software makes the free space of the hard disk fragmented, so the system often does not store files in sequential order, which causes the system to frequently move the head when storing and reading files, greatly reducing the system's running speed.


12, hard disk partition too much is also wrong


If your Windows 2000 is not upgraded to SP3 or SP4, and too many partitions are defined, it can also cause the startup to become lengthy or even suspended. Therefore, it is recommended to upgrade the latest SP4, and it is best not to have too many areas for hard drives. Because Windows must mount each partition when it starts, the total amount of time to complete this operation increases as the number of partitions increases.


three, virus article


If your computer is infected with a virus, the system slows down considerably. After the virus invaded, first occupy the memory of this stronghold, and then as a base in memory began to replicate themselves endlessly, as it became more and more large, quickly occupied the system a lot of memory, resulting in the normal program running because of the lack of main memory and slow, or even start At the same time, the virus program will force the CPU to switch to useless garbage programs, so that the system is always busy, thus affecting the normal operation of the program, resulting in slow computer speed.
