How is the computer getting slower? Teach you how to deal with it from two aspects: hardware and software!

Everyone wants the computer to immediately enter the Windows system without waiting, or the system will not get slower and slower, but these aspirations are often unable to be fulfilled for various reasons, even when the server crashes or is used, it is getting slower and slower. In fact, sometimes the slow startup speed of windows is not a problem, but caused by some devices or software. This article analyzes the reasons for slow system speed in three aspects: software, hardware, and viruses, and provides system Acceleration Techniques.

 

I. Software

 

1. Set virtual memory

 

There is a big data exchange file in the hard disk, which is reserved by the system for the virtual memory for temporary storage, and is often used by many applications, therefore, the system often needs to perform a large amount of data access to the primary storage. Therefore, the speed of accessing this file constitutes a very important factor affecting the speed of the computer! In Windows, virtual memory is automatically managed by the system, which automatically adjusts the size of swap files based on the needs of different programs. However, increasing or downgrading this will cause additional burden on the system, this slows down system operations! As you can see, it is recommended that you customize the minimum and maximum values of the virtual memory to avoid frequent resizing. To set the virtual memory, right-click "my computer" and select "properties". In the "performance" dialog box in the "advanced" option, set "Virtual Memory.

2. Permanently delete the program

 

We all know that if you want to delete some programs, you can perform operations in "Add/delete programs", but you do not know that it will only help you delete programs, but will not help you delete the registration code of the program and some login projects? To completely delete the program, find some "professional" software to delete it! The nortonuninstall produced by Symantec has stopped selling some software because it has damaged the copyright of some deleted software. Therefore, Symantec has made cleansweep, but in terms of functionality, or nortonuninstall is a better chance! To put it bluntly, in addition to the two software, there are many similar software that can effectively Delete the program.

 

3. Check the application software or driver

 

Some programs will slow down the system when the computer system starts up. If this is the reason, we can start it in "security mode. Because this is the original startup, "safe mode" is slower than normal running. However, if you use "safe mode" to start and find that the computer starts faster than normal, a program may be the cause of slow system startup.

 

4. Too many desktop icons

 

Too many icons on the desktop can reduce the system startup speed. Every Time Windows starts and displays the desktop, you need to find and load the Desktop shortcuts one by one. The more icons, the more time it takes. At the same time, some anti-virus software provides the system startup scanning function, which will take a lot of time. In fact, if you have enabled the real-time monitoring function of anti-virus software, scanning the system at startup seems redundant. disable this function! We recommend that you put unused desktop icons in a dedicated folder or simply delete them!

 

5. Slow system startup caused by ADSL

 

By default, Windows XP performs a self-check on network devices such as the NIC when it is started. If the nic ip address is not configured properly, it is set, this may be the real cause of slow system startup. In this case, you can open the "local connection" attribute menu and double-click "Internet Protocol" in the "General" item to open the "TCP/IP attribute" menu. Configure the IP address of the network adapter as an unused value in the public network (the default gateway is 192.168.1.1), for example, 192.168.1.x. The value of X is between 2 and 2 ~ The value between 255 and the subnet mask is set to 255.255.255.0. The default gateway and DNS can be set by default.

6. Influence of fonts on speed

 

Although Microsoft claims that the Windows operating system can install 1000 ~ 1500 types of fonts, but in fact, when you install more than 500 types of fonts, problems will occur, such as: the font disappears from the application's font list and the Windows Startup speed is greatly reduced. We recommend that you delete unused or infrequently used fonts. To avoid unexpected deletion, perform necessary backup first.

 

7. Delete the random Startup Program

 

What is a random Startup Program? A random Start Program is a program loaded at startup. The random Start program not only slows down the boot speed, but also consumes computer resources and memory more quickly. Generally, if you want to delete the random Start program, you can delete it in the "Start" list, if you want more details, such as QQ, popkiller, and other software, you cannot delete them in the "launch" list. You need to "affiliated Applications" and then "System Tools ", go to "system information", click "Tools" in the tool column above, and then click "System Configuration editing program". Then, in the "Start" dialog box, the random boot program loaded when the computer is started will be listed in detail! In the XP system, you can also enter msconfig to call the System Configuration Utility to terminate the system random Startup Program. 2000 the system needs to copy the msconfig program from XP.

 

8. Cancel background and disable activedesktop

 

I wonder if you have noticed that we have always placed beautiful backgrounds on the desktop, which is a waste of computer resources! Not only that, but it also slows down the speed at which the computer executes applications! We wanted to beautify the desktop, but slowed down the speed of the computer, so we don't need to use the background anymore. The method is: Right-click the desktop and then press the content, then, in the "background" dialog box, select "NONE". In the "appearance" dialog box, change the default "green" to "Black ...... to close activedesktop, you can close the Web screen from the desktop. For example, right-click the desktop and then press the content. Then, in the "background" dialog box, there is a background, the name is Windows XX, which is a Web screen! Therefore, do not enable this function if the system configuration is not high.

9. Kingsoft drug overlord upgrade can also cause system slowdown

 

If you find that the system speed is slow and the Pu usage is high after you upgrade Kingsoft drug overlord, this problem may be caused by the drug overlord upgrade file. If a friend has this problem after the upgrade, first, go to the installation directory of the drug overlord and find kaextend. DAT file, delete it, and then click "tools/online upgrades" to update kaextend online. DAT file, and then restart the computer to solve this problem.

 

10. Make windows slim

 

Compared with the dossystem, Windows is too large, and it becomes larger as you install new software, load the Runtime Library, and add new games every day, more importantly, it is not only its directory, but also its registry and Runtime Library. Because even if a program is deleted, the DLL file used by the program still exists. Therefore, as the program is used for a long time, the DLL dynamic link library files to be loaded during Windows Startup and exit become larger and larger, the running speed of natural systems is getting slower and slower. In this case, we need to use some programs that completely delete the DLL to restore windows to a slim fit. We recommend that you reinstall windows every two months. This is very effective.

 

11. Change the system boot time

 

Although you already know how to add and delete some random boot programs, do you know what the computer is doing during the period from boot to windows? Or, what program is executed? Those programs must be fully loaded before entering windows. Have you ever thought that if you can delete unnecessary programs during startup, will the boot speed be accelerated? The answer is yes! To modify the settings, press start, select execute, and type win. INI. After it is enabled, you can delete the content of the following sections. Delete the content and do not delete the title! They include: [compatibility], [compatibility32], [imecompatibility], [compatibility95], [modulecompatibility], and [embedding].

 

Ii. Hardware

 

1. Disable hard disk DMA mode in Windows

 

Hard Disk DMA mode everyone should know it, the PATA hard disk mode has dma33, dma66, dma100 and dma133, the latest SATA-150 has come out! Generally, most people use the PATA hard disk. The hard disk uses the DMA mode, which is 2 ~ faster than the previous Pio mode ~ 8 times. The use of the DMA mode plays a substantial role in the system performance. But do you know? In Windows 2000, XP, and 2003, the hard disk's DMA mode is sometimes disabled and automatically switched to Pio mode! This results in a sudden decline in hard disk performance in the above system, the most obvious phenomenon is: the system boot speed is obviously slow, generally, when a Windows XP system is started, the slide from left to right can be up to 2 ~ The system can be started four times, but this problem may take 5 ~ 8 times or more! In addition, the hard disk operation is obviously slow when running the system. When running some large software, the CPU usage often reaches 100%, causing a pause. When playing some large 3D games, the screen is obviously paused, when the above problem occurs, you 'd better check whether the DMA mode of your hard disk is disabled by the Windows system. Check whether your system has enabled the DMA mode:

A. Double-click "Management Tools" and 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 "Main ide controller ";

 

E. Click "Advanced Settings ".

 

If "device 0" is displayed, the following transmission mode should be set to "DMA (if available)", and then "current transmission mode". If "Ultra DMA mode * (* is a number, dma33 is 2, dma66 is 4, dma100 is 5, dmaloud is 6) ", then your system is normal, however, if you set "Ultra DMA mode 6, but now it is "Ultra DMA mode 4", "Ultra DMA mode 2", or "Pio mode" and cannot be changed! The system may shut down the DMA mode.

 

2. Check whether the CPU and fan are operating properly and cooling enough

 

When the CPU fan speed slows down, the CPU temperature increases. To protect the CPU security, the CPU automatically reduces the operating frequency, resulting in a slow computer operation. There are two methods to detect the CPU temperature. You can use the finger method to test whether the temperature of the processor is hot, but note that you must unplug the power plug before using this method, then a ground wire is connected to prevent the static electricity on the body from penetrating the CPU and causing damage. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.

 

The appropriate temperature varies depending on the type and model of the processor. But in general, the temperature should be less than 110 degrees. If you find that the processor test is higher than this temperature, check whether the fan in the chassis is working properly.

3. Impact of USB and scanner

 

Because each drive (including the optical drive) is detected during Windows Startup, if the optical drive is placed with a CD, the startup time of the computer will be extended. So if a computer is installed with a scanner or a USB hard disk is connected at startup, try to disconnect them first to see if the startup speed has changed. Generally, due to the slow speed of the USB interface, the corresponding device will have a significant impact on the startup speed of the computer. Try to connect the USB device after startup. If you do not have a USB device, we recommend that you disable the USB feature directly in the BIOS settings.

 

4. Whether disk compression is used

 

Because "disk compression" may cause a sharp decline in computer performance and slow down the system speed. Therefore, you should check whether "disk compression" is used. In this case, right-click "my computer" and select "attribute" from the pop-up menu, to check the properties of the drive.

 

5. Nic impact

 

If you do not set the NIC properly, it will significantly affect the system startup speed. If your computer is connected to the LAN, after installing the NIC driver, by default, the system automatically obtains the IP address through DHCP, but most companies' LAN does not have DHCP servers. Therefore, if you set it to "automatically obtain the IP address ", when the system starts, it will constantly search for DHCP servers in the network until the IP address or timeout is obtained, which naturally affects the start time. Therefore, it is best for LAN users to specify a fixed IP address for their computers.

 

6. folder and printer sharing

 

When Windows XP Professional Edition is installed, the computer may experience slow startup. Sometimes the system seems to be dead. After logging on to the system, the desktop will not appear, the computer is like stopping the reaction and can be used normally in 1 minute. This is because, after the bootvis.exe program is used, the mrxsmb. dll file adds 67 seconds for the computer startup!

 

To solve this problem, just stop the shared folder and printer: Select Start → settings → network and dial-up connections, right-click local connection, and select Properties ", in the displayed window, cancel the check box before Microsoft network file and printer sharing under "Use the following selected components for this connection" and restart your computer.

7. misconfiguration of system accessories

 

Some users tend to ignore some small things when assembling machines, resulting in improper matching of computer accessories and a speed bottleneck. For example, some friends choose a high CPU grade, but they can use sound cards but have bought ordinary cheap goods. In fact, this is often not worth the candle. In this way, the computer needs to adopt software decoding because the sound card occupies a high CPU resources and its data transmission speed is slow when running a game or playing a video disc, it often causes audible pauses, or even program running intermittently. Another example is that some of my friends' machines are upgraded. In the past, some components on old machines, such as memory stick, were reluctant to be discarded and used on new machines. However, due to the speed limitation of old memory, it is often necessary for new machines to lower the speed to accommodate it, thus reducing the performance of the entire machine and greatly affecting the overall operation speed.

 

8. hardware driver

 

Many players are new players who do not know much about hardware drivers and do not know how to install drivers when installing windows. As a result, they can cook dumplings in the teapot without a mouth, the failure to utilize hardware performance greatly wastes resources. We all know that the same hardware with drivers of different versions or drivers of different manufacturers often cause great performance differences, not to mention the absence of drivers. Taking playing a video album as an example, even if you are the most advanced TNT video card, if the driver is not installed, it will not use any acceleration function of the display card when playing a video disc, instead of using software to simulate acceleration, the effect is naturally terrible.

 

9. Disconnect unused network drives

 

To eliminate or reduce the number of network connections that must be reestablished for windows, we recommend that you disconnect unnecessary network drives, that is, access "my computer ", right-click the network drive that has been mapped and select "disconnected.

 

10. Insufficient memory

 

One of the advantages of the Windows operating system is the multilinearity and multitasking. The system can use the CPU to perform time-sharing operations so that you can do many things at the same time. But there are naturally some advantages and disadvantages, and multi-task operations will also put forward higher requirements for your machine. Friends know that even the most commonly used word software requires about 16 MB of memory, and 64 MB of memory is not enough when running large software such as 3D Max. In this case, the system automatically uses the hard disk space to virtualize the primary memory for running programs and storing swap files and various temporary files. Because the hard disk is a mechanical structure, and the memory is an electronic structure, the speed of the two is several orders of magnitude. Therefore, using the hard disk to virtualize the main memory will greatly reduce the running speed.

11. Insufficient hard disk space

 

One of the disadvantages of using the Windows system platform is that you are not clear about file management. Sometimes you do not know whether the file is useful to the system. Therefore, the number of files in the Windows directory is increasing, the capacity is getting bigger and bigger. In addition, the current software prefers to grow bigger, and some temporary files and swap files generated by the system will all make the hard disk available space smaller. When the available space of the hard disk is small to a certain extent, there will be a lack of available space for the system's swap files and temporary files, reducing the operating efficiency of the system. More importantly, because we frequently store and delete various software on the hard disk, the available space on the hard disk becomes fragmented. Therefore, the system often does not store files in a sequential order, this will cause the system to frequently move the head when storing and reading files, greatly reducing the system operation speed.

 

12. Too many hard disk partitions are also incorrect.

 

If your Windows 2000 instance is not upgraded to SP3 or SP4, and too many partitions are defined, the startup may become long or even suspended. Therefore, we recommend that you upgrade the latest SP4, and do not divide the hard disk into too many areas. Windows must load each partition at startup. As the number of partitions increases, the total time required to complete this operation will also increase.
