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.
Part 1 system slowdown
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
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 to the USB after startup.
