Windows slowdown Cause analysis and solution

Everyone wants the computer to enter the Windows system immediately without waiting, or the system will not be slower and slower when used, but for various reasons, these wishes are often not realized. Even when you turn it on, you can crash or use it more and more slowly. In fact, sometimes the slow startup speed of Windows is not a problem of its own, but caused by some devices or software. This article is the three major aspects of software, hardware and viruses to analyze the slowdown of the system, and provides acceleration techniques for the system.

The first part of the system slows down

First, the software chapter

1, set the virtual memory

There is a very large data exchange file in the hard disk, It is a place reserved for virtual memory by the system. Many applications are often used. Therefore, the system needs to make a large amount of data access to the main memory. Therefore, the speed of accessing this file constitutes a speed affecting the computer. Very important factor! Generally, Windows presets the virtual memory by the system itself. It automatically adjusts the size of the swap file according to the needs of different programs. However, such a large size reduction will bring additional burden to the system and make the system slow down! In view of this, users should customize the minimum and maximum values ​​of virtual memory to avoid frequent size changes. To set the virtual memory, right click on "My Computer" and select "Properties". In the "Properties" dialog box in the "Advanced" option, set "Virtual Memory".

2, completely delete the program

Everyone knows that if you want to delete some programs, you can go to the "Add /Remove Programs" operation, but everyone knows, it will only Can you delete the program, but will not help you delete the registration code of the program and some login items? To completely remove the program, find some "professional" software to delete! The nortonuninstall produced by symantec, because some parts have destroyed the copyright of some deleted software, so the world has stopped selling, because of this, symantec only came out cleansweep, but on the function, nortonuninstall is even better! Closer to home, in fact, in addition to these two software, there are many similar software can effectively delete the program.

3. Check application software or drivers

Some programs slow down the system when the computer system starts up. If it is for this reason, we can start from "safe mode". Because this is the original boot, "safe mode" runs slower than it does during normal operation. However, if you start in "Safe Mode" and find that the computer starts faster than normal startup, then a program may be causing the system to slow down.

4, too many desktop icons will cause trouble

There are too many icons on the desktop will also reduce the system startup speed. Every time Windows starts and displays the desktop, you need to find the icons of the desktop shortcuts one by one and load them. The more icons, the more time it takes. At the same time, some anti-virus software provides the system startup scan function, which will take a lot of time. In fact, if you have already opened the real-time monitoring function of the anti-virus software, then the scanning system will be redundant when booting, or disable this function. ! It is recommended that you put the less commonly used desktop icons in a special folder or simply delete them!

5, ADSL caused system startup slow

By default, Windows XP will perform self-test on network devices such as network cards when booting. If the IP address of the network card is not configured, It will be set, which may be the real cause of slow system startup. At this point we can open the "Local Area Connection" property menu, double-click "Internet Protocol" in the "General" item to open the "TCP /IP Properties" menu. Configure the IP address of the NIC as a value that is not used in the public network (the default gateway is 192.168.1.1), such as 192.168.1.X. X takes a value between 2 and 255. The subnet mask is set to 255.255.255.0, default gateway and DNS default settings.

6, the impact of fonts on speed

Although Microsoft claims that the Windows operating system can install 1000 to 1500 fonts, in fact, when you install more than 500 fonts, there will be problems. For example, fonts disappear from the application's font list and Windows startup speed drops dramatically. It is recommended that you delete the fonts that are not used or are not commonly used. To avoid accidents after deletion, you can make the necessary backups first.

7, delete the random start program

What is the random start program? A random starter is a program that is loaded at boot time. Random start program not only slows down the speed of booting, but also consumes computer resources and memory faster. Generally speaking, if you want to delete the random startup program, you can delete it in the "Startup" list, but if you want to be more detailed, for example, QQ Software such as popkiller cannot be deleted in the "Startup" list. Go to "Attachment Application", then go to "System Tools", then go to "System Information". After entering, press "Tools" in the upper toolbar. ", then press "System Configuration Editing Program", after entering, in the "Startup" dialog box, it will list the random startup program loaded when starting the computer! XP system You can also terminate the system random start program by calling "System Configuration Utility" in the input "Msconfig". The 2000 system needs to copy the msconfig program from XP.

8, cancel the background and close activedesktop

I do not know if you have noticed, we have been placed on the beautiful background of the desktop, in fact, is a waste of computer resources! Not only that, but it also slows down the speed at which the computer is executing the application! I want to beautify the desktop, but slow down the speed of the computer, so we need to not use the background, by right-clicking on the desktop, then press the content, then in the "background" dialog box, select "none" In the "look and feel" dialog box, the preset blue on the desktop is changed to black... As for closing activedesktop, it means that you can close the web screen from the desktop, for example, right click on the desktop. , then press the content, then in the "background" dialog, there is a background called Windows XX, that is the web screen! So don't open the system if it is not high.

9, Kingsoft Internet Security upgrade can also cause the system to slow down

If you upgrade the Kingsoft Internet Security and found that the system speed is slow, PU occupancy rate has been high, then this problem may be the drug tyrant upgrade File trouble, if a friend is also in the situation after the upgrade, please proceed as follows: first enter the installation directory of the drug tyrant, find the KAExtend.DAT file, then delete it, then click on the drug tyrant "Tools /Online Upgrade", This file can be resolved by updating the KAExtend.DAT file online and finally restarting the computer.

10, make Windows more slim

Compared with DOS
system, Windows is too large, and with your daily operation, install new software, load and run Libraries, adding new games, etc. make it even bigger, and more importantly, it's not just its directory, but its registry and runtime. Because even if a program is deleted, the DLL file it uses will still exist, so with the use of Windows, the DLL dynamic link library file that needs to be loaded when Windows starts and exits is getting bigger and bigger, and the natural system runs faster. It is getting slower and slower. At this point we need to use some programs to completely remove the DLL, they can make Windows restore a slim figure. It is recommended that the best players should reinstall Windows every two months, which is very effective.

11, change the system boot time

Although you already know how to add and delete some random startup programs, but you do not know, during the boot to the time to enter Windows What is the computer doing? Or is it, what program is being executed? Those programs must be fully loaded before they start to enter Windows. Have you ever thought about it, if you can delete some unnecessary startup programs, will the speed at boot be faster? The answer is yes! If you want to modify it, you can press "Start", select "Execute", and then type win.ini. After opening, you can delete the contents of the following paragraphs. Delete the content, don't even delete the title! They include: [compatibility], [compatibility32], [imecompatibility], [compatibility95], [modulecompatibility], and [embedding].

Second, hardware articles

1, Windows system to shut down the hard disk DMA mode

DMA mode of the hard disk should everyone Know, the hard disk PATA mode has DMA33, DMA66, DMA100 and DMA133, the latest SATA-150 are out! In general, most people still use the PATA mode hard disk. The DMA mode of the hard disk is 2~8 times faster than the previous PIO mode. The use of DMA mode has played a substantial role in the performance of the system. But do you know? Windows 2000, XP, and 2003 systems sometimes turn off the DMA mode of the hard disk and automatically switch to PIO mode! This causes a sudden drop in the performance of the hard disk in the above system. The most obvious phenomenon is that the system startup speed is obviously slower. Generally speaking, the normal left-to-right slider of the Windows XP system starts up to 2~4. The secondary system can be started, but this problem may go 5-8 times or more! Moreover, when running the system, the hard disk operation obviously feels slow. When running some large software, the CPU usage often reaches 100% and pauses. When playing some large 3D games, the screen has obvious pause. When the above problems occur, everyone is the most. Take a look at the DMA mode of your hard drive is not closed by the Windows system itself. Check if your system has DMA mode turned on:

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

b. Click System Tools, and then click Devices. Manager";

c. Expand the "IDE ATA/ATAPI Controller" node;

d. Double-click your "Primary IDE Controller";

e. "advanced settings".

When you see "Device 0", the following transfer mode should be set to "DMA (if available)", then "current transfer mode", if "Ultra DMA Mode * (* is a number, DMA33 is 2, DMA66 is 4, DMA100 is 5, DMA133 is 6)", then your system is normal, but if you set your own "Ultra DMA Mode 6" and have not changed, it is now "Ultra DMA Mode 4" or "Ultra DMA Mode 2" is even more "PIO mode" and can't be changed! It may be that the system has turned off the DMA mode by itself.

2. Is the CPU and fan running normally and cool enough?

When the CPU fan speed is slow, the CPU itself will rise in temperature. To protect the CPU, the CPU will automatically Reduce the operating frequency, which causes the computer to run slower. There are two ways to detect the temperature of the CPU. You can use the "finger method" to test whether the temperature of the processor is hot with your fingers, but it should be noted that in this method, the power plug must be unplugged first, and then a ground wire is connected to prevent the static electricity on the body from penetrating the CPU. Even damaged. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.

Because of the different types and models of processors, the reasonable temperature varies. But in general, the temperature should be below 110 degrees. If you find that the processor's test is above this temperature, check that the fan inside the chassis is working properly.

3, USB and scanner impact
