The computer becomes very slow, and I want to reinstall the system, but I don't know anything about computers. Please explain the process in detail. I am XP, what is the reason for the slow computer?

Detailed process of installing WINDOWS XP [2005]

1. Press the del key or f2 key to enter the bios settings (buttons on different motherboards are different, usually DEL or F2, please refer to the instructions on the motherboard), and adjust the startup mode of the computer to boot from CD. That is, starting with cdrom,

According to different motherboards, bios settings are different (generally: 1stboot: cdrom).

2. Start the machine, insert the installation CD of xp, and wait for the CD to start.

When "Press any key to boot from CD …" appears, press any key to boot.

3. At this time, the xp installer will run automatically, wait until the interface appears, press enter, then agree to the agreement and press f8.

Next, set aside the space occupied by xp on the hard disk, and recommend more than 5gb. Press "c" to create a partition, enter the size to divide it, press Enter to confirm, then return to the previous menu, and press Enter to install xp on the selected partition.

Then format the hard disk partition and recommend ntfs partition. Of course, if you don't have very high requirements for the safety factor of the system, you can also choose the fat file format for future convenience, which is also possible. Quick format, of course.

4.xp setup begins to format the hard disk.

Xp will then copy and install the files it needs. At this time, you can have a cup of tea and wait. Until an interface appears and the copy is completed, you can wait for the restart. You can press Enter to skip the waiting time of 15 seconds.

After the restart, we will enter the second round of installation. At this time, we don't need to do anything, just wait.

When you install the hardware, you will enter our manual information collection, select the region and text support. One thing to note here is that windows is a multilingual operating system. In the language option, you should choose additional language support, otherwise playing games in traditional Chinese will be garbled.

5. Enter the serial number

Customize the computer name and system administrator password. If you just use the computer yourself, you don't need to set a password. This makes it easy for windows to log in automatically.

Network settings, if you use adsl to surf the Internet at home, you don't need to fill in the ip address, which is a typical setting.

If you surf the Internet through LAN, you need to customize ip and dns and install spx/ipx protocol.

XP system installation novice introduction

Step 1, set the lights:

The so-called optical startup means that the computer reads the optical drive first when it is started, so that if there is a CD with optical startup function in the optical drive, it can be read before the hard disk is started (for example, when installing the system from the CD).

Setting method:

1. Start the computer and hold down the DEL key until the BIOS setup window (usually with blue background and yellow English words) appears.

2. Select and enter the second item, "BIOS Settings". Find the entry or group containing the BOOT text, and find three entries "first", "secend" and "third" arranged in sequence, representing the first boot, the second boot and the third boot respectively. Here we can set it to CD-ROM drive, floppy drive and hard disk in turn. (If you can't see these three E's on this page, the option menu on the right side of the boot is usually "Settings", and you can see them by pressing Enter. )

3. After selecting three startup modes, press F 10 to open the E-text dialog box, press Y and press Enter to restart the computer automatically, which proves that the changed settings have taken effect.

Step 2, install XP system from CD.

Insert the XP installation CD before restarting, and press Enter after seeing the CD ... on the screen. (Note: There are * * * five ". Behind the CD-ROM, so you must press Enter before the fifth point appears to realize the light boot, otherwise the computer will start reading the hard disk, that is, skip the light boot and start from the hard disk. )

After the XP system disk is opened, an installation interface with a blue background will appear. At this point, the system will automatically analyze the computer information without any operation until the display screen turns black, and then a Chinese interface with a blue background will appear.

At this time, the first protocol of XP system appeared. Press F8 (indicating agreement with this agreement), and you can see the information list of all partitions of the hard disk with Chinese operation instructions. Select drive C and press D to delete the partition (remember to back up the useful files of drive C first). The location of drive C becomes "unpartitioned", and then press the c key to create a partition in the original location of drive C (that is, the "unpartitioned" location). There is no need to resize the partition. After that, the position of the original C disk becomes "new unused" and press enter to continue.

Next, there may be a page with the option of formatting partitions. It is recommended to select "Format partitions with FAT32 (fast)". Press enter to continue.

The system began to format drive C, which was very fast. After formatting, the hard disk and the previous WINDOWS operating system are analyzed, which is also very fast, followed by copying files, which takes about 8 to 13 minutes (depending on the machine configuration).

After copying the file (100%), the system will automatically restart. When you see the CD-ROM again, you don't need to press any key to boot the system from the hard disk, because some installation files have been copied to the hard disk (note: you can't take out the CD at this time).

A color XP installation interface with a blue background appears, and the installation progress bar and remaining time are displayed on the left. The initial value is 39 minutes, which is also determined according to the configuration of the machine. Usually, the installation time of P4 and 2.4 machines is about 15 to 20 minutes.

At this point, until the installation is finished, the computer will automatically restart, and there is no need to do anything except enter the serial number and computer information (fill in at will) and press Enter for 2 or 3 times. The system will automatically complete the installation.

The third step is to install the driver.

1. After restarting, take out the CD, let the computer boot from the hard disk and enter the XP setting window.

2. Click Next, Skip, and select No Registration and Finish.

3. Enter the XP system desktop.

4. Right-click the desktop, select Properties, select the Display tab, click the "Customize Desktop" item, select "My Computer", and then select "OK" to exit.

5. Return to the desktop, right-click my computer, select Properties, select the Hardware tab, and then select Device Manager. All computer hardware has a management window, and all options with yellow question marks and exclamation marks in front represent hardware without drivers installed. Double-click to open its properties, select Reinstall the driver, put the corresponding driver CD, and select Automatic Installation. (Audio is a sound card, VGA is a graphics card, and SM is the motherboard. You need to install the motherboard driver first. If there is no SM item, installation is not required. ). After installing all drivers, restart the computer. At this point, the driver installation is complete.

The reason of slow system

I. Software products

1, set virtual memory.

There is a very large data exchange file in the hard disk, which is reserved by the system for temporary storage in virtual memory. Many applications are often used, so the system needs to access a large amount of data to main memory frequently, so the speed of accessing this file constitutes a very important factor affecting the speed of the computer! Generally, the default of Windows is that the virtual memory is managed by the system itself, and the size of the swap file will be automatically adjusted according to the needs of different programs, but such enlargement and reduction will bring extra burden to the system and slow down the operation of the system! In view of this, it is best for users to customize the minimum and maximum values of virtual memory to avoid frequent size changes. To set up virtual memory, right-click My Computer and select Properties. In the advanced options of the Efficiency dialog box, set the virtual memory.

3. Check the application software or drivers.

Some programs will slow down the computer system when they are started. If this is the reason, you can start with "safe mode". Because this is the initial startup, Safe Mode is slower than normal operation. However, if you start in "safe mode", you find that the computer starts faster than normal, which may be the reason why a program causes the system to start slowly.

4. Too many desktop icons will bring trouble.

Too many desktop icons will also slow down the system startup. Every time Windows starts and displays the desktop, it needs to find the icons of 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 system startup scanning function, which will consume a lot of time. In fact, if you have turned on the real-time monitoring function of antivirus software, the scanning system will be a bit redundant when starting, so it is better to disable this function! I suggest that you put the uncommon desktop icons in a special folder or simply delete them!

5. Due to ADSL, the system starts slowly.

By default, Windows XP will self-check network devices such as network cards at startup. If the IP address of the network card is found to be incorrectly configured, it will be set, which may be the real reason for the slow system startup. At this time, 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 card to a value that has not been used by the public network (the default gateway is 192. 168. 1), such as192.1. X, where x is a value between 2 and 255.

6. The influence of font on speed

Although Microsoft claims that Windows operating system can install 1000 ~ 1500 fonts, in fact, when you install more than 500 fonts, there will be problems, such as: fonts disappear from the font list of application programs, and the startup speed of Windows drops sharply. It is suggested to delete unused or commonly used fonts. In order to avoid accidents after deletion, you can make necessary backups first.

7. Delete the random startup program

What is a random boot program? A random boot program is a program that is loaded at boot time. Random startup program will not only slow down the startup speed, but also consume computer resources and memory faster. Generally speaking, if you want to delete random startup programs, you can delete them in the startup list, but if you want to be more detailed, such as QQ, popkiller and other software, you can't delete them in the startup list. You should go to accessory applications, system tools, and then. Press Tools in the toolbar above, and then press System Configuration Editor. After entering, in the "startup" dialog box, the random startup program loaded when starting the computer will be listed in detail! XP system, or you can enter Msconfig in "Run" and call "System Configuration Utility" to terminate the system random startup program. 2000 system needs to copy msconfig program from XP.

8. Cancel the background and close activedesktop.

I don't know if you have noticed that the beautiful background we have been putting on the desktop is actually a waste of computer resources! Not only that, it will also slow down the computer when executing applications! I wanted to beautify the desktop, but it slowed down the computer, so we didn't need the background. To do this, right-click the desktop, click Content, and then select None in the Background dialog box. In the Appearance dialog box, the preset turquoise on the desktop turns black ... As for closing activedesktop, you will be told to close the web screen from the desktop. So don't turn it on if the system configuration is not high.

10, making Windows slimmer.

Compared with DOS system, Windows is too big, and with your daily operation, install new software, load runtime, add new games and so on. It becomes bigger, and more importantly, it is not only its directory, but also its registry and runtime. Because even if a program is deleted, the DLL file it uses will still exist. Therefore, with the long-term use, the DLL files that need to be loaded when Windows starts and exits are getting bigger and bigger, and the running speed of the natural system is getting slower and slower. At this time, you need to use some programs that completely delete dll, which can make Windows slim again. It is recommended that the best players reinstall Windows once every two months, which is very effective.

1 1, change the system startup time.

Although you already know how to add and delete some random startup programs, do you know what the computer is doing from booting to entering Windows? Or, what program is being executed? These programs must be fully loaded before entering Windows. Have you ever thought that if you can delete some unnecessary startup programs, the startup speed will be accelerated? The answer is yes! If you want to modify, you can press "Start", select "Execute", and then enter win.ini. After opening, you can delete the contents of the following paragraphs, even the title! They include: [Compatibility], [Compatibility 32], [ime Compatibility], [Compatibility 95], [Module Compatibility] and [Embedding].

Second, hardware.

1, the Windows system automatically turns off the hard disk DMA mode.

Everyone should know the DMA mode of hard disk. PATA modes of hard disk are DMA33, DMA66, DMA 100, DMA 133, and the latest SATA- 150 has come out! Generally speaking, most people still use the hard disk in PATA mode, and the transmission speed of the hard disk in DMA mode is 2~8 times faster than that in PIO mode. DMA mode plays an important role in system performance. But you know what? Windows 2000, XP and 2003 systems sometimes turn off the DMA mode of the hard disk and automatically switch to PIO mode! This leads to the sudden decline of hard disk performance when using the above system, and the most obvious phenomenon is that the startup speed of the system is obviously slow. Generally speaking, when a normal Windows XP system starts, the slider moving from left to right can start the system up to 2 ~ 4 times, but when this problem occurs, it may go 5 ~ 8 times or even more! Moreover, the hard disk operation is obviously slow when the system is running. When running some large-scale software, the CPU utilization often reaches 100%, which leads to a pause, while when playing some large-scale 3D games, the picture obviously stops. When the above problems occur, you'd better see if the DMA mode of your hard disk is automatically turned off by the Windows system. Check whether your system is turned on in DMA mode:

A. Double-click management tools, and then double-click computer management;

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

C. expand the node "IDE ATA/ATAPI controller";

D. double-click your "main IDE controller";

2. Whether the 2.CPU and fan work normally and whether there is enough refrigeration.

When the speed of the CPU fan slows down, the temperature of the CPU itself will rise. In order to protect the security of CPU, CPU will automatically reduce the running frequency, which will slow down the running speed of the computer. There are two ways to detect the temperature of the CPU. You can use the "finger test" method to test whether the temperature of the processor is hot, but it should be noted that this method must first unplug the power plug and then connect a ground wire to prevent static electricity from penetrating the CPU or even damaging the CPU. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor.

Because the types and models of processors are different, the reasonable temperature is also different. But generally speaking, the temperature should be lower than 1 10 degrees. If the processor test is found to be higher than this temperature, check whether the fan in the chassis works normally.

3, the impact of USB and scanner

Since Windows tests every drive (including the optical drive) at startup, if a CD is placed in the optical drive, it will also extend the startup time of the computer. So if the computer is equipped with scanners and other devices, or the USB hard disk is connected when it is started, then try to disconnect them first to see if the startup speed has changed. Generally speaking, due to the slow speed of USB interface, the corresponding devices will obviously affect the startup speed of the computer, so you should try to connect USB devices after startup. If there is no USB device, it is recommended to turn off the USB function directly in BIOS settings.

4. Do you use disk compression?

Because "disk compression" may cause a sharp decline in computer performance, resulting in a slower system speed. So at this time, you should check whether "disk compression" is used. The specific operation is to click the right mouse button on "My Computer" and select the "Properties" option from the pop-up menu to view the properties of the drive.

5, the influence of the network card

As long as it is not set properly, the network card will obviously affect the startup speed of the system. If your computer is connected to the local area network, after installing the network card driver, the system will automatically get the IP address through DHCP by default, but most companies' local area networks do not have DHCP servers. Therefore, if the user is set to "automatically obtain the IP address", the system will constantly search for DHCP servers in the network at startup until it obtains the IP address or times out, which will naturally affect the startup time. Therefore, LAN users had better specify a fixed IP address for their computers.

6. Folders and printers * * *

Computers with Windows XP Professional Edition installed will also start very slowly. Sometimes, the system seems to give people the feeling of collapse. After logging into the system, the desktop does not appear, and the computer seems to stop responding. It takes 1 minute to work normally.
