1 Reprint XP Shutdown and Automatic Restart Solutions.

The computer XP system cannot be shut down normally! Solution of automatic restart after shutdown

This is a malfunction or abnormality of the shutdown function. How to solve this fault?

First, the shutdown process and fault causes

Windows shutdown program will perform the following functions during shutdown: complete all disk writes and clear the disk.

Cache, execute window closing program, close all currently running programs, and convert all drivers in protected mode.

Realistic mode.

The main reasons for the failure of Windows system shutdown are: the sound file was destroyed when choosing to quit Windows; no

Properly configure or damage the hardware; BIOS settings are incompatible; Advanced power management or advanced configuration in BIOS

And power interface "is not set correctly; The video card is not assigned IRQ in real mode; Program or TSR

The program may not have closed correctly; Incompatible, damaged or conflicting device drivers are loaded.

Second, the fault analysis and solutions

1. The sound file was damaged when exiting Windows.

First, you can determine whether the "Exit Windows" sound file is damaged-click Start → Settings →

Control panel, and then double-click sound. In the event box, click Exit Window. In "Name"

Click (None), click OK, and then turn off the computer. If Windows shuts down normally,

If closed, the problem is caused by exiting the sound file. To solve this problem, please choose one of the following actions: From standby state.

Recover the sound file in the copy; Reinstall the program that provides the sound file; Configure Windows not to play Exit.

Windows "sound file.

2. Fast shutdown is abnormal

Fast shutdown is a new function in Windows 98, which can greatly reduce the shutdown time. However, this feature is different from some.

The hardware is incompatible. If these hardware are installed in the computer, it may cause the computer to stop responding. You can disable fast.

To shut down quickly, click Start → Run, type Msconfig in the open box, and then click.

Ok (see figure 1). Click Advanced → Disable Fast Shutdown, click OK, and then click OK again.

Settings. "The system prompts you to restart the computer, you can restart. If the computer can be shut down normally, it can be shut down quickly.

It may not be compatible with one or more hardware devices installed on the computer.

3. Pay attention to "advanced power management"

Advanced power management (APM) functions on the computer may also cause shutdown, crash or black screen problems. But in order to determine APM

Whether it will cause the shutdown problem, you can click Start → Settings → Control Panel, and then double-click the system.

Unification. " On the Device Manager tab, double-click the system device. Double-click the advanced power supply in the device list.

Manage, click the Settings tab, and then click to clear the Enable Power Management check box. Keep clicking

Until you get back to the control panel. Restart the computer. If the computer shuts down normally, please shut down the computer.

Machine, the cause of the problem may be APM.

4. Startup and shutdown faults

When you are using a computer, you will often encounter the message "It is safe to shut down" when Windows starts.

Computer failure ",or immediately shut down when starting or restart when shutting down. Generally speaking, the reason for this failure

This is caused by Wininit.exe or Vmm32.vxd file corruption. The solution is to reinstall the program from Windows.

Retrieve these two files in a sequential compressed package. Enter the Windows\\system subdirectory and rename Vmm32.vxd to

Vmm32。 XXX Make a backup, and then click Start → Programs → Accessories → System Tools → System.

Unified information. "Click Tools in the menu bar, then select System File Checker, and click Install Disk from.

Extract a file "(see Figure 2), and then enter" Wininit.exe "or" "in the" File to be extracted "box.

Vmm32.vxd Click Start, and then follow the onscreen instructions to download from the Windows CD-

The ROM or installation disk unzips the file to the C:\\Windows\\System folder, and then repeats this step to replace the file.

Wininit.exe or Vmm32.vxd

5. The mistake is 5. Bootlog.txt file.

In addition, the location problem in the Bootlog.txt file will also lead to the failure of shutting down the black screen. You can use text editing first.

Devices, such as Notepad, check the entry "Terminate" in the Bootlog.txt file. These entries are located in the file.

Finally, it can provide some clues for the cause of the problem. For each "Terminate=" entry, find a matching.

Entries with "EndTerminate=".

Terminate=Query Drivers indicates that there is a problem with the memory manager;

Terminate=Unload indicates that the network conflicts with the real mode or network driver in Config.sys;

Terminate=Reset display indicates that the video driver may need to be updated;

Terminate=Rit indicates that there is something wrong with the sound card or mouse driver;

Terminate=Win32 indicates that a problem related to a 32-bit program is blocking the thread.

If the last line of the Bootlog.txt file is "EndTerminate=KERNEL", Windows 98 can shut down successfully.

Close.

6.6 There is a problem. Or Autoexec.bat

In addition, can you check whether the Config.sys file conflicts with the Autoexec.bat file? Make sure first.

Whether there is a conflict in the Config.sys file or the Autoexec.bat file, you can click Start and then click Run.

All right. "In the open box, type Msconfig, and then click OK. Click Diagnostics Start,

Then "OK" When prompted to restart the computer, click OK. If the computer is turned on or off

Incorrect shutdown, please determine which line of Config.sys or Autoexec.bat file caused the problem.

To determine the line that is causing the problem, please restart the computer. Please hold down the Ctrl key when the computer restarts. from

Select Safe Mode from the Start menu. Click "Start" after startup, and then click "Cloud".

All right. "In the open box, type Msconfig, and then click OK. Click to clear

There is no check box for the window icon row in the Config.sys and Autoexec.bat tabs. Use this Config.sys text

, click to enable a row. Click "OK". When prompted to restart the computer, click OK.

If the computer is turned on and off normally, please start another line, repeat the above steps and start it step by step.

Use the lines in the Config.sys file and the Autoexec.bat file until you find the problem.

7. Internal system problems

In addition, you can also determine whether there is an internal system problem. Click Start → Run. In the box that opens, type

Enter "Msconfig" and click "OK". On the General tab, click Advanced. Click to clear

The following check boxes in the advanced troubleshooting settings, and then click OK: Disable system ROM breakpoints; forbidden

The virtual hdirqEMM does not contain A000-FFFF. When prompted to restart the computer, click OK. if

The computer started normally. You can repeat the above steps, but in step "Click to clear advanced troubleshooting settings".

When the following check boxes are selected, click to select them. Repeat this process, selecting one other check box at a time until it is sent.

Now the computer can't shut down normally. Once you find that the computer can't be restarted or turned off, you can repeat the above steps again.

Click to clear the check box just selected.

8. Check CMOS settings

Incorrect CMOS settings can also cause computer shutdown problems. When the computer starts, you can press the "Del" key to enter CMOS.

Setup page, focusing on checking CPU external frequency, power management, virus detection, IRQ interrupt opening and closing, disk startup sequence, etc.

Whether the project settings are correct. The specific setting method can refer to your motherboard manual, which has very detailed settings.

Ming. If you really don't know much about its settings, I suggest that you can directly install or remove the CMOS battery and short-circuit it with CMOS.

Line, select the factory default settings.

9. Hardware problems

In addition, some problems in the BIOS itself or the hardware system itself will also cause the failure to shut down. When you find yourself

When new hardware is installed, the system hangs when it is turned off, for example, the monitor is black and the keyboard and mouse are unresponsive.

There may be compatibility issues with drivers configured for new hardware. In order to solve this problem, the hardware of the third party cannot be used at the same time.

To solve the problem, we usually go to the hardware manufacturer's website to find a solution, find the latest driver of the device and download it.

When installed in your machine system, this problem can usually be solved.

Solve the "problem" of not shutting down normally

1Q#Q'o V%eW？ A friend of the guest once asked the author: Why can't my computer shut down automatically? I have to

Solve such problems for them and turn experience into theory by the way. I believe this article can also help you solve some problems.

question

For ATX-driven computers, Windows 98 provides the automatic shutdown function of the computer. But in many cases, our

The computer can't shut down normally and smoothly, and sometimes it will crash or lose its response during the shutdown process, which makes us have to restart.

Restart the computer or power off the computer forcibly. Is there any way to keep the computer from breaking down? Let's have one

Get up and analyze the reasons.

First, there will be music when the phone is turned off.

Many friends like to set a closed music in the sound setting of the "control panel" and add one to the cold computer.

A little angry. If the closed music file is damaged for some reason and cannot be played normally, then the shutdown process is being performed.

Timing will naturally fail. If your computer can't shut down normally, and you just set the shutdown music, you might as well first.

Set the power-off music to "None" (as shown in figure 1) and try again.

Second, the drivers are not compatible.

Incompatibility between hardware drivers will also cause the computer to shut down normally. Here's a trick, every time

After Windows 98 fails to shut down, it will be recorded in the Bootlog.txt file under the root directory of drive C to find its fault.

"Terminate=" and "EndTerminate=" in record the reasons for the failure of closing.

Take the computer I'm using now, for example. I used the video card of the little movie TNT2 M64 to play.

It was normal at first, but later I found that as long as I ran the 3D game, no matter how long I played it, if I quit the game, I would shut it down immediately.

The machine must be out of order. I don't want to restart it after a normal shutdown. So I checked after the shutdown failed.

Bootlog.txt file, at the end of the file, I found these records:

Terminate = Reset display

EndTerminate = resets the display.

EndTerminate = user

From the record, it seems that the shutdown failure has something to do with the graphics card, so I installed a new version of TNT2 on the driver CD.

Driver, the fault still exists. The latest DirectX 8. 1 has been installed, but the problem has not been solved. Finally, in a

Run DirectX diagnostic tool "DxDiag" for the second time (this program is in C: \ \ Program files \ \ DirectX \ \ Setup.

Record), in the "display" page prompt "file Nvdisp.drv no digital signature ..." It seems that I used to.

The installed TNT2 driver failed to pass the Microsoft certification, so I downloaded NVIDIA_WHQL of TNT2 on the Internet.

Microsoft certification) Windows 9X latest driver version 28.32 WHQL, after installation, restart and then run.

"DxDiag" program, prompting "No problem found" on the "Display" page, and running various 3D games at this time.

After all, it can be closed smoothly.

After many tests, it is found that the general shutdown fails. As long as it is not the hardware itself, you can check Bootlog.txt.

File search reason. The records listed below may cause the computer to fail to shut down. You can use your computer.

The situation shown in Bootlog.txt Find out why:

There is a problem with the Terminate=Query driver memory manager.

Terminate=Unload Network Network conflicts with the real-mode network driver in Config.sys

There is something wrong with the terminal = resetdisplay graphics card settings or drivers.

Terminate=RIT sound card or some old mouse drivers have timer-related problems.

Terminate=Win32 Some 32-bit programs have locked threads.

You can find and solve the computer shutdown fault according to the situation of your computer and compare the above reasons.

Third, software is hard to quit.

Sometimes the shutdown fails not because of the computer system itself, but because some programs can't quit normally when it is shut down.

Many friends don't close all running programs or software before shutting down, but let Windows shut down.

Turn them off automatically. Indeed, when the computer executes the shutdown program, most software or programs can automatically shut down, but it also

A few can't quit automatically, so it is necessary for us to check whether there are other software or programs when the computer is turned off.

Running.

I found that the computer often can't shut down normally, and it still doesn't work if the "quick shutdown" is disabled. Later, I found that when the computer was loaded,

Line a software (because this software is resident from memory, it will automatically appear in the system tray after running), if

I didn't eject the computer from the system disk when I turned it off, so it is definitely impossible to turn it off. When it is turned off.

Before shutting down the running software, you can shut it down normally. Therefore, it is best to exit each one when you turn it off.

Execute the program, and then execute the shutdown command.

Fourth, haste makes waste.

There is a Bug in the shutdown program of Windows 98 itself, which is "fast shutdown". In many cases, it makes.

We can't shut down normally, as the saying goes, "haste makes waste."

The solution is simple, that is, "disable fast shutdown". Click Start → Run and enter.

Click "OK" after "msconfig". The System Configuration Utility window appears, click the General page,

Click the "Advanced" option again, and set "Disable Fast Shutdown" in the "Advanced Troubleshooting Settings" window that appears at this time.

Put a tick in front of the machine (as shown in Figure 2), thus completing the whole operation.

I. Software

1. Virus damage

A typical example is the "shock wave" virus that caused serious damage to computers around the world some time ago. It will also

Prompt that the system will start automatically after 60 seconds. In fact, as early as the DOS era, many viruses can automatically restart your calculations.

Machine.

Whether it is virus damage or not, we can use the latest version of anti-virus software for anti-virus, and we can usually find viruses.

Existence. Of course, there is another possibility, that is, someone maliciously hacked into your computer while you were surfing the Internet and released a Trojan horse.

Order. In this way, the other party can remotely control all the activities of your computer, including, of course, restarting your computer.

Move it. For some trojans, it is not easy to remove them, so it is better to reinstall the operating system.

2. The system file is corrupted.

When system files are destroyed, such as KERNEL32.DLL under Win2K and fonts under Win98 FONTS directory.

The basic files at runtime are destroyed, and the system will be forced to restart when it is started. you can

In order to do an experiment, try to rename the font in WIN98 directory to "FONTS". When you open it again, our plan

The computer will start again and again.

For this kind of fault, because it can't enter the normal desktop, it can only be installed or reinstalled with cover.

3. Timing software or task planning software works.

If you set to restart or load some working programs in the "Planning Taskbar", when the time comes.

, the computer will start again. In this case, we can open the "Start" item and check whether there is one.

If you are not familiar with the execution files or other scheduled work procedures, please block them before starting the inspection. Of course, we can also.

Enter the "Msconfig" command directly in "Run" and select the startup item.

Second, hardware.

1. The power supply voltage is unstable.

The working voltage range of switching power supply for general household computers is 170V-240V. When the power supply voltage is lower than 170V, the calculation is carried out.

The machine will automatically restart or shut down. Because we sometimes don't feel the fluctuation of the mains voltage, we will mistake it for calculation.

The machine automatically restarts for no reason. Love music network free music blog1} j+ksu; Male: k%S)Y

Solution: For areas with unstable power supply, you can buy UPS power supply or 130-260 V wide switch.

Power supply to ensure the stable operation of the computer.

2. The plug-in or power socket is of poor quality and poor contact.

Most of the patch panels on the market are of poor quality, and the internal contacts are all welded by hand, and acid welding is often used.

Agent, so it is easy to cause solder joint oxidation in future use, resulting in open circuit or leakage between live wire and zero line. Because of the hand

Work welding, at the same time, due to the poor elasticity of phosphorus brass sheet, it won't be long before it loses its elasticity, leading to the main

The power plug of the machine or monitor has poor contact, resulting in large contact resistance, which will generate a lot of heat when working for a long time.

And lead to virtual connection, which will be manifested as host restart or display black screen flashing.

Another possibility is the wall socket in our home. Most wall sockets are not installed by professionals.

So the wiring inside the socket is very irregular, especially we often use high-power electric heaters.

It is easy to cause internal heating, oxidation and virtual connection to form intermittent power failure, resulting in computer restart or display flashing.

Elephant.

Solution:

(1) Don't buy cheap patch panels to save money, buy some brand-name patch panels, because they are internally

It is automatically installed and crimped by the machine without manual welding.

(2) Whether it belongs to the problem of virtual connection inside the wall socket, you can try replacing the host with a wall socket.

Whether there is the same automatic restart problem.

3. The computer power supply is insufficient or has poor performance.

This situation is also common, especially when we add new equipment to the host, such as replacing high-end monitors.

Card, add a burner, add a hard disk, it is easy to appear. When the host is working at full speed, such as running a large-scale

3D games, high-speed burning or preparing to read CDs, at first, the data was copied by two disks, probably because

Instantaneous power shortage causes power supply protection and stops output, but when the power supply stops output, the load is reduced.

At this point, the power supply starts again. Because the recovery time after protection is very short, the performance given to us is that the host automatically resets.

Kay.

There is another situation, that is, the performance of the host switching power supply is poor, although the voltage is stable and within the normal allowable range, but

Because the harmonic content in its output power supply is too large, it will also cause the host to crash or restart frequently. In this case, I

It is normal for students to measure voltage with a multimeter, so it is better to change to an excellent power supply.

Solution: Now replace the high-quality and high-power computer power supply.

4. The power plug of the host switch power supply is loose, with poor contact and tight plug.

In this case, most of them will appear on DIY machines, and the power cord of the host power supply has not passed 3C certification, which is different from the power supply.

The sockets don't match. When we shake the table or touch the host, the host will automatically restart, usually with a slight.

The electric spark makes a "snapping" sound.

Solution: Replace the high-quality 3C certified power cord.

5. The ATX20 socket of the motherboard power supply is soldered in vain, and the contact is poor.

This kind of fault is not common, but it does exist, mainly because the ATX20 pin plug is moved left and right when the host is working normally, depending on the host.

Whether the machine will automatically restart. It is also important to check whether the reed inside the 20-pin power plug is oxidized.

It is easy to cause large contact resistance and poor contact, leading to the host computer crash or restart. Sometimes it is necessary to check the tail of the 20-pin plug.

Whether the connecting wire is firm.

Solution:

(1) If the solder joints of the main board are in virtual welding, repair the welding directly with an electric soldering iron. Note: in the motherboard, hard disk, graphics card, etc.

When welding the computer board, be sure to ground the soldering iron or unplug the power plug when welding.

(2) If it is a power problem, it is best to replace a good power supply.

6.CPU problem

When some functional circuits in the CPU are damaged and the secondary cache is damaged, the computer can also start and even enter the normal desktop.

Normal operation, but it will restart or crash when performing a special function, such as drawing a watch, playing VCD, playing games, etc.

Wait a minute.

Solution: Try to shield the second-level cache (L2) or the first-level cache (L 1) in CMOS to see if the host can work normally.

Operation; Or just change to a good CPU. If it can run normally after shielding, it can still make do.

Try to use it. It's slower, but it will save money.

7. Memory problems

If a chip on the memory stick is not completely damaged, it is likely to pass the self-test (although most of them are set).

POST), but the runtime will restart unexpectedly because of the function failure caused by the large calorific value of the memory. Most of the time,

When the memory is damaged, it will give an alarm, but there are still faults such as no alarm and no power supply after the memory is damaged. It is best to use the exclusion method.

Method, the fault location can be determined quickly.

8. Optical drive problem

If the CD-ROM drive is damaged internally, it will also lead to slow startup or self-test failure of the host, or it may be during work.

Suddenly restart. In the latter case, if we replace the optical drive, it is probably the power consumption of the optical drive.

Caused by differences. What you need to know is that although the ATPI interface of the optical drive is the same, the pins of different manufacturers are different.

Different definitions. If there is something wrong with our hard disk cable, we may not ask about the use of a certain brand of optical drive.

Problem, but for other brands of optical drives can not work, we need to pay attention.

There is something wrong with the quality of 9.9. Reset key.

If the reset switch is damaged, the internal reed is always in the short circuit position, and the host computer cannot power on for self-test. But when?

When the elasticity of the reset switch is weakened or the keys on the chassis are not easy to bounce when pressed, it will appear during use, because even if

You touch the chassis or it is in normal use, and the host suddenly restarts. Therefore, when the reset switch cannot be pressed freely.

Be sure to check it carefully, and it is best to replace the reset button switch with a new one, or lubricate the external keys of the chassis.

Slip machining.

There is another case, because the insulation layer of the reset switch lead in the chassis has fallen off too much during welding, and it has been used.

Repeated unpacking in the process will cause the reset switch line to be too close, resulting in collision and automatic restart of the host.

10. Automatically restart when connecting the network card or parallel port, serial port and USB interface to external equipment.

This situation is generally caused by peripheral faults, such as damage to the parallel port of the printer, short circuit to ground, and computer automation.

Slow restart, unable to open file (software-caused failure)
