Automatic shutdown is a complex process that is accomplished by the system processes Csrss and Winlogon working together and calling the shutdown function Shutdown Systen, which further calls SetSystenPowerState to shut down the driver and other currently executing program subsystems (e.g., Plug and Play Manager, Power Manager, IO Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, and Power Manager). Manager, Power Manager, IO Manager, Configuration Manager, Memory Manager, etc.). In addition, when performing an automatic shutdown, the system has to check the status of various external devices in the current system as well as the status of applications that have not yet been shut down, and process the data in various data buffers. If an error occurs in the above tasks, the shutdown cannot be performed properly. Therefore, in general, before shutting down the system, you should stop all peripherals and close all applications before shutting down the system.
In Windows, it is true that automatic shutdowns often fail, so here are some specific reasons why and how to deal with them.
1. There is a defective auto-shutdown program in the system files. In order to confirm whether it is due to this reason, you can make the following experiments. In the "Start / Run" in the input command "rundll32 user.exe, exitwindows" to see if the normal shutdown. If you can shut down normally under this command, it means that the automatic shutdown program may have some kind of defects, if you are using Win98 system, please in the "Start / Programs / Accessories / System Tools / System Information / Tools / System File Checker" to check the integrity of the system files and patch files. If you use other systems (Me/2000/XP), you can also complete the file repair in the corresponding project. If the patch file still cannot solve the problem, you can only reinstall the system. If you run "rundll32 user.exe,exitwindows" and you can't shut down your computer normally, you may have a defective operating system in some of the system programs, but the way to deal with it is still to patch the system or reinstall the system.
2. The virus and some defective applications or system tasks may cause the shutdown to fail. The first step is to check for viruses and close all applications before shutting down the system. Since some applications are loaded at system startup, you can enter the command "msconfig" in the "Startup" menu (in "Start/Run") to remove the loaded programs one by one. You can subtract the loaded programs from the "Startup" menu (enter the command "msconfig" in "Start/Run") to see if there are any files that affect the shutdown (which will only take effect after a reboot, of course).
3. Peripherals and drivers are not compatible and do not respond to fast shutdowns. In the "Start / Run" in the input command: "msconfig", in the "General" tab, select "Advanced", in the window that opens. ", in the window that opens, select "disable fast shutdown". If you suspect that a peripheral is faulty, you can also uninstall the peripheral to check it one by one, in order to find the affected peripheral.
4. If you have set up a sound file to be used when shutting down Windows, it can also cause the shutdown to fail if the file is corrupted. Please select "Exit Windows" in "Control Panel/Sound/Events" and set the sound name to "None". If you are able to shut down the computer normally after this process, it means that it is indeed due to this reason, and you can reinstall the sound file for use.
5. When Win98 is shut down automatically, it will display "It is now safe to shut down the computer", which is accomplished by the "logos.sys" file in the Windows directory, and if this file is corrupted, it will be displayed as a text message. If this file is corrupted, it will not appear in the above prompts, but in the form of text prompts: "you can now safely turn off your computer", which may also cause the automatic shutdown failure, restore the file can be.
6. After installing WinXP, you can't turn off your computer automatically. If you exclude the various reasons mentioned above, it is possible that the power options in the control panel are incorrectly set, so please check your settings and make sure that the ACPI and APM are working properly. There are also some motherboards that are not fully compatible between APM (Advanced Power Management) in the system BIOS and Win XP (mostly AMI BIOS) and therefore cannot shut down the system automatically. Choosing to shut down becomes restarting the system, in which case you can only shut down manually (press the power switch and hold it for 4 seconds and then release it, if it is less than 4 seconds, it is invalid). The fundamental solution to the problem is to upgrade the motherboard's system BIOS with a new version.
And ~
Windows can not shut down
There are many reasons for this failure, the solution:
1) the cause of computer hardware.
The motherboard BIOS can not support ACPI well, it is recommended to upgrade the motherboard's BIOS, usually can be solved.
The poor quality of the computer's power supply has led to a failure to shut down properly. It is recommended to change a good quality power supply.
2) The cause of the computer software.
Check the Bootlog.txt file. The records listed below may cause the computer to fail to shut down, you can find out the reason according to the situation shown in Bootlog.txt in the root directory of the boot disk in your own computer:
Terminate=Query Drivers Driver Problems
Terminate=Unload Network Can't Load Network Driver Conflict
Terminate=Reset Display Problems with graphics card settings or graphics card drivers
Terminate=RIT Problems with sound cards or some older mouse drivers and timers
Terminate=WIN32 Some 32-bit applications lock up the System Threads
3) Check Advanced Power Management (APM): Open Start|Settings|Control Panel|System and tap Device Manager. Expand System Devices|Advanced Power Management, click the Settings option, and remove the check mark in front of Force APM method. If you can shut down your computer normally after restarting it, the cause of the problem may lie in APM, and you should turn off the Advanced Power Management feature.
4) Disable fast shutdown: Click Start | Run menu, in the command box, type "msconfig" and click OK, then the System Configuration Utility window will appear. Click on the General page, and then click on the Advanced Options, at this time the appearance of the Advanced Troubleshooting Settings window, will disable the fast shutdown in front of the selection box can be checked. If the computer shuts down normally, it means that there is a problem with the fast shutdown item.
5) Check to see if you've closed all your applications when you shut down your computer. If not, you can close all the applications. Because some applications may not be closed properly, and the system can't end the application properly, which leads to a malfunction.
6) Be careful when you use IE 5 or higher to surf the web, they still take up a lot of system resources after exiting, usually leaving the system with less than 80% of its available resources, and running other software after this is prone to errors, which may cause the system to fail to shut down softly.
7) Some software may end up causing the system to fail to shut down properly because some of the operations it performs affect system data or files. This situation is distinguished from poor design of the software, which can be a result of the system's own unfavorable protection of itself, and is sometimes related to multitasking. Although Windows XP has the feature of multitasking, some big software can easily cause malfunction when multitasking is executed at the same time, such as illegal operation, blue screen malfunction and crash. The problem of not being able to shut down caused by this situation usually does not appear the next time you turn on the computer.
8) Some program bugs or some 16-bit software may also corrupt system data or files in memory. Memory-resident software is also prone to cause conflicts that can lead to abnormal system shutdowns. Find out with such problems with the software is not very easy, select "Start" * "Programs" * "Accessories" * "System Tools" * "System Information", open the "Microsoft System Information" dialog box, select the "Tools" * "System Configuration Utility", you can set up to allow or prohibit the "startup" of a number of programs that reside in Windows XP. Other problematic applications will have to find their drawbacks over time so that errors can be avoided in time.
Maybe the power supply is burnt somewhere
You check if there is something burnt
Is it the generator? Never tried it. Not enough voltage or insufficient voltage
Is it not enough voltage?
Or it could be that you have a problem with that computer, maybe it's the power supply of that computer~~~You go into the BIOS and see what the CPU temperature is?
One computer has low power, one has high power.
Responders: A question to scare - Lifter Level 5 5-20 18:35
It must be a power supply problem, the power supply of the assembled computer is not of high quality, there is no way to steadily convert in the case of insufficient voltage, try a different power supply, it should solve the problem.
Respondent: pleinlee - Assistant II 5-20 18:37
First check the contact between the power cord of the host and the host. Next open the case and check the contact.
If the above two are not a problem, then consider whether the main wrench power supply module has a problem or the motherboard capacitors have burst ~
Of course, more likely to be damaged power aging, you can use the replacement method, with a good power supply to replace the original power on try.
Then there may be static electricity problems, see what equipment may be charged to contact the host.
Responders: lfx109816 - Magic Apprentice Level 1 5-20 18:44
It is very likely that the static problem check it and then the phase of the machine to clean up a bit to see how the fan
Responders: still so good - Assistant Level 2 5-20 18:46
You appeared in the cause of this failure is the host of the power supply problem. You can change a power supply to try. After confirming that you can change a power supply, you can also find professional maintenance personnel to repair the power supply.
Answer: zgzzd - Apprentice Wizard III 5-20 18:47
Maybe there is a problem with the generator output power supply, resulting in the host power supply is bad. Ask that friend of yours to borrow a host power supply to try. It should be a problem with the power supply
/question/7519085.html
It's simple, why don't you want it to be infected with a Trojan horse or some other virus
It should be that your generator is aging and the power is decreasing
If a one-minute countdown to shutdown window pops up, it's infected with a virus. A system patch will fix the problem.
Within the warranty period, you can go directly to the merchant.
If it's not infected with a virus and you want to test it yourself, you can test it by reinstalling the system first. Distinguish between software and hardware failures.
If the fault remains after reinstalling the system, you can run and do the test with a minimized configuration. You can also use the replacement method to do the test.
Running into this kind of problem
1, check whether there is a virus
2, CPU problem is too high?
3, system reinstallation (it is best to change the system, so that the old system disk is not good), or re-partitioning first, and then install the system (it is recommended to use DM, PQ partition)
Still does not work, then test the same thing with the minimum configuration!
You should first determine whether there is no problem with your computer software, or whether the virus, with antivirus software to kill a kill, if there is no virus to consider whether the hardware and software problems, you provide too few conditions, but we can recommend that you, check whether the CPU has a problem, such as a bad CPU fan, resulting in the CPU temperature is too high and the machine is dead, and the rest of the method of elimination to check the hardware of the problem. The rest will be checked by the method of elimination to see if it is a hardware problem. There are a lot of reasons why computers shut down automatically, so if you're too busy, go to a computer company and let someone else do the repairs for you.
1 is basically a system problem, reinstallation of the system can solve the problem,
2 if not, and then rule out the problem of excessive power supply load, power supply load will also be shut down, the CD-ROM drive unplugged, and then run the computer to see if it will be shut down,
3 in addition to the problem of network viruses, characterized by unplugging the cable can be troubleshooting
4 memory problems, the computer will not be able to use the computer to run, but will not be able to use the computer to run, so the computer will not be able to use the computer to run. Try a different slot.
1. Virus damage
Since the computer soon after, computer viruses also came into being. When the network has become the information artery of today's society, the spread of viruses is more convenient, so from time to time to interfere with and destroy our normal work. Typical is a period of time ago on the global computer caused serious damage to the "Shockwave" virus, the onset of the system will also be prompted to automatically start in 60 seconds. In fact, as early as the DOS era, there are many viruses that can automatically reboot your computer.
Whether it's a virus or not, we can use the latest version of antivirus software to kill the virus, and it's usually found to be present. Of course, there is also a possibility that when you surf the Internet someone has maliciously invaded your computer and placed a Trojan horse program. This allows the other party to control all the activities of your computer from a remote location, and of course, allows your computer to reboot. For some Trojans, it is not easy to remove them and it is best to reinstall the operating system.
2. System file corruption
When system files are corrupted, such as KERNEL32.DLL under Win2K, fonts under the Win98 FONTS directory, and other essential system files are corrupted, the system will be unable to complete the initialization and forced to reboot at startup. You can do an experiment by renaming the font "FONTS" in the Win98 directory. When you turn on your computer again, our computer will keep rebooting over and over again.
For this kind of failure, because you can not access the normal desktop, you can only override the installation or reinstallation.
3. Timing software or scheduled task software plays a role
If you set up a restart or load certain work programs in the "Scheduled Tasks Bar", the computer will also start up again when the time comes. In this case, we can open the "Startup" item, check if there are any unfamiliar executable files or other timed programs, and block them before booting the computer. Of course, we can also be in the "Run" inside the direct input "Msconfig" command to select the start
Second, hardware
1. utility voltage instability
General home computer switching power supply
General home computer switching power supply range of 170 Volt. Operating voltage range of 170V-240V, when the utility voltage is lower than 170V, the computer will automatically restart or shut down. Because of the fluctuations in utility voltage, we sometimes don't feel it, so we mistake the computer for an inexplicable automatic reboot.
Solution: For areas with recurring unstable power supply, we can purchase UPS power supply or 130-260V wide switching power supply to ensure that the computer works stably.
2. Poor quality of the plug or power outlet, poor contact
Most of the power plug on the market is not good quality, the internal contacts are hand-welded, and often use acidic flux, which is likely to lead to oxidation of the solder joints in the future use of the cause of the circuit breakers or leakage between the fire wire and the zero line. Because of manual welding, and because of the use of phosphorus brass piece of poor elasticity, not long to lose elasticity, resulting in poor contact with the host or the monitor power plug to produce a large contact resistance, in a long period of time will be a large number of heat and lead to a false connection, which will be manifested in the host restart or display black screen flicker.
There is also a possibility that we use the wall socket at home, most wall socket installation is not the use of professionals, so the wiring inside the socket is very non-standard, especially these sockets if we often use high-power electric heaters will easily lead to internal heating oxidation of the false connection and the formation of intermittent power outages, resulting in the computer reboot or monitor blinking phenomenon.
Solution:
① Do not try to save money and buy cheap power plugs, buy some brand-name power plugs, because its internal are automatically installed on the machine crimping, no manual welding.
② For the problem of whether the wall socket internal false connection, we can change the host to a wall socket to try to see if there is the same automatic restart problem.
3. Insufficient power or poor performance of the computer's power supply
This situation is also relatively common, especially when we add new equipment to their hosts, such as replacing high-grade graphics cards, adding a burner, adding a hard disk, it is easy to appear. When the host is working at full speed, such as running large-scale 3D games, high-speed burning or ready to read CD-ROMs, just start, dual hard disk copy data, it may be due to the instantaneous power supply power is insufficient to cause the power supply protection and stop the output, but due to the fact that when the power supply stops the output, the load is reduced, which is when the power supply is started again. Because the recovery time after the protection is very short, so the performance to us is the host automatically reboot.
There is another situation, is the host switching power supply performance is poor, although the voltage is stable is also within the normal allowable range, but because of its harmonic content in the output power supply is too large, will also lead to frequent host crash or restart. For this case we use a multimeter to test its voltage is normal, it is best to replace a good power supply to replace the exclusion.
Solution: Now replace the high-quality high-power computer power supply.
4. host switching power supply mains plug loose, poor contact, not plugged tight
This situation, most of them will appear in the DIY machine, the host power supply with the power cord did not go through the 3C certification, and the power socket does not match. When we shake the table or touch the host will appear host automatically reboot, usually accompanied by a slight electric fire "pop" sound.
Solution: Replace the high-quality 3C certified power cord.
5. motherboard power ATX20 socket has a virtual weld, poor contact
This failure is not common, but does exist, mainly in the host of normal operation, left and right to move the ATX20 pin plug, to see whether the host will automatically restart. Also check the reeds inside the 20-pin power plug for oxidation, which can also easily lead to high contact resistance and poor contact, causing the host to crash or reboot. Sometimes it is also necessary to check the connecting wires at the end of the 20-pin plug, whether they are all secure.
Solution:
① If the motherboard solder joints are soldered, directly with a soldering iron to make up the soldering can be. Note: In the motherboard, hard disk, graphics card and other computer board welding, be sure to soldering iron well grounded, or unplugged from the power supply when welding.
② If it is a power supply problem, it is better to replace a good power supply.
6. CPU problems
Part of the internal function of the CPU circuit is damaged, the second level of cache damage, the computer can start, and even enter the normal desktop for normal operation, but when a special function will restart or crash, such as drawing table, play VCD, play games, and so on.
Solution: Try to shield the second level cache (L2) or first level cache (L1) in CMOS, to see if the host can run normally; or not directly with a good CPU to replace the exclusion. If you can run normally after shielding, you can still make do, although the speed is slower, but after all, save money.
7. Memory problems
Memory stick if a chip is not completely damaged, it is likely to pass the self-test (after all, most of them are set up POST), but in the operation of the memory will be due to the heat of the memory and lead to the failure of the function of the accidental reboot. Most of the time the boot will alarm when the memory is corrupted, but there are still failures where the memory is corrupted without alarming or powering up. It is best to use the method of elimination to be able to quickly determine the site of failure.
8. Optical drive problems
If the optical drive internal damage, it will also lead to slow startup of the host or can not pass the self-test, but also may be in the process of work suddenly reboot. For the latter situation if we replaced the optical drive appeared, it is likely that the optical drive is caused by different power consumption. We need to understand is that, although the optical drive ATPI interface is the same, but different manufacturers of its pin definition is not the same, if we have a problem with the hard disk cable, it may produce a brand of optical drive to use no problem, but for other brands of optical drive can not work in the case, which requires attention.
9. RESET key quality problems
If the RESET switch is damaged, the internal reed is always in the short position, the host can not power self-test. However, when the RESET switch elasticity is weakened or the button on the chassis is not easy to pop up when pressed, there will be in the process of use, because of the occasional touch of the chassis or in the normal use of the state and the host suddenly reboot. Therefore, when the RESET switch can not be pressed freely, we must carefully check, it is best to replace the new RESET button switch or the chassis of the external buttons for oil lubrication treatment.
There is also a situation where the RESET switch leads in the chassis have too much insulation stripped off during soldering, plus the many times the chassis is unpacked during use can cause the RESET switch wires to be too close together and cause a collision, resulting in the mainframe automatically rebooting.
10. Access to the network card or parallel port, serial port, USB interface access to external devices automatically restart
This is generally due to external faults, such as the printer's parallel port is damaged, a foot shorted to ground, USB device is damaged shorted to ground, the network card is not a standard of workmanship, etc., when we use these devices, because of a sudden short circuit of power supply to cause the computer to restart.
Three, other reasons
1. poor heat dissipation or temperature measurement failure
CPU poor heat dissipation, often the problem is that the CPU radiator fixed card off, the CPU radiator and the CPU contact with the CPU between the foreign body, the CPU fan for a long time after the use of the radiator accumulates too much dust, these conditions will lead to poor CPU heat dissipation, accumulation of high temperature and reboot automatically.
There is also damage to the temperature probe under the CPU or the temperature measurement circuit inside the P4 CPU, and the BIOS on the motherboard has a bug that does not allow for temperature measurement under certain special conditions, which can cause the host computer to reboot automatically during the working process.
Lastly, the CPU protection temperature we set in CMOS is too low, which can also cause the host to restart automatically.
2. Fan speed failure
When the CPU fan speed circuit is damaged or the speed line intermittent break, because the motherboard can not detect the fan speed will be mistaken for the fan stops and automatically shut down or reboot, but we check the CPU fan may be seen to rotate normally, and the speed measurement is normal.
3. Strong magnetic interference
Don't underestimate the electromagnetic interference, many times our computer crash and reboot is also due to interference caused by these interferences both from the chassis inside the CPU fan, chassis fan, graphics card fans, graphics cards, motherboards, hard disk interference, but also from the outside of the power line, inverter air conditioning and even automobiles and other large-scale equipment interference. If our host's interference performance is poor or poor shielding, there will be a host of unexpected restart or frequent crash phenomenon.

The problem must be in the power supply, the computer's power supply is not of good quality, there is no way to steadily switch between them in the event of insufficient voltage, but it might work if you don't use a generator to generate power.
If it doesn't work either, you have to open the case and check the contact of all parts. Is not the main wrench power supply module has a problem or the motherboard capacitors have exploded, of course, more likely to be aging power supply damage, you can use the replacement method, with a good power supply to replace the original, boot and try again. Then there may be a leakage short-circuit problem.

First of all, we talk about the conditions of the Windows system automatically shutdown. In Win98 and later versions of the system support automatic shutdown, that is, not through the power of the physical switch to achieve shutdown. Automatic shutdown is realized through ACPI (Advanced Configuration and Power Interface) technology supported by the operating system (of course, ACPI does more than just automatic shutdown).ACPI was developed by a number of companies, including Intel, Microsoft, and Toshiba***, and allows for power management on top of the BIOS through the operating system. power management through the operating system on top of the BIOS. This technology requires the motherboard controller chip and other I/O chips to establish a standard connection channel with the operating system so that the operating system can perform power management through the Momentary Soft Power Switch (MSPS: Momentary Soft Power Switch). Therefore, automatic shutdown can only be realized if the hardware (control chip), power supply (ATX power supply) and operating system (Win98 or above) all support ACPI technology. Therefore, to ensure that automatic shutdown is realized, the "ACPI fnuction" setting in the BIOS settings must be set to "Enabled"; at the same time, the APM (Advanced Power Management) function must be enabled.
Automatic shutdown is a complex process that is accomplished by the system processes Csrss and Winlogon working together and calling the shutdown function Shutdown Systen, which further calls SetSystenPowerState to shut down the driver and other currently executing program subsystems (e.g., Plug and Play Manager, Power Manager, IO Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, Power Manager, and Power Manager). Manager, Power Manager, IO Manager, Configuration Manager, Memory Manager, etc.). In addition, when performing an automatic shutdown, the system has to check the status of various external devices in the current system as well as the status of applications that have not yet been shut down, and process the data in various data buffers. If an error occurs in the above tasks, the shutdown cannot be performed properly. Therefore, in general, before shutting down the system, you should stop all peripherals and close all applications before shutting down the system.
The Windows system does often fail to shut down automatically, so here are some specific reasons why and how to deal with them.
1. There is a defective auto-shutdown program in the system files. In order to confirm whether it is due to this reason, you can make the following experiments. In the "Start / Run" in the input command "rundll32 user.exe, exitwindows" to see if the normal shutdown.

If you are using other systems (Me/2000/XP), you can also complete the file repair in the corresponding project. If the patch file still cannot solve the problem, you can only reinstall the system. If you run "rundll32 user.exe,exitwindows" and you can't shut down your computer normally, you may have a defective operating system in some of the system programs, but the way to deal with it is still to patch the system or reinstall the system.
2. The virus and some defective applications or system tasks may cause the shutdown to fail. The first step is to check for viruses and close all applications before shutting down the system. Since some applications are loaded at system startup, you can enter the command "msconfig" in the "Startup" menu (in "Start/Run") to subtract the loaded programs one by one. You can subtract the loaded programs from the "Startup" menu (enter the command "msconfig" in "Start/Run") to see if there are any files that affect the shutdown (which will only take effect after a reboot, of course).
3. Peripherals and drivers are not compatible and do not respond to fast shutdowns. In the "Start / Run" in the input command: "msconfig", in the "General" tab, select "Advanced", in the window that opens. ", in the window that opens, select "disable fast shutdown". If you suspect that a peripheral is malfunctioning, you can also uninstall the peripheral to check it one by one, in order to find the affected peripheral.
4. If you have set up a sound file to be used when shutting down Windows, it can also cause the shutdown to fail if the file is corrupted. Please select "Exit Windows" in "Control Panel/Sound/Events" and set the sound name to "None". If you are able to shut down the computer normally after this process, it means that it is indeed due to this reason, and you can reinstall the sound files for use.

If this file is corrupted, it will not appear in the above prompts, but in the form of text prompts: "you can now safely turn off your computer", which may also cause the automatic shutdown failure, restore the file can be.
6. After installing WinXP, you can't turn off your computer automatically. If you exclude the various reasons mentioned above, it is possible that the power options in the control panel are incorrectly set, so please check your settings and make sure that the ACPI and APM are working properly.
