The WinXP computer has no reason to shut down the solution.

The computer automatically shuts down for no reason, and needs specific analysis. Recently, users who use the WinXP system suddenly shut down automatically when using the computer. what happened? When we encounter such a problem, how should we solve it? The following small series will tell you about the WinXP computer solution for no reason to shut down.

The steps are as follows:

First, the hardware:

1, power supply:

With the increasing number of peripherals, the original power supply of the computer Power is not enough, such automatic shutdown failure is still very common.

Solution: Unplug unused peripherals, reduce the power supply, or replace a larger power supply.

2, the voltage is unstable:

The switching power supply of the general household computer has a working voltage range of 170V-240V. When the mains voltage is lower than 170V, the computer will automatically restart or shut down. Because the voltage fluctuations are not clearly perceived by the user, it is mistaken for the computer's inexplicable automatic restart.

Solution: For areas with unstable power supply, you can purchase UPS power supply or 130-260V wide-amplitude switching power supply to ensure a stable working environment.

3, poor contact between the power plug and the socket, is also one of the reasons for the computer automatically shut down, especially the user who plugs and unplugs the power every time the switch is turned on. The probability of such a fault is relatively high, long-term plugging and unplugging It will cause the contact piece to loosen, so it is better to use the tow board with switch, it is better to plug and unplug the power plug, just turn off the power switch.

4, there is a part, is the problem of the computer power switch button and reset button, if the power switch or reset button is damaged, it will also automatically shut down when you occasionally touch the chassis or use the computer normally. problem.

5, with the popularity of large-scale games, the beautiful picture on the graphics card is also higher and higher, because the graphics card temperature is too high and cause automatic shutdown is not a few, you can use monitoring software, if a certain A device can automatically shut down because of high temperature, and can take corresponding measures to cool it. If it is a desktop computer, you can add a graphics card fan to alleviate the problem of excessive temperature.

6. If it is a laptop, you can Use measures such as a dedicated ventilation base for notebooks.

7, some hardware devices have the option of automatic shutdown, check whether the device in this computer is selected to automatically shut down? The boot button enters the BIOS to check whether there is a wake no lan for S5 in the sub-item. This is the NIC with wake-up function, set it to disable. Can I also check if the wakeup function of the network card is turned off in the device manager? Start → control panel → device manager & rarr; NIC adapter & rarr; attribute & rarr; advanced & rarr; wake up settings & rarr; set & ldquo; no & rdquo; & rarr;

8. If you have used a laptop for more than one year, and you often have an automatic shutdown or an automatic restart, you can consider opening the back cover of the chassis and cleaning the dust around the ventilation channel. First of all, you must remove the computer's power supply or lithium battery, and your hands should take anti-static measures to prevent static electricity from damaging the delicate electronic equipment. The hand-cranked extractable fan carefully cleans the dust. If the fan is noisy, you can drop one or two drops of lubricant in the center shaft. If you have poor hands-on ability, you do not need to disassemble the fan. Just carefully remove the dust from the air outlet and the air inlet and the ventilation passage. Desktops may have a longer cleaning cycle because of the larger space.

Second, the software failure:

1, first to the power manager to see if the automatic power-off mode is set, if so, change to a longer time, or set to Not also. Start → Control Panel & Rarr; Power Options & Rarr; Power Usage & Rarr; Turn off the monitor, turn off the hard drive, system standby & rarr; never →

2, can observe the beginning & rarr; all programs & rarr; start & larr; here is a bad program for regular shutdown? Then, look at the start → control panel → planning tasks have a delay shutdown program? (Some users will be given scheduled tasks for delayed shutdown).

3, there are some software automatic shutdown program, to see if you accidentally selected this do not need Dongdong? For example: Thunder has this shutdown option, the specific steps are: Intelligent download &rarr in the lower left corner of the Thunder panel; After downloading → Shutdown, standby, exit Thunder and other options, if you accidentally check the shutdown option will automatically shut down.

4, such as Baidu cloud has the option to automatically shut down after downloading large files, if it is delayed, it will automatically shut down.

5, in addition to Thunder software has automatic shutdown function, more common anti-virus software, express, BT download, video playback and so on. In the software settings, there are actions to automatically shut down after completing a task. But the general default setting is off. The purpose is to automatically shut down the computer after completing the task when running a more time consuming operation.

6, update driver: right click on my computer → management & rarr; device manager & rarr; computer & rarr; right click on ACPIUniprocessor PC & rarr; update driver & rarr; install from the list or specified location (advanced) & rarr; Next → don't search. I have to choose the driver → next → select Advaanced Configuration and Power Inerface (ACPI) PC→ next step, until the end of the device driver replacement, restart the computer.

7, registry settings: set in the registry to avoid unwarranted automatic shutdown. Start → Run → Enter: regedit Enter to open the registry, navigate to the following location: HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon Change the right key value: PowerdownAfterShutdown to 1 (double-click this key value, which will Change the value data to 1) Refresh (F5 key) to take effect.

8. Finally, the key files of the operating system are lost, and the system will choose to automatically shut down because it cannot continue to run.

The WinXP computer has no reason to shut down the solution, so I will introduce it to you in detail. Generally, the computer automatically shuts down for no reason, and there is definitely a reason, otherwise it will not automatically shut down! First check if the hardware or software causes the computer to shut down.
