Why does the computer turn off and turn on again

It may be because the user has turned on the Allow the use of the wake-up timer, causing the computer to turn off and sleep until midnight and turn on again, the solution is as follows:

1. First turn on the computer, find and click to enter the "Control Panel" of the computer.

2. In the control panel interface, click to enter "Power Options".

3. Then in the power options entered, click "Change Plan Settings".

4. Then click "Change Advanced Power Settings".

5. After changing the advanced power settings interface, set the "Allow wake-up timer" in the sleep sub-option to "Disable", and finally click "OK".

If the user cannot wake up the computer after turning on the sleep mode, it may be because the computer device driver has conflicted, and it is recommended that the user uninstall the old driver, or because the computer driver is not compatible with the installed hardware, you can replace or upgrade the driver. There is also a possibility that the motherboard BIOS version of the computer is relatively old, you can ** the new version of the BIOS file, and then flash and upgrade the motherboard BIOS.

Most of them are caused by electromagnetic field interference, and you can pay attention to whether you are using high-power appliances or other high-frequency devices near the computer every time you start it yourself.

Shutdown auto-restart.

It should be disable, 2, click on my computer, properties, advanced, settings, turn off the system fails automatically.

Reboot feature. 3. The software is incompatible, which often causes the problem of shutdown and restart, which is a new mechanism of XP.

Solution: Right-click on "My Computer" and select Properties. Select the "Advanced" tab and find.

Go to "Startup and Failback" and click the "Settings" button next to it. Remove "System Failure".

The "auto-restart" checkmark before (if you're using XP only, you can see what you're seeing.)

All checks have been removed so that XP can boot up faster).

4. Enter the safe mode, if it does not restart after shutting down, continue to check the system reason, if it restarts after shutting down, replace the battery.

Source try. How to turn off the auto-restart feature.

windows

XP is an excellent operating system, but sometimes it has a little tantrum, such as self.

Rebooting is an annoying glitch that many people have encountered. Because in the default situation.

Situation, Windows

XP is automatic in the event of a serious failure such as a system or program that stops responding.

Reboot. In order to prevent automatic restart in this case, this function can be disabled. Here's how:

Open "Control Panel", select "Performance & Maintenance" in the category view, "System", and hit.

Opens the System Properties dialog box. Click the Advanced tab, and under Startup and Failback, click the Settings button. Under System Failure, clear the Automatic restart check box.

Click the OK button in front of the box to exit the dialog box.

Note: You must be logged in as an administrator or administrators group member to complete the procedure.

The computer shuts down automatically for no reason.

Suggestion: Reinstall the operation system first to eliminate system problems; Check the settings for CMOS power management; If the CPU fan does not have enough heat dissipation capacity and the CPU temperature is too high, the automatic protection function of the CPU and motherboard will automatically shut down without any reason. power failure; Or the power supply of the host is faulty, and the voltage fluctuates greatly, resulting in irregular automatic shutdown or restart.

Or the voltage of the external power supply is unstable, and the stabilized power supply can be added.

Why does my computer restart for no reason?

If it is restarted for no reason when running games or large software, the main reason is that the power supply is not enough, after all, the number of devices in the configuration is not only large, but also the accessories that consume a lot of power are not small. According to Adam's understanding, the general power supply is to take the peak power of the power supply as the nominal power, rather than the rated maximum power of the power supply, it is recommended to use other 300W power supply to replace the check, to see if the problem is in the power supply.

If it crashes for no reason during a daily application such as surfing the Internet, then it may be that there is some memory problem (if it is not overclocked). You can try to change the location of the slot in the memory, and if it is convenient to find a friend's memory to replace it, check whether it is a problem with the memory itself or the motherboard. Of course, there is also a very high possibility that the heat dissipation of accessories such as the processor or graphics card is not good, which leads to reboot for no reason, and I hope you carefully check the temperature of the processor and other accessories.
