Find a software that can only be turned on for a few hours a day and automatically shut down

Use the shutdown command.

Or use the Lucky Star Timer Shutdown Software |You can set how long the power can be turned off and then it can't be turned on again.

You search for automatic shutdown software on the Internet, which has how long after booting up automatic shutdown, and you can also set a password, you try to find a cracked version.

There is an auto-shutdown command that you can enter when he turns it on.

In Start-Run, enter:

shutdown -s -t 7200s

It means that it will automatically shut down after 7200 seconds.

I do have a software that sets the system to turn on automatically and turn it off automatically.

However, there is no password setting, and the others are useless once they pass it.

Besides, if it's turned off by the software, just reboot it.

Unless you have to add a login password.

Find a timed shutdown software on the Internet, put down the startup item, run it when it is turned on, and shut it down for 2 hours

Search boot control software.

Just get a software that shuts down the computer at a scheduled time.

1.: Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will cause the computer to shut down automatically, it is recommended to check whether the system temperature is normal.

2.: Memory reasons. When the memory is in contact with the motherboard plug-in slot, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard, or you can change the socket to see if it is down?

3.: Power supply issue. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

Software factors. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down. If you are using Windows

2000 or Windows

XP system, it is recommended that you use antivirus software to patch the blaster in time, and the general problem can be solved.

The computer shuts down automatically for no reason.

5: Check whether the CPU is overheating and whether the CPU fan tray is stable, if it is broken.

Or it is unstable, can't suppress the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature hole is too high, the automatic protection function of the motherboard will automatically shut down, and the screws of the CPU fan are loose and early!

6: The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so you can replace it.

7: When the power supply of the host fails, or the voltage fluctuates greatly, add AC regulated power supply.

8: No, it is recommended to disinfect in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

It's possible that there is too much dust on the fan.

Causes automatic shutdown.

It's normal to clean up the dust!

The temperature of the main unit is too high, and it will be after overheating.

Card machine. etc.

The driver problem, the installation is incorrect, and it has been starting when it arrives, and the brother of Zhan Heng Nai uses acres to do the program resulting in a jam.

Clean up useless programs, optimize the system, and so on.

If the hardware is not in good contact or there is a problem with the memory and hard disk, it is recommended to send it for repair.

It may be caused by the CPU or graphics card overheating, check how the heat dissipation of the chassis is, and whether the CPU fan and the graphics card's fan are rotating.

One is that the battery doesn't have much power.

The second is that the mobile phone battery is not good.

The third is that your phone's memory does not support such large-scale games.

After about half an hour of turning on, it has to be automatically shut down, just like a power outage. The hard drive shuts down with a "pop". Hello at start-up, shutdown is mainly caused by insufficient power supply power or high hardware temperature 1The power of the power supply is not enough to replace the power supply.

After powering on, pay attention to the CPU temperature and whether the power supply is too small. If the CPU overheats due to poor heat dissipation, it will cause a shutdown.

Is there an automatic shutdown or restart?It is recommended to check it first, I can't find the root of the problem, and it's troublesome to change it. Seek adoption.

In the case that the operating system is not set to shut down automatically. Then it should be that you installed some software or were hacked.

You use Master Lu to check the temperature, whether the temperature is too high.

The temperature is too high, clean up the dust, apply silicone, and if it doesn't work, replace the fan.

Is the power saving mode set?

No, but it's easy to do. Generally, it is only the virus that goes back to use.

There are a lot of software for automatic shutdown on the Internet. You can go to the next one yourself.

The software is there!However, most of it is paid software.

You can refer to. Timed shutdown.

A simple way to implement a scheduled shutdown under Windows XP.

Specify that the system will automatically shut down after 22 minutes: click "Start Running", enter the command "shutdown s t 1320" in "Open" (note: quotation marks are not entered, there are spaces between parameters, the unit of 1320 is seconds), click the "OK" button.

To specify that the system will automatically shut down at a certain time (e.g., 12:00), enter the command "at 12:00 shutdown s" in "Open".

To cancel the scheduled shutdown, enter the command shutdown a in the Open field.

The above functions are implemented using the "shutdown" command, and the shutdown parameter is entered "shutdown" in the command line window. The author thinks that the most useful is the "i" parameter, which can bring up the "remote shutdown dialog box", which can easily realize the remote shutdown of the computer in the local area network.

Do you have to make sure that the black screen is a shutdown first? Is the main chassis still operational? The fan didn't have much of an impact... Unless it's overheating because of the fan.

Is it a laptop or a desktop computer? If it's a desktop computer, check if the CPU fan is running.

There are several reasons why the computer always shuts down automatically 1The case heat dissipation is not good, resulting in internal overheating and automatic shutdown Many friends' computer automatic shutdown is likely to be affected by the hot weather, if the chassis heat dissipation is not good, resulting in the motherboard, CPU temperature is too high, it will cause automatic shutdown. It is recommended to go to the BIOS to check whether the system temperature is normal.

2.If you have carried the computer, or shaken the case, it is very likely that the memory module will be loose, and this problem is to open the case and plug in and unplug the memory module again (remember to erase the "gold finger" with an eraser by the way). 3.

The power supply of the computer is insufficient, the power supply is insufficient due to the automatic shutdown caused by the voltage instability, or the voltage is unstable. If this problem occurs, it is necessary to check whether the high-power graphics card hardware is inserted, and the power of the power supply is not high, resulting in the system not being able to withstand automatic shutdown. There is also a voltage problem, which is caused by voltage instability in some places, and it can be solved by adding a voltage regulator.

4.Software: If the software is automatically shut down due to system reasons or software compatibility, poisoning, etc., many viruses will cause automatic shutdown.

There are also software compatibility issues, so if it doesn't work, try reinstalling the system or upgrading the system. There is also a hardware driver, it is best to check and upgrade.

It feels like it's most likely the software settings. If you can't solve the problem yourself, the software recommends that you consider reinstalling the system. There is also the issue of hardware.

The power consumption of the power supply is insufficient. This is also prone to such a situation. It can damage the hardware for a long time.

It's not a simple hard disk (the lack of power consumption is generally a problem with the assembly machine that you configure).

A: Based on your question, there are three possible reasons for this:

1. The load capacity and output current stability of the power supply are not good: it will cause the system to work unstable, and cause irregular restart, because some files of the XP operating system are damaged during abnormal restart, so it will shut down.

2. Hard disk has bad sectors: If the hard disk has bad sectors, it will often crash or restart when the system is working, and bad sectors on the hard disk will also cause system file damage.

3. Motherboard is faulty: If there is a fault in the motherboard, such as a failure of the IDE control part, which causes file damage or loss while working, Windows XP will also prompt you to back up the system.

Through the above several reasons, I recommend that you use the troubleshooting method to troubleshoot, first replace a stable performance, strong load capacity power supply to see the status, if not, you may need to replace the hard disk and motherboard. If you have enough time, you may wish to reformat the hard drive partition and reinstall a healthy Windows XP operating system to avoid the above failures caused by system software problems.

It may have something to do with the unstable power supply in your home. The power supply voltage decreases during peak usage, and if your chassis power supply is voltage sensitive, it will automatically shut down.

Open the case to see if your CPU fan still rotates, if the temperature is too high, it will automatically shut down, and if the speed is not enough, it will also cause automatic shutdown, it is recommended to change the fan, and the better ones will be dozens of optical oceans.

The power supply is aging, try changing the power supply.
