The reason why the computer automatically shuts down when it enters the system, and the laptop autom

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean the CPU fan and heat sink.

dust, add new heat dissipation grease.

If the cooling fan is broken, replace it.

If it's not a problem, it may be caused by problems with motherboard parts or power supplies, voltage instability, hard disk failure, hardware overclocking, etc., and the new hardware is incompatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or try to reinstall it.

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the dashboard.

All Control Panel Items Power Options Change schedule settings Select Turn off the display (select Never or Set time), and select Change computer sleep time.

Select Never or choose the appropriate time (win7 or win8) from the drop-down list next to Make the computer sleep. See if it's caused by the settings above. Sometimes playing games, watching** or large programs will shut down when the card appears, how to avoid the appearance of the computer card will avoid the appearance of shutdown.

I happened to come across it yesterday. You start by switching to a CPU fan.

Try it with another chassis power supply, and it should be solved.

Also see if the capacitor of the motherboard has exploded.

Change the power supply first, try it, if it doesn't work, you can decide that the motherboard has burst the capacitor.

The computer shuts down automatically, why? How to solve it?

Reasons and how to deal with the automatic shutdown of the laptop when it enters the system:

1) The main reason why the laptop system will always shut down automatically is: your CPU fan is stuck (such as too much dust) or the fan is damaged, or the radiator falls off, causing the CPU to not cool down, the motherboard detects that the temperature is too high, when the warning temperature of the motherboard is reached, start the motherboard's self-protection circuit to cut off the power supply, so that it will naturally shut down.

2) Generally, if you encounter such a problem, just open the back cover of the notebook, clean the dust on the CPU fan, if it is damaged, replace the CPU fan, if the radiator falls off for unknown reasons, reinstall it.

Advanced security mode Take a look at the power on press F8 If you can enter the safe mode, the system indicates that there is nothing wrong with the hardware It is caused by a system error or a lost virus, etc. Antivirus or reinstallation (preferred) If the safe mode cannot be entered, it means that there is a problem with the hardware.

1. The CPU or motherboard temperature is too high.

2. Graphics card virtual welding.

You may be caused by this:1Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

3.Power issues. 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.

4.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, it is recommended that you patch the blaster in time after using antivirus software, and the general problem can be solved.

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to kill the virus in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

Be careful: it's your own static electricity. It's better to put it down.

Well, yes, before coming into contact with computer hardware, you should release your own static electricity. When the computer is working, the chassis, monitors and other equipment will release a large amount of static electricity, and the human body also carries a large amount of static electricity, if it comes into contact with the hardware, it may cause the hardware chip to be damaged by breakdown. If your hands are wet and wet, don't touch the hardware, as it is more likely to damage the hardware.

Before touching the hardware, you can touch the metal conductor to release static electricity from your body.

The installation system is automatically shut down, and all kinds of hardware problems are possible.

1. The graphics card and CPU will automatically shut down if they do not dissipate heat.

Second, the memory module and hard disk should be shut down if it is broken.

Send after-sales testing.

Let's check the settings of the dos command

Before installing the system, you must first enter the dos command and make sure that you start from the start...(I haven't been in that situation either).

Try it with the installed version, or the original, without the driver.

==XP and win7's boot mechanism is different.,To install it, you have to install xp first and then win7 and it doesn't seem to be able to install a disk.。 You format the hard drive, repartition it and then install it, and if you have important data, you can use the PE boot disk to copy it out, and if you don't have it, you don't have to reinstall it directly. Hope to adopt.

Your mistake is more serious, and you can't get back. Try the system repair function that comes with win7, maybe there is a silver lining.

One of the bugs is that the system doesn't automatically turn off when you turn off the system (this is also present in some versions of Windows 2000).

Part 3: Let Windows 2000 XP Shut Down Automatically. If you want to go out, but the computer is working again, at this time.

Let's reinstall a system, the next stable, good on the Earth Forum.

If you have a VB, end it with VB.

It will not be 360 antivirus.

Solution:

1. Replace the motherboard.

2. Replace the whole machine.
