My desktop computer turned on and shut down automatically within a few minutes

Poor heat dissipation...! Check that the various fans have turned up for ......

The problem of the desktop automatically shutting down after a few seconds of turning on should be judged according to the phenomenon of "shutdown".

If the system is turned off, it will be in a normal shutdown state, that is, the system prompts "Shutdown". It is recommended to check the CPU cooler (fan) and check the operating system.

If the power is turned on for a few seconds, it will be powered off and shut down. Determine if it is a problem with the host power supply or the motherboard. It is recommended to change the power supply test to rule out the possibility of power supply problems.

Inspect the devices on the motherboard, mainly to check for problems such as large capacitor bursts. This can also be tested by attaching the card to another motherboard.

Again, check the CPU pins to see if there are any "burned" pins.

There are a variety of reasons that can cause the computer to shut down automatically, common fault analysis, such as:

1.The computer CPU has poor heat dissipation and high temperature.

2.Computer power supply failure, 3The failure of the computer motherboard and parts may lead to the phenomenon of automatic shutdown after the computer is turned on

Clean the inside of the computer.

Remove the motherboard button battery, discharge it for 5 minutes, remove the memory module cart, wipe the gold finger part, reinstall it in place, and boot it for testing.

If it has not returned to normal, you can replace the power supply for testing, if the individual has no experience in computer repair!

It is recommended to send it to a local computer repair shop for testing and repair!

Hello, I'm glad to serve you, the computer host will automatically shut down after a few seconds of booting, in this case, the computer can not be turned on, for this kind of failure, the first step is to reinsert the memory module, the most important thing is to re-erase the memory strip gold finger area with an eraser, most of the reason why the computer can not be turned on is caused by poor contact with the memory module, there is also a situation that the motherboard chip can not be turned on due to a short circuit, the motherboard chip short circuit will be repaired at the chip level, this needs to be operated by professionals, Try reinserting the memory module first. Hope mine is helpful to you!

1.The first reason: the power supply of the host is faulty, such as the filter capacitor of the power supply is bulging and leaking, resulting in insufficient power supply, the computer will automatically shut down or restart, and the treatment method is to replace the power supply.

2.The second reason: The video memory integrated block of the graphics card is soldered, which causes it to automatically shut down after powering on and having poor contact with the motherboard PCB.

3.The third reason: the radiator fell off, and the motherboard detected that there was no cooling device, and the computer automatically shut down due to the start of protection. Jianyi.

4.The fourth reason: the boot circuit of the motherboard is faulty, there is a problem with the power supply of the special CPU, the CPU cannot be started, and the motherboard is started.

This can't guess your fault from such a description, it can only tell you that there is a high possibility of hardware problems, and it should not be a big problem, but the possibility of bad contact or poor heat dissipation is relatively large.

There are many reasons for this, such as:

1. If the CPU overheats, the motherboard will automatically protect it.

2. The inside of the chassis with poor heat dissipation is overheated.

3. If there is a problem with the system, it will shut down by itself.

4. Other problems, such as memory instability, etc.

If the desktop computer turns on for a few seconds and shuts down automatically, this situation is still relatively related to the motherboard, and it is recommended to go to the computer company to replace the accessories to detect the problem.

There may be several reasons for the automatic shutdown after a few seconds of booting, the first system problem, a Trojan horse or the like, it is recommended to kill the poison, and the second is a power supply problem, the power supply is insufficient due to the aging of the power supply, and the power supply can be replaced to solve it. Third, the CPU fan heat dissipation problem, see if the temperature will be too high, if it is too high, it will automatically shut down for protection, and replace the fan with strong heat dissipation ability.

Look at you, this problem is probably caused by poor heat dissipation of the CPU fan, it is possible that one of the four buckles is broken or there is too much dust and the heat dissipation is not good! It is recommended to clean up the dust of the fan Remove the hot silicone on the fan, check if there is any buckle breakage, if there is a replacement fan, it can be solved! If these are all good, try a different memory!

If you really can't do it, please repair the computer master to test it!

First use the elimination method first of all, it is not a problem with memory, if there is a problem with the memory, you can't turn it on, it's not a problem with the motherboard hard disk, the hardware is all together, if there is a problem with the motherboard or hard disk, you can't get into the system, it's not a problem with the graphics card, if the graphics card has a problem, it's a black screen playing games and a stripe on the desktop, that's the problem of your power supply, the power supply doesn't work, sometimes it shuts down directly after turning it on, and sometimes it shuts down after a short time of booting. Change the power supply.

As you described, this situation is usually caused by a certain hardware of the computer, you can open the computer case, plug and unplug the memory module, and then feel whether the graphics card is overheated, check whether the CPU contact is strong, whether it is overheated, I hope mine is helpful to you.

This should be the fault of the computer hardware, it is recommended to check the fault of the power supply and motherboard, and you can go to the after-sales service to deal with it.

Possible causes of automatic power outages:

First, after automatic shutdown If it can be turned on normally, then this situation belongs to the self-protection function of the system.

When the computer is overloaded or encounters other conditions that damage the CPU or system, poisoning, CPU usage is often 100 and so on.

In order to protect the CPU from damage, the system automatically loses power. It is recommended to optimize the system.

Second, poor heat dissipation, which generally occurs when the CPU is overheated or the CPU is overloaded due to the long-term operation of the computer. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function. If this is the case, you need to clean the laptop fan, radiator.

3. Automatic power failure caused by external devices, removal of newly installed hardware devices, such as external cameras, printers, including upgraded memory, etc.;

Fourth, the hardware itself is faulty and needs to be specifically detected.

First of all, it is recommended to upgrade the anti-virus software after going to the desktop, check and kill computer viruses, and then there is a comprehensive cleaning of the computer dust.

The automatic shutdown of the computer is mainly caused by the following reasons:

1.Poor heat dissipation. Due to the influence of weather temperature (it is winter to rule out environmental problems) or the system overheating caused by insufficient revolutions of the CPU fan, 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 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 that causes the computer to shut down automatically.

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.

Try to change the disc, secondly, check whether the power cable or data cable of the optical drive is connected, if it is okay, it is a problem with the optical drive.

There are many reasons for automatic shutdown: First, poisoning. 2: The motherboard is aging and shut down. Three: The CPU temperature is too high. It depends on what kind of situation you have.

Auto shutdown is a command from the computer. The common ones are the automatic shutdown of windows, and the automatic shutdown of the embedded system mobile phone system. Specify the time when the computer automatically shuts down command:

at 23:00 shutdown -s"Countdown computer auto shutdown command:" -s -t 3600"Cancel Auto-Shutdown Command:

shutdown -a"。

Maybe the motherboard battery is dead.

Hello answer, I have seen your question, I am speeding to answer, please wait for me for a while! 5. Another big reason for the automatic shutdown of the computer is that the voltage of your computer is unstable, so it is recommended to try your computer on another occasion. If the voltage is okay, you can try to change the power supply of the host, if the power supply of the host is still invalid after changing, it may be that your motherboard has been broken down by the voltage.

I had to change the motherboard.

The above is how to deal with the sudden shutdown of the computer after a while, I hope it will help you!

Computer poisoning is usually solved by reinstalling the system, and the anti-virus is sometimes not complete.

Of course, when reinstalling the system, you need to format all partitions to ensure that there are no viruses left.

In terms of system: the corn system is relatively easy to use, not only stable, but also very smooth.

The reason for the occurrence of "desktop computer automatically shuts down after a few seconds of turning on" is:

Situation 1: If there is an automatic shutdown when you do not enter the system, it is a hardware problem.

Solution: It is recommended to clean up the dust with a hair dryer for all kinds of fans in Zaihe, uncover the dust paper in the center of the fan, drip a few drops of cooking oil, lubricate it for a while and then cover it.

Unplug the memory and hard disk and check the golden hand Kaiqi pins (contact pieces) with an eraser. It can generally be solved by turning on the computer and running the staring game.

If it doesn't work, it may be a problem with the motherboard, and it can only be sent for repair.

Situation 2: If the computer is shut down after entering the system.

Solution: Press it when it is turned on"f8", click Use last correct configuration to enter the system.

Situation 3: If the CPU temperature is too high, the computer will automatically shut down in order to protect itself.

Solution: Turn off the power and turn it on after 30 minutes.

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, add new heat dissipation silicone grease, if the heat dissipation fan is broken, change it. If it is not a problem, it may be caused by problems with motherboard parts or power supply, voltage instability, hard disk failure, etc., and the new hardware is not compatible. 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 control panel All Control Panel Items Power Options Select Turn off the monitor (select Never or Set Time) Select Change the computer sleep time on the left, and select Never or select the appropriate time (Win7 system) from the drop-down list next to Make the computer sleep.

See if it's caused by the settings below.

The answer may be due to a computer hardware failure, first try whether it can enter the safe mode, if it is still automatically shut down in the system security mode, you can explain the hardware reason; If it doesn't shut down, there may be a problem with the system, and you can scan for antivirus in safe mode;

Ask how to enter safe mode.

Ask questions and then what.

Asking questions is still not good for killing the virus.

1.Poor heat dissipation, power failure, and motherboard failure may cause the computer to shut down automatically or restart repeatedly. (Reboot is an important feature: sometimes it shuts down, sometimes it restarts).

First of all, check whether there is a problem with the hardware, focusing on the power supply of the motherboard, CPU fan, host power supply, and power socket.

The computer automatically loses power, and if this happens, you can try the following methods to solve it:

1. It may be that the power supply is unstable, the voltage is not enough or it is broken, and the new power supply is replaced.

2. The motherboard power supply is in poor contact, and ensure that the motherboard lines are in good contact.

3. The CPU has poor thermal conductivity, overheating, the CPU fan does not rotate or the speed is slow or even broken, replace the CPU fan, coat the CPU with thermal conductive silicone, do not coat it too thick.

The automatic shutdown of the computer is generally a hardware problem, such as poor memory contact, loose power cord of the hard disk, etc.

If you can't fix the problem of automatic shutdown like this, you can't move it, but it will expand the problem, so you should ask a professional to repair it.

See if the temperature is too high and it will shut down automatically.

1. Medium virus.

2. The fan heat is not good, and the temperature is high.

3. Improper settings.

4. Problems with power supply.

I just met du two days ago about this question!

Don't worry, it's actually very simple to solve it.

The above answerers replied that it was too general, and the whites would not know where to start Follow my method:

Do the following two steps within 15 seconds of booting: 1. Press F8, 2, press F2+Alt Then the computer will enter a selection interface (at this time, it will no longer automatically shut down), press the up and down arrows to have two options, select the upper one ......3m-st 3320418……(This is the hard drive) and then press enter, at this point the computer enters the boot, and it's OK!
