What s going on with the frequent automatic shutdown of computers in Internet cafes

Analysis and answer to the problem of automatic shutdown of the computer:

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 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 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 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 use antivirus software to solve the general problem.

5: Check whether the CPU is overheated, whether the CPU fan tray is stable, if it is broken or unstable, it can't hold down the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature is too high, the automatic protection function of the motherboard will automatically shut down, and the CPU fan screws are loose and early! There is another important reason, the CPU fan silicone grease is gone, just add silicone grease.

6: It may be caused by the unstable voltage of the host, and it can be replaced.

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

Troubleshoot system issues. It may be that there is too much dust on the fan, which causes it to shut down automatically, and the solution is to clean up the dust and it will be normal!

The solution to the automatic shutdown of the computer while it is running.

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

Because there is an automatic power-off protection function in the motherboard BIOS settings, that is, when the computer is overloaded or encounters other situations that damage the CPU or system, this information will be fed back to the motherboard chip in time and react, because the BIOS is set up with this protection function, so in order to protect the CPU from damage, the system will automatically power off.

Your computer should be cleaned of dust or the fan is not running well, which usually occurs when the CPU is overheated or the CPU is overloaded due to the computer running for a long time. 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 that's the case, just fix the heat dissipation problem!

1.Take out the battery of the motherboard, buckle it back, and discharge it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2.Sweep the dust inside the chassis to eliminate short circuits or poor heat dissipation caused by excessive dust.

3.See if the CPU thermal grease is dry, silicone grease is used to improve heat dissipation capacity, if there is no silicone grease, the heat may not be dissipated, and the machine will automatically shut down. Note:

If there is too much thermal grease and it is too thick, it will form a film in the middle of the contact surface, which will hinder the direct contact of the metal, which is worse than not applying thermal grease.

4.Think about it, is the fan size or fan power enough for a high-end computer? First consider the size of the fan (the bigger the better), then the power (the bigger the better), and the manufacturer.

5.Other objective reasons, such as unstable voltage fluctuations, interference from other electrical appliances on the same power supply line, high indoor temperature, long-term running of large programs (games) when booting up, poor heat dissipation of the case, poisoning, CPU usage often 100, etc. You can install Windows Optimizer, in addition to the software can comprehensively clean and optimize the system, it can also detect all hardware and software information of the system, you can detect it at any time, and compare it with the previous information, from which you can find problems.

If the computer cannot be turned on normally after power failure, it is estimated that there is a problem with the hardware or system files.

First, use the replacement method to troubleshoot the hardware problem (mainly check the motherboard and power supply).

After the hardware is eliminated, it is a system problem, and it can only be solved by reinstalling the system.

Frequent automatic power outages can cause harm to computer hardware, and the consequence is to shorten the life of the hardware.

The reason for the automatic shutdown of the computer is either hardware or software:

1. CPU and power supply fan failure (the fan does not rotate, it will restart when it is turned on, or it will restart after a while after turning on).

Solution: Replace the CPU or power fan, and add some silicone to the CPU when necessary;

2. Virus Trojan damage, when the core components of the system are damaged, the running computer may automatically shut down.

Solution: It can be detected and killed by some anti-virus software such as 360, Kingsoft and Little Red Umbrella (only one anti-virus software can be installed on a computer);

3. In the running software, there are some software with the option of shutting down the task to complete, which may have been set inadvertently.

Solution: For example, some software advanced settings such as Thunderbolt, BT, Storm, PPS, etc., will have the option of automatic shutdown;

4. Poor heat dissipation, power supply failure, and motherboard failure may cause the computer to shut down automatically or restart repeatedly.

Solution: Open the chassis to clean up dust, check the aging of the circuit, etc.

If you can't do it, it is recommended to find a professional or repair shop to solve the problem.

I hope my reply is correct and you will be of help !

The possible scenarios are:1Whether the CPU is overclocked without paying attention to heat dissipation.

2.Whether the memory is too small,512MBXP can run completely smoothly,256M although it is OK,But after loading a few startup items at boot,Run a few programs,Open a few web pages,The memory has been taken up almost,If you play again

3.The temperature inside the chassis is too high.

It may be caused by the graphics card, or it may be the CPU....

Errors can also occur when the hard drive overheats. There are also motherboards, memory, etc.

Presumably an issue with the graphics card or graphics card driver.

There are many reasons for the blue screen restart of the computer.

1. The graphics card is too hot.

2. Viruses. 3. The CPU is too hot.

4. Too much dust, etc.

The computer automatically shuts down after just half an hour of surfing the Internet, what's going on?

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, and add new heat dissipation silicone grease. 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 Turn on hardware and sound Power Options Select Turn off the monitor (select Never or Set Time) Select Never or select the appropriate time from the drop-down list next to Make the computer go to sleep (Win7).
