Hello, everyone. Lin Fei has come to answer the above questions. Is it normal for the computer to shut down automatically? is it normal for the computer to shut down automatically? many people still don't know. Now let's take a look!

How does the computer often turn off automatically? What if the computer always shuts down automatically? Today, IT encyclopedia will analyze the reasons why computers often shut down automatically and how to solve them.

In fact, there are many reasons why computers often shut down or restart automatically, but the most common reason is that the host computer is too dusty. We just need to take down the mainframe and clean it up. If the problem of frequent automatic shutdown cannot be solved, there may be something wrong with the computer system. We can try to reinstall the system to solve the problem (it is recommended to use the U boot disk installation tool to reinstall the system). If not, it is likely to be a hardware problem. (hardware that may have problems: CPU, memory, power supply, or host cooling issues.)

U Startup Benshaw lists four reasons for frequent automatic shutdown or automatic restart:

(1) the heat dissipation function of the host computer is poor.

(2) unstable power supply or voltage

(3) the reason of computer memory card

(4)。 Problem with the software installed in the system.

Or if the computer shuts down automatically and restarts frequently, it will seriously affect everyone's work and damage the computer more or less. So U Startup Bian Xiao analysis of the problem, to provide you with an effective solution, hoping to help you solve the problem!

(1) install third-party software to be reckoned with.

WindowsXP and Windows2000 startup programs do not run correctly, and then automatically restart the computer, but after repeated reboots, still can not enter the system properly.

Problem: under the default settings of Windows XP and Windows 2000 systems, if a software program does not run correctly during startup, the system will restart the computer again and reload the program. If there is a serious problem with the program, it may cause the computer to restart the endless cycle repeatedly, making it impossible for you to use the computer properly.

Solution: when the computer starts, press F8 key-select safe mode to enter the computer system. After entering the system, open the start menu-Settings-Control Panel-system-Advanced, and then select Startup and recovery. Finally, remove the check box in front of automatic restart in case of system failure.

Computer hardware failure

1. Power supply problem

Fault: there is an optical drive device and a burner device in the computer component. The problem of automatic restart often occurs when two devices are running at the same time.

Fault analysis: although the nominal maximum power of some power supplies can reach 300 watts (300W), the actual power is far from others. In addition, the power of the current computer hardware equipment is relatively large, when a computer has many accessories, the output current of this power supply will fluctuate greatly, which makes the system restart automatically.

Troubleshooting: it is recommended to replace high-quality high-power power supply.

two。 Memory problem

Fault: the memory used for computer assembly is large memory, which usually runs normally. But when running large 3D games or software that requires a lot of memory, it often restarts automatically.

Fault analysis: due to the insufficient quality of some large-capacity memory, the system often restarts automatically. And many motherboards on the market support dual-channel memory. If the quality and performance of the two memories are different, it may cause the system to work unsteadily. When you need to run a larger game or software, the system will suddenly restart automatically.

Troubleshooting: we set the memory "CL value" to 3 or 3.5 in the BIOS setting to appropriately reduce the "FSB bus frequency" of the system. If the memory works in dual-channel mode, it is recommended to buy the same brand of memory, so as to ensure the balanced and stable operation of the same performance.

3. There is a problem with the Power button and reset button on the surface of the chassis.

Fault performance: the computer shuts down suddenly or restarts automatically from time to time. You need to press the Power button or reset button on the computer chassis several times, or tap the front panel of the chassis to prevent failure.

Fault analysis: this problem is a hidden fault and takes a long time to detect. However, this kind of failure usually occurs on the computer for a long time, usually due to the weakening of the spring on the start button and restart button on the host, or the abnormal position of the button caused by a large amount of dirt in the front panel and chassis of the button. resulting in automatic restart or automatic shutdown failure.

Troubleshooting: when the shutdown and restart buttons cannot return to their normal position, IT Encyclopedia recommends that you consider replacing the button assembly or cleaning the dirt between the button and the chassis panel with alcohol.

Other factors.

1. The BIOS setting of the motherboard is confused or improper.

Failure: when a large game or software runs for about 10 minutes, the system shuts down or restarts automatically, IT Encyclopedia initially suspected that the CPU temperature was too high, but the software test showed that the CPU temperature was within the normal range.

Fault analysis: at present, many motherboards have built-in control chips, which can automatically control and monitor CPU temperature, and shut down automatically when the temperature is too high. However, if the warning temperature value for BIOS is set too low, the computer will automatically shut down.

Troubleshooting: enter BIOS settings and set "pc h"

2. The problem of the patch board

Fault performance: the host computer is connected to a power plug board with printers, scanners and speakers, and it is easy to restart automatically when the weather is humid.

Fault analysis: in general, we will use the plug board to power multiple computer equipment at the same time, but when the quality of the plug board has been used for a long time, the elasticity of the spring of the Jack is weakened. at the same time, it will also lead to poor contact between the plug and the spring due to corrosion and oxidation, resulting in the volatility of the current, once the current can not effectively ensure the stable operation of the system. Then there will be the problem of sudden automatic shutdown.

Troubleshooting: often check the plug board, buy a better quality brand plug board, use for a long time to remember to replace.
