How does the computer always turn off the machine automatically?

The computer always shuts down automatically the processing method one

There are a number of reasons why a laptop shuts down automatically, such as a motherboard, a hardware failure in a power supply module, or a battery failure. You can first remove the battery to confirm that it is connected to the battery.

Another important reason is that there is a problem with the internal cooling system in the notebook computer, the high CPU temperature will cause automatic protection shutdown.

Automatic Shutdown Troubleshooting Method:

1, there may be a problem with the BIOS setup, enter the BIOS to restore the default settings or the motherboard of the battery to take out, reverse-buckle discharge, and so on 5 minutes in reverse loading can be. Objective: To restore the default values for BIOS settings, and to troubleshoot the automatic restart or shutdown of the BIOS's thermal presets.

2, if the computer in the use of an application software occurs automatically shutdown, the automatic shutdown failure may be caused by this program software, the general program software uninstall can be.

3, then check the power supply, power quality is poor, aging or power too small, can not meet the power requirements of computer accessories, can be replaced by high-power high-quality power supply, if troubleshooting, it is the power caused by the automatic shutdown failure.

4, then use the elimination method, check memory, video card, CPU, CPU fan, motherboard and so on.

5, check the memory, the quality of memory does not pass, heat dissipation, overclocking, different brands of memory mix and the CAS value set too low can cause computer automatic shutdown, available test memory, and the BIOS in the memory parameters are adjusted accordingly.

6, check the motherboard, motherboard aging, capacitor failure or slurry, motherboard power pins, motherboard and chassis backplane can cause automatic shutdown, the motherboard can be removed from the chassis check or test, and then check the CPU fan rotation and CPU temperature is normal, and then check the CPU fan heatsink bottom silicone is dry, If it dries, clean the silicone on the CPU fan and then paint the silicone again. If the fan is not normal, replace the CPU fan.

7, cleaning method: It is through the computer mainframe parts of the dust cleaning to eliminate the failure of the method. Dust is also can cause computer automatic shutdown failure of one of the factors, dust can cause parts aging, pin oxidation, poor contact and short-circuit and so on. For these faults caused by dust, it is more effective to use the cleaning method generally.

8, the power supply system is not stable, can also cause automatic shutdown failure, you can consider the configuration of a voltage regulator with the power supply of UPS.

The computer always shuts down automatically the processing method two

Reason Analysis:

1. Host heat loss, power supply failure, motherboard failure, may result in computer automatic shutdown or repeated restart automatically. (reboot is an important feature: sometimes shutdown, sometimes reboot)

2. Virus Trojan damage, when the system core components damaged, the computer is running may automatically shutdown. Jinshan security experts here, to provide you with special kill tools and system repair tools, please click on the fast download.

3. In the running software, there are some software with the task to complete the shutdown option, may not be noticed by the user, the switch turned on.

These software is more common, such as thunder, Express, anti-virus software, BT download, video playback and so on. In software settings, there is an automatic shutdown action after a task has been completed. However, the general default setting is off. The goal is to automatically turn off the computer when the task is completed by running more time-consuming operations.

4. Other hardware reasons.

Solution:

1. First check the hardware is not a problem, focus on the motherboard, CPU fan, host power supply, power outlet is not a problem.

2. Check if there are some application software tasks completed after the shutdown was enabled. It is obvious that it can be seen. The feature is that before the shutdown, there will always be a program to run, usually play a dialog box to remind the shutdown.

3. Solve the virus trojan, repair system damaged files. Using the latest version of Jinshan Poison PA can complete virus cleanup and system configuration repair at once.
