Changhong LED29B3100c will automatically shut down after powering on

Reason for automatic shutdown of the computer:

1.viral causes;

2."Automatic shutdown and restart when the computer encounters a serious error" is enabled;

3.Severe memory errors causing the system to crash (software issues);

4.Malicious program or **.

Phenomenon: During the normal operation of the computer, the system suddenly and automatically shuts down or restarts the system.

Phenomenon analysis: Today's motherboards have a temperature monitoring function for the CPU, once the CPU temperature is too high, exceeding the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the relevant hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.

Solution: If the above sudden shutdown phenomenon keeps happening, check whether the heat dissipation of the CPU is normal. Turn on the case to see if the fan blades are working properly, and then enter the BIOS option to see the speed of the fan and the working temperature of the CPU.

If you find that it is a fan problem, you will carry out relevant dust removal maintenance on the fan or replace it with a better quality fan. If you rule out the hardware cause, enter the system, overwrite the installation power management from the installation CD of "Windows", and then thoroughly check and kill viruses. When these factors are eliminated, the cause of the failure may be the aging or damage of the power supply, which can be confirmed by replacing the power supply method, and replace it with a new one if the power supply is broken, and it must not be used continuously, and the hardware will be burned.

The copper sheet on the battery plate may be dirty, wipe it with an eraser. It could be good.

If this problem occurs, generally speaking, it is not good to deal with Oak Zheng, if you are in the warranty period, quickly contact customer service to deal with the old such as selling to solve.
