Computer power-on automatic power failure Reason

　　Power down failure can also occur for several reasons:

first, there are problems with the chassis power switch, such as Reset spring failure,

The second is the overclocking of C p u, or the C P U fan is having problems.

Third, the optical drive and other accessories have short circuit fault.

　　Computer power-on automatic power failure One:
failure problem: Turn on the power switch, press the power-on button, fan turned, the machine has movement, after a power outage, the fan does not move, the light is not bright, and then press the key is useless. The power is turned on, after a while, reboot and repeat the above situation. And I dial the hard drive power, can boot to detect the hard drive without this step. Then the optical drive power to clean up, in a burst of Hu, you can turn on the normal function one day (no longer do not shut down the machine). Excuse me, I don't want to do this every day, how can i solve this problem?

Failure Analysis: This type of automatic power off after the situation is likely to be a power supply or motherboard failure. Fault causes are diverse, such as IC chip, capacitor burned, a circuit problems, such as, in general, such a failure of the individual is not able to repair, recommend the repair or replacement of related accessories, it is recommended to first try to replace the power supply. In addition, the power supply quality problems (such as low voltage, abnormal fluctuation, etc.), may also cause this power off the fault phenomenon.

　　Computer power-on automatic power failure Two:
trouble: The computer turns off automatically after 10 seconds of booting. CPU and so on has cleaned up the power should be no problem because before using another computer hardware test can be normal boot, excuse me what is this situation?

Failure Analysis: The CPU temperature may be high, it is recommended to download the CPU temperature test software is not the CPU problem, and then consider whether to change the fan or add silica and other issues!

　　Computer power-on automatic power failure Three:
failure Problem: My computer has been on the power of the recent power-on also do not know how to do, before the good, the recent temperature drop has often occurred in this situation, is how it?

Failure Analysis: temperature reduction is likely to cause some of our problems, we suggest that you or the computer chassis to open, the inside can plug the things to remove the installation, to see if the problem can be solved.

In general, the problem is most likely a power supply or motherboard failure. Fault causes are diverse, such as IC chip, capacitor burned, a circuit problems, such as the general failure of the individual is not able to repair, it is recommended to repair or replace the relevant accessories or replace the power supply. In addition, the power supply quality problems (such as low voltage, abnormal fluctuation, etc.), may also cause this power off the fault phenomenon.
