Computer power-on automatic power failure Solution

Computer power-on automatic power failure One:

The specific situation is like this: turn on the power switch, press the power-on button, the 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?

A: 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.

Power off failure may also be caused by the following reasons: First, the chassis power switch problems, such as reset spring failure, the second is the CPU overclocking, or CPU fan problems. Third, the optical drive and other accessories have short circuit fault.

Computer power-on automatic power failure Two:

Failure Analysis: The computer after the power-on 10 seconds after automatic shutdown. 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?

A: 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 Analysis: 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?

Temperature reduction is likely to cause some of our problems, we suggest that you or the computer chassis to open, the inside can plug things to be reseated to install, see if you can solve the problem

Under normal circumstances, the computer power-on automatic power off solution after the power-on of 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.

Power down failure can also occur for several reasons:

First, there are problems with the chassis power switch, such as reset spring failure.

Second, the CPU is overclocking, or CPU fan problems.

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