Automatic Computer Power Failure

"Computer power-off (shutdown) causes and solutions
There are various computer problems. Here we will introduce the causes and solutions for the automatic power failure of the computer.
First, we analyze the cause and then come up with a solution. The main causes include the following: Of course, the possible causes cannot be ruled out.
First:CPU temperature overheated
Currently, the CPU is developed with temperature protection. If the CPU reaches a certain temperature point, a command will be sent to force power-off on the computer. The automatic power-off temperature of various types of CPUs is different, and some of them are also related to the motherboard (we recommend that you refer to the normal temperature values of each CPU from the manufacturer ).

Cause: 1. Poor contact between the CPU fan and the CPU, and poor seat of the fixed fan,
Second:Power supply, power cord
The power supply is the front end of the entire computer. Any device must rely on it to operate normally. Therefore, the power supply cannot be vague.Power supply is weak, power supply is damaged.
Poor contact with the power cord will also lead to this, so there is no need to explain it in detail here.
Third:Motherboard, CPU, memory
There is a problem with the power supply circuit of the motherboard, some of which are incompatible with the CPU, or some defects occur in the use of the motherboard and CPU.
The memory is faulty, causing the wrong command to be sent to the CPU, causing the computer to shut down instantly.
The solution to the common causes is as follows:
First, the CPU temperature is overheated.
The reason for this problem is simple:CPU cooling is poor. CPU fan does not turn, CPU fan speed too slow, poor contact between CPU and fan (less silica gel ). Replace the CPU fan and add thermal Silica GelIs the solution for this reason.
Second, it is easy to solve the problem of power supply and power cord. Replace the corresponding item for testing.
Third: the motherboard, CPU, and memory are excluded from the above two items.Replacement MethodCheck the exclusion.
Combining the above causes and solutions is a common problem. However, difficult and Miscellaneous problems cannot be ruled out. "
