Why doesn t my machine turn on intermittently?

I'll give you a suggestion to solve the problem, 1, your machine is an assembly machine or a brand machine, 2 if it is a brand machine, you have seen the quality assurance time, if not, or contact the seller, if it is over or assemble a compatible machine, first see if your machine is turned on to alarm, if the alarm is a few long paragraphs, and then open your machine, (is not very dirty, if it has not been cleaned, first take a hair dryer to clean it, if you will not find professionals or computer enthusiasts to help) One of my customers is also the same problem as yours, the following is my solution, take down the memory first, wipe the gold finger with an eraser, (that is, the glittering part inserted in the slot) wipe both sides, and then try, if the problem has not been solved, it is a problem with the power supply of your host, so you have to find a special hardware supplier to solve it Find him to change one.

I analyze that there may be two reasons, one is that your computer motherboard may be a little damp, and the other is that the computer motherboard has a power-off protection device, which cannot be switched on and off frequently, and the power-off interval is too short, and the power-off protection of the motherboard is started, so it will be restarted later.

I'm good at this problem, because my computer is like this, but I've found the reason, it's the power battery, you can change the power battery, or take out the power battery and pinch it, and that's it. By the way, is the time on your computer accurate? If it's often inaccurate, it's guaranteed to be a problem with the power battery!

Judging from the illustrated situation, it cannot be damp.

This kind of problem can be a lot of problems and nerve-wracking to analyze.

1. Poor contact between each board. It is related to temperature deformation.

2. A non-standard chassis will deform the motherboard. Cause the traces on the motherboard to break.

3. Motherboard aging, such as motherboard capacitor leakage, etc.

This is most likely due to the high temperature of the weather. If you can turn on normally after 15 to 30 minutes of shutdown, it should be. In this case, you can see if there is any way to cool down.

I think it's likely that the power supply is not enough, and if the power is not enough, the motherboard will automatically shut down, so I suggest that you better change to a power supply with a higher power.

Is there something wrong with your power supply, or your motherboard battery is dead.

Reasons and solutions for the computer to sometimes turn on and sometimes not to boot: 1. The memory card cannot be read by the host normally. Turn off the computer, turn off the power, wait a few minutes, and turn the console on.

Pull the memory card out of the card slot, wipe the area with the gold finger with an eraser, and then wipe the dust from the card slot with a fine cotton swab. Wipe it clean and plug the memory card back in, then turn on the computer and see if there is still a situation that won't boot.

2. Replace the power supply and power cord in the host. If the power supply is damaged or soldered, it will also cause the computer to fail to power and turn on sometimes. In addition, if the power cord is not in good contact or is not tightly connected to the host socket, it will also cause the computer to not boot normally.

3. The boot button of the computer is not in good contact. When too much dust accumulates, the boot button will be sticky and cannot be used normally, so you can replace the boot button.

Friend, solve this problem and try it with elimination:

1. Power supply: Open the chassis, unplug the power pin jack, turn on the power supply, short connect the green and black wires, if the power supply can work normally, the problem of the power supply can be ruled out, if it does not work normally, replace the power supply.

2. CPU: Open the case, use your hand to sense the CPU temperature, if the temperature is too high, judge whether the CPU heat dissipation is not good, check whether the fan is normal, or change a fan, clean up the CPU and fan dust.

3. Memory: Whether the memory is used in two roots, in order to eliminate incompatibility problems, plug one first.

4. Motherboard: Intuitively judge whether there are any damaged electronic components on the motherboard, if necessary; Clean up the dust from the motherboard, etc.
