Why does the computer automatically power off after running for a period of time, and then restart a

The computer may have been set up in this regard, so it will automatically power off after running for a period of time, and then automatically restart, which is related to the computer's settings.

It should be a system bug, it is recommended that you reinstall the system yourself first, if it doesn't work, you can only send it for repair, it's still difficult to find the problem yourself!

In this case, of course, it is a setting problem, he may be set to a certain time to stop the machine, will shut down and then automatically turn on.

What's going on with the computer turning on and automatically powering off?

When we press the power switch, the power supply starts to supply power to the motherboard and other devices, and when the voltage is not stable, the control chipset on the motherboard will send and maintain a reset signal to the CPU, so that the CPU will automatically return to the initial state.

Next, let's take a look at how to solve the problem of automatic power off when the computer is turned on.

The computer is automatically powered off when it is turned on

The specific situation is like this: turn on the power switch, press the power button to turn on, the fan turns, the machine has movement, and the power is off after a while, the fan does not move, the indicator light does not light up, and then press the power button is useless. Turn on the power supply, and after a while, restart the power and repeat the above situation.

And after I power the hard drive, I can turn on the machine until it detects that the hard disk does not have this step. Sort out the optical drive power supply again, and after a period of nonsense, it can be turned on and work normally for a day (no longer without turning off). Excuse me, what's going on, I don't want to do it every day, how can I fix this?

Answer: This situation of automatic power off after power on is likely to be due to a failure of the power supply or motherboard. The causes of failure are varied, such as IC chips.

Capacitors burned out, a circuit has a problem, etc., generally speaking, such a fault is not possible for individuals to repair, it is recommended to send it for repair or replace related accessories, it is recommended to try to replace the power supply first. In addition, the power supply quality problems of the mains (such as low voltage, abnormal fluctuations, etc.) may also cause this fault phenomenon of power-off and power-off. Power-off failures may also be caused by the following reasons:

One is that there is a problem with the power switch of the case, such as a failure of the return spring, and the other is that the CPU has been overclocked, or there is a problem with the CPU fan. Third, there are short-circuit faults in optical drives, hard disks, and other components.

The computer is automatically powered off when it is turned on, and fault two:

Fault analysis: The computer will automatically shut down after 10 seconds after turning it on. The CPU and so on have been cleaned up, and the power supply should be fine, because it can be turned on normally when using the hardware test of another computer before, what is the situation?

A: It could be the CPU temperature.

The computer is automatically powered off when it is turned on, and the fault is three

Fault analysis: My computer has been turned on and off power recently, and I don't know what's going on, it used to be fine, but this situation often occurs when the temperature drops recently, what's going on?

The temperature drop may cause some problems that we can't figure out, so it is recommended that you open the computer case, unplug and install everything that can be plugged in and out of it, and see if you can solve the problem later.

Under normal circumstances, the solution of automatic power off when the computer is turned on, and the situation of automatic power off after booting is likely to be a failure of the power supply or motherboard. The causes of the failure are varied, such as IC chips, capacitors burned out, problems with a certain circuit, etc., generally speaking, such a fault is not possible to repair the individual, it is recommended to send it for repair or replace the relevant accessories, it is recommended to try to replace the power supply first. In addition, the power supply quality problems of the mains (such as low voltage, abnormal fluctuations, etc.) may also cause this fault phenomenon of power-off and power-off.

The computer won't turn on, and it restarts a few seconds after booting, you can troubleshoot it in the following ways.

The first one, which is the common premise of power failure, is to remove the memory module, clean the memory gold finger, and fault different memory slots through the memory, and eliminate the memory slots if possible, but also clean up the memory slots to prevent the restart problems caused by poor contact of the memory slots and memory.

Second, under the premise of power failure, if you install a discrete graphics card, check whether the discrete graphics card is connected to the independent power supply normally?

Third, try to enter the USB flash drive PE system with the help of the USB flash drive PE system, if it can enter normally, then you can eliminate the hardware fault and lock the problem in the system problem.

If the power is suddenly cut off, you can first see if the stability of the CPU is normal. If it is not normal, it means that there is a problem with the CPU fan, which causes the computer to shut down automatically.

You need to check whether you have entered the system after restarting, if you can enter the system normally, it means that it is a power supply problem, if you can't enter the system after changing a power supply test, you need to detect whether there is a problem with the system.

There is a virus in the computer, and it is recommended that you clean the virus for him, and then redo the system for him, and this situation has happened to the computer before.

The computer suddenly loses power when it starts, and then automatically restarts and loses power and keeps looping, because the computer power supply is improperly connected or the system itself is faulty, it is best to find a professional to check and repair, so that the computer can be used more smoothly.

The workarounds are as follows:1You can plug and unplug the memory stick, and you can use an eraser for the gold finger of the memory stick, and you can wipe the gold finger.

2.If you have a problem with the hard disk, replace it with another hard disk and see if it can go in normally.

3.See if there are any wires or anything that are not connected, and just recreate them.

Hello friends, judging from your statement, it is very likely that there is a problem with your restart switch, you can disconnect the plug-in cable of the restart switch, and then turn it on normally to try it, if the problem is solved, it means that there is a problem with your switch. Replace one in time and you're good to go.

Initially judge that there is a problem with the power supply, try to replace the power socket, in addition, do not use it like this, it may cause damage to the hard disk due to more times.

In such a situation, it is generally necessary to check the power supply. This is caused by the fact that the power supply cannot provide a stable current to the computer. It is recommended to replace the power supply first, or add a voltage regulator.

This means that your computer's boot system is malfunctioning and you need to redo the system. Just get it to the computer repair department and start the system.

The computer will suddenly lose power after being turned on, which is a problem that occurs in the computer itself. It's okay to restart now, and if you keep looping, it will also cause this effect.

In this case, there should be a problem with the computer's power button, you can turn on the computer's power button and pull it upward. This phenomenon is repeated forced to turn on and off.

If the computer fails and you can't solve it yourself, it is recommended to find a special maintenance person to repair it, which will also save you time.

The computer suddenly loses power after a while, and then automatically restarts, and the power is cut off, and it keeps looping, it seems that there is a problem with this computer, and he may need to be plugged in all the time to run, if it is not plugged in, there is no way to run.

In this case, it means that your computer is not in good contact and the circuit is short-circuited, so you must repair it to achieve the desired effect.

In such a situation, the computer may be a problem with the system, so you should find a professional in this area to repair it.

It may be that the voltage is too low and the computer will automatically restart, or it may be caused by computer poisoning.

The computer suddenly loses power after being turned on for a while, and it automatically restarts again, and the cycle keeps repeating, which should be that the host has been broken.

Hardware failure. Power supply, motherboard, CPU are all possible. Professional investigation is required.

The computer will automatically power off after a while after starting, and the reasons are as follows:

1. The power supply is unstable, the voltage is not enough or it is broken.

2. Poor contact of the motherboard power supply.

3. The CPU conducts heat poorly, overheats, the CPU fan does not rotate or the speed is slow or even broken.

Tools: eraser, memory stick, screwdriver.

1. Use a screwdriver to remove the screws from the main unit.

2. Open the side cover of the case to see the approximate location of the memory module, which is usually near the CPU fan.

3. Gently push the buckle on one side of the memory module outward, and push the buckle on the other side away, and you can remove the memory module after both sides are opened.

4. Wipe the gold finger part with an eraser to remove the memory stick, the poor contact is mainly caused by dust and gold finger oxidation on it, do not touch it with your hands after wiping, wipe the eraser scraps on it with a cotton cloth, and then install it back on the host.
