The computer suddenly loses power from time to time, and I don t know what the fault is

Basically, these. Hardware aspects and configuration shadow failure:

1.Check whether the power socket and plug are plugged in tightly (many inexplicable shutdowns and reboots come like this) set the alarm temperature of the CPU, and when the temperature reaches this point, it will automatically shut down.

To solve the problem, go to the BIOS to increase the alarm temperature. The premise is: ensure the security of the CPU.

3.The current is unstable. Buy a flow regulator.

4.It's not good to fancy up inside the case. Look at the CPU fan, if it doesn't work, change it, it's not expensive.

5.Hardware compatible, no hassle. Take your classmates' memory and sound card to swap them in. Run the interrupted time to see which one is incompatible.

6.The power of the power supply is too low, add some money to buy a high power supply.

7.Power quality issues. Call a few buddies and see the boss's attitude. Dare to fool us, on the smash shop Problems caused by software:

1.Check the anti-virus software or system software, and remove it first. If there is a failure, change to other software.

2.Check the drivers and update the drivers. If it is a new driver, changing to an older version of the driver can also solve the problem.

3.Check if it is caused by a Trojan horse.

Solve the nirvana of soft failure: reinstall directly, unplug the network cable, and run a clean system for some time. If the problem persists, basically troubleshoot the software.

I've had this kind of problem, two possibilities:

1. The memory module is loose.

The temperature is too high.

The power supply is possible, and then there is the motherboard

It feels like a symptom of a lack of power.

I don't know how watt your power supply is rated depends on your configuration, at least 300W.

Put the case in a ventilated place or disassemble the case to keep the contents tight.

The power failure must be a hardware failure, it is estimated that it is a problem with the power supply, change the power supply and try it.

It should be that there is a problem with the power supply and the chassis, I don't know if you are equipped with a set of chassis and power supply when you build the machine, it is recommended that you check it first, if there is no fault contact problem, you can see if there is a problem with the motherboard.

You see if your fan is loose, you can reinstall the fan and try.

I have a friend who's like you, but the fan isn't pressing

The bug said more comprehensively, it is generally a problem of heat dissipation and power supply, and it is not excluded that the voltage is very unstable.

Guess it is caused by static electricity, which is relatively dry in spring and easy to cause static electricity. The normal boot state will leak out with the normal current. It may be because of a sudden power outage, and the power supply does not stop working properly.

As a result, some of the current is left inside the computer. You plug it back in. It's about the same as discharging.

The motherboard or line current is working fine. It's on.

The solution to the power off of the computer automatically.

Power outages can sometimes cause problems inside the power supply, and sometimes it is enough to press the power button once to discharge the power supply and then plug it back in after unplugging the power supply.

Take a look to see if your power supply comes with a power-off protector, there will usually be a recovery button behind the power supply, and you may have inadvertently pressed it.

1. Maybe the memory battery (electronics) of the motherboard in the chassis is not working.

2. There may also be static electricity.

Automatic shutdown is more likely to be a hardware problem, and the method of first soft and then hard is used to troubleshoot.

First of all, reinstall the system with the pure version of the system disk, all hardware drivers, all use the official website version, this configuration, has the best compatibility and stability.

If the reinstalled system still shuts down automatically, it may be a hardware issue.

First of all, clean the gold finger of all boards, especially the gold finger of the graphics card and memory, to see if you can solve the problem. If not, the possibility of hardware failure cannot be ruled out, and it is recommended to send it to a repair shop for testing and maintenance.

First of all, rule out the situation of poor contact, unplug the power cord and plug it back in, if it is not bad contact, it may be that the temperature of the computer hardware is too high, and the next Master Lu uses the computer with high intensity to monitor whether the temperature of each hardware is too high, mainly the CPU and the graphics card, the hardware temperature is too high and will also cause power failure. If not, it may be that there is a problem with the computer hardware itself, mainly the power supply and the motherboard, and other parts are also possible, and this can only be tested and repaired by yourself in the computer store.

Possible reasons are:

1.Power line failure. Such as internal problems of the power cord, poor interface contact, etc. You can replace the power cord and see.

2.The internal power supply line of the chassis is faulty. Check that the socket is in place and that there are no breaks.

3.Power failure. If there is a problem with the internal circuit of the chassis power supply, you can check whether the temperature is too high, short circuit, etc.

4.The temperature of hardware such as the CPU is too high. If the hardware temperature exceeds the set value, the system protection will automatically power off or restart.

5.The motherboard is damaged. The circuit board is broken, soldered, etc.

、I think it's your computer that doesn't have good contact, or check things better than other places。

It may be something that is not in good contact, try to change the line, and if it doesn't work, you have to go to overhaul.

It is possible to protect oneself and go to repair.
