The computer has a sudden power outage, and the computer won t start after a sudden power outage

You can first check what the maximum temperature of your CPU is in the BIOS, and then estimate that the power is almost out (about 2 hours) and restart. Take a look at what the current temperature is, and if it almost reaches the upper limit temperature, you can consider the CPU temperature. And are you sure your power supply is available, enough power?

If there are no problems with the above, you can basically take it to repair, and these problems can not be solved by fiddling.

Memory, graphics card, and power supply!!

It's all possible! Try them one by one.

You try it in the smallest system, that is, only plug in the CPU memory graphics card and hard disk.

Everything else is unplugged! See if there's a problem! If it's OK! Try plugging in the others.

Such as CD-ROM, etc., so that you may find the problem!

Supplementary question: Then you try to change the hard disk data cable, then try to change the power supply, and try your own hard disk on someone else's machine! Good luck!!

If the system is ghost, it is possible that the system has a virus.

Otherwise, there is a problem with the motherboard, and it is recommended to take it to the place where the computer is repaired to test it.

The motherboard battery is dead, it is recommended to go and replace it with a new one.

Motherboard Issues... Changing to a motherboard will definitely do.

Memory and graphics card to test it out.

If it's okay, it's a power supply problem.

shanliang, don't talk nonsense, don't mislead people, this is by no means a battery problem. Maybe it's a capacitor or maybe it's a gold finger, it's hard to determine.

Could it be that the voltage is unstable!

Agree with speakersound!

When the computer starts, it needs to read the boot data from the hard disk, under normal circumstances, the hard disk is in a high-speed running state, and a sudden power failure will cause the hard disk to stop working, which is easy to cause hard disk scratches and head damage. And you said that you will be good on yourself after being idle for a while, just after the power is off, the hard disk runs at high speed, it will produce heat, when you start the computer at the time, the hard disk may not be able to recognize the data at this time, the temperature is high, and the operation is slow, which may cause it to fail to start,

Is there also a safe mode boot and so on?

You see if it's a memory module problem, loose or stuck nest and dust, and it may be broken!

Of course, the sudden power outage may be the system broken,,It is recommended to reinstall the ,,, should be able to 、、、 thank you for adopting!! 1

Computers are this thing.

It is necessary to turn the button on and off from the beginning.

Otherwise, the system will be paralyzed.

If it is serious, it is recommended that you install it.

It's really not possible to reinstall the system.,If you can't turn on the machine by any method.,It's a sudden shutdown.,Caused by disk damage.,One is to deduct the motherboard battery and put it down.,One is to put it on for a period of time to try it on the start.,Or can't you just repair it.。

BIOS battery discharge method: Discharge the CMOS memory through the jumper: pull out the jumper cap next to the CMOS battery, insert it into another pin for a few seconds, and then pull it back into its original position, or take out the CMOS battery, short circuit the positive and negative poles on the battery for a few seconds, and install the battery.

Several possibilities:

1. The hard disk has a bad sector due to a sudden power failure, and the key files are deleted here, and cannot be loaded 2. The key files of the system are lost.

3. It is not excluded that the motherboard or graphics card or memory is faulty.

Solution: Install the system from scratch, if it can't be installed, send it for repair.

This is because the system will read the files in the hard disk into the memory operation, and the files will disappear after the memory is powered off, so it may be due to your sudden power failure that causes the system files to be lost and the system is paralyzed, and the solution is to reinstall the system.

If your computer won't turn on after a sudden power outage, there are a number of possible reasons. To Min Mu under are some possible solutions:

A sudden power outage may cause damage or malfunction to the power supply. You can check if the power cord is plugged in and if the power supply is normal. If you determine that the power supply is not normal, you will need to replace the power supply or send the computer in for repair.

Bad hardware can also be the cause of your computer not turning on. Check for loose memory modules, graphics cards, hard drives, and other parts, as well as processors that may be overheating. Try plugging the part back in or cooling your PC in a well-ventilated environment.

After pressing the power button, press F8 or other corresponding keys to enter safe mode. If you are able to successfully enter safe mode, you may be able to perform actions such as system recovery or system repair to resume normal boot.

During the boot process, there may be missing or corrupted system boot files. You can try to use the system disc or USB flash drive to repair the problem, or reinstall the system to solve the problem.

If none of the above fails, you may need to seek professional technical support and consider taking your computer to a professional repair center or contacting the computer manufacturer's technical support team for further diagnosis and troubleshooting.

Possible causes of automatic power outages:

First, after automatic shutdown If it can be turned on normally, then this situation belongs to the self-protection function of the system.

When the computer is overloaded or encounters other conditions that damage the CPU or system, poisoning, CPU usage is often 100 and so on. In order to protect the CPU from damage, the system automatically loses power. The search wheel suggests optimizing the system.

Second, poor heat dissipation, which generally occurs when the CPU is overheated or the CPU is overloaded due to the long-term operation of the computer. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function. If this is the case, you need to clean the laptop fan, radiator.

Third, the external equipment causes Shixin to automatically power off, and removes the newly installed hardware equipment such as external cameras, printers, and upgraded memory.

Fourth, the notebook itself is faulty and needs to be specifically detected.
