The computer often crashes suddenly, and it can t be warm started after the crash, and the power can

The power grid voltage may rise for a short time, so that the power box in the computer enters the protection state, and the power supply must be dialed to exhaust the remaining power before exiting the protection.

There are many reasons, and the power supply is the most suspicious, so try to change the power supply first. There are also many possibilities for motherboards, so it is recommended to try the substitution method.

Reason: The case power supply is generally very hot, and the first reason for sudden shutdown may be a sudden power failure, or because the working temperature is too high, the motherboard loses power by itself. Clean up the main unit, and then plug in all the cables and check it.

Turn on the power again, check whether the power supply fan is rotating, whether the cup fan is rotating, and if it doesn't rotate, the problem is there. If both are normal, and the hard disk light is also normal, but there are no cracks and clumps of booting, it may be because the motherboard is too high in working temperature and the heat dissipation equipment is burned out. (The weather is very hot in summer, and its burden is greater, so if you turn on the computer for a long time, you don't mind opening the main chassis, and the heat will be dissipated a little faster.)

> the second reason, the hardware runs for a long time, plus dust, there may be poor contact, remove the memory module and wipe the gold finger, the graphics card is also, remove the hard disk buried cable, and then plug it in. If there is still no sign of luck that can start, either the motherboard is broken, or the cup is damaged due to high temperature. The cup can adjust the working temperature in the motherboard settings, and it will generally not burn out, so it is better to ask a professional to test the motherboard.

If all the hardware can be powered on well, then your system will lose some files due to a sudden power failure, and you can restore the system or redo it.

This answer applies to most computer models such as the Dell G15.

I'll just say a few situations I've encountered:1Subtract the battery to try. 2. Try to change the memory module card slot, sometimes it will be short-circuited and burned. 3. Clean up the dust. Most likely, the first two cases.

If the power is suddenly cut off, turn off the power strip, unplug the power cord, and turn the power on again. Generally, it is mostly a power supply problem.

Your machine may be used for too long, and there may be some problems with some accessories in the computer, so it is recommended that you repair it

First, it is possible that your power plug is loose.

The second may be that there is a problem with your power interface, third, it may be that your motherboard power cord is loose, and fourth, this is the point, in the future, when you encounter this situation, you unplug the memory and graphics card, wipe its gold finger with an eraser, and then install it back, ok The problem is solved. Remember to dust your computer regularly. Answer seriously. If it helps you, remember to give points.

You take the battery off the motherboard and discharge it, and it's OK.

Check the motherboard's manual and try to discharge the BIOS.

Temporary disorders.

Maybe it's the power cord that is in poor contact Try changing the wire.

You're in exactly the same situation as me, but I'm a new computer. I hope you can reply when you see it, at the moment I have not solved this problem.

1. Reinstall the system; 2. Check whether the hard disk has bad sectors, if there is, you need to use software to repair the bad sectors first, if it can't be repaired, you need to send it to the after-sales service for repair or replacement; 3. Enter the safe mode for anti-virus, if the virus cannot be killed, it is recommended to reinstall the system.

Therefore, to eliminate them one by one, start with the software, that is, reinstall the system to see if it can be solved, and if it can be solved, it will be done. If it can't be solved, it depends on the hardware, such as hard disk failure, motherboard failure, etc.

There are several possibilities.

One, the CPU fan does not turn.

When the temperature reaches a certain level, the motherboard automatically loses power.

Automatic protection, when you do not unplug the power, click the power button.

Definitely won't let you turn it on, just unplug the power and plug it in, but the temperature is high, and it's still a problem.

Very much with the probable) two. Is the host regaining the tide?

That hair dryer blows.

It's best to put it outside.

Dry for two days. It works better.

Three. It is not caused by ambient static electricity.

If you're sure you'll be fine.

Then let's test it by a special department.

Maybe there's something wrong with the motherboard.

It could be a heat dissipation problem with your computer or that your computer is poisoned. If your computer is dead for a long time, touch the aluminum sheet on the CPU with your hand to see if it is overheating when the power is off, and replace it immediately. If the problem persists after replacement, please replace the memory, hard disk, and graphics card in turn to see if it can be solved.

Maybe it's the protection mode of the system hard drive

Shut down when the data is not finished

Crash caused by a collision between the shutdown program and the hard disk protection mode If your motherboard has this function, it is recommended to set it in the BIOS

1. When booting up, you can press the F8 key to enter the safe mode and uninstall the previous software, which can generally be solved. 2. If you still want to install the software, please read the system requirements of this software before installation. 3. If the problem has not been solved, please consider reinstalling the system.

There are several possibilities for this kind of problem:

1. Detect the heat dissipation device to see if there is a fault.

Second, try to remove one of the dual memory first, if there is memory incompatibility, it will usually lead to this situation.

3. Use the latest version of virus software to conduct a comprehensive investigation and killing (it is recommended to use the latest version of "Kaspersky").

4. If all of the above are normal, please repair the system or reinstall the system. This can also happen if a related file in the system is corrupted.

There are actually many reasons why the computer suddenly crashes, so let's analyze them one by one. One of the simplest and most common types of sudden computer crashes is due to the sudden loss of the computer's power supply, resulting in a sudden computer crash. This reason is very common, and it is very easy to solve, we just need to reconnect the power to make the computer work normally.

It is also possible that the computer suddenly crashes because the computer itself is running a large number of programs in a short period of time. Because the memory and response speed of the computer are limited, when a large number of programs are opened at the same time, it will cause the computer itself to crash, and the computer will automatically shut down the computer for protection in order to ensure the safety of its internal construction programs, which in our opinion is the phenomenon of sudden crash. In this case, just like our mobile phone crashes, we don't have to worry too much, we just need to use the cleaning software on the computer to clean up the background running programs in time, delete the garbage, and then we restart the computer, and the computer will work normally again.

There is also a possibility that we have carried out improper operations when using the computer. Due to the existence of many Trojan viruses, when we enter the improper ** illegal operation, these special Trojan viruses will immediately invade our computer, resulting in abnormal shutdown activities of our computer, and the phenomenon of sudden computer crash. If the computer suddenly crashes due to this reason, then we need to be very careful, and our computer information is likely to leak through this crash.

Therefore, when we browse improper ** and carry out illegal operations, the computer suddenly crashes, then we had better find professional computer security personnel to encrypt our computer data at the first time to prevent the leakage of computer information.

What type of graphics card, if there is a core display, try to unplug the independent display, plug the display cable into the motherboard, and use the core display to see if it can be turned on.

It is recommended to send it to the place where the computer is repaired.

Boot press f8 do not move to the advanced option appears in the let go, select "the latest correct configuration" enter to repair, not yet restore the system. The following describes how to diagnose the failure to boot the operating system. First, check to see if the computer has started booting up the operating system when you turn it on.

If the operating system freezes, blue-screens, or automatically restarts when the operating system is booted, the partition table and master boot record of the hard disk are normal, and the fault causes such as the corruption of the hard disk partition table, the corruption of the master boot record of the hard disk, and the loss of the hard disk partition end flag are ruled out. The following method is then used to make a diagnosis. Step 1:

If it doesn't, it may be infected with a virus, system files are missing, the operating system is corrupted, the hard disk has bad sectors, the hardware device has conflicts, or the hardware has hardware.
