The computer will automatically shut down after a while, and the light of the host is still on

The relationship between the power supply is not enough, because at the beginning, only the CPU, memory, hard disk and a small part of the hardware on the board are working, and the load is not large, the power supply power can be handled, and you can give the CPU fan enough power, but after booting up, you have to run some things, such as movies, games or something, so that your graphics card begins to officially work at a high load, and the sound card is also (especially the independent sound card), if you are connected to the Internet, then your network card will begin to calculate the uplink and downlink of the broadband, Due to your various operations, the CPU usage is getting higher and higher, and the hard disk is also frequently reading and writing data. At this time, it is very different from just turning on for about 10 minutes, the load of the power supply exceeds 5 times that of just turning on for about 10 minutes, due to the need to maintain the function of various hardware, the power supply of the CPU fan is not so important at this time, from slowing down to stopping, and then to the CPU temperature rising, the motherboard after 965 will generally collapse above the CPU temperature of 176 degrees, just like you.

It's definitely not a fan problem, because there is no fan that will keep spinning well and then slowly slowing down, and then the lubricant in the fan shaft is slowly heated and dissolved, and the faster it turns, it would be good to change to a more powerful power supply.

The computer shuts down automatically, why? How to solve it?

It should be a bad heat dissipation, open the case, clean up the dust on the CPU fan and power supply inside, if it doesn't work, you have to replace the CPU fan with a little more power, there are a lot of problems recently, all of them were used to be equipped with the machine, the fan power is small, in addition to the computer has been running for a long time, useless system garbage, more dust, running large online games, etc., the CPU occupies more, can not quickly dissipate heat, resulting in high CPU temperature, resulting in a protective shutdown of the computerOh.

Why does my computer turn off automatically when the lights are on? Is there any way to fix it.

Hello dear <>

The computer will automatically turn off when the lights are turned on and on, probably because the computer and the lights are in the same circuit. The lamp itself has problems such as short circuits, which leads to circuit overload trigger protection and causes the computer to shut down automatically. Workaround:

1.Check the circuit: If the computer and the lamp are in the same circuit of the same skin, it is recommended to check whether the circuit is normal, whether there are problems such as short circuits, and you can contact a professional electrician for maintenance.

2.Change power management settings: Turn on your computer's power management settings and turn off options such as "Enable fast startup" and "Enable power button" to prevent your computer from automatically hibernation or shutting down when ambient light changes.

3.Replace the fixture: If there is a problem with the fixture, it is advisable to replace the fixture or repair the fixture.

4.Replace the outlet: If the outlet is aged or damaged, it is recommended to replace the outlet.

Why does my computer turn off automatically when the lights are on? Is there any way to fix it.

The computer automatically shuts down when the lights are turned on or off, which is usually caused by the power supply voltage not being able to keep the lights stable. When the lights in a room change, there will be a brief change in the voltage in the power grid, and if the internal power components of the computer are unable to adapt to these voltage changes, the computer will automatically restart or shut down. To solve this problem, you can try the following:

1.Use a regulated power supply. Plugging your computer into a professional, regulated power supply that is not affected by external appliances such as room lighting can effectively fix problems caused by voltage instability.

2.Replace the internal power supply. If the power supply inside the computer is old or of poor quality, it will be more unable to cope with voltage fluctuations, and you can consider replacing a high-quality regulated power supply to improve this problem.

3.Disconnect other devices. If there are other devices connected to the circuit where the computer is located, the switching of these devices will also cause voltage changes, and connecting the computer to a dedicated circuit separately can reduce external interference.

4.Lower the time kernel voltage setting. In the computer BIOS, ACPI options can be set to allow for a wider range of voltage variations, such as setting the "ACPI HPET Timer" to 128 or 256 US, which can reduce the impact of small voltage changes on the system.

5.Update the BIOS and drivers. If the version of the BIOS and power management driver is older and less adaptable to voltage fluctuations, it is possible to improve the computer's ability to handle such events.

6.Reset the BIOS. If the problem persists after the above settings, you can try clearing the BIOS and restoring all settings to the default values, and then manually setting the system parameters according to the computer configuration, which may refresh some of the system defects that are causing this problem.

7.Check the motherboard capacitance. If the capacitance associated with the power supply circuitry on the motherboard is severely deteriorating, it will also cause the computer to be more sensitive to power changes and need to be repaired or replaced by the motherboard.

Hopefully, the above methods can help fix the problem that your computer automatically shuts down when the light is turned on and off. Since this fault may be related to the hardware circuit of the computer, if the problem is not solved after trying various software settings, a technician needs to test the internal circuit of the computer to rule out the possibility of hardware failure.

The analysis of your computer situation is as follows;

1.From a professional point of view, your computer motherboard is leaking power after shutting down, and all the lights will be turned on and off all the time.

2.Then why can't the light turn on? The reason is that the boot timing is wrong due to leakage, so it can not be turned on, 3The power supply must be cut off, it is the system power reset, and the light is off before it can be turned on.

4.I reported the maintenance and said that it was **** broken, I don't think he lied to you, but as for asking for 400 yuan, it is indeed too much, 5Generally speaking, it will be a small pipe that is broken, resulting in electricity leakage.

It's good to replace, in fact, like you, the computer has been bought for several years, you can not repair it, every time you shut down the power supply, use it and turn it on again, it doesn't affect the use, you can also change a computer that has been bought for several years.

It's true that I hacked you, and decided that I didn't need so much money. Many faults are related to dust, clean up the dust, and the power management settings of the motherboard should not be a big problem.

Why do you want so much money They don't know if it's your computer problem or the plug-in board problem, find an acquaintance to take a look, and if it doesn't work, they will check how to disassemble the host and then try to repair it themselves.

The maintenance cost of brand machines has always been very expensive. It is recommended that you take it out in the future and ask first before considering which family to repair.

It's too dark.,A few years ago, the computer is now about 200 yuan to buy a new motherboard.,Then it's going to be used.,Is someone into the BIOS setting up something.。

Check it up. Or the battery of the motherboard CMOS is dead, change to a 3V lithium battery for 3 yuan, reset the BIOS, and it's OK.

Usually the motherboard is faulty or the power supply itself is faulty.

This situation is usually due to a faulty motherboard (damage, short circuit, etc.) that causes the ATX power supply to protect itself and not work, or the power supply itself is faulty and does not work.

Recommendation: In this case, it is best to replace and test with a normal power supply.

A: Reason.

Since the computer motherboard can be remotely started and the keyboard and mouse can be turned on when the computer is shut down, most ATX motherboards, after the complete shutdown, the computer power supply will still provide 5V power supply for the motherboard, which is also the reason why the indicator lights and decorative lights on the mouse and keyboard will still light up after the computer is shut down.

B: Workaround.

1. Boot up and press Delete to enter the BIOS and select Power Management Setup.

2. ERP support sets this function to enable to save and exit by pressing F10.

Hello, the weather is hot, and the main cause of automatic shutdown should be the temperature of the CPU or discrete graphics card! 1.: Poor heat dissipation.

Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal. 2.: Memory reasons.

When the memory and the motherboard socket contact is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard, or you can change the socket to see if the downstream is not 3: Check whether the CPU is overheated, whether the CPU fan holder is stable, if it is broken or unstable, the CPU fan cannot be pressed, the CPU fan heat dissipation capacity is insufficient, the CPU temperature is too high, the automatic protection function of the motherboard will automatically shut down, and it is caused by the loose screws of the CPU fan! 4:

It may be caused by the unstable voltage of the main engine, and you can replace it with a high-power power supply. It may be that there is too much dust on the fan, which causes the automatic shutdown, and it is normal to clean up the dust! IT elite organization 乄 ip worm sincerely serve you If the problem is solved, please give a"Positive reviews"！

Thank you for your support

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to use 360 Antivirus 360 Security Guard to repair it in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

Dear,Change the socket just to let the main power off.,If you want to turn off the power without pulling out the socket, you have to go to the power button setting and not select the sleep mode.。 You can change the power button setting to sleep mode in the computer's power options (advanced power management).

Hello! After turning on the computer, the power indicator on the host panel turns off as soon as it is turned on, indicating that there is a problem with the power supply part of the computer, generally:

1. Host power supply.

1. The dissipation power is not strong;

Generally, the characteristics of the power regulator tube deteriorate, or the filter capacitor is seriously leakage;

2. The characteristics of the voltage stabilization circuit deteriorate, resulting in the output voltage being high and low, and the automatic protection circuit is started (self-protection);

Second, the main board. 1. The voltage adjustment tube on the motherboard is soft breakdown, or the filter capacitor is seriously leakage;

2. The characteristics of the main control chip of the graphics card are deteriorated, or the filter capacitor is seriously leaked;

3. The power control chip of the hard disk is damaged, resulting in a serious low power supply voltage of +5V and +12V;

From the point of view of the probability of failure, the first item has the highest chance, and the second item is second (in order);

Therefore, it is recommended that the landlord first borrow a reliable high-power host power supply to try it.

1. The hardware inside is loose, if you have the ability to do it, take it apart and pull out the CPU, graphics card, and memory and plug it back in, mainly memory.

2. If you don't have the ability to do it, find someone to fix it.

3. If it is not the above reasons, it may be that the hardware is damaged.
