Why does the computer keep restarting in the summer?

It's too hot and you open the lid of the case to let in some air.

There may be a problem with your heat dissipation.

Hello friends, your main problem lies in the lack of power of the power supply. I'll analyze the power consumption of the whole machine for you first:

X4 635 thermal design power consumption of 95 watts, motherboard, memory negligible, hard disk 9 watts, GTS250 full load power consumption of 150 watts, optical drive reading disk work 20 watts, total: 274 watts, 12V output at least the power required to ensure normal operation. Normally, considering the instability of the mains voltage when selecting the power supply, it is generally necessary to leave 15% redundancy, which means that this configuration needs at least a brand active power supply rated at 400 watts to ensure the stable operation of the whole machine.

The 12V output of the 300-watt rated power supply of Huntkey Cool King Diamond Edition is only 18A, that is, it can only provide 12x18A = 216W actual output capacity.

But the reason why it can run normally most of the time is because in the standby state or not in the state of full load, the actual power consumption of the whole machine cannot reach the nominal rated power consumption calculated above. However, when the rated power consumption of the air conditioner is nearly 2 kilowatts, the voltage will be temporarily unstable, and the landlord can feel that the brightness of the lighting equipment will dim when the air conditioner is activated. Then in the case that the power output capacity itself is insufficient, coupled with the instability of the voltage, it leads to a restart.

To solve this problem well, one is to change to an active brand power supply that is rated at least 400 watts or more, and the other is to consider upgrading the HD7750 with a full load power consumption of only 75 watts, and this graphics card does not need to supply power to the graphics card alone. However, the performance is much better than that of the GTS250, which consumes up to 150 watts.

I'm sure that if all the hardware is not faulty, this problem will be solved after upgrading the power supply.

This is obviously your console's power supply is not off. The power supply of the brand machine has been measured. It can ensure power supply at low voltage. Your host must have saved it yourself. The margin or quality of the power supply is not up to par. This is perfectly fine for restarting.

It is a voltage problem of the entire circuit, the voltage drops instantaneously when the air conditioner is turned on, and the power quality of your computer is not up to par. There are several solutions, one is to separate the computer and the air conditioner; the second is the replaced power supply; The third is to buy a UPS.

It is because the instantaneous power grid voltage fluctuation is too large when the air conditioner is turned on, which causes the computer power output to be unstable and causes the system to be unstable, so it automatically crashes and restarts.

Your power supply is a passive power supply, and the output power will fluctuate when the voltage is unstable. Although the target is rated at 300W, it is not as good as Huntkey multi-core R80 300, AC input: 90-264V is no problem, and sufficient power output can be guaranteed.

It is recommended to replace it with an active power supply. For example, Huntkey multi-core WD400 or the Huntkey multi-core R80 300 power supply with equal voltage.

Because the voltage in your home is unstable, the voltage of the air conditioner suddenly becomes weaker as soon as it is turned on, so the voltage cannot meet the minimum voltage requirements of the computer power supply, so it is restarted.

Can the air conditioner be related to the computer? You are not using an outlet -.Voltage instability caused by turning on the air conditioner?

If it's not a high temperature, then you use an outlet, and then the voltage is unstable, so it's better to find a new socket for the computer power supply, and don't use one with the air conditioner.

Oh, the reason is very simple, the instantaneous load change of the parallel circuit, coupled with the poor voltage regulation performance of your power supply, that's it, when the overall voltage load is too large, it will affect the most unstable electrical appliances. For example, if you try to turn on the light in the room (preferably an incandescent lamp) and turn on the air conditioner to see if the brightness of the bulb changes, try it first.

If you don't usually turn on the air conditioner, the computer can run normally, then it is not a matter of turning off the power supply at all, of course, you can disassemble another power supply that has not restarted the computer and replace it with your machine, and you will know that this is a problem of electromagnetic interference, go to the motherboard BIOS, find the spread spectrum and turn on this function to reduce the EMI generated by the pulse generator

In addition, check whether the power cord connector is loose, or try to change the power strip. Because I don't know where the host outside your air conditioner is, because if.

In the vicinity, when the main unit is turned on, the sound resonance will loosen the power plug that is not in good contact, causing the power supply to be transient.

The power supply load is too high, change to a 350W to 400W wide power supply.

The landlord did not make it clear, whether to turn on the air conditioner and restart instantly, or the air conditioner as long as the computer will restart uninterruptedly when it is turned on, if it is an instant restart, it means that it is not a problem with the computer, but a power supply line, and it is not necessarily like the upstairs 2 said The power supply quality is not good, the power supply design is different, and the voltage broadband is also different, such as 110-250 or 200-250, if it is this kind of failure, it is very easy to solve, and the power supply for higher broadband is one, and UPS power supply can also be installed, If it's the second phenomenon,It's caused by high-frequency interference,Now inverter air conditioners often do this,I'm doing Hisense,Frequent customers reflect,As soon as the air conditioner in his house is turned on, the TV will automatically change the channel in the middle of the night and start automatically and so on, and a series of problems,This problem can be manually connected to the ground wire in the chassis and connected to the wall,But the actual effect is not very obvious,

Do you still need to think about it? Toes know that the air conditioner is turned on, which consumes a lot of electricity and pulls down the voltage.

In the summer, the voltage of the power grid itself is not high.

Second, your computer's power supply is not very good, and now many good power supplies are designed with a wide voltage, and the voltage of 160 volts can be used normally.

Many small brands of power supplies have high voltage requirements. In this way, this kind of problem is most common in the summer, and the solution is very simple, buy a UPS with stabilizer, and it will cost 200 yuan. Voltage stabilization and power-off protection (if you buy a 500 computer with an ordinary configuration, you can use it for more than 20 minutes when the power is off).

There is nothing wrong with the hardware.

The system doesn't work.

Generally, the computer has been used for a long time, accumulating some dust, and it is easy to cause a short circuit in the electrodes when the ambient humidity is high. Workaround steps:

1. Turn off the computer and unplug the power cord;

2. Use a hair dryer or soft brush to clean up the dust in the chassis;

3. Disassemble the CPU radiator and fan to clean up the dust, and install it back as it is;

4. Remove the graphics card from the slot, clean the prongs with more than 98% pure alcohol, and install it back as it is after it is dry. If there are other cards, use the same method;

5. Unplug the signal cable between the host and the display, dip a cotton ball in alcohol of more than 98% purity (carbon tetrachloride is also OK), scrub the pins, and clean up if the display end of the signal cable can also be unplugged;

6. Temporarily unplug unnecessary external devices from the host, such as cameras, microphones, and printers.

After the above is completed, connect the monitor signal cable, plug in the power cable, check whether the display power cable is loose, and turn on the power after completion, and you're done.

It is estimated that it is dewed, even if the humidity is large, it will not blur the screen, at most restart.

The temperature of the accessories inside the case is too high.

What should I do if the computer is infinitely researched? There will be some problems when the computer is used for a long time, and recently some users have pressed the boot button, and the computer has entered a state of infinite restart, and it has not been able to turn on. The situation of infinite restart of the computer is either the software world is scattered or there is a problem with the hardware, and there are generally software problems, so let's take a look at the solution to the infinite restart of the computer.

1. If the signal light will still light up and the screen will light up after the computer presses the power button, then the computer is likely to have a problem with the software, and there is no problem with the hardware.

2. The software problem that can make the computer keep restarting may be that the computer is infected with a virus, or the system file is corrupted, for the software problem, we can press the F8 key when booting, open the advanced options menu, and select "Last correct configuration".

There are generally the following reasons for this situation:

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the check mark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

This is because you have been hit by the storm No. 1 virus, the current anti-virus software can only kill his mother, but those 1kb folder shortcuts are not harmful to clean up, and if you don't fix the modified registry entries, after restarting into my computer, there will be a message that vbs cannot be found.

Check the hardware temperature to see if it's caused by the high temperature.

Usually the CPU temperature is too high or the CPU fan is broken.

The weather is too hot, causing the CPU to overheat and restart.

3 possible causes.

1. The computer temperature is too high.

2. The grid voltage is too low or unstable.

3. The power supply of the computer configuration is too poor.

The estimated true cause is the second item. And the low voltage is not something you can control, you can add a voltage regulator or change to a better computer power supply.

Suggestion: You can change to a computer power supply with a wide voltage, such as R80 300, R80 400, WD 400, and Sanzhi WD500 of Huntkey series power supply.

The voltage adaptation range is as low as 100V, which means that the power output can be guaranteed normally when the voltage is as low as 100V or more.

Which is your computer power supply is too inferior, change to a good brand.
