The voltage is unstable, the computer will crash when the voltage is low, and it will die ten times

It is recommended to add UPS and stabilized power supply.

Go buy a voltage regulator for your computer.

The use of electrical appliances requires a stable voltage environment. The same is true for computers, if the voltage is unstable, it will cause great damage to the computer. Low voltage will cause the computer to shut down automatically, and then every time it is turned on, it will self-test the hard disk, which will cause great damage to the hard disk; The instantaneous current passing and cutting has a certain impact on the CPU, the north-south bridge chipset and the motherboard, and even burns out.

If it is indeed a crash caused by low voltage, the landlord needs to buy an ultra-low voltage regulator to ensure the normal use of the computer.

You can consider purchasing a regulated power supply.

Then turn off the computer quickly, find a computer city near your home, and ask the master to repair it, or replace the power supply. I recommend that you clean up the dust first.

Unstable voltage can cause the computer to restart suddenly or shut down with a black screen.

Hazards of unstable voltage: Hard drives are most likely to be damaged, followed by the power supply and motherboard.

Extended reading: If the market voltage is unstable, then the good) signal received by the CPU will be unstable, and only when the CPU receives a continuous and stable PG signal, the computer can work normally. When the PG signal is intermittent, the computer restarts. The harm caused by this is the possibility of losing data at work, as well as causing damage to the hard disk, which may seriously affect the service life of the hard disk.

It is normal for the mains voltage to fluctuate between 180V and 240V and will not damage the computer.

If you are using a laptop (with battery), the impact of voltage instability on the laptop is relatively small.

If the voltage fluctuation range is too large, any computer will be damaged.

I'll answer you this question, I have had such an experience before, so I can best understand your suffering, there is a UPS or a power outage because the voltage is fierce and the low UPS can not be stabilized, if the voltage is low UPS just bought when it can be stable for a while, I 2 UPS used more than a year to hang up, I used to be the light suddenly dimmed, a few minutes at the peak, I suggest you still find the power supply bureau, After 2 years of hard work, the power supply bureau finally gave us a separate transformer, the property and the power supply bureau will push around, do not do things, I suggest you complain to them more, I know the complaint method of the power supply bureau, the property is not very clear, you check it yourself, the following is the complaint method of the power supply bureau.

You can first go to the power company and explain the reason to them, the power company has reflected that it is not good, you can call 95598 This is the city electricity complaint**, if your computer hardware hardware is caused by the loss of voltage, you can go to the local power company to find them to repair or compensate, the power company has to buy insurance in the insurance company, and the insurance is in terms of maintenance and compensation.

For specific details, the landlord can call 95598 to inquire, good luck, and I hope you will win the holy war like me.

The voltage there is too low, and even the voltage regulator can't be supplied at the bottom, so if you want to completely solve the problem, you can only collectively go to the power supply to apply for transformer capacity increase!!

The voltage is unstable, your computer must be powered off, you buy that voltage regulator is useless, suddenly the voltage drops to the end, your voltage regulator is still working

The other is CPU overheating

1.Test whether the output voltage of the refrigerator regulator is 220V, and the output voltage of 12V and 5V is normal.

3.Focus on checking each plug for good contact.

Try it without UPS! A high-precision servo voltage regulator should be used on the computer, but an ordinary refrigerator voltage regulator is not good.

Dialectic: 1. If you use a low mains voltage, it will not cause the computer to crash, but will automatically shut down. That is to add a UPS regulated power supply, but it cannot solve the fundamental problem, and can only ensure that the low voltage maintains a stable power supply in a short time.

2. The voltage of the computer power box is low, and the output voltage is not enough, which causes the hard disk speed to be insufficient, resulting in the computer crashing, so it is necessary to replace the power supply and replace one at a professional computer maintenance point.

Add a stabilized power supply, about 300 yuan.

Is the computer voltage low, or the 220-volt power supply at home low?
