Why does my computer crash when it thunders?

Generally speaking, the computer burned down due to lightning is very small, if you accidentally get hit, it is mostly because the instantaneous voltage is too large, and the power supply part of the computer is burned out. If it's a laptop, then it's the motherboard's power module or power adapter. Below, let's learn about the relevant knowledge together!

When thunder, lightning will be transmitted to the terminal through some communication lines or power lines, if the voltage is too high, the voltage regulator is not used. You can't turn on the computer when there is thunder, it is to prevent lightning strikes, and everyone knows this. In severe cases, it will burn the network card, especially the ADSL cat, and even the computer host and monitor.

Therefore, when thunder, not only can you not play with the computer, but you also have to unplug the network cable.

How can you tell if your computer has been struck by lightning?

Although the probability of a computer being struck by lightning is very low, if it does happen, we can use the following points to determine it. The first is that it can't be turned on, and the second is the problem on the motherboard. If the lightning voltage is too high, the motherboard damaged by the lightning will be unable to withstand the motherboard original and even the PCB breakdown, burnout, the motherboard north and south bridge and other IC chips are completely scrapped, similar to such a motherboard, there is no longer any maintenance value, can only be replaced.

What happens when you thunder and charge your phone.

Although the amount of electricity contained in lightning is very large, there are lightning rods installed in many places, so it is not very easy to charge mobile phones. But sometimes the weather is particularly bad, that is to say, the lightning is particularly bright, but also very urgent, and accompanied by strong winds and heavy rain, such weather will generally not take long to pass, in this world it is best not to use mobile phones or charge mobile phones.

Under normal circumstances, if there is no circuit system in the home and no grounding capacity system, it will generally be knocked out;

But today's electricians are able to minimize this;

Worst Result: Burn them all. General result: the power supply of the host burns out, and it is OK to change the power supply at this timeThe display burns out;

But the current display, the lightning protection effect is good, coupled with the special design of the power supply, the probability is very small The power plug of the modem is burned out, change or buy one;

Under normal circumstances, it will not come down the network line, and if this is the case, China Telecom and other ** providers are estimated to not survive for long.

Under normal circumstances, thunder will generally be knocked out if you have no electrical system and no grounding system in your home, but today's electricians can minimize this situation. Worst Result: Burn them all.

General result: the power supply of the host burns out, and it is OK to change the power supply at this timeThe display burns out, but the current monitor, the lightning protection effect is good, plus the special design of the power supply, the chance is very small The power plug of the modem is burned out, change or buy one.

Under normal circumstances, tiredness will not come down the network line, if this is the case, China Telecom and other ** companies are estimated to not survive for long.

Thunder will not split the computer, the lightning cracks the computer is along the network line, the network cable must be unplugged when the thunder strikes, don't think that everything will be fine when the machine is shut down, even if the machine is shut down, the thunder will also come down the network line, and the cat and the network card will be broken.

Basically not, this situation rarely happens, people indoors, the house itself constitutes a protective cage, and now the house generally has a lightning bridge dust bucket, lightning can not enter the room.

If there is no lightning rod, you should turn off the power supply in your home, because even if lightning does not hit the house, it may damage the electrical appliances in your home. Lightning strikes next to your home, the changing lightning will produce a changing magnetic field, and the changing magnetic field will produce an electric current, which is an electromagnetic induction phenomenon, which can make the metal wires in the home produce additional current, and the current overload will instantly burn the electrical appliances.

A house with a lightning rod may also be affected by lightning, the role of the lightning rod is to protect the building, and a large number of induced charges are gathered at the top of it, which can first combine with lightning and lightning to quickly channel lightning into the ground to ensure the safety of the building. However, the home power grid is externally powered, and if lightning strikes the external power grid, it can generate tens of thousands of volts of voltage in an instant, and directly burn the home appliances through the line.

Pay attention to the following points in thunder and lightning weather: sensitive grinding

1. Don't stand under a light bulb indoors. When lightning strikes the light bulb line, it will increase the energy of electricity in an instant, and the bulb will be overloaded, releasing ultra-high light energy and heat energy in an instant, thus causing burns to the human body.

2. Don't pick up **. Try not to hit ** when thunder and lightning, or use a computer to surf the Internet, you should unplug the ** line and computer network cable, so as not to cause lightning strikes in the corresponding line, and do not use your mobile phone to receive ** when thundering, which will not only cause damage to the mobile phone but also increase the risk of lightning strikes.

3. Outdoor exercise is not suitable. Do not exercise outdoors during thunderstorms, if you encounter thunderstorms during outdoor sports, you should find a suitable shelter from the rain as soon as possible to avoid lightning strikes, and do not open the umbrella when outdoors to avoid the formation of tip discharge and lightning strikes.

When thunder and lightning hit, the sedan car was shining.

The space will be damp.

Generally cloudy.

Then of course there is conductive water vapor in the air.

It is not visible to the naked eye.

You don't have a lightning rod in your house. If there is lightning protection, it is like a needle.

It can be connected to a ground wire to direct static electricity in the air to the ground and then release it.

If there is no lightning rod.

It will be directly powered to an external power source.

Electrical equipment that is linked to the power supply and in use will be disturbed.

At worst, there is damage.

Thunder and lightning seem to be far away.

But the impact is close at hand.

If you're not careful, you're vulnerable to injury.

It should be said that the electromagnetic field generated by lightning can affect the amount of current in the wires, which can damage your computer, and if you are on the computer, it may also endanger your life.

Not only computers, but also electrical appliances powered by AC circuits are best not to be used during thunderstorms.

However, many new buildings now do a good job of circuit insurance, and there may not be the problem of excessive current, but it is best to pay attention.

Lightning has a strong destructive effect on electronic products, and the high voltage of lightning can cause damage to all electronic products in the system if the key is struck with the power system's tremor stockings.

My desktop computer was almost broken because of the lightning, and the monitor was burned out that day.

It is best to turn off the computer when there is thunder, and all electrical appliances that need to use electricity When the voltage is unstable when the lightning strikes, it will burn out if you are careful.

Hello, weather like thunder is because lightning strikes your network cable will burn the network card, hit the wire will burn the power supply, and jujube sheng may burn the CPU, so the computer will be broken, because the voltage is too high!

Hope mine can help you!! Thank you!

Because there's still orange code electricity.

Yes. Burn your motherboard. (I chawu accompanied the stupid failure to unplug the power on a thunderous night, and the motherboard burned).

It's up to you

I often thunder and also surf the Internet

But it's closer, and I'll close it to Lei Da

Unplug the power supply 1

In fact, all the appliances in your home are the same

When thunder and lightning arrive

Will stare at the socks to affect the stability of the power supply or suddenly rise a few hundred volts to be sensitive You can tell me what is the effect of raising a few hundred volts Simply burn the power supply, or burn other opinions.

Heavy electrical appliances are violent

There are also people who are burned

It's all about safety.

Because lightning can not only be burned through the outdoor antenna into the internal circuit of your TV, but it can also have the opportunity to hit any transmission wire due to the strong current, and thus spread to the power line in your home and burn everything.

Of course, you may say that you have a good safety device, but the powerful current generated by lightning is instantaneous, and before your safety system is activated, such as before the fuse has time to blow, the high current has passed through the safety device and entered your home electrical system to burn everything!

Of course, this is only a risk, and although this is unlikely, it is best that you should turn off the power during a thunderstorm.

However, no one usually interferes with their daily life for such a small possibility, so they don't pay attention.

In fact, when thunder, if the lightning hits the wire line or ** line used in your home, the voltage will instantly rise to n million volts.

If your appliances are designed to work at this voltage, it's fine, if it's 220v, it will definitely burn out. For example, in thunderous weather, don't turn on the computer, and unplug all the power plugs of the computer, otherwise once the computer is struck by lightning, it will be too late to regret it.

Therefore, when thunder, the correct way is to unplug the power plugs of all electrical appliances. If you don't unplug it, it will burn out even if the power is turned off.

Lightning is an unknown voltage and current, and when lightning strikes all electrical appliances, the damage is generally great.

If you're lucky, you'll only burst the fuse, and if you're unlucky, it's all broken and it's hard to repair. Generally, lightning entering from the power supply is less hazard, because the power supply basically has a circuit design such as high-voltage protection.

However, lightning entering from cable TV and ** lines may cause great harm, such as network card burning or even motherboard burning, and *** machine bursting.

The main ways for lightning to enter are: power lines, ** lines, cable TV lines, water pipes, damp walls, etc. In addition, radio waves can attract lightning, so you should not receive a mobile phone during lightning, because there are many deaths caused by lightning in the world

There are many reasons why a computer freezes in the first place.

Improper BIOS settings or unsuccessful overclocking cause "freezes".

The BIOS can be restored to its default values by discharging the motherboard.

2. If there is a conflict between software and hardware or the system file is corrupted, resulting in a crash, try to reinstall the system to solve the virus in the 3 machines.

Press F8 to power on

Enter Safe Mode to try a full antivirus.

4. "Crash" caused by poor internal heat dissipation of the computer.

For example, it is caused by the CPU temperature being too high.

It is recommended to clean up the dust of the chassis and replace it with a larger fan.

5. Poor hardware quality will also cause crashes, such as memory.

What 6 hard drives have physical bad sectors.

Try it after fixing.

7. "Crashes" caused by other aspects

For example, the voltage is unstable.

Reduced CD-ROM readability, poor quality floppy disks, and so on.

8. The "crash" caused by the exhaustion of subsystem resources, for example, the CPU usage rate is 100/100, you can try to open some programs or replace the CPU to increase the memory.
