The computer heat dissipation is slow, the old automatic shutdown, the computer heat dissipation is

1. If the CPU core exceeds a certain temperature (the CPU surface is generally above 70 degrees at this time), the voltage will be automatically reduced

frequency, effective speed to reduce heat generation, at which point the performance has been compromised. You will feel slow and stuck. If the temperature continues to rise, it will automatically shut down and protect itself.

Note: The internal circuit of the CPU sends a shutdown command Different from the "overheating shutdown" in the COMS settings of the motherboard, it is set by the CPU manufacturer inside the CPU, and it cannot be changed by the user.

2. CPU is generally not a problem.

3. Solution:

First, check whether the power cord of the CPU fan is properly connected.

Second, clean the CPU fan, add a little lube, and reapply silicone grease (too much or too little will affect the heat dissipation!). ）。

Third, if there is no relief after reinstalling the cooler, consider changing the CPU cooling fan.

Fourth, add a fan to the case. (It's not that more fans are better, sometimes too many fans will cancel each other out).

Fifth, use monitoring software such as Everest and "Z**" to check the temperature.

Sixth, if you find that the temperature is not high, it is likely that the power supply is insufficient or the quality is not good. Re-purchase a good power supply.

You can go and change a CPU, you can change to a normal one but it's also very easy to use, such as a dual-core one, I'll use it again, if the conditions are good, you can also change it to a better one, I don't recommend a 4-core one, because it's very unstable. Then you can clean the CPU fan, you can get some lubricating oil on it, remember not to get too much, appropriate, and then remove the previous fan and replace it with a powerful one, so that your problem should be okay, if you can't get it, it should be your socket problem, you can check the line or socket. 、

The fan is broken. Put on some lube and let him spin faster.

Hello, you can refer to the following operation methods to assist the machine to dissipate heat1, use disk cleanup, and clear the system junk files.

2. Start --- running--- enter msconfig and uncheck all the unnecessary enablement items (such as msn qq, thunderbolt, emulet, virtual optical drive, etc.).

3. Detect and kill viruses and malware.

4. Check whether the heat dissipation vent is clean.

5. Whether the ambient temperature is too high, you can try to raise the laptop to ensure smooth airflow at the bottom and cooperate with heat dissipation.

6. You can consider buying a *** heat dissipation bracket to help the laptop dissipate heat.

7. Close some useless running programs to reduce the burden on the fan.

If none of the above methods can solve the problem, we recommend that you back up your data and restore the operating system.

If the fan is broken, just replace the fan.

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.

3.: Power supply issue. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small.

4: Software factors. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down.

If you are using Windows 2000 or Windows XP, it is recommended that you patch the blaster in time after using antivirus software, and the general problem can be solved.

The computer shuts down automatically for no reason.

5: Check whether the CPU is overheating and whether the CPU fan tray is stable, if it is broken.

Or it is unstable, can't hold down the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature is too high, the motherboard's automatic protection function will automatically shut down, and the CPU fan's screws are loose and early! 6: 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.

7: When the power supply of the host fails, or the voltage fluctuates greatly, add AC regulated power supply.

8: No, it is recommended to disinfect in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.

It is likely that the silicone of the CPU has dried up, and it is recommended that you remove the CPU fan and reapply the silicone to give it a try.

Replace the CPU radiator, the original one is not good,

1.Normal use in spring, autumn and winter; Prove that it is no problem to be hard or soft.

2.The old power supply is used normally in the computer repair office, and the new power supply has been replaced by a wide boy 3The fan dust has been cleaned and is working properly.

4.It rained last night, and it seems that it was no problem to play for more than 1 hour, but it will automatically shut down after about half an hour of play.

5.Today, the UPS Shante 500 has been replaced, and the problem is still the same, and it seems that the problem of voltage instability can be ruled out.

The above 2-5 points show that there is no problem with the hardware, it seems that you know a lot about the hardware, but I don't see you mention making the system above, and I don't know what the effect of redoing the system will be.

But according to you, the sudden shutdown should be a hardware issue.

Come on. Why doesn't anyone say it's a CPU issue?

Do you know why your CPU temperature is always high? Because your CPU is a copycat, or a refurbished thing. That's what my computer is.

Originally, there was a problem with the integrated sound card and I went to a small repair shop to repair it. As a result, the problem is solved, a new problem arises, and the CPU temperature is always too high. I can't get stuck.,Disassemble the machine to see the CPU....

It was replaced. Take a look at a regular store. Fake.

Changed to a ...Nothing.

Fake CPU to play games, the CPU will be high. The temperature is also high. In the summer, the weather is hot, and the height is even higher. So it shuts down automatically.

Try turning on the air conditioner. Guaranteed to be fine. Change the CPU....Accessibility.

You go to the BIOS to see what the CPU temperature is, and then look at the temperature of the CPU over-temperature shutdown setting, if the CPU temperature is normal (AMD's summer is below 65 degrees), set the CPU over-temperature shutdown temperature to 65 degrees. If the CPU temperature is not normal, check whether the CPU heat dissipation is normal, including the fan running speed, whether the fan and radiator are clean, and whether the heat dissipation silicone is dry.

It should be a hardware issue!

It is likely that the power supply of the motherboard is somewhere or the motherboard and the chassis are short-circuited!

See what is the CPU shutdown protection temperature of the BIOS!!

According to the reason you say, the main reason is due to high temperatures. Mildly, it will make the computer run slowly, especially in the hottest weather, the computer is very easy to crash, and the serious ones will not have a black screen, and the computer cannot be turned on. Solutions to avoid computer crashes on hot days:

1.If you have an air-conditioned room, place your computer in an air-conditioned room.

2.If not, place the computer in a well-ventilated location.

3.If there is no good position, then use an electric fan to blow on the computer (it has a certain effect, but after a long time, if the temperature is too high, it will not work very well);

4.Reduce the time spent on the computer in hot weather;

5.Use more internet at night (the temperature is lower at night than during the day), and don't spend less or too much time during the day.

In the summer, when playing 3D games, have you ever considered that the graphics card is overheating?

It's clear that it's time for the CPU fan to be replaced!

The ultimate cause is a voltage issue. UPS has little effect on voltage regulation. When the voltage is low enough to be outside the operating range of the UPS, the UPS is useless.

The UPS voltage regulation range is about 150V-270V. If it's not in this range, UPS doesn't do anything at all.

The voltage stabilization effect of the wide boy and the UPS is similar.

It is recommended not to turn on large electrical appliances. (You have a big factory near your home, or you live where you live, and there are a lot of people who use electricity, but you don't have voltage stabilization equipment.) ）

You think about it so much....My computer used to be in a similar situation to you, I thought it was the voltage was unstable, so I borrowed a voltage regulator and installed it, and the result was fine, and it won't automatically shut down and restart.

Clean. Connectors inside the machine).

Dusting. dust on the fan radiator).

Reapply the thermal grease.

I can't change the fan again.

There is a matching problem with desktop fans, and the higher the CPU frequency, the better the cooling fan is required. If you change the fan with a high frequency, the CPU will still be turned off. Intuitively and simply distinguish the good and bad radiators from the weight, or directly buy the expensive heavy ones of famous brands. The best is the all-copper one.

Reworked the system. Reason for automatic shutdown of the computer:

1.Poor heat dissipation of the main computer, power supply failure, and motherboard failure may cause the computer to automatically shut down or automatically restart repeatedly. (Reboot is an important feature: sometimes it shuts down, sometimes it restarts).

2.When the core components of the system are damaged, the running computer may automatically shut down. Kingsoft security experts are here to provide you with special killing tools and system repair tools, please click Fast**.

3.In the running software, there are some software with the option to shut down when the task is completed, and the user may not have noticed and turned these switches on.

These software are more common, such as Thunderbolt, Express, anti-virus software, BT**, **** and so on. In the software settings, there is an action that automatically shuts down after completing a certain task. But generally the default setting is off.

The purpose is to automatically shut down the computer when a task is completed when a task is running a more time-consuming operation.

4.Other hardware reasons.

The solution to the automatic shutdown of the computer:

1.First of all, check whether there is a problem with the hardware, focusing on the power supply of the motherboard, CPU fan, host power supply, and power socket.

2.Check if there are some applications that have enabled shutdown after the task is completed. This is evident from this. The feature is,Before shutting down,There will always be a program that finishes running,Generally, a dialog box will pop up to remind you to turn off the model。

3.Resolve virus Trojans and repair system damaged files. With the latest version of Kingsoft Poison Forest Rental Soba 2011, you can complete virus removal and system configuration repair at one time.

It is also possible that there is a contact short circuit on the motherboard, etc.! Sometimes even the power doesn't light up!
