How does my computer automatically shut down after changing the CPU fan

1 Memory problems, pull out the memory and plug it back in, if it doesn't work, you can repair the place where the computer is repaired, it should be a change of inner memory.

The main reasons caused by hardware are: 1. Poor heat dissipation: the display, power supply and CPU will crash if the working time is too long.

Oil. Check the CPU temperature (go to BIOS or use CPU-Z), it should work around 35 to 60 degrees.

2. Dust killer: too much dust in the machine will also cause crash failure. Clean the chassis regularly.

3. Memory module failure: mainly caused by loose memory module and the quality of the memory chip itself, the memory module contact fault should be eliminated according to the specific situation, such as.

If there is a problem with the quality of the memory module, you need to replace the memory to solve the problem.

4. Hard disk failure: If the remaining space of the hard disk is too little and there are too many fragments, the machine is easy to crash when it is running. It is necessary to develop regular rectification.

A good habit of managing your hard disk and clearing junk files from your hard drive. If the hard disk is aging or caused by improper use, bad sectors and bad sectors should be used.

If the damage is serious, the hard disk can only be replaced. Other reasons 1. Incompatibility of software and hardware: 3D software and some special software.

may not be able to boot or even install normally on some microcomputers, find and remove incompatible software and hardware. 2. The driver is installed incorrectly.

When some hardware such as the driver of the graphics card is installed incorrectly, it will suddenly crash with a blue screen or black screen when the boot system enters the desktop.

Remove the problematic driver. 3. Defects in application software: If you run this kind of buggy software, it may make the system crash or not.

It can start normally, and in this case, you should find the latest version of the software or simply uninstall it. 4. Virus infection: virus Trojan horses, etc.

In order to make the computer work efficiency drop sharply, resulting in frequent crashes. At this time, we need to use antivirus software such as KV3000, Kingsoft Antivirus, Rising and so on.

to conduct a comprehensive investigation and anti-virus. Before you check for viruses, make sure that your antivirus software has an up-to-date virus database. You can click on "Upgrade".

button to ensure that the latest virus can be detected.

The fan is not installed properly, the heat dissipation is not enough, and the CPU temperature of the computer is too high. Caused by automatic shutdown protection.

Solution: 1 Use anti-virus software to check and kill the virus to see if it is caused by the virus.

2 **Hardware detection software, detect the temperature of each hardware, open the computer case, observe whether the CPU fan and graphics card fan rotate normally, find out the problem, detect whether the CPU fan is coated with silicone for heat dissipation, and the CPU fan is broken, which is the most common automatic shutdown problem.

3 Whether the computer is equipped with a discrete graphics card, the power supply is not enough, the power supply is used for a long time, it is unstable, and it may also cause automatic shutdown.

How to solve the problem that the CPU fan is still turning after the computer is turned off

Recently, a user said that after his computer was shut down, there was a problem that the CPU fan was still turning, and after waiting for a while, the processor radiator fan did not stop, so what should I do if the CPU fan is still turning after the computer is turned off? Here's how to do it.

Manner. 1. The motherboard BIOS is set incorrectly.

Generally, the CPU cooler fan is still rotating after the computer is shut down, and most of them are caused by the wrong BIOS settings of the motherboard. After powering on, press the DEL key on the keyboard several times to enter the BIOS, find the ACPI option in the BIOS interface of the motherboard, select [EABLED] with the up and down buttons, press [F10] on the keyboard to save the BIOS settings, or find "Load Default Setup" to restore the default settings of the BIOS. However, due to the different brands of motherboard BIOS settings, here is a simple way to restore the motherboard BIOS to the default settings, we need to open the main chassis, remove the round button battery on the motherboard, and then install it back to restore the BIOS default settings.

After we find the button battery on the motherboard, we will move the button outward, then the button battery will automatically pop out, the button battery will be removed, and we will install it in place.

Manner. 2. Select the high-performance power option.

Take win7 system as an example, we click on the "Start Menu" in the lower left corner of the desktop, and then click on "Control Panel", after entering the control panel interface, modify the viewing method to "small icon", find and click "Power Options", as shown in the figure below.

In the interface of power options, we can click [High Performance], and click on it to automatically complete the saving.

3. Caused by registry errors.

First of all, we press the "win key + R key" key combination on the keyboard at the same time to bring up the |Run, enter the command: "as shown in the following image."

After entering the command, we will enter the "Local Group Policyr" interface, we click [Management Template] - [System] in turn, and double-click the [Do not turn off the system power after the system shutdown occurs] option, as shown in the figure below.

In the interface that does not turn off the power of the system after the WIN system shutdown occurs, we click "Disabled" and confirm.

Fourth, hardware problems.

The biggest possibility is caused by power supply problems, there is also the possibility of motherboard problems, of course, if it is really caused by hardware, this small shortcoming is not recommended to be replaced, unless there is a warranty, every time the power is off.

The above is the shared way to get the CPU cooler is still turning after the desktop computer is shut down, and now you know what to do if the CPU fan is still turning after the computer is shut down! Generally, most of them are caused by problems with the motherboard BIOS settings, and I have encountered an old GIGABYTE motherboard before, and the CPU cooler fan will tremble after shutting down, and finally the motherboard BIOS is done.

1.In this case, it may be that the power of the CPU Fan you are changing now does not reach the original heat dissipation energy, so the CPU chooses to automatically shut down.

2.Before replacing it, confirm the voltage of the CPU FNA rotational speed. It cannot be lower than the original specifications.

3.Or your CPU fan is not installed properly, and you need to apply thermal paste when installing the CPU.

It may be because of the overheating protection, the overheating protection half automatically shuts down and the computer can't start up immediately after shutting down! If it's overheat protection, then see if your CPU fan speed is too low, or not fixed properly, and if the silicone grease is applied just right!

It may be that the radiator is not installed properly.

You can go into the BIOS and look at the temperature of the CPU.

Or the next everest and Master Lu will take a look at the system temperature and fan speed.

The fan is not installed properly, resulting in poor heat dissipation.

The CPU temperature is too high and the automatic shutdown is protected.

I guess it's not installed in place, check it carefully.
