After the computer is newly installed, it will automatically shut down after a few minutes of turnin

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.

2.Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

3.Power issues. 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.

Hehe, the upstairs is very funny, do you mean that people don't have enough heat dissipation because of the installation of fans?

It may be that your power supply is not working, or your power supply is too small. I have had a similar problem before, with the addition of an optical drive, it will not work when reading the disc, people say that it is because the load of the power supply is increased when reading the disc, and the power supply is solved.

Do-it-yourself? Check it, one is whether the thermal conductive silicone is coated well, and the other is to confirm that the fan is rotating after turning on (open the case to see).

Summary. Hello, happy to answer your questions. Usually the motherboard is faulty or the power supply itself is faulty.

This situation is usually due to a faulty motherboard (damage, short circuit, etc.) that causes the ATX power supply to protect itself and not work, or the power supply itself is faulty and does not work.

What's the deal with the automatic shutdown of the cooling fan as soon as it is turned on?

Hello, happy to answer your questions. If you don't take it, the motherboard is faulty or the power supply itself is faulty. In this case, it is generally due to the faulty motherboard (damage, short circuit, etc.) that causes the ATX electrical inspection to be faulty due to my protection, ignorance, or the power supply itself is faulty and cannot work.

Recommendation: In this case, it is best to replace and test with a normal power supply.

There are many reasons for the black screen to boot:

When we turn on the main unit, the power light is also on, but the monitor is black, there is no display or something similar to none.

Hints of signals.

1. The host does not start at all. Solution: Check if the wire plug is plugged in properly.

2. Is the power supply of the host broken? Solution: Replace the power box.

3. The CPU does not work if the contact is not good. Solution: Remove the fan and heatsink and pull out the CPU to clean up the dust, and then put it back in.

Note: The CPU has positioning, and it cannot be hard put in).

4. The signal of the bad host of the graphics card is not displayed. Solution: If your motherboard has a built-in graphics card, remove the discrete graphics card first.

Then connect the monitor cable to the motherboard's built-in graphics card and try to turn it on. Judging that it is rough and does not work, try to change the graphics card.

1), discrete graphics card poor contact (2), discrete graphics card cheat oxidation (3), high-end discrete graphics card may be electric.

The source power supply is insufficient (try to replace the high-power power supply) (4), the independent graphics card slot is too dusty (the solution is basic and inside.

The deposit note issue is pretty much the same). 】

5. Memory digging strip failure. Solution: Pull out the memory stick, use a soft eraser to wipe the gold finger on both sides, and insert it back.

6. The motherboard is broken. Solution: Pull out the memory module, if the power starts, if it alarms, the motherboard and CPU are good, is the memory module bad.

The graphics card is bad, replaced.

7. The system is broken. Solution: Reinstall the system without a bridge.

8. It can't be turned on after updating. Solution: Shut down and then restart, keep pressing F8 to enter the Advanced Menu, and select Safe Mode.

After entering the Safe Mode desktop, uninstall all patches of the update, then shut down and restart, enter the normal mode, and turn off the update.

9. The motherboard is damp. Solution: Remove the hard disk, memory module, ***-ROM and bake in the oven at 35 degrees for 10 minutes.

Take it out and blow the dust off the motherboard with a tubing gun.

10. The monitor is not. Solution: The power cord is not plugged in and reseated again.

12. Static electricity appears on the motherboard. Solution: Power off the main computer first, then find this button battery on the motherboard and take it out.

Come on, leave it for a minute. Then put it back in and turn it on.

None of the above will turn on or show up. Try to do it.

Let the after-sales take a look, just bought, don't toss it yourself, there is a warranty.

It can't be that the CPU fan is not plugged in, right?

The fan is not installed properly. Have you ever applied silicone grease? Open Master Lu to check the CPU temperature, it must have soared unlimitedly.

If the temperature is normal, it belongs to the motherboard boot control, and the accepted current is unstable. There are 2 situations that lead to 1Your chassis power failure, 2Your motherboard is faulty.

The workaround may be a bit difficult for you. You have to find a case power supply that is fine, change it, and try it if it works. It's the problem of the power supply, and the other side is the motherboard capacitor, so it's better to take it out and let the repair shop check it.

I can fix the lack of materials myself, please give me the answer. Thank you.

The automatic shutdown of the computer is mostly due to poor CPU heat dissipation, resulting in automatic protection and power off and shutdown.

In the past maintenance experience, this situation is generally caused by the following reasons:

When changing the fan, the thermal conductive silicone was not applied or applied unevenly.

When changing the fan, the adhesive tape or plastic box at the bottom of the fan was not removed.

The fan power connector is not connected to the CPU fan.

The fan speed is insufficient, resulting in insufficient heat dissipation.

The fan is not installed properly or the base is broken.

Please check one by one to troubleshoot.

If the fan doesn't turn off automatically before it is replaced, you should still suspect that the fan is not installed. The main thing is to see whether the silicone grease on the CPU is evenly coated, whether the silicone grease has solidified and dried, and whether the fan speed is normal and whether the air volume is large enough. You can go into the motherboard BIOS and look at the CPU temperature, if it is above 70 all the time, it will easily cause the shutdown.

The fan may not be installed properly, or there may be a problem with the fan. When the temperature is high, it will automatically shut down to protect the hardware from burning out, and it is still in a protective state before the temperature is completely lowered, so it can't be turned on. You need to wait for the temperature to drop to a safe value before you can turn it on.

You should be more detailed, you are changing the fan, whether it is the CPU or the graphics card. If it's a CPU, then it's your fan that isn't in place, the silicone isn't coated well, and it's possible that your fan motherboard doesn't recognize it, try a different fan, there should be a hint. If it is a graphics card, then the fan is not good, the speed is not enough, and it does not play a role in heat dissipation.

The problem may be that the thermal grease on the CPU has not been cleaned up when replacing the fan, because the silicone grease has become hard, and the newly installed heat sink cannot be in good contact with the CPU, resulting in the CPU overheating protection shutdown, and it can only be turned on again after a period of natural cooling. You can remove the fan first, carefully clean the residual silicone grease on the surface of the CPU, because the silicone grease on the original fan has been destroyed, you need to apply new thermal grease. Pay attention to the installation method.

Open the case and turn it on to see if the fan is working properly.

It's not that your silicone is not applied correctly.

Try plugging and unplugging the memory module.

Is your fan connected correctly?

If the connection is incorrect, the motherboard will monitor the rotation of the fan, and if it finds that the fan is not rotating normally, it will generally give an alarm, or shut down directly.

And you can open the chassis to see, after the boot of the ** condition.

When you installed the fan, did you encounter any other equipment, causing an abnormality?

Does it mean that you can enter the system or not?

Because there is an automatic power-off protection function in the motherboard BIOS settings, that is, when the computer is overloaded or encounters other situations that damage the CPU or system, this information will be fed back to the motherboard chip in time and react, because the BIOS is set up with this protection function, so in order to protect the CPU from damage, the system will automatically power off.

Your computer should be cleaned of dust or the fan is not running well, which usually occurs when the CPU is overheated or the CPU is overloaded due to the computer running for a long time. Excessive dust and improper fan operation will lead to poor heat dissipation and overheating of the CPU, which will trigger the automatic power-off protection function. If that's the case, just fix the heat dissipation problem!

1.Take out the battery of the motherboard, buckle it back, and discharge it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2.Sweep the dust inside the chassis to eliminate short circuits or poor heat dissipation caused by excessive dust.

3.See if the CPU thermal grease is dry, silicone grease is used to improve heat dissipation capacity, if there is no silicone grease, the heat may not be dissipated, and the machine will automatically shut down. Note:

If there is too much thermal grease and it is too thick, it will form a film in the middle of the contact surface, which will hinder the direct contact of the metal, which is worse than not applying thermal grease.

4.Think about it, is the fan size or fan power enough for a high-end computer? First consider the size of the fan (the bigger the better), then the power (the bigger the better), and the manufacturer.

5.Other objective reasons, such as high indoor temperature, running large programs (games) for a long time when booting up, poor heat dissipation of the case, poisoning, CPU usage often 100, etc. You can install Windows Optimizer, in addition to the software can comprehensively clean and optimize the system, it can also detect all hardware and software information of the system, you can detect it at any time, and compare it with the previous information, from which you can find problems.

If it can't be turned on properly after the power is off, it is estimated that there is a problem with the hardware or system files.

First, use the replacement method to rule out hardware issues (mainly check the motherboard and power supply).

After the hardware is eliminated, it is a system problem, and it can only be solved by reinstalling the system.

Frequent automatic power outages can cause harm to computer hardware, and the consequence is to shorten the life of the hardware.

The CPU temperature is too high to protect, and the dust inside the fan is clogged. Clean it up.

The computer shuts down automatically for no reason.

1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. 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.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to use 360 Antivirus 360 Security Guard to repair it in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.
