The computer shuts down shortly after it is turned on, and what should I do if the computer shuts do

There are two situations when the computer is turned on and automatically shuts down

1. Hardware, 1, you open the case to see if the fan is rotating, or the speed is quite slow, because the CPU has an automatic protection function if the temperature is too high, if the fan does not rotate and the temperature is too high, so it will automatically shut down, [you can adjust the protection temperature specified by the BIOS, but novices are the worst not to set it].

2. The base of the CPU radiator is broken, which causes the combination of the radiator and the CPU to be not tight, the CPU protects itself, and it will automatically shut down a few minutes after powering on.

3. The power supply is broken, or the voltage is unstable, which will also lead to automatic shutdown.

4, Is the power switch good? Sometimes, after the power switch is pressed, it does not pop up [there is a problem with the spring], so it is always in the pressed state, so that it will automatically shut down soon after turning it on.

5. Check whether the hard disk data cable is well connected.

Second, the software, in this case, if you get into the virus, the system failure will also lead to automatic shutdown, if all of the above have been checked, or so, then you add me.

Try it out from the next system.

My computer also has a strange disease.,It's cold and it takes a few minutes to turn on the system normally.,Now it's hot.,There's no such problem.,NND it's still afraid of cold--

Haha, a hardware problem with the computer.

Did you change the power supply?

There may be too much dust in the case, but you can do what I say.

Don't mess around with yourself.

Go to the repair machine to understand that it may be poisoned

Analysis of the solution to the shutdown of the computer shortly after booting up

It is generally caused by the following reasons:

1. The computer system is poisoned or infected with malware.

2. The CPU fan is bad, the CPU temperature is too high, and the overheating is protected.

3. The power supply is bad, or new hardware is added, and the power supply is insufficient.

4. The graphics card or graphics card fan is broken.

5. The motherboard is broken and the motherboard core is overheated.

Solution: 1. Check whether the antivirus software has killed the virus, you can determine whether it is caused by the computer system poisoning or malware, if there is a virus in the past, it is recommended to use a variety of antivirus software combination to kill the virus, or if it doesn't work, reinstall or restore the system, you can solve it.

2. **Master Lu software, test the temperature of each hardware of the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and change the CPU fan. About 30-100 yuan.

Summary: CPU fan is broken, which is the most common auto-shutdown problem).

3. If the computer is equipped with an independent graphics card, and the power supply is not enough, then you can only change to a higher power power supply.

4. Shut down, touch the south bridge, north bridge chip and graphics card chip of the motherboard with your hands, if it is very hot, it may be broken and will be sent for repair.

Analysis of the solution to the shutdown of the computer shortly after startup II:

1.Poor heat dissipation. Due to the influence of weather temperature or CPU fan'If the system overheats due to insufficient revolutions, it will cause the computer to shut down automatically, so it is recommended to check whether the system temperature is normal.

2.Memory reasons. When the memory and the motherboard socket contact is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged in tightly with the motherboard, or you can change the socket to see if it is down?

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.

5.Check whether the CPU is overheated, whether the CPU fan holder is stable, if it is broken or unstable, the CPU fan cannot be suppressed, the CPU fan heat dissipation capacity is insufficient, the CPU temperature is too high, the motherboard's automatic protection function will automatically shut down, and the CPU fan screws are loose and early!

6.The motherboard capacitor is deformed, and the deformation may be caused by the unstable voltage of the host, so you can replace it.

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

8.No, it is recommended to kill the virus in safe mode, and it is not possible to disconnect the network and reinstall the system.

9.It may be that there is too much dust on the fan, which causes the automatic shutdown, and it is normal to clean up the dust!
