Why did the computer shut down not long after it was turned on these days? Seek targeted and detaile

Auto Shutdown Troubleshooting Methods:

1. There may be a problem with the BIOS settings, enter the BIOS to restore the default settings or take out the battery of the motherboard, reverse the buckle discharge, and wait for 5 minutes to reverse install it. Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets.

2. If the computer shuts down automatically when using a certain application software, the automatic shutdown failure may be caused by this program software, and the program software can be uninstalled.

3. Then check the power supply, the power supply quality is poor, aging or the power is too small, which can not meet the power supply needs of the computer accessories, and the high-power and high-quality power supply can be replaced.

4. Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc.

5. Check the memory, the memory quality is not up to standard, poor heat dissipation, overclocking, mixing and inserting of different brands of memory and the CAS value setting is too low, etc., which can cause the computer to shut down automatically, and the memory parameters can be adjusted accordingly in the BIOS.

6. Check the motherboard, the motherboard aging, capacitor failure or pulp, the motherboard power pins, the motherboard and the chassis backplane short circuit can cause automatic shutdown, you can take the motherboard out of the chassis to check or test, then check whether the CPU fan rotation and the CPU temperature is normal, and then check whether the bottom of the CPU fan heatsink is dry, if it is dry, clean the silicone on the CPU fan, and then recoat the good silicone. If the fan is not normal, replace the CPU fan.

7. Cleaning method: It is a method to eliminate faults by cleaning the dust of the parts in the computer host. Dust is one of the factors that can also cause computer automatic shutdown failures, dust can cause parts aging, pin oxidation, poor contact and short circuit and other failures.

For these faults caused by dust, it is generally more effective to use the cleaning method.

8. The power supply system is unstable, which can also cause the occurrence of automatic shutdown faults, and a UPS backup power supply with voltage stabilization function can be considered.

1.It feels like your case is not cooling well.

2.When you use it, see if the fans of the cup and graphics card are running, especially when the computer is shutting down, maybe a fan is stuck and does not move, causing a rapid heating up.

Do you use a router with someone else? If so, you may be attacked by others. You're disconnected. Especially if you look at PPS is very fast on the Internet, people will of course hack you if they don't like you.

1.Use the latest virus database to check and kill the virus first.

2.Check the network cable interface to see if there is any poor contact.

1. Is there a problem with the power supply? Running out of power, or not being able to charge it can cause this problem.

2. Whether there is a problem with the system, it is recommended to kill the virus, check the Trojan, etc. If you can't solve it, reinstall the system.

3. Computer temperature problem, if the heat dissipation is not good, it is easy to have this problem. Use software such as Master Lu to test, and remove dust if the temperature is too high.

4. Some software can also cause this problem, please make sure that it appears after running a certain software. Uninstall or repair the software.

CPU heat dissipation is not good, change to a CPU fan.

Poisoned antivirus look at it If it doesn't work, it is recommended to reinstall the system.。。。

See if the fan is broken.

It is recommended that you replace the round battery on the motherboard, which is sold in the computer city, priced at 10 yuan, and changed to the motherboard after you come back, and boot it into BIOS. Restore factory settings, press F10 to save and exit. I can't do it, so I go to the computer city and ask the master there to help you, and the price starts at 30 yuan.

The automatic shutdown of the computer is mainly caused by the following reasons:

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. In addition, when the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, so it is recommended to check whether the memory is plugged in tightly with 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.

The computer shuts down automatically for no reason.

Suggestion: Reinstall the operating system first to troubleshoot system issues; Check the settings for CMOS power management; If the CPU fan does not have enough heat dissipation capacity and the CPU temperature is too high, the automatic protection function of the CPU and motherboard will automatically shut down without any reason. power failure; Or the power supply of the host is faulty, and the voltage fluctuates greatly, resulting in irregular automatic shutdown or restart.

Or the voltage of the external power supply is not stable, and the voltage supply can be stabilized.

The north bridge is generally quite hot, so focus on checking the CPU cooling fan and cleaning the dust between the gaps in the heat sink. If the fan is not good, you can change it.

Natsu was right, it was hot in the north bridge because he was busy.

The main thing is to touch the heat sink of the CPU is very hot, if it is a problem with the heat sink, change the fan, and generally solve the problem.

It should be caused by the failure of the computer's operating system, and it is recommended to reinstall the operating system to solve the problem and see if there is any improvement; Of course, the problem of the failure of the hardware itself cannot be ruled out.

Your IDE port is not hung with two devices.

Are you hanging two serial hard drives?

Generally, it is a motherboard quality problem.

Maybe there's something wrong with the computer program, and the computer will automatically detect it, so it's going to be slow.

There are too many add-ons in the system process! Generally, the system has just been installed, XP normal process 20-25 win7 win8 30-35, as you install the software, the more processes will be loaded, and the system is slower to boot or shut down.

The computer has been a little bit for a long time. If it's going to take a long time, reinstall the system. Usually install less irrelevant software.,Games.。

Even if you install it, select the software installation path to a disk other than the system disk (general C disk). You can also use hard disk software to check and repair the bad sectors of the hard disk, or move discontinuous files.

Reinstall the system, there is too much garbage in the machine.

There are too many things in the system disk of the computer.

It should be caused by the heat dissipation of the computer, and the computer will be shut down if the computer is seriously heated, and then it can be turned on after cooling.

Follow the steps below to troubleshoot:

1. First, check whether the CPU fan, graphics card fan, power supply fan, etc. are stopped, and whether the temperature of the heat sink is too high and cause automatic protection.

2. Check whether the power supply is insufficient, whether the power output is stable, and replace the power supply test, if the power supply is changed, it will be normal, and the power supply is damaged.

3. If the power supply is still the same when you replace it, consider reinstalling the system.

4. If you reinstall the system, you need to further check the motherboard, memory, hard disk and other hardware, and use the replacement method to determine the faulty hardware, and replace it.

1) Isn't that true for your computer? If not, how did you operate before the computer could not be turned off or was slow? What hardware has been installed, what is it, can you please tell me about it? (If there is an occasional shutdown crash, please press the power on and off button to turn off the power on).

If such a problem arises, the driver is not suitable, or the system problem is caused, can you restore the system, or not reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

If the shutdown is slow or the shutdown problem cannot be resolved temporarily, the shutdown is done. Right-click on the taskbar and select Task Manager, hold down the Ctrl key and do not move, and click "Shutdown" and "Close" on the Task Manager page with the mouse, then release the hand that presses the Ctrl key and wait for the shutdown (Win7 does not have this).

In terms of hardware, the CPU and other hardware temperatures are too high, unsuitable hardware is installed, inappropriate things are installed before the accident, or playing games, watching, or operating large programs, or the computer has been used for a long time, at this time it is very stuck, you have to have some patience and wait for the computer to recover slowly, click on every page on the computer to recover slowly, and then shut down after returning to normal, if it still can't, just press the power on and off button to shut down (if the computer is on for too long, my experience is, Restart the computer every once in a while, release the cache, and then play better).

2) If the above methods can't solve the problem, first soft and then hard, reinstall the operating system, do not install software, patches, drivers, etc., and see if there is still a problem with the shutdown? If you don't install drivers, patches, and software step by step, and find something that isn't suitable, don't install it.

Please note: If you restore the system or reinstall it, when installing drivers, patches, software, etc., be sure not to install the things that affect your accident, otherwise it will be restored or reinstalled in vain.

3) In terms of hardware, such as whether there is a problem with the hard disk, memory, etc., whether the temperature of the CPU and other hardware is high, if it is caused by hardware problems, it is recommended to overhaul it.
