Give high marks! What s wrong with my computer keeps restarting and shutting down? Please help

There are many ways to make this phenomenon happen, and I will tell you a few of them, and you can try them one by one.

1 Virus destruction.

2 The voltage is unstable.

3.Poor quality of socket strips or electrical outlets, poor contact.

4 The power socket of the motherboard has false soldering and poor contact.

5 Memory corruption.

6 Poor heat dissipation.

Generally speaking, if this is always the case, the problem is more in the case of hardware. You can try to enter the safe mode, if not, it is recommended to repair, after all, the notebook is not as simple as the desktop structure.

1.First of all, discharge the computer, remove the battery, and press the power button.

2.Check whether the fan and CPU heat dissipation and temperature are normal.

3 into PE to try.

Force shut down first,,, don't let him continue,,, and then, the easiest thing is to reinstall the system (pay attention to back up important data or data before installation),

The switch is broken, and it can't be snapped back in time when it is pressed, resulting in this.

You may have accidentally pressed to reinstall the system while shutting down, just choose to restart manually.

Open the case and see if the fan is turning, and the high temperature of the graphics card's power supply will also cause the phenomenon you said.

Check the power cord to check the memory for dust! If it doesn't work, the system will be restored.

Re-recover the system and take a look.

Reinstall the system and you're done!

This is a very classic fault, and we can solve it in a way that goes from soft to hard. The first is the problem of the operating system, by default, if there is an error in the system when the machine is shut down, there will be no prompt, and the machine will automatically restart. At this time, you can right-click "My Computer", enter the property item, find "Startup and Failure Recovery" in the "Advanced" tab, right-click the "Settings" option, and uncheck the "Auto Restart" in the "System Failure" in the pop-up window, so that if it is the cause of the system, a blue screen will appear when the shutdown is made, and you can know the cause of the error by noting down the shutdown code.

Next is the BIOS settings, make sure that there is a "PME" in the BIOS

evenwake

up" is already "disable", or all auto-wake options are set to "disable". If none of the above measures work, it can be determined that the power supply or motherboard is faulty, and it can be checked with the replacement method.

Or: viruses.

When the "Shockwave" virus occurs, it will also indicate that the system will automatically activate after 60 seconds.

The Trojan takes control of everything on your computer from a remote control, including getting your computer back up.

Remove viruses, trojans, or reinstall the system.

2 System file corruption.

System files are corrupted, such as win2k, win98

The fonts in the fonts directory and other basic files of the system during the system run are corrupted, and the system will be forced to restart because it cannot complete the initialization when it is started.

Workaround: Overwrite install or reinstall.

3 Timing software or scheduled task software works.

If you set up in the Schedule Taskbar to restart or load certain workers, the computer will start up again when the scheduled time comes. In this case, we can open the "startup" item, check whether there are any executable files or other scheduled workers that we are not familiar with, block them and then boot them to check. Of course, we can also directly enter the "msconfig" command in "Run" to select the startup item.

Start - Run.

In the System Configuration Utility panel, select Advanced, check Disable Rapid Shutdown, and then restart your computer.

Run regedit

Find fastreboot on the right side

Key-value data: 1--- Rapid shutdown allowed.

0--- Rapid shutdown is prohibited.

Save and restart your computer.

The computer also has a near-forgotten feature--- System Restore.

It's that your system is hardware incompatible.

You're going to have to try a different XP.

I also encountered it last time.

Fortunately, I'm a computer businessman.

Then it was finally ok.

In the BIOS power options, turn off the NIC activation option;

In Vista, reset the following network cards: only the network speed and duplex mode are turned on, i.e., performance optimization is turned on, and the rest is disabled.

There are many reasons for the problem of not being able to shut down and restart, it may be software or hardware, if it is a software problem, it can be solved by reinstalling the system, if it is a hardware problem, then you have to find someone to fix it.

A bug with the chassis switch can also cause a restart.

The reasons for this situation are generally as follows: First, the motherboard BIOS battery is dead, or the CMOS detection is wrong. The second is that the device settings in the BIOS are incorrect, for example, the floppy drive is not connected, and you have set up the floppy drive in the BIOS.

Of course, the specific way to deal with it depends on the specific reason when you are prompted to press F1.

Press the "Delete" key on startup to enter the BIOS:

1.Turn off the floppy drive.

standard

cmosdrive

a：none

2. Change the battery.

Is it a direct power shutdown or what?

If the power is cut off directly, there may be a problem with your power supply.

The display is broken, I have such a situation in my family, it is recommended to go and change the graphics card quickly!!

Did you buy it not long ago?,If so, then the CPU is fake.,My friend also has this kind of problem.,After I know it, they don't care.,There are a lot of reasons for the blue screen.,He will go blue when he installs the software.,It seems that the computer itself wants to debug it to be incompatible (that's how mine is)

In the process of using the computer, many people have encountered the situation that the system automatically restarts for no reason, in fact, there are many reasons for the computer to restart, among which the hardware reasons are roughly as follows: 1Power supply is one of the biggest suspicions that cause the system to automatically restart Inferior power supply can not provide enough power, when the number of devices in the system increases, the power consumption becomes larger, the voltage output of the inferior power supply will be sharply reduced, and eventually lead to the instability of the system work, automatic restart phenomenon. Excessive voltage fluctuations can also lead to damage to hard drives and other devices.

2.Memory issues can also cause the system to reboot There is a relatively high chance that a memory error will cause the system to restart. In addition to ruling out poor contact between the memory module and the socket, a quality problem with the memory itself should be suspected.

In addition, setting the CL value of the memory too small will also cause the memory to be unstable, causing the system to restart automatically. 3.In addition, if your computer shares a power strip with high-power appliances such as air conditioners and refrigerators, the voltage supplied to the computer will be greatly affected when these appliances are started, which is often manifested as a system restart.

The best solution is to equip the computer with a UPS to power the computer, and pay attention to other electrical appliances so that they are no longer connected to the UPS. 4.Poor contact of the power socket After the power socket is used for a period of time, the elasticity of the reed is slowly lost, resulting in poor contact between the plug and the reed, the resistance is constantly changing, and the current fluctuates, and the system will naturally be very unstable, once the current does not meet the minimum requirements for system operation, the computer will be restarted.

The solution is to buy a good socket with good quality. 5.The temperature of the system is too high At this time, you should check whether the CPU fan is running normally and whether the heat dissipation conditions are good.

Today's motherboards have the function of detecting the CPU and system temperature in the BIOS through a special control chip. If you find that the temperature is too high, you should replace the fan or add one. 6.

Hardware compatibility problems are generally caused by the compatibility between the motherboard and the memory module, but the author has also encountered the example of the graphics card causing the system to constantly restart, and this fault disappeared after the hardware transformation and the graphics card AGP 4 function was blocked. Therefore, when you buy new accessories, it is best to try them before buying.

Frequent automatic shutdown or restart of the computer may be caused by the following reasons, please check them one by one:

1.Insufficient voltage instability or virtual connection of the line will lead to shutdown, and will also damage the computer, depending on whether the power supply in the machine is sufficient.

2.The power supply or CPU and other components do not dissipate heat well, the CPU is overheated (more than 60 degrees is not good), self-protection power off, please clean up the dust in the chassis, change the fan (3-4 thousand rpm), in addition, the CPU secondary cache is damaged, and there will be problems when using the computer to draw tables, **, graphics, etc.

3.The memory is too small, mismatched, memory quality issues, or not plugged in properly (poor contact between the gold finger and the slot).

4.There is too much garbage on the system disk, the registry is wrong, or there is too much garbage, please fix it.

5.The configuration of the motherboard, CPU, graphics card, etc. is too low, and it is time to upgrade (don't overclock at will, it hurts the computer).

6.There are viruses, Trojan horses or system problems, including system files that are damaged and need to be cleaned up or reinstalled, and some games or programs will cause memory conflicts and shut down.

7.If the boot area of the hard drive is logically faulty or physically damaged, try to repartition the system - low-cell repair - reinstall the system.

8.See if you have the scheduled shutdown software installed, it's working?

9.Problems can occur when the environment is too dry or wet, is there a strong magnetic interference?

1.system, you try to reinstall the system. If the problem is still a hardware problem.

2. In the case of general automatic shutdown, hardware.

The power supply is likely to fail and the power supply is insufficient.

Heat dissipation: There is a problem with CPU heat dissipation, or the north-south bridge chip is overheated. The motherboard's overheating program will open and shut down automatically.

Hard disk: Bad sectors, generally blue screens. It is rare to restart automatically.

There is relatively little memory, and it is generally a blue screen. It is rare to restart automatically.
