The computer automatically restarts irregularly, and the computer always restarts automatically, and

Your problem is a bit complicated, there are many reasons, I seem to have encountered the same problem before, and I have checked a lot of information on the Internet, looking at your own analysis, I put forward the following doubts:

1. If there is such a problem when browsing the web, it is likely that there is a problem with the network card or network card driver, when the network traffic is too large, for the network card that is already a little problematic, the compound is too large, and the computer automatically checks the error and restarts. It's the same with drive issues. It is recommended to reinstall or upgrade the network card driver first, the network card is integrated, just reinstall all the drivers of the motherboard.

If it's a problem with the network card itself, then it's time to detect.

2. There is also a high possibility of memory problems, it should be said that there is a small particle in the memory that is broken, of course, the computer can basically run, when the memory is too large, and the memory including the bad particles needs to be called, there will be a problem, and it must be restarted. It is recommended that you change the memory to see, and this problem still occurs.

3. Then there is the compatibility problem between the software you installed and the computer, or the compatibility problem between the software and the software, see what software you have installed after the problem, uninstall it to see if the problem is solved, and if not, reinstall the system to see.

4. As for what kind of heat dissipation poisoning and the like, it seems unlikely to look at your own description.

Specifically, go out step by step, and send it for maintenance if it doesn't work. In addition to the first point of the network card itself problem, try what you can do first, the network card itself can only be repaired to know.

Look at what you add, it's basically certain that there is a small problem with a certain hardware, you change the graphics card to use it, and see if you say that there may be a problem with the graphics card. Also, I dismantled the computer and reinstalled it, which is really strange.

Based on your above situation, we see the possible reasons: 1There's something wrong with your system. Or the system and hardware are not compatible.

It is recommended to reinstall the system.

2.Graphics card issues. Graphics card glitches often cause reboots. Individual stand-alone games have high requirements for graphics cards. Accept.

The damaged graphics card can't be processed for a while and reboots.

3.Memory or CPU....

Personally, I think the system and graphics card are more likely!

It should be too hot, you see if the case is blocked by something in the heat dissipation area, or the cooling fan is too dusty, clean it up.

It may be that the pure contact is not good.

What software did you press? Got a virus?

There are generally the following reasons for this situation:

1. It may be that there is an incompatibility between the system or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter the repair, and it is not possible to press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the check mark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

Please go to the computer city and try to replace the power switch of the case, mine was repaired like this.

There are several possibilities.

1. The advantages and disadvantages of the power supply system are directly related to the normal operation of the computer and the safety of the components, for the computer, the voltage and the size of the current are quite sensitive, due to the current power network of many provinces and cities in China, the voltage is unstable, and the voltage difference between the peak and trough of electricity consumption is very large, therefore, it is recommended to measure the power supply voltage with a multimeter, if the difference is too large, it is necessary to consider the use of AC power regulator.

2I carefully checked every accessory of this computer, and found no problems, after starting the computer for a period of time, I touched the heat sink of the CPU with my hand.

3. The memory is too small.

If the computer is infected with a virus, press F5 to enter the network security mode when you boot it, use 360 security guard, and try to kill it!!

Reworked the system.

It should be that you have installed some incompatible software.

Hit the virus. Hurry up and reinstall the system.

I also had this problem with my computer a few days ago, and it has something to do with the hardware.

See if the power button doesn't pop up completely?

May be 1. Poor heat dissipation, it is important that the CPU is well ventilated. Working too long can also lead to: CPU heat dissipation problems are also an important cause of computer failures.

2。There is too much dust inside the case. Please clean it in time and keep the inside dry and clean. 3。It may be that the memory module is loose, and it should be pulled out to check whether it is damaged.

Aging or improper use of hard drives is also one of the reasons. Professional software can be used to troubleshoot the problem, and if the damage is serious, the hard disk can only be repaired or replaced. 4。There are compatibility issues with hardware and software. 5。If the memory usage is too large or the memory space is too small, it needs to be replaced.

End unnecessary programs or low memory configuration.

5。There are logical or physical bad sectors in the hard drive.

6。Virus. Infiltrate the anti-virus software.

7。If there are too many junk files or fragmented files, it is recommended that you clean up the system junk regularly. You can also restore the system, which is convenient and easy.

9.Reinstall the system.

Copy must be reported.

Shame on copying.

When measuring the temperature, you need to open the game or the program you usually run to measure the actual temperature and see if the temperature has soared!

It should be a bad heat dissipation, open the case, clean up the CPU inside, the dust on the graphics card fan and the power supply, if it doesn't work, you have to replace the CPU fan with a little more power, there are a lot of problems recently, all of them were used in the past, the fan power is small, and cheap accessories are used for heat dissipation, in addition to the current online games, the computer has been running for a long time, useless system garbage, more dust, running large online games, etc., the CPU occupies a lot, and it can't be quickly dissipated, The CPU temperature is too high, causing the computer to restart for no reason.

Not the cause of poisoning and voltage! It's a problem with the motherboard.

Three methods, must work, 1: hardware problem: you first try to take out the strip head to blow the dust in the slot clean, and then rub the contact piece of the strip, and then install it.

2: Software problem: Hold down delete on startup, and then come out n more English to choose a boot, this is the priority starter of the town date, change the first one to VCD-***, then press f10 to save, automatically restart, put the system disk into the system, 5 minutes of travel to get the software problem, I'm in Wuhan, a disk is only 4 yuan!

Personally, I think that those pirated systems are better than the genuine ones.

Some. 3: If you look at the two main fans, the CPU fan and the graphics card fan, if one of the fans does not rotate, it must be a problem.

It should be that the heat dissipation of the machine is too poor.

Look at the shouting to see if there is obvious dust in the vents around the machine, whether there is dust on the CPU inside the case, whether there is a lot of dust on the power vents, and whether the power supply fan is normal or not.

If there is dust, clean it up.

This Zheng Qingli sometimes obviously affects the performance, and at a certain time, it will make you unable to turn on the machine.

Optimization Master or z**.

When measuring the temperature, you need to open the game or the program you usually run to measure the actual temperature and see if the temperature has soared.

What are you doing on your computer when it restarts, can you tell us about it? I'll tell you what you say more accurately.

Please tell me about your performance before restarting, and your operation, it may be the restart caused by some operations of this limb, please ask me if you have any questions (I will re-educate you according to the information you provided).

Generally, the restart is caused by your own incorrect operation, remember not to do the operation that is easy to cause the restart. The computer should not operate at full capacity, that is, when playing games, watching **, **, and watching web pages at the same time, it is easiest to restart, freeze, and blue screen, so don't operate other things when playing games, watching**, **, and watching web pages.

No matter what you're doing, as soon as there is a sign of a card, stop the operation at hand and exit the trial, so that it won't restart, and if it's still like this, don't play or crash quickly.

In terms of hardware, the temperature of CPU and other hardware is too high, the memory is less than the card, the hard disk is bad, the voltage is unstable, and the hardware is not suitable.

Win78 can run the most basic is 4G memory,XP is 2G memory,It's easy to double,If you don't use this number,It is recommended to add memory (this is the number of practice,Not the number of theory)。

Boot and reboot have something to do with your improper operation before shutting down, right? For example: playing games, watching **, operating big things, and using the computer for a long time caused by the card, right? Or install something inappropriate, the failure won't happen for no reason, right?
