My computer keeps appearing, and it s useless for me to turn it off

Friend, this is your computer "poisoned" after losing or "mistakenly deleting" the "System Files", or "System Files".

pieces" are "destroyed", I give you 7 ways:

Then click "Repair", "Select All", and then "Repair File"!

Again: "Recover Lost DLL Files", scan them out and recover it!

2。Use "360 Security Guard" to "Scan Plugins" and then "Clean Plugins" to remove it!

3。Then use "360 Antivirus Dual Engine Version", "Full Scan", Virus Trojan, and then click to delete!

4。After restarting the computer, go to "Quarantine" and click "Delete completely"!

5.Restart the computer, after booting up, press F8, press Enter, Enter, enter into "Safe Mode", and kill the virus!

6。Use "360 Security Guard" to "Fix IE", click "Use 360 Security ** Navigation", and then "All".

Select", "One-Click Repair", "Return"!

7.It really doesn't work, do a "one-click restore" system.

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

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.

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.

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.

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 system, it is recommended that you use antivirus software to patch the blaster in time, and the general problem can be solved.

Take a look at the power settings in the BIOS, because there is such a setting in the BIOS, which means that if the power is turned off when the power is suddenly cut off, it will automatically turn on when the power comes in, according to what you said, this may be turned on.

As for shutting down less than 5 seconds after turning on, it is because ATX motherboards are different from AT motherboards, AT motherboards can press the power button once when they are powered off, while ATX has to keep holding down the power button for 4 5 seconds to shut down. Because you shorted the 2-3 pins of PW-On, the problem you mentioned above will occur.

Clause.

1. The computer is poisoned by modifying the registry, and the boot script is automatically loaded, and the boot will be turned on.

Second, if it is a desktop, it may be that your voltage is unstable (this is generally not the case with laptops).

Clause. 3. When you install a certain software, there is an update system in the software, and it will automatically shut down (sometimes prompted).

Clause. Fourth, the performance of the computer or the power supply is poor, and there will also be an automatic shutdown.

Fifth, there is a problem with the fan, which cannot accurately sense the temperature, and then the other hardware is connected badly or broken.

Automatic shutdown or restart of the computer is a relatively common phenomenon of computer failure, and the reasons for this failure are generally as follows:

1. Poor heat dissipation of the computer (mainly CPU, motherboard northbridge chip and graphics card heat dissipation), resulting in automatic shutdown or restart;

2. The capacitance protrusion near the CPU of the computer motherboard is bulging, causing the computer system to be unstable and shut down, which is more common in AMD motherboards;

3. Hardware compatibility problems, mostly seen in automatic shutdown or restart during system operation;

4. Software conflict, when running a certain software, causing the system to shut down or restart;

5. The computer hardware or slot is loose, causing the system to automatically shut down, etc.;

First enter the system in Windows safe mode to disinfect, after the antivirus, if the problem is the same, please reinstall the system or have a backup to restore the backup!

Phenomenon: During the normal operation of the computer, the system suddenly and automatically shuts down or restarts the system.

1. Virus causes.

2. Turn on "Automatic shutdown and restart when the computer encounters a serious error".

3. Serious memory errors cause the system to crash (software problems).

4. Malicious program or shutdown

Phenomenon analysis: Today's motherboards have a temperature monitoring function for the CPU, once the CPU temperature is too high, exceeding the temperature set in the motherboard BIOS, the motherboard will automatically cut off the power supply to protect the relevant hardware. On the other hand, power management and virus software in the system can also cause this phenomenon to occur.

What to do: Use 360 security guards to investigate and kill first.

If the abrupt shutdown phenomenon persists, check whether the CPU heat dissipation is normal. Turn on the case to see if the fan blades are working properly, and then enter the BIOS option to see the speed of the fan and the working temperature of the CPU. If you find that it is a fan problem, you will carry out relevant dust removal maintenance on the fan or replace it with a better quality fan.

If you rule out the hardware cause, enter the system, overwrite the installation power management from the Windows installation CD, and then thoroughly check and kill viruses. When these factors are eliminated, the cause of the failure may be the aging or damage of the power supply, which can be confirmed by replacing the power supply method, and replace it with a new one if the power supply is broken, and it must not be used continuously, and the hardware will be burned.

It should be that the CPU is overheating, and when the computer is used for a long time and the heat dissipation is poor, it will suddenly shut down, my computer used to be like this. It is recommended to change the cooling fan of the CPU.

This ......Look at the kind of shutdown you are,First of all, you have to know a few questions,First,Whether the power supply is overheated,This is a problem that often occurs in crime,Shutdown,It's usually a drop.,The screen is black.,Clean up the dust.,It's usually a fan.,The second one may be a computer virus.,Usually many people will use this answer to be perfunctory.,And then let you find a better anti-virus software.,But usually a virus that can make you shut down directly.,Anti-virus software usually has no effect.,At this time, please reinstall the system.

Preferably, I can tell me the details of the situation, and the main thing is the detailed parameters of the computer

1. Is there a virus?

2. The heat dissipation is not good, but it is generally restarted.

3. Is there any software or plug-in that shuts down the computer regularly?

Press and hold the power button for 5 seconds.

Then the computer shuts down.

Press and hold the power button to power off. The last resort is to unplug the power cord.

It is recommended to reinstall the system with a 360 first aid disc or system CD.

Forced shutdown and then reboot, system problem.
