How to restart the computer frequently restart the solution

The following are some of the host boot on some of the fault classification, phenomenon and solutions:

First, no display on the boot (divided into the monitor is not displayed and issued the alarm sound) completely did not display:

1, power supply has no work, to determine whether the power supply in the work can be inspected three places:

One, the power supply on the back of the cooling fan does not turn. Description: If the electricity

Good or bad, its cooling fan will not turn, but also may happen to be the fan itself is broken, it should also check other places to determine whether the power is broken.

Second, the power led on the mainframe panel of the computer is not lit. Instructions: The computer host on the LED indicator, indicating power, hard disk, floppy disk remote work, if these LEDs do not light, it is likely that the power supply is not.

Third, do not hear at startup when the floppy disk drive, hard drive or optical drive working sound. Note: When starting the computer will check these hardware devices, if they do not hear the sound, indicating that the power supply did not supply them at all.

2. If the power supply is not working, how to solve it? If the power supply is not working, do not think that the power supply is broken, you can check the following several places:

One, the total switch whether to skip electricity, whether the plug is loose, if there is an extension cord, you should check the extension cord fuse is burnt.

Second, the power supply is due to short circuit and stop power: Because the power supply itself is designed to detect short-circuit function, so it will detect the output of the circuit has a short-circuit, cut off all the power supply, it caused the power does not work. This condition can be seen by the cooling fan's operation, if the power supply is good, and there is a short circuit inside the mainframe, then when the power is turned on, it will be found that the fan turned to stop, and issued the voice of the AIDS, if the switch off after a while, the fan turned a few laps.

This symptom is a typical short-circuit phenomenon. To find the components that cause a short-circuit, remove all DC output connectors from the power supply, if all the connectors have been unplugged, the phenomenon of short circuit disappears, it represents a component of the circuit is short-circuit, can plug the connector back, until the short-circuit phenomenon occurs again, you can confirm that the component is broken, You can replace the component. Be aware that the power needs to be turned off before unplugging and inserting connectors to avoid burning parts of the computer.

Third, the power supply DC output is normal: If the above three points mentioned in the situation have been checked, the power is still not working, at this time can be used to measure the power of three meters DC output, if there is no output, said the power itself is broken, replace a power supply, should be able to solve

Software

1. Virus destruction

Computer viruses have come into being soon after computers. When the network becomes the information artery of today's society, the spread of the virus is more convenient, so it interferes and destroys our normal work from time to time. More typical is a period of time before the global computer caused serious damage to the "shock wave" virus, the attack will also indicate that the system will automatically start in 60 seconds. In fact, early in the DOS era there are a lot of viruses can automatically restart your computer.

For whether the virus damage, we can use the latest version of antivirus software for antivirus, the general will find the virus exists. Of course, there is also a possibility that when you are on the internet has been malicious intrusion into your computer, and placed a Trojan horse program. This allows the other person to remotely control all of your computer's activities, including, of course, getting your computer restarted. For some Trojans, not easy to clear, it is best to reinstall the operating system.

2. System file corrupted

When the system files are corrupted, such as the font under the Kernel32.dll,win98fonts directory under Win2K, and so on, the system runtime basic files are destroyed, and then it will not be able to complete initialization and forced restart. You can do a test, the WIN98 directory of the Font "FONTS" to try to change the name. When you turn on the machine again, our computer will continue to start repeatedly.

For this failure, you can only overwrite the installation or reinstall because you cannot get to the normal desktop.

3. Timed software or scheduled task software works

If you set up a reboot or load some of your work programs in the "plan taskbar" (computer shutdown), the computer will start again when the timing comes. For this situation, we can open the "Start" Item, check (computer automatic shutdown) surface has its own unfamiliar with the execution of files or other timed work procedures, shielding it and then power-on check. Of course, we can also in the "Run" (computer automatic shutdown) directly enter the "Msconfig" command to select a startup item.

Other reasons

1. Poor heat dissipation or temperature failure

CPU heat is not good, often the problem is the CPU heatsink fixed clamp off, CPU heat sink and CPU contact between a foreign body, CPU fan after a long time to use the radiator dust too much, these conditions will lead to poor CPU heat, excessive accumulation of temperature and automatic restart.

There is the CPU below the temperature sensor damage or p4cpu internal temperature of the circuit damage, the motherboard on the BIOS bug in a special condition temperature is not allowed, these will cause the host in the process of automatic protection restart.

Finally, we set in the CMOS CPU protection temperature is too low can also cause the host to automatically restart.

2. Fan speed failure

When the CPU fan's speed circuit is damaged or the speed line intermittent circuit breaker, because the motherboard can not detect the fan speed will be mistaken for fan stop switch to automatic shutdown or restart, but we check may see the CPU fan rotation normal, and the speed is normal.

Precautions:

Check motherboard, motherboard aging, capacitor failure or slurry, motherboard and chassis backplane, such as a short circuit can trigger a reboot, the motherboard can be removed from the chassis check or test, and then check the CPU fan heatsink bottom Silica gel dry, if dry, the CPU fan on the silicone clean, and then besmear the good silicone can be. Then check the CPU fan rotation, and the temperature of the CPU is normal
