What should I do if the computer starts and gets stuck and restarts automatically?

Sometimes our computer will get stuck and restart automatically. What shall we do? Then let me tell you about the reasons and solutions for the automatic restart of the computer when it is turned on. I hope I can help you!

Solution 1: The computer will automatically restart after being turned on:

First of all, the reason of software can not be ignored.

The startup programs of 1.win200 and winxp were executed incorrectly, and then restarted automatically, but they still could not enter the system after repeated restarts.

Fault analysis: Under the default settings of win2000 and winxp, if there is an error in the execution of a program at startup, the system will restart and reload the program. If the program has serious problems, it will cause repeated restarts.

Known solutions: Press F8 key at startup-select Safe Mode-enter Control Panel-System-Advanced-select startup and fault recovery in the system, and finally remove the check box in front of automatic restart under the column of system fault.

Second, the hardware problem.

2. Power supply

Fault symptom: The system has CD-ROM drive and CD-ROM burner. When two devices work at the same time, automatic restart often occurs.

Fault analysis: Although the nominal maximum power of some power supplies can reach 300W, the actual power is greatly reduced. In addition, the current computer hardware consumption is large. When there are too many accessories installed in the computer, the output current of this kind of power supply will be more * * *, which will lead to the system restart.

Known solution: just replace the power supply with good quality.

Step 3 remember

Fault phenomenon: The system uses a large amount of memory and works normally, but it often restarts automatically when executing large 3D games.

Fault analysis: It is quite common that the system automatically restarts due to poor memory quality. And at present, many motherboards support dual-channel memory. If the quality and attributes of the two memories are different, the system may be unstable, especially when the system executes the Yamato program.

Known solutions: try to set the CL value of the memory to 3 or 3.5 in the BIOS, and appropriately reduce the FSB bus frequency of the system; If the memory works in dual-channel mode, it is best to choose products with the same brand and speed, so as to ensure the stable operation of the system.

4. Chassis power button and reset button

Fault phenomenon: The computer automatically shuts down or restarts at irregular intervals, and it needs to press the power supply several times. Reset the button or tap the chassis panel to resolve it.

Fault analysis: This is a hidden fault, which needs more time to check. However, this kind of fault often appears on computers that have been used for a long time. Usually, the button * * * is not elastic, or there is too much dirt between the button and the chassis panel, which leads to the abnormal position of the button, so it is automatically turned off or restarted irregularly.

Known solution: When the key can't return to the normal position, you can consider replacing the key element or cleaning the dirt between the key and the chassis panel with alcohol.

Solution for automatic restart of computer when it is turned on 2:

5. The motherboard BIOS setting is incorrect.

Symptoms: The system automatically shuts down after executing large-scale software for about 10 minutes. At first, it was suspected that the CPU temperature was too high, but the CPU temperature of the software test was still within the normal range.

Fault analysis: Now many motherboards have built-in control chips, which can automatically control and monitor the CPU temperature, and shut down if the temperature is too high. However, if the BIOS is set to the early warning temperature value, it will automatically turn off.

Known solution: enter the BIOS settings and appropriately increase the value of "shutdown temperature" in the "pc health" project.

6. Distribution frame problem

Fault: The computer host connects the printer, scanner and speaker through a patch panel, so it is easy to restart automatically when the weather is wet.

Fault analysis: Usually we use the patch panel to supply power to many computer devices at the same time. However, after long-term use of the poor quality patch panel, the elasticity of the jack becomes worse, and at the same time, there will be poor contact and fire between the plug and * * * due to corrosion, resulting in great changes in current. Once the stable implementation of the system cannot be supported at present, the above problems will occur.

Known solution: In addition to choosing brand-name patch panels with stable quality, it is best to separate the patch panels used by the host from those used by other devices.
