The computer automatically shuts down immediately after it is turned on, and the power supply time does not exceed 5 seconds.

The computer will not turn on and will automatically shut down as soon as it is turned on. Even the power supply will shut down within 5 seconds.

As far as I know, there are 4 reasons why computers automatically turn on and off

The first CPU is overheated (generally changing the CPU fan or putting a drop of oil in the fan will solve the problem)

Second power supply problem (ask an electrician to take a look)

The third virus (system)

The fourth memory is loose (insert and check to see if it is tight)

The main causes of Windows system shutdown failure are:

The selected sound file when exiting Windows is damaged; incorrect configuration or damaged hardware;

Incompatible BIOS settings, improper power management or interface settings, unassigned video card IRQ, incorrect program shutdown, loading of incompatible device drivers, etc. may cause conflicts.

Fault analysis and solution

1. The sound file is damaged when exiting Windows

First of all, you can determine whether the "Exit Windows" sound file is damaged; open the "Control Panel", open "Sound", and cancel the "Exit Windows" sound. If Windows shuts down normally, the problem is caused by exiting the sound file. To solve this problem, you can restore the sound file from a backup or reinstall the program that provides the sound file. You can also define "Exit Windows" to be silent.

2. Quick shutdown is abnormal

Quick shutdown is a new feature in Windows98, which can greatly reduce shutdown time. However, this feature is incompatible with some hardware and may cause the computer to stop responding. You can run "Msconfig" and disable fast shutdown in the "Advanced" options. If the computer can shut down normally, it means that the hardware device is incompatible.

3. Pay attention to "Advanced Power Management"

In addition, the "Advanced Power Management (APM)" function on the computer can also cause shutdown or black screen problems. To determine whether APM will cause shutdown problems, you can open "Device Manager" and open "System Devices". Uncheck "Enable power management" in "Advanced power management". If the computer shuts down normally, the cause of the problem may be APM.

4. Start-up and shutdown failure

We often encounter problems such as "You can safely shut down the computer" when Windows is just started, or it shuts down immediately when it starts or restarts when it shuts down. The cause of this type of failure is generally caused by damage to the Wininit.exe or Vmm32.vxd file. The solution is to retrieve these two files from the WINDOWS installation program compressed package. Place it in the Windows\system subdirectory, rename Vmm32.vxd to Vmm32.XXX for backup, then open "System Tools" and select "System Information"? ? In "System File Checker" in "Tools", select "Extract a file from the installation disk" and enter "Wininit.exe" or "Vmm32.vxd". Repeat this step to replace the file Wininit.exe or Vmm32.vxd.

4.There is a problem with Config.sys or Autoexec.bat

Extract a file from the installation disk

In addition, you can check whether there are conflicts in the Config.sys file or Autoexec.bat file. Use a text editor to check the contents of these two files to see if there are any redundant commands. You can also use "rem" to prohibit the execution of certain statements and gradually eliminate them until conflicting commands are found.

5. Check CMOS settings

Incorrect CMOS settings can also cause computer shutdown problems. You can enter the CMOS settings page when the computer starts, focusing on checking the CPU FSB, power management, virus detection, IRQ interrupt shutdown, disk startup sequence and other option settings. is it right or not. For the specific setting method, you can refer to your motherboard manual, which has very detailed setting instructions. If you really don’t understand the settings, it is recommended that you just use the factory default settings

My computer shuts down automatically as soon as it is turned on. What is the problem? The host is not hot either.

＂Reasons for computer automatic shutdown:

1. Poor heat dissipation of the host, power supply failure, or motherboard failure may cause the computer to automatically shut down or automatically restart repeatedly. (Restart is an important feature: sometimes shut down, sometimes restart)

2. Destruction by viruses and Trojans. When the core components of the system are damaged, the running computer may automatically shut down. Kingsoft security experts are here to provide you with special killing tools and system repair tools. Please click to download quickly.

3. Among the running software, some software have the option of shutting down the task after the task is completed. The user may not pay attention and turn on these switches.

These software are relatively common, such as Thunder, Kuaiche, anti-virus software, BT download, video playback, etc. In the software settings, there is an action to automatically shut down after completing a certain task. But generally the default setting is off. Its purpose is to automatically shut down the computer after completing the task when running a time-consuming operation.

4. Other hardware reasons.

Solution to computer automatically shutting down:

1. First check whether there is any problem with the hardware, focusing on the motherboard, CPU fan, host power supply, whether there is any problem with the power socket, etc.

2. Check whether some application software is enabled to shut down after completing its tasks. This can be clearly seen. The characteristic is that before shutting down, there will always be a program that has finished running, and usually a dialog box will pop up to remind you to shut down.

3. Solve virus Trojans and repair damaged files in the system. Using the latest version of Kingsoft Antivirus 2011, you can complete virus removal and system configuration repair in one go. "

My computer keeps restarting as soon as I turn it on

Please describe your problem in detail and at which stage the computer restarts.

1. The BIOS has just passed, the system self-test is completed, and a "beep" sound can be heard.

This situation indicates that there is no problem with the hardware and it is a system problem, then consider the system problem. Boot into the PE operating system from the CD and see if you can see the hard disk partition. If you can see the hard disk partition, just use Ghost to copy the gho file to the c drive and restart.

2. If the BIOS fails to pass, then restart, and you don’t hear the “beep” when the self-test is completed. Please unplug the memory and graphics card (if any) and wipe the golden finger (the golden socket) with an eraser before plugging it in to the motherboard. Also check whether the fan of the CPU or graphics card is spinning. If it is not spinning, It means that the motherboard may have poor heat dissipation and does not allow the CPU to start for safety reasons

3. Based on your simple description, I guess it may be a software problem. You look for the keyword "PE" or "micro" system in the CD boot interface. Enter the PE system according to the key in the keyword [], such as "B" or "1", and click "One-click installation to c drive" on the desktop. "That's it
