When the computer is turned off, it can t be turned off from the beginning

The software you use is relatively safe.

In your case, it is possible that the following are possible:

1. The computer's switch is damaged.

2, coms setting error Solved: Go to coms to find power managerment power after pw-fall and select off

3. The aging of the power supply, 4, the machine automatically restarts when a program fails, and the machine automatically restarts Solved: My computer --- the Advanced --- Startup and Failure Recovery bar --- settings --- unchecked"Automatic restart"Before the checkmark OK.

5, CMOS discharge 1, find the jumper cap on the motherboard, put it in a clear place, and put it back for a few minutes.

2. Take the motherboard battery down and use the driver to short the +-pole of the battery for about 10 seconds.

The above personal opinion.

Some Trojans can't be deleted, and if the things in them are very useful, use one click to restore, the best way to reinstall the system.

Reinstall the system and disinfect the software before installing it.

Is it an 8738 sound card installed, or some other hardware? Take the new one off and take a look.

Delete the software and try it.

In the event of such a failure, it should be considered from the following aspects:

1. Excessive dust accumulation. The computer cannot dissipate heat normally due to excessive dust accumulation, and the high temperature makes the computer work abnormally and causes it to freeze. Therefore, regularly dust the computer, reapply CPU silicone grease, etc., to ensure that the computer heat dissipation is normal.

2. Fan failure. Observe the CPU fan, whether the graphics card fan is working normally, and replace it in time if there is an abnormality.

3. Sometimes some viruses will run programs infinitely in the background, causing the computer to be paralyzed. Using anti-virus software, upgrading to the latest version of the latest and skin, and then "checking and killing" the computer can completely remove the hidden danger of the virus.

4. Insufficient memory. The memory capacity is too small, but when the machine is shut down, because of the need to carry out a large amount of work to protect the skin and store the data, it is likely to cause the situation of stuck, and the memory can only be upgraded to meet the demand.

5. Hardware failure. For example, power failure, motherboard circuit failure, virtual problems, etc. You can go to a professional computer repair center to have your hardware replaced.

Hello 1, this may be caused by too many caches or too many background service items.

3. Use the computer manager - clean garbage function, select all garbage, and clean it with one click.

4. Then use the PC Manager - PC acceleration function, according to the PC Manager prompts to optimize all service items with one click, and then restart the computer, and the shutdown will not appear in the future.

If you have any other questions and problems, please come to the computer manager business platform again to ask questions, and we will do our best to answer your questions.

It may be that you have a lot of background programs, and you can't close it at one time, so it is recommended that you use system optimization software to optimize it, and hope to adopt.

That's when you didn't quit something. Or just quit and can't handle it for a while. It's okay.

There are many files, and the system needs to be cleaned up, so it can't be closed at one time, and you have to wait a little longer.

1.Click "Start Settings Control Panel Power Options Advanced Power Management" and check "Enable Advanced Power Management Support" if your machine supports advanced power management features;

2.Click "Start", and run "regedit", then find PowerDownAfterShutdown in hkey local machine software microsoft windowsnt currentversion winlogon and set the value to 1;

3.The reboot will be successful.

Note: If your machine doesn't support advanced power management, unfortunately you'll have to manually cut off the power when the system is turned off and says "It's safe to shut down now".

Another: Wonderful way to solve win98 me can not shut down.

Both Win 98 and Win Me have such a problem: when the system is used for a period of time, when the system is shut down, it will stay on the screen of "the system can now be shut down normally", and the system can only be shut down by manually pressing the power button of the case.

Many newspapers and magazines have provided solutions to this problem, which can be summarized as follows: install Microsoft's shutdown patch, check if the advanced power option is turned on, and check whether the shutdown sound file is corrupted. However, the author's many experiments have proved that when this happens, these methods may not be effective.

The author's original solution was to restore the system with ghost, and then figured out the following method, which is simple and practical, and is now organized into a document.

1.Create a new text file and rename the file to ". The next step is to replace the system-generated file with this 0-byte "file".

2.Press "Start Run" in turn, enter "sfc" in the "Open" dialog box to run "System File Checker", click the "Extract a file from the installation floppy" option, press the "Browse" button, select the newly created "file" just now, press the "Start" button, then the "File Extraction" dialog box will appear, enter the directory where the file is located in "Restore From", such as "C:", or press "Browse" on the right to select; In the "Save File To" section, enter "System Drive Letter Windows" directly (you can also press the "Browse" button on the right to select); Once you have filled in both fields, press the OK button and start replacing the newly created File with the System Itself. During this process, there will be a prompt of "whether to back up the original file", just press the "skip" button. Finally, when the dialog box asking you to restart the machine pops up, press "Yes", and the computer can be shut down normally after restarting.

If the fault is not eliminated after following the above methods, please first rule out the shutdown sound effect file corruption and other factors. If it still can't be solved, then please press the "F8" key when booting up, select "Safe Mode" in the boot menu to boot, and then restart the system again.

The reasons why the brain can't turn off are generally as follows:1The auto-shutdown procedure in the system files is defective.

In order to determine whether this is the cause, the following experiments can be performed. Enter the command "rundll32 ,exitwindows" in Start Run to see if it shuts down properly.

If the shutdown can be performed under this command, it means that the automatic shutdown program may have some kind of defect. If patching the file still doesn't solve the problem, you can only reinstall the system. If you can't shut down normally by running "rundll32, exitwindows", it may be that some system programs in the system are defective, but the solution is still to patch the system or reinstall the system.

2.Viruses and defective applications or system tasks may cause shutdown failures. First of all, check for viruses and close all applications before shutting down the computer.

Since some applications are loaded at system startup, you can subtract the loaded programs one by one from the Startup menu (enter the command: msconfig in Start Run) to see if there are any files that affect the shutdown (of course, it will not take effect until after a restart).

3.Peripherals and drivers are not compatible well and do not respond to rapid shutdown. You can enter the command in Start Run:

msconfig", select "Advanced" in the "General" tab, and "Disable Rapid Shutdown" in the window that opens. If you suspect that the peripherals are faulty, you can also uninstall the peripherals one by one to check them so that you can find the affected peripherals.

4.If you set up a sound file to be used when Windows is shut down, it can also cause the shutdown to fail when the file is corrupted. Please select the "Exit Windows" item in the "Control Panel Sound Events" and set the sound name to "None".

If you can shut down normally after this process, it means that this is indeed the cause and you can reinstall the sound file for use.

5.WinXP can't shut down automatically after installation, if you rule out the above reasons, it may be that the power options in its control panel are not set correctly, please check your settings to ensure that ACPI and APM can work normally. There are also cases where the APM (Advanced Power Management) and Win XP in the motherboard system BIOS are not fully compatible (especially AMI BIOS), so they cannot automatically shut down.

Selecting Shutdown turns into a reboot of the system, in which case you can only manually shut down (press the power switch for 4 seconds and then let go, if it is less than 4 seconds, it will be invalid). The fundamental solution to the problem is to upgrade the system BIOS of the motherboard to a new version.

There is a background operation, you can end it in the task manager, run msconfig, and turn off the boot and boot when you don't use it. Clean up the system junk. Anti-virus.

If it can be shut down for a long time, it means that your system has a problem, there is junk or a lot of software, and the shutdown is too slow;

If it has not been shut down for a long time, it means that there is a serious problem with your system, resulting in a shutdown failure;

It is recommended to use 360, Kingsoft Guard, etc. to repair the system, and then clean up the system software and on/off programs, it will definitely be fine. Not a big deal.

In general, there are many reasons, both hardware and software. Here's how:

Go to the control panel, enter the system maintenance, and the automatic update will be turned on.

Wait for the yellow sign on the taskbar to disappear before shutting down, and you'll find that your computer will automatically install updates when you shut them down, and your computer will shut down when you install them during the shutdown process.
