My computer turns on automatically! Why does my computer always turn on automatically

1.Maybe it's a Trojan, it's remote control, just reinstall the system.

Is it set to auto-start?

3.Or modify the Power Management.

It may be related to your "network card boot settings", you go online to search for the relevant information of the motherboard BIOS settings, and change the network card to boot automatically!

Maybe it's a Trojan, just reinstall the system.

Probably hit the back door. Let's reinstall the system.

Aging of the system or computer.

Solve it in the registry.

Enter regedit

Looking for... Khan: I can't tell.

Very well solved.

Is the BIOS set to auto-boot?

Shutdown and restart failure.

The fault is Windows

XP operating system shutdown failures are the most likely failures. The fault may be caused by the following reasons:

1) The system settings are adding to the chaos.

windows

XP automatically restarts by default when there is an error in the system, so that when the user shuts down, the computer will be restarted if there is an error in the system during the shutdown process. Disabling this feature often resolves the problem of auto-restart.

Right-click "My Computer" on the desktop, select "Properties" in the pop-up right-click menu, pop up the "System Properties" window, click the "Advanced" tab, click the "Settings" button in the "Startup and Failback" column, and the "Startup and Failback" window will pop up. In the "System Failure" column, remove the checkmark before the "Auto Restart" option and click the "OK" button.

2) Advanced power management in trick-or-treating.

As we all know, shutdown is closely related to power management, and the cause of shutdown failure is likely to be caused by poor system support from power management.

Click "Start Settings Control Panel Performance & Maintenance Power Options", and in the pop-up window, enable or disable "Advanced Power Support" as needed. If you're using Advanced Power Support enabled when a failure occurs, try to disable it, and if you are using Advanced Power Support to disable it when a failure occurs, the failure will often be resolved.

1. The driver is incompatible, which is mainly manifested by the rigid driver or the updated driver.

2. Hardware problems, including memory, power supply, hard disk and other problems.

3. Viruses and Trojans in the system cause the system to restart automatically.

The workaround for the computer to always restart automatically.

Through the above analysis, we can deal with the problem accordingly, first check whether the memory, hard disk, power supply, etc. are plugged in firmly, and then use the driver wizard and other optimization masters to deal with the computer driver, check whether it is caused by the incompatibility of the driver, and then use some antivirus software to check and kill to see if the computer contains viruses. After a step-by-step check, I believe that this problem will be solved soon.

Just set it up in the BIOS. In the power management settings, set the plug-in auto-start to disable.

Not caused by a faulty shutdown. And RPC has nothing to do with either. XP's virus does not affect the underlying hardware.

Also available:

1. Go to CMOS, in the power management menu, PME

eventwake

UP (PME event wake-up) should be disable, 2, click My Computer, Properties, Advanced, Settings, turn off the automatic restart function if the system fails. 3. The software is incompatible, which often causes the problem of shutdown and restart, which is a new mechanism of XP. Workaround:

Right-click on "My Computer" and select Properties. Select the "Advanced" tab, find "Startup & Failback", and click the "Settings" button next to it. Remove the checkmark before "Auto Restart" in "System Failure" (if you're using XP only, you can uncheck all the checkboxes you see, which will speed up the XP startup).

4. Enter the safe mode, if it does not restart after shutting down, continue to check the system reason, if it restarts after shutting down, replace the power supply.

2. How to turn off the auto-restart function.

windows

XP is an excellent operating system, but sometimes it has a little tantrum, such as automatic restart, which is an annoying glitch that many people have encountered. Because by default, Windows

XP automatically restarts in the event of a critical failure, such as a system or program that stops responding. In order to prevent automatic restart in this case, this function can be disabled. Here's how:

Open the Control Panel, select Performance and Maintenance System in the classification view to open the System Properties dialog box. Click the Advanced tab, and under Startup and Failback, click the Settings button. Under System Failure, clear the " before the Auto Restart check box

Click the OK button to exit the dialog box.

Note: You must be logged in as an administrator or administrators group member to complete the procedure.

Generally speaking, there are three scenarios.

1.Setup issues (mostly seen online).

Power on and press del to enter the BIOS first

Then select power

management

features

Then select Restore

onacpower

There should be 3 options inside loss.

Keep the machine in a shutdown state.

Keep the machine on.

laststate

Restore the machine to the state it was in before the power loss or outage occurred.

All you have to do is choose OFF or LAST

state on it.

2.Hardware conflicts (personal experience).

This is also the case with my computer.

According to the method on the Internet has not worked,Because it does not affect the use of the no longer care about it, I think it is my own motherboard defects,Later, after installing broadband (before the built-in cat dial-up Internet) once cleaned the chassis,Found a built-in cat that has been idle for a long time,It was unloaded,It turned out that the problem of calling on the machine was gone,It can be seen that it is a problem of hardware conflict。

3.Motherboard defects (this cause should be objective).

Do you turn on the power after shutting down normally, or do you only turn on the power after a sudden power failure? In the power management of the BIOS, the power-on is set to always turn off, rather than the last time or on.

The main engine switched on and off that UMC.。。。 Unplug the switch jumper. Tap on the main unit with a screwdriver, try to shut it down, and if the problem persists, reinstall the system.

Don't make it that complicated, first check if your power jumper is not connected incorrectly, if not, then you can take out the COMS battery and discharge it. Once you've got it, go in and set up the options for blos! The problem of automatic boot is gone!

Open your case. See if your CPU fan will spin. Generally, it is caused by problems with CPU heat dissipation. It is recommended to take the CPU fan out and then put it back on. You can also try another one.

It should be that the BIOS on your motherboard is set to reboot after the last illegal shutdown or power failure. The specific solution is best you find out the instructions of your motherboard. The above will tell you which one is this feature

There are many kinds of software to set up automatic boot, so I won't list them all.

There are several possibilities:

1. I made a task plan on the computer.

2. The computer is infected with a virus.

3. The BIOS power management item of the computer is wrong.

You jump the cable to turn on as soon as the power is on, and then you manually turn on the power.

1. Don't talk about the problem of optical drives, you can change it if you say it's aging.

2 and 4 are the same problem, both because the motherboard battery is dead, so the motherboard boss will automatically become the original setting, the time is not right, and the original setting of some motherboards is to automatically turn on when the power is on, so your computer will be plugged in and turned on. Solution: Buy a motherboard battery and replace it, and then look at the power source item in the motherboard settings, and set it to power on and not automatically turn on.

3. Is the memory you are talking about physical memory? Virtual memory is not the same as physical memory, and some software needs to be set up with appropriate virtual memory no matter how large the physical memory is. How to set up virtual memory:

Right-click on "My Computer", open Properties, then left-click to open "Advanced (or Advanced System Settings)", click Settings in the first column "Performance", and select "Advanced" in the pop-up window - Change to set the appropriate virtual memory, which is usually multiple the physical memory.

Check the power switch on the chassis first, and then try it on a different motherboard.

1. The inability to install the system is a problem with the optical drive.

2. The time display is not right, and the motherboard battery is out of power (you can enter the BIOS to set the time) 3. System Properties > Advanced > Performance Options > Advanced can set the virtual memory size, reference (initial size 1524, maximum value 3048).

Remember the last bullet point setting.

4. Plug in the power supply and turn it on by yourself, and there may be power problems.

Reference, hope it helps!

The computer is plugged in and turns on itself, I don't know what's going on?

There are two possibilities, either the incoming call power on function is set, or the anti-interference ability of your power supply is poor.

Look at what you wrote, it seems to be telling a joke, remember to see this kind of road number. There are many versions, and you can count this as one, and it's well written.

Some motherboards have an option "PWRON after PW-FAIL" in the "Power Management Setup" of the BIOS settings, and its default setting is "ON", set it to "OFF", and it will not automatically power on the next time it is powered on again. If you don't have this option, you can turn off the ACPI function in the power management and turn it on again, or turn it on if it's already off.

Most motherboards have an option in the BIOS: in the Power Management Setup, you can choose the status of the machine when it comes back after an unexpected power outage, whether it will automatically turn on, stay off, or remain in the state it was in before the power outage. Please set the auto-start to off.

In addition, poor quality of the power supply or motherboard can also cause similar problems.

It is recommended to install the system again.,I've encountered it before.,Changed the system version and it didn't appear.。

You can also turn off the Internet device and it will not appear. It may be a remote wake-up feature.

It's similar to my computer, the easiest way is to change the motherboard's battery, but virtual memory and memory are not the same thing, virtual memory is changed in my computer, right-click, properties.

There is no other reason for this, it is a problem with the motherboard battery.

If you have Windows Vista installed, the solution is to go to the BIOS settings, select "Power Management Setup" to enter the power management settings, and set "ACPI Function" to disabled, F10 to save.

Poor quality of the power supply or motherboard can also cause similar issues. The ATX motherboard needs to detect the level signal of one capacitor to boot up. If it is not guaranteed to be well connected at one time when the power is turned on, an instantaneous inrush current will be generated, which may make the power supply mistaken for a power on signal, resulting in a false start-up.

You need to turn it off, don't click until it is turned back on.
