What is the problem with the automatic boot after 20 minutes after the computer is turned off 100

Power problem,You change it and try it.,Generally only automatic shutdown.,How can it be automatically turned on.,And it's fixed for 20 minutes.,That's right.,Is it occasionally or what?,There's an automatic boot in the boss.,But it's just a timing.,If you don't want him to turn on automatically.,It's good if the power is off.。

If there are no problems with the above, congratulations to the landlord for meeting the legendary beautiful ghost.

Have your computer turn on automatically at a certain time of the day? It may seem impossible, but it's actually very simple. Select "Power Management Setup" in the main BIOS settings page to enter the power management window.

By default, the "Resume by Alarm" option is off, move the cursor to this item, and use the "Pagedown" key to change "disabled" to "enabled", and the date and time settings that were originally grayed out under the "Resume By Alarm" option will be brightened. Move the cursor to "Date Alarm" and then "Time Alarm", and set it to "PageUp" and "Pagedown".

There should be a problem with the settings in your BIOS, just restore the settings.

Go to power management in the BIOS and wake up and turn off. I don't remember the name of the English option, but the last word is wake up your option, and you can find it and set it to off.

90% is a power issue!

I used to have such an experience, when I was not on time, mine was automatically turned on from time to time! And sometimes it starts up with a little sound! Just change the power supply!

Typical CPU heat dissipation problems, take apart the case and see if your fan won't turn when the machine is working. If you don't turn it, you have to see if the fan interface is loose or the fan doesn't work, and if the fan doesn't work, you have to change the fan.

Landlord, you might as well take apart your host and see if your CPU fan will turn or slow down.

This has something to do with the quality of the power supply and the short circuit of the switch.

One is the power quality problem; the second is the problem of short-circuit contact of the switch; The third is system poisoning and vulnerability problems.

Personal opinion one. Hardware issues:1

The rated power of the power supply is too small, so replace it with a high-power one. 2.The temperature of the motherboard is too high, and it will generally appear after overclocking, (it is recommended that the next Master Lu measure the temperature) If you have overclocked before, it is recommended to restore the field settings.

3.Generally, this situation is rarely seen when the computer switch (restart) button circuit is broken, but sometimes the switch is not in good contact and can also cause shutdown. 4。

The compatibility of each component (especially the memory), I don't know whether the user upstairs is a new computer, can not be determined.

Two. Software Issues:1.

It may be a 10-minute shutdown set by yourself (or through software), but the average computer user can't be aware of this. 2.There is a problem with the system, it is more complicated here, if you are using a pirated system, or a rookie, it is recommended that you directly redo the program.

3. The virus, if the virus is likely to be a worm, it is recommended to kill it with Rising, and it is really not possible to redo the program.

The computer shuts down automatically.

There are several main reasons:

Poor heat dissipation. Due to the influence of weather temperature or.

CPU fan.

The system overheats caused by insufficient revolutions, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

Memory reasons. When the contact between the memory and the motherboard socket is loose, it may also cause the computer to shut down automatically, it is recommended to check whether the memory is plugged into the motherboard.

Power issues. The lack of power supply is also an important factor in causing the computer to automatically shut down, but from this configuration, the possibility of this problem is very small. Slow.

Software factors. Computer shutdowns caused by viruses or Trojan horses also abound, especially the recent epidemic of shockwaves, which can cause the system to reboot and shut down. If you are using Windows

2000 or Windows

XP system. It is recommended that you patch the blaster in time after using antivirus software to solve the problem.

There are many reasons for the black screen, one is caused by a virus, try the whole antivirus, the second is a system problem, or there is a conflict between software and hardware, and the system can be solved by reinstalling the system, and the third is a problem with the graphics card, the graphics card driver is wrong or the graphics card is broken or the graphics card is loose.

Clean up the dust under the chassis, wipe off the gold finger of the graphics card with a skin like skin, and see if it is magnetized, 4 hardware problems, for example.

Memory sticks. cpu

Graphics. Mainboard.

and so on, whether there is looseness.

5 Monitor Issues.

The monitor is broken.

6. The hardware acceleration is set too high and exceeds the frequency range.

Click Windows Start Menu - Control Panel - Double-click the Show --- Troubleshooter tab, and under Hardware Acceleration, gradually drag the slider from Full to a position close to None-click the OK button.

The 7BIOS settings are incorrect or the overclocking is unsuccessful.

Caused by a black screen.

It is possible to reset the BIOS settings to their default values by discharging the motherboard.

8. The screen is black when the program is opened, for example, the game, one is that the graphics card does not meet the requirements of the game and is black, and the other is that it conflicts with the program, so it is black and crashes.

Hit Microsoft's black-screen plan.

It is recommended to reinstall the system.

There can be a variety of reasons for this, it could be a hardware conflict, a damaged motherboard, a damaged hard drive, or a graphics card problem, and your computer must be sent in for repair and a comprehensive diagnosis.

The laptop does not have good heat dissipation. If the temperature exceeds the protection value, it will automatically shut down, check the radiator. If the warranty period has passed, open it yourself, and if it hasn't, send it to the after-sales service department! Don't turn it on again. It is possible to burn out the CPU or motherboard.

The forcible shutdown system has a self-protection.

It takes a long time to turn it on.

No problem.

Complete. Hope it helps.

If you are satisfied with o(o....Ha ha.

Do you have any power mode set? Take a look at Power Management in the Control Panel.

In addition, it may be: 1. Check whether the CPU is overheated and whether the CPU fan holder is stable, if it is broken.

Or it is unstable, the CPU fan cannot be suppressed, the CPU fan has insufficient heat dissipation capacity, and the CPU temperature is too high, and the motherboard's automatic protection function will automatically shut down.

2. The capacitor of the motherboard is deformed, and the deformation may be caused by the unstable voltage of the host, so it can be replaced.

3. When the power supply of the host fails, or the voltage fluctuates greatly, the AC regulated power supply can be added.

4. No, it is recommended to use 360 Antivirus 360 Security Guard to repair it in safe mode, and it is not possible to disconnect the network and reinstall the system to eliminate system problems.
