Who knows what kind of bad fun it is for the computer to automatically shut down and turn on automat

First of all, see if it is a system (virus) problem, press F8 on boot and press the up or down arrow to let the system stay in the selected state or press delete to enter CMOS, see if it will restart, if the reboot has nothing to do with the system or virus, check whether the fan is installed (there is a problem with CPU heat dissipation), whether the power supply is reset or not, if not, add me QQ

1.There are two main reasons for the failure of computer self-start: one is that the BIOS is not properly set, when the timed boot function is set to "Enabled", the machine will automatically turn on at a certain time on a certain date.

In addition, some motherboards have an auto-boot function setting in the BIOS settings of incoming calls, if which digging is selected.

2.Click My Computer Properties Advanced Settings to turn off the auto-restart function under system failure. The reason for shutting down and then restarting is most likely related to the CMOS settings, enter.

3.The power supply is aging, or the power supply voltage is unstable, so try changing the power supply. Check whether there are bright and large power consumption electrical devices around.

Generally, the automatic shutdown may be caused by the high temperature caused by too much dust in the CPU fan, if so, clean up the dust of the CPU fan and heat sink, add new heat dissipation silicone grease, if the heat dissipation fan is broken, change it. If it's not a problem, it may be caused by problems with motherboard parts or power supplies, voltage instability, hard disk failure, hardware overclocking, etc., and the new hardware is incompatible. In addition, a Trojan horse can also cause a shutdown due to a system failure, but the probability of this is very small, restore the system or reinstall it (**Master Lu test the temperature).

If it automatically shuts down or standby without operation, it may be a problem with the settings. Right-click on the desktop to select Properties Screen Saver Power Supply Select a scenario that suits you from the drop-down list in Power Usage Scenarios, and set Never in the list of Monitor Off, Hard Disk Off, System Standby, and so on below (or set a suitable time).

Open the Control Panel, click Hardware & Sound on the left, then Power Options on the right Change schedule settings Select Turn off the monitor (select Never or Set time), select Change computer sleep time, and select Never or select the appropriate time (Win7 or Win8) from the drop-down list next to Make computer sleep.

See if it's caused by the settings above.

What do you do on your computer before or during the shutdown?

It could be that they are doing the trick.

1 The computer system is poisoned or infected with malware.

2 CPU Fan Bad CPU Temperature Too High, Overheating Protection.

3 The power supply is bad, or new hardware has been added, and the power supply is insufficient.

4 The graphics card or graphics card fan is broken.

5 The motherboard is broken, and the motherboard core is overheating.

Solution: 1 Check whether the antivirus software has killed the virus, you can determine, whether it is caused by the computer system poisoning or malware, if there is a virus, it is recommended to use a variety of antivirus software combination to kill the virus, or if it doesn't work, reinstall or restore the system, you can solve it.

2 **Master Lu software, test the temperature of each hardware of the computer, open the case, see if the CPU fan and graphics card fan rotate normally, find out the problem, and change the CPU fan. About 30 -100 yuan.

3 If the computer has a discrete graphics card, the power supply is not enough, then you can only change to a higher power power supply, the power supply has been used for a long time, unstable, then you also need to change the power supply to test.

4 Shut down, touch the south bridge, north bridge chip, graphics card chip of the motherboard with your hands, if it is very hot, it is likely to be broken and need to be repaired.

There are many reasons. Poor heat dissipation, running too many things, CPU usage is too high, and the inner card strip is loose or not good.

If it's timed to boot, that's the setting of the motherboard BIOS.

I accidentally changed it to automatic boot before, and the computer started up in the middle of the night.

Surprise me!

Analysis and answer to the problem of automatic shutdown of the computer:

1.: Poor heat dissipation. Due to the influence of weather temperature or the insufficient number of revolutions of the CPU fan, the system overheats, which will lead to the automatic shutdown of the computer, it is recommended to check whether the system temperature is normal.

2.: 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 in tightly with the motherboard, or you can change the socket to see if it is down.

3.: Power supply issue. The lack of power supply is also an important factor that causes the computer to shut down automatically.

4: 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, it is recommended that you use antivirus software to solve the general problem.

5: Check whether the CPU is overheated, whether the CPU fan tray is stable, if it is broken or unstable, it can't hold down the CPU fan, the CPU fan has insufficient heat dissipation capacity, the CPU temperature is too high, the automatic protection function of the motherboard will automatically shut down, and the CPU fan screws are loose and early! There is another important reason, the CPU fan silicone grease is gone, just add silicone grease.

6: It may be caused by the unstable voltage of the host, and it can be replaced.

7: When the power supply of the host fails, or the voltage fluctuates greatly, add AC regulated power supply.

Troubleshoot system issues. It may be that there is too much dust on the fan, which causes it to shut down automatically, and the solution is to clean up the dust and it will be normal!

The reinstallation system is ruined such as. If it is not useful, it is a problem with your hardware, if it is generally not too high, the fiber is a problem with the memory or motherboard.

If you have two RAM, just pull one of them and try the other.

Try using the installed version of the system disk, mine is the same. Also see if the cooling fan inside is broken.

Is it a normal shutdown? Isn't it an automatic restart?

Can you elaborate on the situation, such as under what circumstances it will automatically shut down? Can I turn it on again immediately after shutting it down? The laptop is still a desktop.

Is it a shutdown or an automatic restart?

Changing computers, it's not good to get old.

Some games are not running because the computer is too low, it is running at the frame rate, and the computer is not compatible with the game.

There is no graphics card body movement program.,Just install a 3dxi.。。 Find it online.
