What s going on with my computer always turning on automatically from time to time

You need to go to the BIOS to check the power configuration.

Computer power failure and voltage instability cause the computer to restart automatically, the following steps can solve the phenomenon of restart:

1. There are incompatibilities between systems or programs, press F8 to move to the advanced option when you boot up, and select "The latest correct configuration" to enter to repair, and press F8 to enter the safe mode to restore the system or reinstall the system.

2. The CPU or other hardware temperature is too high, and the memory and graphics card are incompatible or faulty.

3. If the hard disk has bad sectors, please use the system's built-in functions or software to repair the disk, or format the hard disk to repartition and reinstall the system.

4. Incompatible drivers can also lead to restarts.

5. The system file is missing, refer to the system ghost base installation tutorial.

Repair or reinstall the system.

6. Change the default automatic restart of the system: right-click on My Computer Properties Advanced Settings in Startup and Failure Recovery Remove the checkmark before "Auto Restart" in System Failure, and then press OK and Apply to restart the computer.

7. The configuration of the game is not suitable, the problem of the game itself, the hardware temperature is high, the environment on the computer is not good, the time period is playing, and the game is re-played, and it is always not good to play this game.

8. Don't operate the computer at full capacity, that is, when playing games, watching **, and watching web pages, it is easiest to crash, blue screen, and restart while doing other operations, so don't operate other things when playing games, watching **, and looking at web pages (this is the easiest to restart).

Here's how to fix it:Reason 1: Battery, power supply problems1, check all cables (including power plugs) to ensure that all devices are properly and tightly connected together.

2. Check whether the laptop has power (although most people will not make such a low-level mistake), because the notebook has a built-in battery, so it can be used without plugging in the power supply, of course, the time is limited, when the built-in battery is used up and not charged, it will cause the notebook to fail to turn on, at this time we just need to plug in the power to charge.

Reason 2: It may be caused by a virus infection, press and hold F8 to enter the advanced options page, select "Latest Correct Configuration", and then press Enter. After entering the system, run the anti-virus software, check and kill the virus, if there is a virus, restart the computer after the anti-virus, if it is not normal, it may be caused by the incompatibility of the device driver and the program, delete the graphics card, network card and other drivers, delete the driver and restart, if not, then rule out this reason.

Reason 3: Hardware problem: Disassemble the notebook to check whether the hardware is loose, generally the hardware is not plugged in well, there will be an alarm sound, the long sound continues to ring means that the memory module is not plugged in tightly, one long and one short means that the memory or motherboard has a problem, one long and two short means that the graphics card is wrong. If there is too much dust inside the notebook, it is best to clean it up first.

In addition, pay attention to whether it is caused by the new hardware, if it is normal before the replacement of the hardware, and it is not normal after the replacement, then check whether it is compatible. If it doesn't start at this time, it's best to send it for repair, and a professional will check whether there is a problem with your hardware one by one. Reason 4:

Display ProblemsIf the power supply** is working, but the screen is still pitch black, try connecting another monitor to your computer (you can borrow one if necessary) to make sure it's not a monitor issue.

1. First of all, enter the BIOS at the time of booting, here my computer is to press "F1" to enter the BIOS interface, there are certain differences between different Mingxing BIOS ("F2", "DEL", etc.).

2. Select "System Time & Date" under the "main" menu to enter the set time;

3. Set the system time.

4. Select "Automatic Power On" under the "Power" menu to enter the setting of the self-shielding grinding boot configuration.

5. In "automatic power on", select the automatic power on cycle in "wake up on alarm", <>

6. There are several options such as "single event", "daily event", "weekly event", etc.

7. If you select "single event", you will only set the boot time once, and you need to set the time point and date.

8. If you select "daily event", you can set it to automatically start at a certain point in time every day, and you only need to set the next time point.

9. If you select "weekly event", you will set the day of the week to automatically turn on at a specific time point and <>

10. At this time, you need to set the time point and the number of the week (such as: Sunday) to save and restart after setting the "F10", and when the set time comes, the computer will automatically turn on.

Generally, the fan does not dissipate heat well.

caused by CPU overheating and voltage instability.

First, check whether the lower fan is operating normally.

As for voltage instability, it is recommended to buy a voltage regulator (not UPS) or a 130 260V wide switching power supply. If the computer shares a power strip with high-power appliances such as air conditioners and refrigerators, the voltage supplied to the computer will be greatly affected when these appliances are turned on, and it is often manifested as a system restart.

It is advisable to separate their power lines. Thank you.
