After the computer is powered off, plugging in the power supply is not automatic boot, if so, rest assured that this is not a problem, it is set in the BIOS, just change it, the method is as follows:
Since we don't have a Weconex motherboard on hand, we can't give the exact BIOS setting menu name, the following is a list of corresponding settings according to the three common BIOS, please check the menu of the corresponding part of the BIOS settings for the motherboard, and sit down
1. First enter Power Management Setup (Power Management Setting) Power Again, which determines the state of the system power supply when the power is restored after the unexpected power failure at the time of boot. The setting values are:
Power off
power on
The last state enters suspended sleep mode, but if the button is pressed for more than 4 seconds, the machine shuts down.
Just change this option to Power Off!
2. First, go to the main interface of BIOS settings, select [Power Management Setup], and then select [PWR Lost Resume State], which has three options.
If you select [Keep Off], the computer will not start automatically when a call comes in after a power outage.
Select the [turn on] item to indicate that the computer will automatically start up when the call comes again after the power is off.
If you select [last state], the computer will be restored to the state before the power outage when a call comes back after the power outage. If the computer is turned on before the power is off, it will automatically turn on after the call comes. If the computer is in a shutdown state before the power is off, the computer will not automatically turn on after the call.
3. Some BIOS [Power Management Setup] does not have the [PWR Lost Resume State] mentioned above, you can find two options in the [PWRON After PWR-FAIL] [Integrated Peripherals] options: ON (turn on auto-boot) and OFF (turn off auto-boot).
4.When you're done, press F10 to save and reboot it.

I've encountered this problem with you.,At the beginning, I was like this, but my later became sometimes the boot display screen doesn't light up.,Mine is a power supply problem.,I took it to test.,CPU、Graphics card、Motherboard、There is no problem with the memory module.,Finally, you can change the power supply! You can put it to the test!
Hope it helps.

Let me briefly describe the problem of the landlord.
The computer is powered off by itself, that is, it shuts down at once, and there is no shutdown interface, is this the case?
And then the computer has its own boot?
In this case, it can basically be judged that it is a problem with the motherboard, you try to remove the dust, it really doesn't work, the battery is buckled, take care of the dust.
If it really doesn't work, send it for repair It's really a motherboard problem.
-
BIOS settings, do not restart after power failure, reinstall the system first, there may be system problems, do not rush to repair the motherboard.
-
Plug all connectors in the computer again, including the memory module, and make sure that the power ground cable is connected.

The computer will automatically power off after a while after starting, and the reasons are as follows:
1. The power supply is unstable, the voltage is not enough or it is broken.
2. Poor contact of the motherboard power supply.
3. The CPU conducts heat poorly, overheats, the CPU fan does not rotate or the speed is slow or even broken.
Solution: 1. Replace the power supply with a new one.
2. Make sure that the lines of the motherboard are in good contact.
3. Replace the CPU fan and coat the CPU with thermally conductive silicone, don't coat it too thickly.
The computer is automatically powered off when it is turned on
The specific situation is like this: turn on the power switch, press the power button to turn on, the fan turns, the machine has movement, and the power is off after a while, the fan does not move, the indicator light is not on, and it is useless to press the power button again. Turn on the power supply, and after a while, restart the power and repeat the above situation.
And after I power the hard drive, I can turn on the machine until it detects that the hard disk does not have this step. Sort out the optical drive power supply again, and after a period of nonsense, it can be turned on and work normally for a day (no longer without turning off). Excuse me, I don't want to do this every day, how can I solve this problem?
Solution: This situation of automatic power off after power on is likely to be due to a failure of the power supply or motherboard. The causes of the failure are varied, such as IC chips, capacitors burned out, problems with a certain circuit, etc., generally speaking, such a fault is not possible to repair the individual, it is recommended to send it for repair or replace the relevant accessories, it is recommended to try to replace the power supply first.
In addition, the power supply quality problems of the mains (such as low voltage, abnormal fluctuations, etc.) may also cause this fault phenomenon of power failure when the power is turned on.
The power-off fault may also be caused by the following reasons: first, there is a problem with the power switch of the case, such as the failure of the return spring, and second, the CPU is overclocked, or the CPU is a problem with the fan. Third, there are short-circuit faults in accessories such as optical drives and hard drives.
The computer is automatically powered off when it is turned on, and fault two:
The temperature drop may cause some problems that we can't figure out, so it is recommended that you open the computer case, unplug and install everything that can be plugged in and out of it, and see if you can solve the problem later.
Note: Under normal circumstances, the solution of automatic power off when the computer is turned on is that the power supply or motherboard is faulty. The causes of the failure are varied, such as IC chips, capacitors burned out, problems with a certain circuit, etc., generally speaking, such a fault is not possible to repair the individual, it is recommended to send it for repair or replace the relevant accessories, it is recommended to try to replace the power supply first.
In addition, the power supply quality problems of the mains (such as low voltage, abnormal fluctuations, etc.) may also cause this fault phenomenon of power failure when the power is turned on.
Your question is not very clear yet. Does the computer automatically start up after the power is off, and if so, then the problem should be that the computer restarts frequently. Reboot the computer itself: >>>More

There are two main reasons for the failure of computer self-start: one is that the B iOS is not properly set, when the timer boot function is set to "e nabled", the machine will automatically turn on at a certain time on a certain date. In addition, some motherboards have an auto-turn on function setting in the B iOS settings, if this function is selected, the machine will automatically turn on when the power is on. >>>More
I'm having the same problem with my computer as yours. The following 3 are the answers that others have given me to solve, so I'll show you. >>>More
You need to go to the BIOS to check the power configuration.
