As soon as you press the power on button, what is the power off immediately about 1 second

Since it is not powered, it must have something to do with the power supply It is recommended that you first change the socket that is sure it is a good one, and try it, and change the power cord of the host before it is solved, and then you can only change the power supply If you change the power supply, you can only consider the problem of the motherboard. Everything you put on must be good. Generally speaking, there are only a few possibilities.

The power supply may be insufficient, or are you using a P35 board? Most p35s have 2 or n rebootsGenerally, the BIOS automatically restores the data after the main switch is broken

Is there any overclocking? If there is, it is most likely a BIOS restore. And the reason for the 2 restarts!

There is a good chance that it is a power supply issue.

There is a power supply problem, if there is a backup power supply you try to change it, the problem should be solved. This problem is that there is a problem with the power supply, I have done it in an Internet café, and this phenomenon often occurs.

Unplug the memory and plug it back in Try I've been in a similar situation.

It should be that the power supply of the host is broken, or ask a professional to open it for repair.

Like my classmate's, his graphics card is broken, and yours should also have a hardware problem, and the power protection will automatically power off.

After the computer is turned on, it is powered on, but it is automatically powered off after a second, and then it automatically starts to boot normally after a second or two. Is there a problem with this?

After the computer is turned on, it is powered on, but it is automatically powered off after a second, and then it automatically starts to boot normally after a second or two. Is there a problem with this? Hello dear, motherboard CPU over-temperature self-protection shutdown, check whether there is a gap between the CPU heatsink and the CPU or poor thermal conduction.

Apply the thermal grease and tighten the fan tightening bolts. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

Summary. No, no, don't cut off the power, you can't turn on the electricity, the power can't be discharged, you have to turn off the power to discharge.

The computer will automatically power off after a few minutes of powering on, and if it is turned on again, it will be flashed off for one second just after it is turned on, and it will automatically power off as soon as it is powered on. Turn off the power for a few minutes and then turn it on, but it still can't last a few minutes before the power is automatically turned off, continue the above process, and reciprocate.

Hello, glad to answer for you. In this case, it is generally the power supply on the motherboard, it may be a static electricity situation, you need to disassemble the computer first, unplug the memory module and the power supply cable on the motherboard, and then keep turning it on, put the static electricity, and then reconnect it back to power on to see how it goes, if it doesn't work, you need to replace the power supply of the case.

Let me try to unplug the memory and motherboard power, and keep the power supply of other parts connected, and try to turn it on without stopping?

No, all power is off first. Unplug the wires I said and don't power them on.

After unplugging, do not keep pressing the power button to discharge.

After unplugging the ones you mentioned, the total power supply remains disconnected, and it keeps turning on and discharging, right?

No, no, don't cut off the power, you can't turn on the electricity, the power can't be discharged, you have to turn off the power to discharge.

Still no, there is still this situation after discharging, I have a spare 600w power supply, try it?

Okay, let's try it first.

Summary. There are many reasons why your computer will lose power within a second or two of turning it on, and it could be a damaged motherboard, a loose memory module, and a malfunctioning power supply to your computer. If the computer motherboard is damaged, including the IC chip, capacitor burned, and the circuit has problems, the computer motherboard can be replaced in time, or sent to a professional maintenance network or contact professional maintenance personnel.

There are many reasons why a computer loses power after a second or two of turning it on, and it could be a damaged motherboard, a loose memory module, and a malfunctioning computer power supply. If the computer motherboard is damaged, including the IC chip, capacitor burned, and the circuit has chain problems, the computer motherboard can be replaced in time, or sent to a professional maintenance network or contact professional maintenance personnel.

Can you add, I don't quite understand it.

If the computer memory module is loose, you can pull out the computer memory module and insert it again. If it is a problem with the power supply of the computer, you should check the power supply cable or battery and other power supply equipment of the computer. In addition, during the use of the computer, it must be powered off in time, and the dust must be cleaned up in time, otherwise it is easy to have various failures.
