The computer won t turn on and automatically restarts Emergency !! 25

There is a problem with the power supply.

It's normal. After the power supply is used for a period of time, the rated voltage output will decrease, and the power consumption is the most when the power is turned on.

Hehe. It's time to change the power supply.

If the boot screen is not displayed, it may be due to the memory, it may be that the motherboard battery is not powered, resulting in no alarm, and the factor that causes this may be the oxidation of the memory gold finger. Just wipe off the gold finger with a coarser piece of paper.

However, I think it is more likely that the power supply has become lower.

The temperature rises too quickly due to poor CPU heat dissipation, so the computer restarts to prevent overheating and damage to the CPU.

Replace the CPU fan or remove the original fan, clean and dry it properly and put it back on.

1. Check the power supply, mainly the socket for power supply to the CPU; 2. Check the memory module, clean up the dust, and eliminate oxidation; 3. Check the plug-in cable of the fan and the motherboard, and try other plug-in ports on the motherboard.

I've had a similar problem before, you see if the slot of the memory module is loose. If it's not such a problem, look at whether the motherboard has a capacitor burned, and if it's not a hardware problem, you can reinstall the computer system.

Definitely not a system issue. ~

You can consider whether the CPU is properly placed. Take out the CPU again and put it away to clean up the dust

Then the memory, the graphics card those, that eraser eraser cheats

If it doesn't work, it must be which capacitor of the motherboard is burned out> you can use the elimination method to try it, if you can, remember to add points to meHehe.

You can't pass the self-test,,? If it's not a problem, change all the pieces, start with the smallest hardware system and try to change them one by one to see which one can be started, which piece is the fault, because the machine is not with me, I can't say what the problem is.

Drain the CMOS first, and then try, otherwise it may be a hardware problem, try with a replacement method, such as a power supply.

Let's rebuild the system first and see if it can be solved, if it can't be solved, then it may be a hardware problem.

Either there is a problem with the system or a problem with the hardware, you can find an expert to show you

Press F11 to enter safe mode and then reboot.

Is the voltage stable? Unstable can't help it. Does the CPU fan turn? Do not convert. Hardware can also collide. Do the system. I've encountered it before. He changed the motherboard.

It may have been kicked somewhere on the computer.

What should I do if my computer keeps restarting automatically?

After backing up your data, format it entirely. There is no better and more thorough way.

Try to reinstall the system, if it still doesn't work, it may be a problem with the motherboard, and you need to send it for repair.

The computer always restarts automatically.
