What are the symptoms of a burnt motherboard and power supply?

I was automatically given out again, and I haven't finished answering yet!! The motherboard is more likely to burn, do you smell the smell of burning. It is also possible that the power supply has been broken down by several capacitors.

Since you are a newbie and there are no substitutes at home, it is recommended that you take them to a computer company. As long as the hard drive is fine, the data will not be lost.

It's a problem with the motherboard, and one of the boot chips on the motherboard is broken.

So what's the other way you can't check your computer for a few years? If it's more than 3 years, see if the motherboard battery is still charged. It won't turn on without power.

Try to change a battery first, 1-5 yuan a cheap, if not, send it for repair! Tell the service person not to move the hard drive. There are a lot of precious materials that cannot be lost!

If the motherboard and power supply are burned, you won't be able to turn on the computer, but don't worry, the hard drive won't be lost if it's fine.

It could be a problem with your computer's memory or a problem with your power supply.

The data will not be lost, the data is stored in the hard disk, as long as the hard disk is fine... If the power supply burns out, it is estimated that the operation will not be able to run.

Power supply or motherboard! There is more possibility that the power supply will be broken!

There is a high chance that the power supply will be damaged. The second is the motherboard.

The only most obvious symptom is that you can't even turn on your computer.

If there is a problem with the computer motherboard, it is possible to burn the power supply, and the excessive load of the motherboard will lead to the power supply load, that is, the instantaneous current is too large, and the power supply is generally over-protected so it is burned.

The board is generally a rectangular circuit board, on which the main circuit system of the computer is installed, generally there are BIOS chips, IO control chips, key and panel control switch interfaces, indicator plugs, expansion slots, DC power supply connectors of the motherboard and plug-in cards and other components.

The motherboard has an open architecture. Most motherboards have 6-15 expansion slots for PC peripherals to plug in control cards (adapters). By replacing these plug-in cards, the corresponding subsystems of the microcomputer can be partially upgraded, so that manufacturers and users have greater flexibility in configuring models.

If you don't have the hands-on skills, don't mess around.

Wait a minute, I won't give you a warranty.

If the motherboard is burned, it will paste off and have a burning smell.

It's just that the chicken box light doesn't light up, the fan on the motherboard doesn't reflect, and the power supply doesn't light up.

This requires further diagnosis, and a diagnostic card is recommended.

Generally speaking, the machine can't start, and all the hardware has been replaced but still can't. In some serious cases, you can smell mush, or you can see broken and leaking capacitors and other devices and paste spots directly on the board, but this is not absolute.

Burning does not necessarily mean that the outside of the motherboard is scorched or blackened, and the motherboard is not working, which is collectively referred to as the motherboard burned. The motherboard burns badly, and the CPU graphics card is not moving when the power is on. If only one component is burned, the blue screen of the display has no signal or the black screen has no signal.

If the motherboard is burned, there will be problems with the computer.

It may not turn on.

It may crash when you use it.

May be a blurred screen. Possibly. Anything is possible.

If there is anything you don't understand, you can ask me, or ask my team any questions in the future. (*Hee-hee.......)

Important problem, your machine is not grounded!

As for the reversal of the zero line of the live wire, there is no harm in this problem, the main thing is that there is no ground wire.

The easiest way, connect a cable on the computer case, one end to the ground, for your hard disk, there should be no parts replaced, you can go to get an individual mobile hard disk, replace the hard disk case to yours, see if the small hard disk inside is broken, so that it is convenient to make a decision, it seems that this computer is a heat dissipation problem, replace it with a new power supply, the power should be large enough, and then clean the dust, use an ohmmeter to measure the power cord of all equipment, see if there is resistance between the two fire zero wires and the ground wire, and determine whether there is any machine leakage.

As for the statement of motherboard leakage, I don't think it makes sense, the maximum voltage on the motherboard is 12V, and it will not be discharged to the ground, 1Motherboard capacitor burst is the most common motherboard failure, the fault is like the computer restarts from time to time, the system is unstable, because it is a power supply module, so if the capacitor drum is too much, it may be unresponsive to boot or no display of fan to display.

2.If the motherboard chip is damaged, it means that the boot is unresponsive or all fans are turning, and the display is unresponsive. In addition, if it can be turned on, it does not necessarily mean that the hardware is fine.

Starling? Even? Peony milk?

Kiss? Zinc Yunyun? Sprout from?

Sulk Lak? Allow the wine to be embarrassed and exhausted 2If the motherboard chip is damaged, it means that the boot is unresponsive or all fans are turning, and the display is unresponsive.

In addition, if it can be turned on, it does not necessarily mean that the hardware is fine.

If there is a short circuit in the motherboard, such as the MOS tube in the power supply part of the CPU is broken, then there will be no response when the power button is pressed, or the fan will stop as soon as it turns, this is because the power supply detects a short circuit in the output and the protection action is caused by turning off the output.

The motherboard of the mobile phone is burned, and the most serious consequence is that the mobile phone cannot be turned on; If it is light, it may cause some functions of the phone to fail.
