The computer is broken, the computer is broken, and the master speed is in Ah T T

There are too many problems with not being able to turn on. I guess it's the power supply.

I think you should test the temperature of the CPU with your hands.

Such a problem should be that the CPU fan speed is not enough.

These weather is hotter than teaching

It may be that the fan is overworked and burned, so it's better to change it

Let's see if we can

If the power is on normally and the motherboard light is on, it means that there is nothing wrong with the motherboard and power supply!

The CPU is a very sensitive thing, and if the temperature is too high, it will automatically shut down! If it's serious, you can even burn the CPU out! The situation of the landlord lawsuit should be a similar problem! It's all because the CPU temperature is too high!

Change some new salmon glue + change the fan to make the CPU heat dissipation better! The problem should be solved!

Power supply problems, reboot jumper short circuit, or, your fan is dusty and won't turn up, causing the CPU temperature to be too high.

First check if your external power supply is powered on!

Secondly, open the case again, turn on the computer to see if the CPU fan is turning, the motherboard indicator light is not on, if it is not on, the preliminary check should be the power burned!

If the fan is still running, nothing is broken, but the capacitor is broken, and it is OK to change it for 5 yuan

Believe it or not, whatever you want.

Is the memory module loose?

Check that your electrical outlet is powered on.

According to your normal shutdown, there should be no problem with the machine.

Or reinstall the graphics card, memory, sound card, etc. Or take it to the computer city to repair.

It should be a matter of hardware, go to the professional to repair it, it shouldn't be a big problem.

It is recommended that the customer service send it for repair, and the specific reason cannot be known according to the situation you provide. It is likely that the connection between the motherboard and the LCD is damaged due to a fall, and the function key is damaged.

It is recommended to go to the after-sales service to do an inspection, the hard drive and the graphics card are likely to have contact problems.

What model is your computer? Install a super rabbit on the computer to detect the hardware, graphics card, sound card, or whatever、、、 or send it directly to the after-sales service, as long as it is within the warranty period, they will definitely deal with it.
