Crackles when you try to turn on the monoblock?

Question

Iron

Hello.
The lenovo c540 monoblock worked for a couple of years, today it froze during operation and crackles were heard, then it turned off. When you press the power button, the indicator on the monoblock lights up, crackles are heard 12-13 times and it turns off.
What can be, what are the assumptions?
PS When loading a black screen, it does not reach the BIOS.

Answer 1

The fan sticks. Overheats and shuts down.
Whatever it is, you need to open it and look. Listen opened - where it clicks.

Answer 2

I'm guessing it's broken. Crackling noises can be caused by malfunctions in the high voltage circuits.

Answer 3

whiling away something on food. It’s better not to turn it on anymore and take it apart, see if it’s flashing on the board.

Answer 4

Well, open it up and see what crackles, well, what do we have to guess on the coffee grounds.

Answer 5

It may or may not be any moving part in the computer, or it may or may not be a high voltage breakdown ... I only know how to read photos
