pc does not start anything

[cobito]

It would be strange for the affected component to be the stack. In the vicinity of this, the following is seen:

Basically, there are 5 capacitors, 5 or 6 integrated circuits, an oscillator, and various SMD components. If I had to bet on something, I would say that the heat is affecting one of the capacitors. It could also be that oscillator, although it looks like it is in charge of commanding the integrated circuit on the right, which, if my intuition does not fail, is the sound card.

Upon visual inspection, do you see any swollen or oxidized capacitors?

Hello buddy, thanks for replying. At first glance, I don't see any swollen or rusted parts. By the way, I forgot to mention that the chipset fan broke down recently, sometimes it works if you touch the connection to the motherboard, but I made sure to put another one and the PCH temperature doesn't go above 45 degrees, besides the fact that it doesn't give me any high temperature warning, so it won't shut down because of the southbridge chipset since I even changed the thermal paste U_U I'm attaching two photos... although the quality is poor... https://subefotos.com/ver/?67db5e7aaeb33eba39dbc9e02a596375o.jpg#codigos

Wow this is incredible, I was sitting here, 3 meters from the pc, and suddenly.. BOOM it turns on by itself, without having given it heat or anything at all, it lasted 20 minutes on and then it went to hell again... the curious thing is that if it starts up and I turn it off, then I press the button and it's able to start up, the problem is when it turns off by itself and then I press the button to turn it on, and it does nothing at all.... but the fact that it turns on by itself without having given it heat or anything... left me completely baffled... besides, I just tested the power supply with a bridge connected to the bluray drive and nothing at all, it's been working for over half an hour as if nothing were wrong, so I doubt the PSU... it has me completely baffled already U_U

If it is a widespread problem as you mention, it must be a problem with the board. And if the solution is to apply heat or be in a certain previous state (that it is on), the capacitors continue to win as the provocateurs of the problem. Here the difficulty is in finding the faulty component. The only thing we know is that it is located near the battery.

Yes, friend, it may be the Patsburg chipset, maybe the solder has been messed up and that's why it starts up when you heat it up... the thing is that I have another motherboard exactly the same, with the chipset intact... but of course, let's see who the smart one is that does that without frying the chipset or the motherboard U_U

If it no longer has a warranty, as a last resort I would put it in the oven as we did with the graphics cards when they started having soldering problems. 10 minutes at 190ºC and ready to go

Are you completely sure it's not the source?
I would check everything again before doing things that can't be undone.
In the event that it is, as they rightly point out, a capacitor, I would suggest patching it up by hand.

+1, it looks like it's definitely a problem with poor tin soldering that has cracked.

On the other hand, what a piece of crap quality asus offers if a motherboard of this quality has these problems in 4 years... and on top of that, widespread.

I already told you, man, this is incredible, 4 years and the motherboards are failing, even much earlier... the thing is that the one who had it before 2 years could even consider himself "lucky"... at least he had the warranty as a lifeline...U_U anyway I'll make sure 100% that the power supply works properly, I'll try with another.

I don't think it's a matter of capacitors. That went down in history a long time ago. The oven thing seems like an option but make sure of the source because you could blow it completely.

yep, I just tested the power supply with another one and it does exactly the same thing. First it doesn't start, if I give it heat, it starts, that's the thing.
