pc does not start anything

[rafaziel]

Hello, I have an Asus Rampage IV Extreme along with an Intel I7 3930 K. It was working pretty well, the PC is about 4 years old. One day I went to turn it on and suddenly nothing started up, not even the fans. The thing is that if it gets power from the power supply since the "power" and "reset" buttons and the light that indicates which of the two BIOS you have installed turn on. I have checked everything, and everything is in order, I think it's the motherboard, because I have looked at more forums and other things and I saw that if you gave heat to the CMOS battery area it would start... well, I ventured to give it some heat with a hair dryer, and the truth is that it worked... the thing is that the people who did it started up and stayed on without any problems... the thing is that it starts up for me, but it lasts on for about 5 - 10 minutes at most. It's not a temperature problem, because when I have managed to turn it on I have been monitoring both the CPU temperature and the motherboard temperature, as well as the southbridge chipset, and they are in optimal conditions. Do you have any idea what this could be? having to start it up by giving it some heat is not normal... but that after managing to start it up it is not stable is what worries me the most... the people who start it up this way the only problem they have after is that if you turn it off and it goes more than 8 hours without turning on they have to give it some heat with the hair dryer again, but they last on without problems. Another thing I have noticed is that if before it turns off on its own, I turn it off myself, then I press the start button and it goes without problems... when it no longer turns on is if it turns off by itself... Any suggestions?... thanks in advance

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.

[rafaziel]

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.
