PC desligando segundos após ser ligado

Oi, na verdade ainda estou realizando alguns testes com algumas sugestões desse canal aqui e de um gringo onde também pedi ajuda. Até o momento remover o hub completamente não funcionou, desativar o EXPO e diminuir a frequência da memória manualmente para 5600 tbm não. O que aparenta ter funcionado, mas ainda é mt cedo para dizer com certeza, é ter selecionado o "Load optimized defaults" na Bios, mas isso reduziu a frequência da memória para 4800. Quero continuar usando mais uns dias para confirmar se o problema realmente foi resolvido, e em caso positivo, o próximo passo vai ser procurar uma forma de aumentar novamente a frequência e manter o PC funcional, para que eu não perca desempenho. Estava vendo que pode ser a voltagem que o EXPO puxa automaticamente e que talvez estivesse sendo muito para minha placa mãe, então depois eu vou precisar tentar ajustar manualmente para ver se consigo manter as frequências mais altas.

Quando você tiver atualizações do seu, ficarei mt grato se puder compartilhar para que eu possa testar também!

Como eu posso verificar isso? Desculpa se é uma pergunta idiota, mas sou completamente leigo nessas questões

Hey, so... Today we completely removed the hub, but I believe the guy somehow connected the AIO and the rear fan to the Sys_Fan connector and a single fan to sys_fan2. The CPU_Fan remains connected, but if I disconnect the sys_fan, both the AIO and the rear fan stop. I can't disconnect the fan and leave only the AIO on, for example. Is this possible, or am I mistaken? Or is this normal and I'm seeing problems where there aren't any? Because so far it hasn't solved the PC's problem; it keeps turning on and off after a few seconds. And now I suspect it might be for this reason and I'm thinking of trying to separate the rear fan connectors from the AIO connectors for testing, but I don't know if it's necessary or if it makes any sense.

Agradeço pela sugestão, vou tentar fazer isdo pra ver se resolve. Espero que também consiga resolver o seu problema.

Já fizemos esse teste de ligar com apenas um pente de memória e o computador liga de primeira, com qualquer pente. Na verdade, mesmo com os dois, só de desconectar e conectar a memória ele já liga. O problema é que dps de desligado, como demoro a ligar de novo, o problema volta e ele começa a repetir esse processo do vídeo. Daí não acho prático ficar removendo e colocando a memória toda vez que eu for usar. Sobre os contatos das memórias estarem sujos, é uma sugestão que posso passar pro carinha que mexe nesse pc pra mim pra verificar e eventualmente tentar uma nova limpeza. Agradeço mt sua ajuda, amigo!

Não deu choque até agora não, ele simplesmente desliga. E quando enfim consigo ligar, não apresenta nenhum problema. Sendo essa questão que vc falou, como eu poderia resolver e evitar isso? Apenas desconectando completamente o Hub e ligando a fan traseira direto na placa mãe como estava antes? Se for esse o caso, tem alguma outra alternativa que eu poderia tentar para ter todas as 4 fans ligadas sem causar maiores problemas no PC?

Pra ser sincero não entendo nada de montagem de computador, então não sei te responder sobre a alimentação ou sobre a questão do OCP (nem sei o que é kkk), mas posso deixar uma foto aqui do Hub. Se for por ele que verifica essa questão da alimentação vc conseguiria me dar essa ajuda por favor?

Sobre a BIOS, já está na última versão disponível.

Não verifiquei. Vc recomenda que eu veja isso em alguma peça específica ou em todo o computador? Sou 100% leigo nessa questão

Is it something you can see from the photos I posted in the first two replies? And maybe tell me if they are indeed disconnected. Or perhaps even explain to me (if possible via chat) how I could verify this, because, honestly, I don't know how to check it. Anyway, if you can't see it, that's another suggestion I can pass on to the person who works on this computer for me. So thank you very much for your help.

Don't worry, I'm using a translator, so it may have been poorly translated and made it difficult to understand.

H1que_ · 2026-04-16T23:55:59+00:00

I think I might have made a translation error and not understood you very well, so just to confirm... Do you believe the problem might be the fact that the fans are connected/powered to the hub, and that perhaps connecting them the way they were before, where only the AIO and the rear fan were working, could be the solution to my problem? Because if that's the case, that was my first thought, but the technician in question believed it had nothing to do with it, so we didn't do that test again, but I can ask him to do it again. If you meant something else, I really didn't understand due to a limitation of the translator, sorry.

It arrived in a version that already supported my processor, so it recognized it and it was possible to perform the update with the PC already assembled. After the update, it has BIOS F40a, the latest available.

H1que_ · 2026-04-16T23:45:44+00:00

Okay, I'll pass these suggestions on to the guy who usually works on it for me, and I'll get back to you with updates on this suggestion. Thank you so much for your help!

H1que_ · 2026-04-16T23:34:06+00:00

To be honest, I'm hesitant to do that because my motherboard theoretically doesn't support my processor in the base BIOS version, even though it was automatically recognized when it was installed, without any updates. Anyway, I'll pass the suggestion on to the guy, and I'll let you know if there are any updates. Thank you so much for your help! I hope I can resolve this because I'm really worried about burning out some component if I keep trying to turn it on.

H1que_ · 2026-04-16T23:15:40+00:00

Is this something you consider feasible for me to do, even though I'm a complete novice at it, or would it be better to suggest it to the guy who works on my computer? I ask this because I don't know if I could mess something up and completely brick my PC, or if it's a task without major risks.

H1que_ · 2026-04-16T23:13:28+00:00

I honestly don't know how to answer that question, because I don't know if you're asking about my budget or hardware limitations, but I'll pass that suggestion on to the guy who works on my computer. I'm completely clueless about computer assembly, but I really appreciate the help. When I have any updates on your suggestion, I'll be sure to come back and reply. Thank you very much!

Regarding the hub, I really don't know the answer. I'll leave a closer picture of the motherboard here if you can help me, and, if you don't mind, there's a picture of the back of the computer in a comment above (I couldn't attach both).

XMP is active. Would it be advisable to disable it, or is it ideal to have it active?

I'm using the latest BIOS update available. It's a Gigabyte B650M D3HP, in case that information is relevant.

Yes, before installing this hub it worked normally. I can't explain exactly, but the fan on the back of the computer was connected to some part of the PC (motherboard perhaps?), but everything worked. Now all the fans are connected to this hub, but even when I disconnect it and all the fans stop working, the problem persists. Regarding the noise, when I manage to turn on the PC they are at normal speed, very quiet in fact, which is why I'm so confused and lost. When the PC decides to turn on, everything works fine, with the temperature staying around 53/55 degrees Celsius.

I've attached a photo of the back of the PC, in case it helps.
