Where does the light stay on? Or does it go through them all?

Might want to try the integrated graphics as well to mitigate any PCIe / graphics card issues.

Essayez-les si vous ne l'avez pas déjà fait:
Redémarrez les câbles et GPU
Retirez tous les lecteurs et la RAM sauf 1 bâton - essayé tous les emplacements et les différents bâtons
Un autre slot PCI-e pour le GPU

si vous avez fait tout ce qui précède, la dernière option est peut-être de le mettre à la planche, de tout sortir et de courir sur un banc de test/en dehors du cas

Il n'y a aucune raison pour que cela ne fonctionne pas après une mise à jour du BIOS si vous avez réussi à le démarrer avec succès et à modifier l'option de démarrage sécurisé dans le BIOS, mais la mort aléatoire de H/W se produit et cela pourrait être une coïncidence, bien que je ne sois pas sûr que ce soit le cas pour l'instant.

Savez-vous si la carte mère a une écriture du BIOS, vous pouvez mettre à jour le BIOS avec une clé USB et sans CPU, ce qui est pratique pour les utilisateurs qui ont acheté des cartes mères AM4 qui ne prenaient pas en charge les nouveaux CPU Ryzen, vous pouvez également essayer cela et voir si vous pouvez rétablir le BIOS

Sur la page GB de votre carte, il est qu'il a un double BIOS, vous ne sauvez pas comment cette fonctionne sur les cartes mères, est-ce la semaine a choisi que le GPU par lequel vous actionnez un commutateur pour passer de 1 BIOS à l'autre?

I tried the first steps but nothing, I don't know how to switch to the other bios and how to update the bios in cpu and having a black screen?

No pci isue I try with different card and different port but same problem

Sometimes buying a new Cable could also work. It sounds like the hand off is proper if the MB is running through all the lights and then shutting off, that should mean that everything checked out. What spec are your cables?

Base câble modular from evga, I have this problem after bios update and I activé thé secure boot after reload my pc go blackscreen

Surely would boot with one stick if that was the case and OP said they have tried single stick/different slots, from what I comprehend anyway

No , because I am bios version f64 before update to f65 and with f64 everything right

any way to get it to change BIOS?

I have asked the same question, on some boards there maybe a switch on others it should change to 2nd BIOS if the 1st has an issue/doesn't boot etc, haven't found any info regarding OP's board and specifically how the dual bios works, found the manual lso https://www.manua.ls/gigabyte/x470-aorus-ultra-gaming/manual?p=4 maybe something in that, upon quick inspection it shows M_BIOS and B_BIOS though I see no BIOS switch

I searching too but nothing about this information

You have unplug everything except GPU and tried all RAM 1 stick at a time in all slots?

 

[chumlee]

Apparently the dual boot active after 5 try booting if detect à fail , but for me nothing happens

Yes but nothing

 

[Marcus L]

Do you have another system/friend/family member you can test out the parts? at this stage something may be broken and my main suspect would be the board which I am thinking is not in warranty as it's quite an old board now (warranty wise anyway)

 

[chumlee]

It's weird because my PC turns on normally as if nothing had happened but I have a black screen and it does a little one every 10-15s as it reboots each time, and as I said I have neither my keyboard nor my mouse which are powered strangely.


Yeah it's totale Old, I buy this in 2018-2019 I mean , no my fried dont play on pc or they have pc portable or mac, did you have a motherboard recommanded for my composant , and not too expensive can I buy . I sûre the problem come thé motherboard

The circled part indicates you have two physical bioses. M_ probably means main, and B_ probably backup. I reviewed the manual and I found no details on switching between them. You may have to reach out to gigabyte support for that answer (could be a jumper somewhere).

The arrow shows 4 LED's that are more for diagnosing POST errors. Please tell us the status of those LED's.

I say for the LED cpu vrai and boot, she blinks each in turn I not see nothing tout for active thé dual boot

Swap GPU to different one (Nv card 20-series or older) or legacy AMD one (GCN), alternatively borrow APU from someone and unplug Vega card.
Go to BIOS and enable CSM (leave it in EFI mode for booting/storage devices).

Alternative if this doesn't work is to force disable 4G decoding and ReBAR support.

IF everything else fails, there IS a slight chance picture on screen will eventually come up (within 5-10 minutes), assuming OS boot sequence still works. ^This only works if Windows has issues and tries to reinstall GPU driver (you can try unplugging and connecting again monitor cable [DP/HDMI], to force monitor detection - as unlikely to work as it may be...). If you already had drivers installed, you should see Windows desktop (regardless of EFI/CSM mode in BIOS, and again assuming windows booting works as intended).

I tried with another nvidia card but still a black screen, I have no access to my bios at all

RTX 30/40 ?

Omggggg boys a got it !!!! I got itttt!!!

I again tried boot my pc and I got the fckin bios

Side note :
Updating BIOS on enabled Secure Boot might "nuke" your boot OS, unless you have security keys saved somewhere (that thing with CrowdStrike).
Also, don't do Ultra Fast boot or hibernation "shut down" - it's a real pain to deal with, when they fail to shut down PC correctly (those things skip POST step and go straight to Windows, under usual Fast Boot - you should be able to setup time (in seconds) how long POST screen is meant to be shown).
I assume you have NVMe OS drive (and Windows 10) ?

 

[chumlee]

Note latérale:
La mise à jour du BIOS sur Secure Boot activé peut "nuquer" votre OS de démarrage, sauf si vous avez des clés de sécurité enregistrées quelque part (cette chose avec CrowdStrike).
Aussi, ne pas faire Ultra Fast démarrage ou hibernation "shut down" - il est une vraie douleur à traiter, quand ils ne parviennent pas à arrêter le PC correctement (ces choses sautent POST étape et aller directement à Windows, sous Fast Boot habituel - vous devriez être en mesure de configurer le temps (en secondes) combien de temps l'écran POST est destiné à être affiché).
Je suppose que vous avez un lecteur NVMe OS (et Windows 10) ?

Yes i don't update the bios with secure boot , i active the secure boot after the update , the fast boot it's always disabled, i have one nvme and my OS it's w10

Funny thing I notice that I went back to the f64a version of my bios while I was in f65

OK after reboot my pc return same problem ....

still black screens but I can return to the bios menu despite everything

The latest is F65b and the one before F64

I assume F65b is a beta, so maybe stick with F64?
