Bonjour,

Suite à la mise à jour de la carte mère MSI MPG Z490 Gaming Plus sur le pc de mon fils avec l'application dragon center, l'ordinateur démare et l'écran reste noir.
Le pc démarre et les ventilateurs s'allument et la led EZ débug CPU est allumée en blanc.
J'ai tenté de réinitialiser le bios avec JBAT1, en faisant contact avec un tournevis, car je n'ai pas de cavalier, mais l'écran reste toujours noir.
Je précise que l'ordinateur fonctionnait parfaitement avant les mises à jour, je les ai faites pour passer à Windows 11.
Par avance merci pour votre aide
 
If you look here, you only need to connect eight of the ten pins. See if you can "de-pin" the individual cables from the clamp. Then you might be able to put them onto the appropriate pins of JTPM1. If not, or if they don't fit, you would need 2.54mm (programmer) to 2.00mm (JTPM1 header) cables.

Only now do I see that there's special "MSI kits" with a cable that is correctly wired for the JTPM1 header:

But with the diagrams you can find in the link from above, comparing with how your clamp is wired, it's not too difficult to make this yourself from individual wires.

Once you got this wired up properly (you should see once you try to read from the BIOS chip), then you're a good step closer to success.

i need to be sure, because i can't detect the bios ship. I don't know if It's because of the clamp or because i don't have the correct name of the ship. Where can I find the exact name of the bios ship on my motherboard?
thanks
 
Here's a picture of the BIOS chip.

I typed each of the instructions into the coding program, but it doesn't match any of the models listed in the program. I'm using CH341A Programmer; should I be using a different one?
Thanks again.

Good news.
With CH34a1 programmer i can speak with the chip but i can't find the good one...
I download a programer, i find the exact name of the ship, but i can’t talk to her.

next step will be the succes
 
Glad we could solve it!

With "wood settings", it was probably a mistranslation of "board settings", as in, BIOS settings? Press the DEL key after power-on or reboot, like most boards.
