No Problem.

You need a bootable USB Stick with Nvflash and the Vbios.

Please rename the Vbios to a easy Name like GTX680M.rom

You start from USB Stick in Legacy Mode with the Stick in a USB2.0.

Then You type:

 

nvflash -4 -5 -6 GTX680M.rom

 

Then You confirm all and it will flash the Vbios.

After this You restart.

 

nvflash_5.163.zip

 

First step: You need a bootable USB Stick with Nvflash and the Vbios -> DONE
Second step: Please rename the Vbios to a easy Name like GTX680M.rom -> DONE

Third step (can't understand): You start from USB Stick in Legacy Mode with the Stick in a USB2.0 -> should I power off and boot my notebook on USB? How to perform this step that you wrote me, I supose that's the flashing part? Can you tell me in detail, please :) I'm sorry to bore you, but I really need help to save my notebook :)

You need a USB Stick from where You can starting from like HD.

You can make it bootable with the Tool Rufus.

Then You extract nvflash and the Vbios to the USB Stick.

The Boot Mode in Bios must stand on Legacy,this You can find in the Bios under Boot.

Then You start from USB,if it will done You type:

 

nvflash -4 -5 -6 GTX680M.rom  

 

and push Enter.

Then You must confirm the Flash and nvflash will flash the Vbios.

When this is done You start new and change the Boot Mode to the old Value.

One last question and I won't bother you anymore:

(factory) DELL GTX680M is a 2GB model GPU, (factory) MSI GTX680M is a 4GB model GPU. And we are talking about flashing with UNVERIFIED (or modified) 2GB MSI vBIOS (knowing that factory MSI is s 4GB model)? Don't you think this can cause problems and brick my GPU? Do you think it will work?

Look what says at techpowerup.com (link above):

Warning: You are viewing an unverified BIOS file.

This upload has not been verified by us in any way (like we do for the entries listed under the 'AMD', 'ATI' and 'NVIDIA' sections).
Please exercise caution when flashing it to your graphics card, and always have a backup.


Thank you very much for your help. You're very kind :):):)
