Ok got problem now. I try to update my gtx 1080 ftw on my first bios. I run the file, everything pass in this black window i so go restart computer to be sure than everything is alright. Now i can`t log in to windows with primary bios. Now i am using secondary bios.
There is any way to update primary bios again but from secondary bios?
This is Exactly what happened to Me !!
I tried to run the flash program and it didnt work right. It changes your resolution when it disables the GPU to do the flash and then its supposed to change the resolution back to normal. But the first time I ran the flash it didnt do that.
Instead it said it was finished and I tried to restart my PC but when I restarted I got a totally BLACK SCREEN. I was on the Master switch so I shut everything down and switched to the Slave / Secondary and then I got into windows ok. The secondary slave has the Old BIOS.
And then I shut down the PC and I switched back to master and it loaded up but the new BIOS were NOT on my card. I check in the system information. It somehow reverted back to the Old BIOS on my Master.
So then tried to run the flash in safe mode and the Flash took to the card but I am still getting Black Screens. The news BIOS is on my master now but when I try and reboot my PC i get to a Black Screen.
You can try to go back to master and see if it did the same thing it did to me. It might load up on Master showing the old BIOS.
You check the bios by going to Nvidia control panel / view / system information.
