Rename "XFX 680i LT_680iLT_721N9P07.BIN_Slic" from the .rar to "721N9P07.BIN" before flashing. You're right that it's a good idea to get the nforce drivers from Nvidia since they will be the most up to date. That's a separate issue from the BIOS though.
Thanks. The BIOS did go from P06 to P07. I wasn't talking about Nvidia drivers. XFX's tech support told me that they make some of their BIOS updates and Nvidia makes some of the BIOS updates. It didn't sound kosher to me, but oh well.
I rewrote the BIOS, then I rebooted, but, nothing can't be seen on my monitor. Even BIOS mode won't start. Afterword, I moved the jumper pin to boot the recovery mode and rewrote the Bios again forcibly. So the computer revived.
