I had just got a new ssd on my computer and noticed it was  running on sata 1 speeds.  My mobo is a Evga 680i model # 122-CK-NF68-A1 which should run sata 2 speeds.  So I thought it might help to update the bios to the latest  which was NF68_P33.  When it rebooted after the flash it says single graphics card detected in pci e slot 2 or 3.  move it to slot 1.  It has always been in slot  2.  That is what the instructions say if using 1 GPU.  Anyways I switched it to slot one and it makes a long beep and gives error on MOBO F7, nothing displays on the monitor.  I also tried slot 3 and that is the same error as it within slot 2.  With it in slot 2 or 3 I can hit delete and get into the CMOS.  I've tried the alt + f2 to load the flash utility but the error comes up before it loads.  I know it is an old computer, just wanted to get a little more life out of it.  Thanks for the help.

Thanks for the quick reply.  That is very helpful knowing that they changed slots for single GPU, I thought for sure something went wrong with the flash, now it's more of a maybe I can get it to work now.  I tried pulling battery for a few min with power unplugged but still 7F error.  I'm trying again but I'm gonna wait 30 min or so.  Well at least now I might have some hope.

Still no luck.  Tried a few more times.  Still get the 7f fault.  I did try f1 but nothing at least nothing observable.  If I hit delete it changes to code 01, and if I press f10 (after delete) which is the cmos save and exit it will restart.  Any other ideas?

I'll look in to that. If it's more than $20 it might not be worth it though since it is so old.

You're welcome..Good deal! 
 
It's been 3 or 4 years since I put together a BIOS blind flash package for somebody..Was afraid I forgot how..Glad it worked for you.
