I'm having some weird issues with my card as well.....
(Display driver stopped responding and has recovered Display driver NVIDIA Windows Kernel Mode Driver)
I was wondering if the new bios can be applied to my card which is slightly different from the OP's. I am currently running the GV-N560SO-1GI-950 in SLI. Also one other question, would I need to remove one card, flash the bios, switch the cards and repeat the process ,then add the 2nd card back in and resume my SLI setup?
Thank you in advance.
Frustrated User.
**UPDATE**
I just tried to use the @BIOS tool from Gigabyte but it said that the "BIOS id does not match" ...... sigh
