ChaoticPaladin

The 675m in my m18x r2 died, and I was reading about upgrading to the 780m. I already have the card installed, but even after following the general suggestions, I can't get the drivers to install. I downloaded a modded INF, and it recognizes the card, but fails to install with no error. So a couple questions, I noticed some people said they flashed the bios to an unlocked version, is that required to make it work? And just for reference, will there be any issue with updating the drivers later?
