Among the PCs I own, that one is the newest one and the others won't accept such a new card

I did a firmware update for the P7N, I read somewhere that nforce7 chipsets might have that kind of problem. Very funny to have problems with a nvidia chipset and a nivdia GPU... but whatever.

I'll update if the problem isn't solved after that.

Thanks a lot.
