Did you have any luck with this? I am experiencing the exact same problem (without the french accents and triangles).
I assume it is something to do with the drivers, since it conks out after the windows 7 intro screen (which uses no/basic drivers?).
You are right, might be a problem with the drivers. I've also updated the drivers but its of no use. Looked all over the web for the solutions, but didn't help. Apparently, I read that the card is on PCIE 3.0 and my mobo is on PCIE 2.0 and at times they are not compatible, so one should ask for a replacement.
I am going to the service center to ask for a solution / replacement for the same.
