PRAM and SMC reset did't help

Failing that, it is always a good tool to have in your arsenal.

Have you solved it yet? I tried the PRAM approach but it didn't work. I have the same setup and the same problem.

That leaves the Disc Warrior or Restore DVD+repair drive options mentioned by P. Did you try them already?
