[SOLVED] problems after CPU update E7400 -> Q9400

Hello,

My SIERRA was working pretty well with Core2Duo E7400 processor (with latest BIOS available).
I just bought a used one, Quadcore Q9400 but this don't boot. Its stops after Apple logo, I see a forbidden logo... nothing more happens...

I saw that my Mobo is fully supporting this CPU with latest BIOS I already have. I have also another SIERRA hack, my other computer has Q6600 so I know quadcore is supported too.

Maybe anyone could help me?
Must I re install or only clover changes?...
