Q: Grey Screen MBP 15" 1,1 OSX 10.6.3

I have a MacBook Pro 15" 1,1 and now this issue:

 

I start my Mac and after the Screen with the Apple and the loading Circle it wents grey.

At this moment, the System would be fully loaded, and would show the Desktop and so on.

 

But the System hangs at this grey screen for ever.

 

Only way to get System "fully" started is the Secure Mode (Shift)

 

Things i have checked:

 

AHT: all fine

Disk: Fine

 

What i did: Fresh install of SL but it was only possible to install in Secure Mode (Shift)

 

I started in Single Mode: (Apple+S)

It shows me system is okay.

 

But below it shows. System has been modified.

 

I did PRAM reset

I did SMC reset.

 

I tried to reinstall the Firmware and the SMC but it was not possible. (Got a prompt: It is not necessary to install it)

 

 

Any Ideas?

MacBook Pro, Mac OS X (10.7.5)

    1. Turn on the computer and continue holding the Power button. The sleep LED will blink rapidly, then slowly, then rapidly (3 quick blinks, 3 slow blinks, 3 quick blinks).

    If the MBP will not enter that mode makes the case for assistance more pressing.  I have no solution for that.

     

    Note that an Apple Corporate store will not charge for an evaluation, but an AASP might since they are independent dealers.
