Hi,

during a normal reboot my Mac Book Pro suddenly doesn´t boot.

 

 

Only short run on each fans, light in front light up for aprox. 4 seconds and it shuts down.

 

 

If I hold down the power button the light starts fast blinking for aprox 16 times and it shuts down.

 

 

Taking out all RAM it goes into a loop and a system sound - sounds really like a failure sounds every 6 second until I press the power button again for 8 - 10 seconds / same as hardware reboot or shut off the machine.

 

 

It seems like the machine has problem booting from ROM - yes, but what do I do with that?

 

 

Thanks,

Kasper
