Dead Bios??

Hi, I downloaded the bios update for the nc6120 direct from the hp website, ran the update and i got the blue screen of death. it is a stop screen apparently, it says try to disable to bios shadowing or cacheing??
I cannot get into safe mode as it goes straight to the stop screen.
I have tried reverting to last known good config. but that does not work either.
i can get no further than that i'm afraid. have i killed it or is there life after Mike?


Hope you can help,
Mike
