HELP PLEASE: BSOD 0x00000050 page fault in non paged area

I really could do with some urgent help.
I hope i'm posting in the right section...apologies if i'm not

My laptop keeps shutting down when i turn it on. I've windows xp pro on a fuji siemns amilo and i'm unable to get it to load in safe mode or anything...no matter what i try it justs shuts down. To make matters worse i can't find my xp cd to try and see if i can boot it off it. It goes as far as the screen with the logo for a while and then shuts down and its the same in any mode

I really would like to fix this problem as i'm self employed all my documents etc are on it and not backed up anywhere (lesson learnt - i know for the future!)

I'm not a techie but am willing to listen and try anything to fix this so any suggestions welcome

(In case you're wondering i'm accessing the net on a friends comp)
PLEASE HELP

does it shut down or restart? it is crucial to know if it's one or the other.

 

it restarts.
the only way i got to see the bsod message was to disable restart on system failure using the f8 menu
