Laptop Booting problem

[Tarkin]

Hi

I have a Toshiba Portege S100 Centrino P-m 740 1.73 Ghz / 512mb 60gb Dvd/cd-rw Wlan 14.1-tft Xga Wxp Pro Uk

A couple of days ago, while XP was just loaded, I switched off (hard reset) the laptop by mistake. I somehow must have done something wrong as I cannot get back to a normal XP session.

I am faced with this constant loop:

Laptop starts>boot sequence>Win XP logo appears>Blue Screen of Death>Laptop re-starts>...and so on.

The Blue Screen appears very briefly so I do not get sufficient time to read the message.

This happens in every configuration I try (safe mode, last known good configuration, etc.)

As usual with these sorts of things, I did not back-up my data and I am desperate to preserve the data on the hard disk!

Any help would be most appreciated

Thanks
