Microsoft word wd not open

This is really really urgent...I have to submit reports and all the data is on my laptop as word files (unfortnately i do not have any backup and the deadline is approaching)..i was working on my toshiba satellite laptopn (windows xp home) and it recieved a blue screen error, while trying to open the word document. it said that i shoud go for a diagnostic test or check memory for faulty parts. this was followed by restart of the laptop and i restored it to an earlier restore point. None of the word files open now, though on being clicked for some time it does look like the laptop is processing, but after a while nothing happens and it just hangs. I would be really really helpful if i cd get any help in this regard...its really urgent...and yeah i also tried deleting the normal.com files, after which microsoft word opened only once and not after that
