DO you have a CD burner? CDR or CDRW drive? IF so try burning your data onto a Cd.
IF not, you could always save the files in compressed form ZIP, RAR, ACE etc...
and email them to yourself, use an online email service like hotmail or yahoo. Keep the files in your folders until you get your PC back and then reinstall them.
Hope that helps,
Don't give up, get your PC exchanged, reinstall your info and you'll be back in business in no time.
For future reference you might want to look at another company that does in home repair when you buy your next PC. It is a service worth its weight in gold!
