restoring my hard drive?

for some reason my labtop doesnt goes into windows xp, when i
turn the power on there is the fujitsu logo and then the screen
turns blank. I called fujitsu and tried the option of using a bootup
disk and that didnt work, next im going to try going to a service
center to see if its the hardware, but if worst comes to worst,
that i need to restore my hd using driveimage and eraseing my
files, how can a get those files back????
all my work and especially soon to be due homework is on that
labtop how can i restore my files...I remeber that nothing is ever
really erased from HD....
what should i do?

i did find a software @ http://www.dtidata.com/Products_ria.asp
is that good or is there some other way i can restore my files?

i went into setup and my hd is still there, but i still cant get into windows does that mean that if i use a executable that fujitsu gave me to restore my hd to how it was when i first got my labtop then the recovery program will work?

i tried about everything there is but nothing worked to save my hd so i went to a repair shop to see if its the hardware but in the end the repair shop cleaned my harddrive and reinstalled windows.
thanks Salem for your suggestion
