My windows 7 says "windows failed to start"

[mosiabuliybe]

I a very new to all this so accept my apologies in advance if Im not doing this right. But Im in over my head.I have a DELL inspiron 5010 laptop with windows 7 home premium and intel i3 processor. A week ago, all of a sudden, when I powered on my laptop, it gave the message "windows failed to start" and asked me to "repair windows (recommended)". When I selected that option, it tried to repair windows and could not do so. I called DELL customer support and they ran diagnostic tests which the system said "all tests passed". STILL the Representative told me I had a hard drive corruption and need to replace it. MY computer is hardly 16 months old. But its already out of warranty so DELL wont replace ANYTHING!!!!
Now, I just want to know two things:
1) is there a way to fix this problem and how?
2) how do I save my files if I need to freshly re-install the OS??
I HAVE to SAVE my files. Any help in this matter will be greatly appreciated.
Thanks
