I had the same problem last summer, oddly enough with..Battlefield 2 I think(but I use it just the same!)
I tried a diagnostic that scans your harddrive.
Since I have a Lenovo computer, I have this "ThinkVantage" button that if you press on startup gives you plenty of startup options.
Including diagnostic tools. (you look for any options on startup) My suggestion is to take it to Best Buy/Geek Squad or some computer repair place.
If your computer fails to start up or you get blue screens, you more than likely have lost your HDD.

Honestly,

The only thing the Freak Squad is going to do that you can't do yourself is charge you over $50.00 to tell you they can't fix it unless you buy a new H/D from them or a new Laptop.
Anything they can do, you can do yourself by asking right here.

I've lost track of how many systems I've had to fix, repair, recover due to the gross negligence of places like Best Buy, Circuit City and Office Depot.
Most of the people working there are High School and College students that know just enough to be dangerous.

Getting off my soap box now.....

S!
