I NEED HELP!!!!

My computer is a Dell Dimension 2300, with 256 mb, and 30Gb of space, i added the OSX "flyakite" recently, which resulted in a system faliure.
Now I can't access Windows, when I turn on the computer it flashes to a blue screen that says system faliure (with a bunch of letters and numbers) and no possible way to avoid it (the blue screen).
So are there any programs that will enable me to recover my files on my hard drive????

Thanks so much!!!!
