When I started up computer today I got a message that says files that are required for windows to run properly have been replaced by unrecognized versions. To maintain system stability windows must restore the original versions of these files. Insert windows XP cd. The problem is that when I purchased computer they didn't give me the cd. Any one with any ideas? I can be emailed at dferdik@aol.com.

you can contact your computers' manufacturer & buy a recovery cd.
