A few days ago I had to move my old laptop and I noticed the battery was still in it so I tried to turn it on and the hard-drive actually started spinning. It gave me a startup error, but after a few restarts it gave me the boot options and i set all to default and selected the hard-drive as the boot location and it turned on.
Now we have two computers for business and one is XP and the other Windows 7, all our missing files are recovered, and all the programs that don't work on 7 can now be used on the XP.
