|Do you have a manual for the computer? Most OEM computers that come with Windows pre-installed have a hidden partition on the hard drive that contains all the files needed to restore the computer to the factory state. |
Your manual should explain how to perform that restore. The procedure usually involves certain keystrokes at start up.
If you have person data that you need to copy you will need to access the files and copy BEFORE restoring to factory state. There are two methods available to you. First one is to remove the hard drive and install as a slave on a compatible computer. If the drive itself is not the problem then you should be able to access the files for copy.
The second method is to use a live CD to access the hard drive while it is in place. Knoppix is one such live CD OS. Knoppix installs to and runs from one CDR or DVDR. You can download for free but you will need a fast internet connection and a computer that can burn an ISO CDR.
Below is a link to download Knoppix.
If using the slave drive method you will need a computer that can read NTFS file format ( 2000/XP/Vista) and you may need to take owership of the files/folder. To learn how to do that look at the second link below.
