My sister's computer is in bad shape. I printed a doc for class and it was mirror image! The C drive is 99% full, and that makes no sense. When I tried to use the DDS app it came up as gibberish in the text file. Xp is updated, nothing illegal going on. Re-installing Xp is not an option because of some legal land-surveying software that is quite expensive to license would be lost and cannot be replaced. Also, there are about 7 years of pictures on the computer. How should I tackle this?
