Documents and files are missing after turning on pc



I have a problem that my documents and files are missing after I on my pc.
I have saved my word document in my document and i make a copy on desktop
after that I shutdown my pc and start it again and the files were missing on both desktop and my document .

I have a windows XP pro.
anybody know how to solve this problem?
it happen frequently…


Maybe it’s time to start backing-up your HDD’s…Just a thought, since it “happens frequently”, and you do consider your docs important, right?..
