How do i fix my toshiba labtop it says directory /$secure is currupt or unreadable please run chkdsk utility?

It actually sounds like you may have had someone hack your computer. I would backup personal information somewhere else and then delete it of of your computer and take your computer to a shop immediately. This could be a false alarm and your computer is just messed up code wise. Look for that utility because it will help you. I recommend that you google the name of what you need.( utility)
