Windows 7 includes a disk checking tool called CHKDSK which is similar to the "scandisk" tool from older versions of Windows. This application scans your hard drives for errors such as lost sectors, bad sectors and corruption.[/quote

Since your power went out suddenly your PC might have some corruption issues, I'm guessing you're using Win7 so have a look at this guide.
