No, there's no way to actually wipe the file system without getting rid of your operating system. Instead, let's make sure that's the problem before we continue with that. First upgrade to SP2: http://www.microsoft.com/downloads/d...displaylang=en
If that doesn't help then we can test the file system. Open an elevated command prompt (Start
>right-click>Run as administrator
) and run the command chkdsk /r/ f
. It may take 2-3 hours to complete, so you can leave it running unattended.
Good luck to you. Let us know how it works out.
