Have a 6-month old Dell Dimension 8300 running Win XP Home. All working well until last week when we decided to download SP2. Sometime during that download not sure what occurred. Since then a 'Windows-corrupt file' message keeps appearing and won't go away. The file is called "c:\$MFT". Searches have not found this file. Nothing seems to get rid of it. Anyone else have this happen? PLEASE HELP!!!!
