I have had my Acer Aspire 6930 for about two months and can't fiqure out whats wrong. Was working the other morning and got hung up on internet later in the day. Tried to shut it down and restart, started laoding and after an hour and a half nothing. Shut down and restarted again and got message saying it was missing file CLFS.SYS Tried running recovery discs (three times) and still the same thing. Any help to fix the problem would be greatly appreciated. Was reading it might be vista autodownloader related?
