Over the last week or so almost everytime I turn on my computer it starts to do a check for disk consistency. It goes always to step 3 and freezes, nothing happens. I then have to reset (pushing the restart button doesn't work) my computer and press a key to cancel the check. I have a NTSF file system on Win XP with SP2. I don't know what to do. I read a thread in this forum ( here ) I tried check the registry, but the first two things to check I couldn't find, then the third was as it should be. Please any suggestions welcome.
