Thanks, I posted a reply on the other topic following the link you gave me, but I think that one is on the wrong forum. Maybe a Mode could move and merge it to this one as the problem is quite similar and this is the right forum for discussing it.
EDIT:
Just did the CHKDSK but can't see the results as the windows shuts down as soon as it finished checking. Maybe if someone lets me know how to get the info from the process I could know...
