Hi. My computer is not responding. Well, it is but when I boot it, it sometimes freezes and when it does work it freezes at random. If you let it be when frozen on the desktop a message pops up from the tool-bar saying something like "Could not save C:/$Mft. Try saving somewhere else." It was working fine around 22:00(10 PM) GMT+1 yesterday. This problem occured this morning when I was going to check trainschedules before leaving for school. Does anyone have a idea why this happened, and how to fix it? Thanks in advance. If you need to know I wrote this from brothers PS3.
