you are right, I have not lost my operating system it appears it be more serious. any ideas what it could be. when i start up it goes through xp pro start up to user accounts ok, the first you notice a difference is when i click my user and the windows intro sound is no longer played. It very quickly just shows my image screen without any desk top items or bars. it is all very quiet from the hard drive no sound at all. after a few minutes you can get the task bar to appear via ctrl alt del and browse folders. some will open the smaller programs but after a very short time the whole lot just freezes up. ive checked some folders like my pictures music and they are now empty?? and clues
