My Computer...

I think my computer is mentally handicap just because it won't do anything with out taking an hour and then it won't let me work on the clips I try to add and that is no fun. So untill it is fixed i dont think I can do anything. I wanted to seperate the movie and work on them seperately bu there would be no way to get them back in order and match the audio and so it would almost take twice as much work instead. So anyone with useful information please let me now.
