I have a fairly new montior, it is not a flat screen its pretty big, its a 19". I had xp installed on my computer and it worked fine. I got a new hard drive and installed it, then put windows 2k on it and now the screen has like a fairly light greenish brown spot that just runs slowly down the right hand side of the screen, like it is refreshing wierd. please help. I also tried playing a game and it looks like its vibrating to the right and left. I tried changing the refresh rate and it didnt do anything, and reinstalling my graphics drivers.
