I just recently reinstalled windows on my computer to try and fix a choppy media problem i was having. Everything was working after the install until a few days ago when it started doing it again. It doesnt matter what i use to play the music and videos. I have 756mb of ram and running windows xp pro. I use itunes to play music (on the previous install used windows media player) and for videos i use windows media player. The problem first started up again about 2 weeks after the fresh install. I was able to fix it by doing a system restore but a week later it happened again. I did the restore again and it worked for about another week. Now the problem is back again but the system restore does not work.
