Ok, whenever I try to watch music videos or listen to audio music, it keeps on skipping frames and sounds. Yesterday, I tried to listen to Megadeth's Hangar 18 and it ruined the entire solo. The day before that, I was listening to Slayer's Raining Blood and the thing skipped like 5 lines of lyrics and then a whole solo. I'm on Windows 2000 Pro, how can I fix this?
