Help, I have an ongoing issue, that I just can't figure out. I have Windows XP Pro with media player 9 on it and I cannot play video files. When I try to play them, sometimes they will work, but other times the whole computer will freeze and I have to hard boot the computer. I have an AMD 2000+, GeForce 4 Ti4400, 512MB ram. I have a good enough system to play the files, but just can't. I have also tried different players and also killing all the processes that I can in the background. Nothing helps! Help!
