My computer is having trouble playing any type of media files. When it attempts to play music or videos through either windows media player or itunes the music begins to slow. When I have the task manager open in the processes section I can see that the CPU count is up to 30, sometimes it goes has high as 60. This problem also occurs when trying to play videos through youtube, both through firefox and InternetExplorer. I have no idea what could be causing this.
For a while there Windows Media Player seemed to be sucking up all my RAM when I tried to play music, at the moment, its just sitting on, not playing anything and it's Memory Usage is 154,440 KB. When i wanted to listen to music or that i would just use iTunes instead but now it seems the same thing is happening to it aswell.
I have no idea what it could be, maybe a codec or something. Please help
