Anyone know what could cause sound/audio choppyness and lag? Whenever I start music or a video the task manager shows the CPU usage jumping to 70-98%. Its never done that before, and not sure what else to do. I've ran countless virus and spyware scans, I've defragged my computer, I've ran disk cleanup along with error checking, I've deleted some programs that take up alot of space, and I even went into msconfig and stopped some services and startup programs. Now my computer is acting fast as hell but when I start playing a video or music the CPU usage still jumps up. Any chance someone could help me figure this out?
