So recently, for whatever reason I am getting this really weird stuttering issue in Windows, whether it's playing a game, video file or just generally browsing, I get this stuttering. Also when I open taskmanager, I'm getting 30% CPU usage even though none of the programs listed are using the CPU.

COD

Both the sound and the video stutters, and this happens in Windows also.

Taskmanager

Oblivion stuttering sound

Anyone have any ideas on what could be causing this?
