I am having a very odd stuttering problem with my laptop, and it just started happening recently, however, I really have no clue what is causing it. Basically whenever I play music (even when I'm not), sometimes my laptop will stutter and lag for almost one second. The frequency of it occurring is about every one or two minutes. It's very very annoying and I'm wondering if anybody else ever had this problem.

Are there any new updates to your audio driver? It was most recently updated on your computer in the fall, so If you updated it, it could help. Otherwise, reinstall the most current one.
I remember having a problem like this with Media Player Classic - home cinema, there was something wrong with my configuration of the codecs. But that was only when I was playing a video file, not with mp3's, etc.
It could be an unrelated issue, like a CPU issue. Do you experience any other abnormalities, are the temps fine?
