I can't remember when exactly it started, but probably about a month ago or so, whenever my computer plays music it acts as if it's a skipping CD. Sometimes the music will just get garbly to the point where it's just not even possible to play music on my computer any more. At first I thought my speakers might be crappy, but I've gone through three sets of speakers and the problem ensues, so I'm thinking it must be my media players or something in my computer. Problem is, I'm totally lost when it comes to these kinds of things, so I was wondering if any of you could help me solve this dilemma? Is there anything I need to check or anything that would need to be fixed? It seems to work for all types of music I play (whether it be Mp3, or a PSF or what-have-you), on any type of media player, though videos work fine. Does anyone have a clue what could be wrong here?

Sorry for the long-winded post, but I do want to be able to listen to music on my computer without it messing up all the time.

Edit: It seems YouTube videos also have this issue sometimes.
