Macbook Pro Vista, Sound skipping like CD when listening to Music

[digiegg]

I just got my motherboard on my MBP because I had the black screen problem due to the graphics card. Now I have problems w/ my sound.
It keeps skipping after once in awhile for some reason. I installed the latest Realtek sound drivers. This happened with the original driver too.
It plays music fine but every minute, it skips like a bad CD player.
What's going on here?
