When I try and play my CDs on my DVD/CD RW on my PC I hear a background continous dim background thumping as if you're in a car running over those bumps embedded in white lines on the side of the highway. I have updated sound drivers with no different. How do I fix this and will it appear on my ipod when I buy one (the plan)

The thing is the dvd drive can burn 4GB dvds of data which is usually the test the drive is working properly.

And it makes this dim thumping on many different CDs
