occasional noise from right lower corner

[huskers]

My T43 is one month old. I am hearing a strange sound from the right side of my laptop. The sound occurs once in a while. It lasts for a second and goes away. I couldn't figure out whether it is coming from hard disk or optical drive. I ran PC Doctor hard drive test succesfully. Can anyone tell what that sound may be.

Lower right (under the palm rest) is where the hard drive lives.

Can you be more specific than just 'strange sound?'

Its like a creeking sound. I am unable to locate the exact location whether it is from hard drive or optical drive but it is coming from the right side.
