cleaning camera

[snapsnap]

Hi when i take a picture of a white wall i see dirt in my picture. One looks like a small hair shape thing and the others are 2 dots. The camera is a few months old.

How would i go about cleaning this. I have changed lens so it is not that i have also done a camera self clean but that also did nothing. I have also tried a rocket blower but still no good.

Please help

Thanks In Advance

keep an eye out for a camera show - LCE recently had one in my area, and both Nikon & canon were there offering free cleaning.
