Digital BW, The Print

Hello All,

Are there any D100 users here?  I have had one for ~2 months now, and 
was happy for a while. But, all of a sudden, the images I capture 
have nasty noise in them. First I thought it was only during long 
exposure, but in reality it is happeneing in all exposures. All shot 
at ISO 200, NEF, converted with NC 3. Anyone else seen this? I think 
this puppy needs to be sent back to Nikon for repairs/replcament.

Thank you.
