Do you know the history of the DV 400 board, i.e. Why did it become available, could it have been intermittent with its last owner, is that why it became available? Do you know how the boards last owner handled it, did they take anti static precautions, if shipped to you was it in an anti static bag, did you take anti static precautions when handling it? All things to consider if its now defective. Steve Bell -- The iMac List is sponsored by <http://lowendmac.com/> and...
