I think that Ethereal is the wrong tool for this job. In your case 
using a manageable switch and checking the interface-counter, CPU usage 
and overall utilization is much more helpful then analyzing the network 
traffic. You're problem might be cause by any number of things, from a
defective NIC to a defective power-supply in the switch or even some
cabling problems.
