I would guess you have a switching loop some place and could be suffering a
broadcast storm.  This could be initiated from a faulty NIC. We had a
similar problem couple of years ago and replaced all unmanaged switches with
managed ones and enabled STP.  This stabilised the network and stopped
switching loops/broadcast storms.
