Does the green light on the network cards light up or flash when you connect
them?
If there is no green light on the NIC when you connect the cable (through
the house) that means that the connection is defective, most likely caused
by the cabling. The way to prove it is to get all the pcs in one room and
plug them into the switch. if the green lights come up on the NICs
connected directly to the switch then you can be certain it is a cabling
fault.

not likely, but the switch could be faulty.

plug 1 piece of cable you know to be OK between network port of 1 nic that
you are certain works (e.g connected to modem router) and one by one to
other pcs. preferably cross-over cable.
if the green light comes up again then the nics are OK.
If it's not the cabling or the NICs then the network isn't setup correctly.
