Power surge .....insane network problem

Setup :
Cable modem, two computers that are not networked due to a down
router, both XP.

Power surge the other night, definitely killed my network router
(along with some TVs and a garage door opener).

Problem :
I currently can only get internet if the cable modem is hooked into
the integrated network port on one of my computers (call it Computer
A). If I plug it into Computer B's integrated network port, I get the
error "network cable unplugged". I know what you're thinking....fried
network card. But I added a PCI network card and it still won't come
up. Ok, bad motherboard on Computer B. But, if I take that network PCI
card and plug it into Computer A, it won't work on Computer A
(although the integrated network port on Comp A works fine). Ok, bad
network PCI card. Bought a new one, different brand....same thing.
Called cable modem company, they reset the modem on their end and I
power cycled it on mine. Same thing. Changed all the network patch
cables, no help. I am not even getting any link lights connecting the
cable modem to these network ports except for the integrated port on
Computer A. Releasing and renewing the IP does not work cause of
media disconnected (except on the one working port on Computer A)

So the cable modem only works on *one* port on *one* computer. I've
tried every kind of combo I can think of and it won't work. The
network card installs fine in XP. I've tested the PCI slots with
firewire cards and they seem to be okay. What on earth can be wrong?

Power down the cable modem for a minute. Then try comp b again.
