Transmitting but Not Receiving Packets on NIC

Trying to get a friend's PC working with Comcast high speed internet at
home via cable modem. Having some strange software issue with the PC.
I installed a known, working NetGear NIC and related drivers in the
Gateway PC that is running Windows XP SP1. (I had to install this NIC
because the onboard Intel NIC with latest drivers was "flapping" -
would continuously go between "enabled" and "disconnected" states).
Windows shows the status of the NetGear LAN Connection as "Enabled" and
the link light LED is green and showing activity. However, the NIC
statistics show that packets are being transmitted but "0" packets are
being received. I had Ethereal running on the PC and it shows the DHCP
Discover packets being transmitted (reflected in statistics) and other
DHCP broadcasts for other MAC addresses.
I plugged 2 other PCs into the cable modem and both obtained IP
addresses right away. Therefore I know that Comcast service is working
properly and providing addresses via DHCP.
I know this is strange but my guess is that there is some software that
is installed on the PC that is preventing packets from being received
by the NIC. I tried uninstalling AOL, Norton AV, and Spy Sweeper
software and still saw the problem. I also tried enabling/disabling
the windows firewall.
At this point I've run out of ideas and asking for help from anyone out
there that has seen this problem before or may have other ideas.
Thanks,
Z
