you don't say whether the switches are managed or unmanaged.

with port security on a managed switch, only the computer with the assigned MAC address can connect. On Cisco switches, typically what happens is the port is disabled if an unauthorized computer tries to use it. Only the administrator that knows the switch password can turn the port back on.

Given that you tried the old computer and that works, new one doesn't, the port doesn't seem to be disabled.

if your not on the same subnet, you won't pass packets so that might be the problem.

need more information. subnet, gateway etc.
