on the computer with trouble:

ping 127.0.0.1

If that is anything more than 1ms, then you need a new NIC.

If it comes back fine, then check your NIC driver, make sure Windows IE7 is not installed, try safe mode WITH networking (will eliminate most software issues it could be) or just break out the hammer and beat the crap outta it until it works right.

Best of luck, if you need anything else... please post again :)

Sounds like a bad network card. Try reinstalling the network card driver (updated) first. If not, try a different network card.
maybe your motherboard doesnt support speeds that fast. If it is an older mobo than this is probably the case. good luck.
So is this PC connected directly as well or wirelessly? It could be a problem with the order QoS(quality of service) setting in the modem that sets the one PC to have a much better control over the bandwidth. Try disconnecting that good PC and then just run them with the other PC.

If I have this correctly, you have two PC's connected to this modem and one has good pings and the other doesn't?
