On the PC with no internet Click Start > Run, type in cmd in the field hit enter.
In the command promt that comes up type in "ipconfig /release" hit enter. No quotes in the command.
Then type "ipconfig /renew" hit enter.
Once that command completes try to get online.
If that does not work, type in "ipconfig /all" and post what the Default Gateway and DNS is listed as.
