Test #1:
Move your laptop by PC #3 and test with PC 3's network cable and see if the laptop works. If this works, there's something wrong with PC #3. Be it network adapter or windows problem.
Test 2:
Find out which network cable is used by PC 3 at the router, remove it and plug in your laptop into the same port with a different network cable and test. If this works as well as test 1 failure, then the network cable between the router and PC #3 is duff. If it doesn't work there's something wrong with the RJ45 port on the router that PC#3 uses (try the spare port on router)
