Any one please help me.. I am getting an APIPA since three days.. I did all the steps mentioned in answers to this question. Still they did not resolve my problem. At last I formatted whole of my computer and installed windows 7 all over again. Now my computer has only windows 7 (I mean no anti-virus, no firewall, not even a single software) and my IP is still169.x.x.x (APIPA). Please help me regarding this issue. I even changed the ends of my Ethernet cable. Is my NIC has gone bad and should I replace it?

"I did all the steps mentioned above" - what steps? –  Keltari Jan 23 '13 at 7:15
What is the Ethernet cable connected to? Do other machines connected to that same device work? Is the port light on for the port connected to that computer? –  David Schwartz Jan 23 '13 at 7:16
Probably refers to superuser.com/questions/324551/… where he's posted the same thing as an answer –  Journeyman Geek Jan 23 '13 at 7:20
-Ipconfig release/renew -Uninstalling/reinstalling the NIC driver -Checking device manager for "hidden" NIC drivers (none) -Flushing DNS and ARP -Resetting winsock and ipv4 using netsh -Manually assigning an IP address on my subnet -Doing a system restore to before the Windows update -Restarting DHCP client service -Disabling Windows Firewall -Unloading TrendMicro -Malware Bytes scan –  Shashank Jan 23 '13 at 7:27
these were the steps which I performed earlier.. @Journey Geek : YEs I wrongly posted it as an answer to the other post.. But This ks the problem which I am facing. The Ethernet Cable is connected from one end (port no.1) in the router to back of my desktop. But I cannot see any light at the back of the CPU where I connect the cable. But when I uninstall my NIC from device manager, on restarting, windows automatically detects my NIC and installs it. What should be my next step? –  Shashank Jan 23 '13 at 7:32
