Ok first of all thank you in advance to anybody that actually reads this and trys to help me out. I like to think I have some pretty good computer experience but i dont think i've had a problem yet that pissed me off as much as this one.

Background info:
Im running Windows vista 64bit
I have two integrated Realtek ethernet ports
And...thats probably all you really need to know about my computer

So this is the whole story. Im living at college and i went home for the weekend. I came back on monday to find my internet not working. So the first thing i did was try a different ethernet cable, and it worked. For about a day. And then it wasn't working again. So I did ipconfig in the command line and it said that there was no media connected. So I figured it was either the cable or the jack in the wall.
I tried 3 different cables that i KNOW work, none of them worked. I had 3 friends try their laptops on the same jack in the wall, it worked fine for them. So its not the cable, not the jack, must be the computer. So I looked under the device manager and it said that both ethernet ports are working properly. About a month or two before, I overclocked my CPU about 600 MHZ, so i thought that maybe the system was instable. So i ran prime95 and it was not stable, so i returned the CPU to the stock speed, i ran it again and it said it was stable. So then i returned my BIOS to the defaults to make sure it was EXACTLY the same as before. Still not working. I tried a new ethernet card, didnt work. I tried reformatting my hardrive and reinstalling windows, still cannot get the ****ing internet to work. WTF!? Everything else works, the ethernet cards show up as working properly and everything, it just says that there is nothing connected to it.

I assume since you re-formatted that you have your PC set to automatically acquire an IP address, but you may want to check that. Is the data light lit on your NIC where the cable connects? Can you ping the loopback 127.0.0.1, that will tell you everything is working internally on your NIC. There's other things to try too, but lets make sure your these are correct first.
 
I am away from my computer(obviously) but i will try pinging 127.0.0.1 when i get back. I can tell you that the light does not light up when you connect the cable, it does not light up in either of the ports. Oh and i forgot to mention, i did not completely reformat my hardrive, i made a new partition and installed windows on it so i can still get to the old partition.
 
I typed ping 127.0.0.1 in the command line and returned the following.

im assuming that means it worked...

Tried updating the drivers for the NIC?
 
I ran a realtek diagnostic program and it said that everything passed. I checked the cable section of the diagnostic and i didnt really know what it was talking about. Check the attachment.
