Maybe its your router that fried, so your pc cant get an IP.
Or its your modem which fried, so you can't connect with your ISP.
Or maybe its just the wiring in your home/block that got fried. Highly subjective though. Try resetting your router/modem and see if you get all the working lights.

go to start -> run and type in cmd.
At the prompt, type ping 127.0.0.1

That will do a ping test on your NIC card. If it fails, then your NIC card is bad. If it passes, try switching to different ports on the router/switch to see if it blew the port out.

This is what I get when I typed it

Packets send = 4, Received = 4, Lost = 0%
Approximate round trip times in milli-second:
Minimum = 0 ms, Maximum = 0 ms, Average = 0 ms

So... is it busted?

Nope. The NIC should be fine. What this tells us is that the NIC was able to send (so the transmit unit is ok) 4 packets to itself, and then it was able to receive (so the receiving unit is ok) without any errors. Try reseating the NIC (if it's a PCI card and not one of those built onto the motherboard). If that doesn't work, right click my computer, go to manage, then device manager. Find the NIC controller, right click, uninstall. Reboot, then windows should prompt you to reinstall, either download the drivers with another PC and put them on a thumb drive, or use the mobo\
ic driver disk\\CD.

127.0.0.1 isn't it loopback for the OS, not for the NIC. So to test the NIC you should ping the interface. In this case set IP manually and ping it.
Am I right?
Logically if you have 2 NICs, 127.0.0.1 which one would test?

I'm relatively sure that when you use the ping 127.0.0.1 an actual echo is generate, however it's passed across your card rather than down the wire and echo'd back from another source. I could be wrong though.

Logically speaking a home OS is not intended to use 2 LAN connections, and one is always prioritized, so using ping 127 would go to that NIC. In a server or router, you have to "move" to an interface to ping from it specifically, otherwise the device uses whichever device is best\\can be reached, etc.

K what I tried was going to device manager and uninstalling the network card NIC... then I rebooted but NOTHING was "reinstalled" again. When I went back to device manager, the NIC title was there -so I tried to "update/repair" but it didn't even read it oO

So then... second option is how do I reset a onboard network card? I'm looking at the opposite side of the ethenet (on the inside) and see a small silver box that's almost un-removable simply because there's no room to put my fingers in it even give it a good shove of the computer (no screws... really hard on the motherboard).

Any advice?
