Ethernet port broken?

Microsoft Windows 7 ultimate 64-bit
January 1, 2010 at 14:44:47
Specs: Windows 7, AMD x4
Recently i have been moving some stuff
around my pc room. in the process my printer
was unplugged. about a day later when i
actually needed to print something. I plugged
the printer back in (the wire fell out of the
printer not my pc) I am not sure if any of this is
relevant but right after i plugged the printer
back in I was told that I was disconnected
from the internet. I run the windows 7
diagnostics and it says I have no Ethernet
cable plugged in. I have tried plugging a diffrent
wire in, restarting, checking my bios to see if
the hardware appears, and crying/vomiting due
to massive internet withdrawal. only other help
that i can provide is that when i plug an
Ethernet cable in a green light flashes at
intervals of 1 second.

What does your ethernet cable plug into? A modem or router?
Whatever it is have you done a power down / reboot of that device? It is possible that when you re-connected the printer cable, it caused a power spike through your motherboard. Sometimes resetting each device in the chain is all it takes to rectify the situation. It is also possible the powerspike has damaged the ethernet controller on your motherboard. If that's the case you have two choices. Replace the motherboard or (if there is an available PCI slot) get a 10/100 PCI network card.

what does the green and orange light mean on my Ethernet port?
I'm pretty sure green means sending packets and orange means receiving.. if so wouldn't this mean that the port is functional?

Not if it is flashing at constant regular interval. Did you power down the modem/router?

also, if I do need to buy a pci card for my pc, about how much
does this cost? are there any possible alternatives that would
save me money? My budget is terribly tight right now.

Not normally. The orange light is usually a link light. It should light as soon as both devices at either end of the cable are connected and powered up. It indicates a physical connection. A blinking light there mans there is no physical connection, either the cable is faulty or one of the devices is faulty. This is before any software comes into play.. The green light will flash regardless of which way that data is flowing. Some devices will also have a third light that will indicate what speed you are connected.

PCI Ethernet cards are as cheap as chips. A search on Google will give you many options.

Your cable could be no good. Plug the computer in with the cable from a computer that is working and test. If it works, you've ascertained the cable was bad and needs replacing.

If it doesn't work, then your NIC could be bad.
