So I've had a wired connection in my house that I've been using for a lomg time now. Back then, when I would use the PC, it would recognize the cable and even the lights on the port would blink the yellow/orange thing.

It just suddenly stopped working a few days ago and I assumed that it was the cable, so I replaced it. But then it still wouldn't work, so I borrowed my family's htpc and plugged the new cable in and it worked. Then I fiddled around and saw that, when connecting my pc to the htpc one, my pc detects the other one; and it even blinks! I could share files and etc.,

It doesn't make sense how my pc suddenly stopped detecting the cable from the router to the pc as I haven't changed anything in the settings (because of deepfreeze.) Also, could it be a hardware issue since it involves the lights on the port of the motherboard?

In summary (in order of my testing):
1. Old Cable to My PC = X
2. New Cable to HTPC = √
3. New Cable to My PC = X
4. HTPC to My PC = √

I don't know if this helps, but the one I use from the router to my PC is around 20m long. I don't think it's relevant since it was working fine and then suddenly stopped working.

Network cards do die. That's why it's useful to have expansion slots so you can add another one.

Look inside the jack and if none of the wires are bent or dirty, then there's not much else to do but replace it. And depending on what died, it may still show up as installed in Device Manager too. A warning: the MAC address of the NIC is one of the primary things that triggers deactivation of Windows, so you may not want to disable it even if it doesn't work.

Don't worry too much, you can head over to amazon and pick up a new one. When you choose what to buy pick out a CAT-6 Ethernet cable. Should be able to pick up a 10-15 foot cord for under 10 bucks. Just don't bother going to local stores unless you want to pay at least twice the price for a cord.
