a few days ago lightning struck my house, was a weird experience as the power flashed out for about half a second and there was a very loud crack. The only lasting effect seemed to be that our router didn't work. The router itself would no longer turn on leaving us without internet for a few days. We called our internet provider and they came out and replaced the router and got everything back to normal, i thought. I decided to get back on the computer after they replaced the router and to my dismay I couldn't connect to the internet. I tried a ton of things but it wasn't even showing up as connected to the router ( I use Ethernet). My computer is plugged to a surge protector so I don't think my computer was directly affected by the lightning strike. The issue that I think happened is that the lightning strike somehow affected my computer through my Ethernet which was plugged into the struck router and my computer. I think it somehow managed to fry my Ethernet because I purchased a new Ethernet which I tried on another computer so I know it works and it won't even register as plugged into my computer, anybody have any clue whats happening or if there is a fix for it? Would I have to replace the entire CPU? Everything else is functioning on my computer so idk. all help appreciated :).

Sounds like it probably damaged your Ethernet card if that is it then you were very lucky. Your easiest option would be to purchase a wireless or wired USB network adapter.

can I not replace the Ethernet card? currently am running on a USB network adapter but as an avid PC gamer I much prefer a stable Ethernet connection over a USB wifi chip

Have you already bought an Ethernet Network card ? If so try turning the built-in Ethernet card off in the Bios, the card may work then. What version of Windows is on the PC ?

TTD:
I've had thunderstorms and lightning kill the integrated ethernet device in 3 desktops during the past few years.
I solved the problem each time by installing an ethernet card and its driver.
That's one reason why I keep a couple of ethernet cards in my computer parts box.

You didn't describe your desktop and say how old it is, so it should have a PCI slot or a PCI Express x1 slot for adding an ethernet card.
Make sure you know what type slot is available before you buy one.
