So I can't check much.
Since Windows can use more than one NIC, did you try plugging in a new NIC?
(and of course the drivers for that new NIC)
A few days ago our tiny little town had a massive electrical fire that blew out power to the entire town. As a result of that, when I finally got power back and was able to turn my PC back on, I couldn't connect to the Internet(I also didn't have audio, weird but unimportant by comparison) . The other two computers on the home group could connect just fine(keep in mind all three PCs in the home are wired be a use WiFi here sucks bologna). And they connect fine, modem is working but I gave it a reset for good measure. I switched the cables around from PC to PC to ensure the wiring wasn't the problem(it wasnt). I've messed around with various things. I kept getting an error message 1068 : service group failed to start(same error I got for the audio problem)
So I Google my tail off and did all that, no change. I wanted to try disabling my NIC card and then re-enabling it to see if that would do anything, and/or reinstall drivers else, etc. So I went into my system info and attempted to locate my NIC card, but it wasn't there. My conclusion/assumption is that my NIC card is fried due to whatever happened with the power due to the fire.
So I open up my case to remove it and purchase another, but this nic card doesn't look like any that I've ever seen, it's a small metal box, no screws holding in to the motherboard and I can't seem to remove the same thing. Granted, I haven't been to aggressive about it be a use I don't want to break anything, but if I want my PC to be anything more than a glorified paper weight I really need to install a new NIC.
Is it possible that it# well and truly attached to my motherboard or am I just an idiot?
