I'm sick of this problem , so I need your help.
First is the network problem. When I plug it in, two led on the network port of the motherboard doesn't light up at all. And I can't get to the Internet.But few days ago, it still flashed yellow light... That was when I was only testing the mainboard without the graphics card. I did check my network wire, I plugged it my Samsung TV, and it's works fine. On windows , It does recognized the network controller "Realtek PCIe GBE Family Controller" just fine.
Next is the audio problem.
Same case as the network, I plugged my headphone in, It doesn't recognize my headphone and doesn't allowed me to switch to Analog output, but rather still stay at Digital output. I tried to install new drivers and it's still the same.I even tried bunch of different headphones and they didn't worked.
My motherboard is Asus P5P41C , I bought it online, the seller confirmed the Network and Audio still working fine at the time he tested it, which was 2 days before I got my hand on the board.
