new motherboard's onboard lan is dead i guess

I bought new motherboard 2 days ago. I installed windows 8.1, drivers etc. Everything was okay but today when I wanted to open my computer, I saw internet didn't working. Ethernet port's led doesn't light.

I tried the same lan cable in other pc it works perfectly. The problem is onboard lan obviously. So is the onboard lan broken? How can it suddenly broken?

Did you use the latest drivers from the mobo's website? Have you configured it to match your ISPs settings

Yes I did all of them but lights are not turn on. Ethernet port never respond

I solved the problem. Just do CMOS and reset the bios. In BIOS ethernet was on. Everything was okay but the main problem is when the pc goes deep sleep, ethernet card never awake.
