I've been putting together a new rig and found out that the ethernet controller is not working. It's been bothering me for the past few days. I'm thinking it might be the motherboard.
Anyways, I have a MSI Z77A-GD65 Motherboard with core i7 3770k running Windows 7 pro 64 bit.
I tried installing the device drivers that came with the MB disk. There is still a yellow exclamation point in device managers. When I open up the device properties, i see a "This device cannot start code 10" message. I also uninstalled and tried installing Windows generic Ethernet controller driver for windows 7 64 bit.
I also used CCleaner and reinstalled the lan network driver that came with the MB disk.
