I have assembled computer in which I have MSI Z77A-GD65 motherboard. After connecting all the components properly I have install windows 7 operating system and then I have installed all the drivers in my computer, but Ethernet port is not working in my computer. I have right clicked on computer and then open device manger from the properties and when I see the Ethernet controller status at that it shows “This device cannot start. (Code 10)”. While installing the drivers I didn’t get any problem. if anyone have any solution regarding this problem then let me know.
