Intel Motherboards - Z77 Extreme 4 driver problems

New to an Asrock mobo as well as this forum. I just replaced my Intel mobo with http://www.newegg.com/Product/Product.aspx?Item=N82E16813157293 . I replaced the board and was installing drivers and utilities from the disk that came with the board, but part way through, during the fast xlan install the computer froze. It stayed that way for more than 6 hours so I switched the system off and rebooted. Since then I have tried to update driver for lan and install the xlan from downloads on Asrock site but every time it froze. Yesterday Windows 8.1 updated and now I cannot get the lan to connect to the internet. It may be worth mentioning that previously, when I was using the Intel mobo, I was using the Netgear software Net Genie. When the system froze the first time I tried uninstalling Net Genie thinking there may have been a conflict, but the system froze during the uninstall. Can anyone help me figure this lan problem out? At this point I am unable to connect to the internet with that computer. I have tried using the Windows network troubleshooter but it said it could not find any problems, but still will not connect to the internet. Please help!
