Can't Get NVidea Network Card to Work With Centos 7 (It worked with 6.3)

Hello, I just installed CentOS 7 and the OS does not see the NIC. This worked fine with CentOS 6. Can someone point me to the procedure to getting this to work--and before you tell me to Google it I have been Googling all morning. If you're able to talk to me like a 5 year-old and give specific steps I'll appreciate it. I promise not to be insulted! Rebuilding kernels are not my forte'.

Thanks!
