Dell Power Edge T310 - Network Card Problems. -Applying computer settings /no internet connection

Recently our Power Edge T310 Server / on the network card, the connection has disappeared. At has not been available to connect either to internet, as well as internally. So it was suggested that the network connection on the motherboard was bad. to replace it. w/ F169G Broadcom pci-e, which we have done, it appeared to have updated, found the hardware, installed the driver, we disabled the previous network connection and updated the current one with the correct ip configuration, but on reboot, when it finally came to the screen  the ipv4 would not have the configuration in the ip adrs, domain and the subnet mask was gone, 

Now we get applying computer settings, hangs forever, and when it finally gets to desktop. when i try to access network sharing/to get into the adapter and change settings, its just a white screen it hangs....

suggestions or ideas?
