I then reboot, enter BIOS again end enable the onboard NIC. The PC boots perfectly with no network ofc. I can work aound this by first entering BIOS and disable the build-in NIC. Upgrading from the december 2009 BIOS actually was an improvement. Im using the March 2010 BIOS, which at present seems to have been withdrawn from the Intel site. I think I ran into an incompalibility between the 82578DC NIC and Microsofts bothersome build-in license software. I don't have any more to build for a bit, and in the future I will probably be using the DP55WB board if I am not gong to use the integrated video, but for me, this explains all 3 systems and my confidence in this board has been restored. NOW I am not claiming this would fix it for everyone, but I am pretty sure this is what I was running into and it started working form me when I did other things, but in reality, it was the hard power cycle after the bios upgrade that fixed it every time. After that, it started working and it hasn't failed yet. IT STARTED WORKING when I gave it the hard power cycle and made sure power was cut to the system board (I think I did this with the network cable unplugged). After the upgrade - NETWORK FAILED! I then tried rebooting with and without the cable plugged in, but it still didn't fix it. I intentionally left the network cable plugged in while performing the bios upgrade. I then loaded the additional drivers one by one, and between each driver I did all 3 (reboot, shutdown and turn on, shut down-hard power cycle-turn on) and it worked every time. I tried to get it to fail, restarting, shut down and power on, shut down, pull the plug, let the power dissipate and then plug back in and turn on, AND IT CONTINUED TO WORK.

I then installed chipset and network drivers and it worked. So on my 2nd system, I still left the network cable unplugged. I ended up using msconfig to force default video mode (see previous post) and then reenable the regular video mode and it started working and hasn't quit yet. I tried to disable it and reenable but still didn't work. I continued to load the rest of the drivers and when I was done the network card quit working again. I loaded the chipset driver first, then the network and the network showed a cable was unplugged, I plugged it in and it was working. On the first one, I made sure I installed Windows with the network cable unplugged. ANOTHER UPDATE- I have built 2 more of these machines.
