The last stable update I've been able to use for 6.7 on my machine was build 10176879 -- attempting to update to any of the newer patches / releases has been a failed attempt each time, getting so far as to start booting until appearing with the pink screen as seen in the image below. As far as I can tell the system BIOS is the latest version -- so at this point I'm a little bit lost as to what's causing the issue.
Motherboard: Intel S1200SP
BIOS Version: S1200SP.86B.03.01.0038.062620180344
CPU: Intel Xeon E3-1270 v6
RAM: 64GB
