BSOD double fault troubleshooting problem

Hardware:
Rampage III Formula (http://www.asus.com/Motherboards/RAMPAGE_III_FORMULA/)
Intel BX80613I7980 Processor
Nvidia Quadro 2000 by PNY Adapter
WD HDD 450 WD450HLHX VelociRaptor 3.5 1000RPM - 2 in onboard RAID
4 x 4GB DDR-1333 RAM
740W PS

We built 5 of these in October 2011.  Four are working fine.  One has BSOD 0x0000007F  [see attached]  This indicates a double fault error typically associated with RAM problem.  Here is what we have done so far:

1 - Swapped out RAM.
2 - Swapped out Processor.
3 - Swapped out power supply.
4 - Swapped out video card.

The computer will not boot to onboard Win 7 Pro OS.  It will also not boot to a CD Rom of Windows 7.  It WILL boot to Ubuntu.

We are left with motherboard by process of elimination and are currently disassembling the computer to try to boot outside of the case.

Any other troubleshooting thoughts?

Well, you have narrowed the problem to motherboard. If you have there a latest BIOS installed then all you can do is to replace the motherboard.

Test the RAM using memtest86+. It is included on the UBCD:

Make sure your mainboard is set to failsafe or default settings, and not in any way overclocked.

Zip your last 3 minidump files and attach that zip file with your next comment.

you did not try to boot this problem one from a working disk on another PC?
check also the bios - and update it if you have a new version

My apologies for not responding to comments sooner.  We went round and round having tested most of what was suggested (but for the RAM test.. my test for that was changing out ram entirely since I had some here).
It looks like what was happening finally ended up being a RAID issue.  The ASUS comes with two types of RAID.  Marvel and the standard Intel.  When we first set this up we defaulted to the Marvel RAID (red sata drive plugs.. made sense at the time).  This worked for three years and then decided to start blue screening with the info above.
We killed that RAID, changed over to the Intel RAID and now it will boot just fine to a Windows OS disk.  

Thank you for the suggestions.  This one is done.

Never, ever use any of the RAID functions of any of those controllers, they are mere fake-RAID controllers and highly unreliable. If you want to use RAID, use the OS's built-in software RAID. It is far more reliable, and also performs better.

Finally found that the Marvel raid was causing the problem.

Self induced error three years in the making.
