So, I poked the machine some more. I ran Driver Verifier. It didn't like it. It went about 30 minutes until the first BSOD. Then it kept freezing/restarting. Had to disable in safe mode:
Here is the NT6-Report w/ mini-dumps (found below). This is #2 of the NT6-Report. The other can be found in the first post.
Here is what "WhoCrashed" had to say:
On Tue 4/3/2012 3:57:05 AM GMT your computer crashed
crash dump file: C:\Windows\Minidump\040212-23306-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x7CD40)
Bugcheck code: 0xC4 (0xE3, 0xFFFFFA800F0D1531, 0x73BF278, 0x0)
Error: DRIVER_VERIFIER_DETECTED_VIOLATION

Bug check description: This is the general bug check code for fatal errors found by Driver Verifier.
A driver has made a call to a kernel-mode ZwXxx routine with a user-mode address as a parameter. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

Hope this helps
