nvraid.sys BSOD on W7Pro x64 when second drive(s) added

Hello,

I have a home built computer that was working wonderfully with Windows XP, however Windows 7 Professional 64 bit has been giving me some headaches. Here is my system info...

OS Windows 7 Professional 64 bit
CPU AMD Athlon 64 x2 3800+
Motherboard MSI K8N Neo4 Platinum Motherboard
Memory 2 GB
Graphics Card Quadro FX 4500
Sound Card NA
Monitor(s) Displays Dell 3007WFP
PSU Seasonic S12
Hard Drives 2x 250 GB Sata Raid (Mirrored) 2x 1 TB Sata Raid (Mirrored)

I did a clean install a few days ago. I can get Windows 7 to install perfectly on a single pair of mirrored Sata hard drives. I set up my machine with the system and all of my programs on this drive C: Everything works great. I keep all of my files on a second set of drives F:.

When I shut down the machine and add in another mirrored raid of two Sata hard drives F:, the machine boots up and I can see the F drive and read and write from it for about 2-3 minutes and then consistently BSOD's.

The blue screen points to a driver failure. Nvraid.sys DRIVER_IRQL_NOT_LESS_OR_EQUAL.  I have a .dmp file with the crash but I'm not sure how to share it here.

I'm at a bit of a loss as to what to do at this point. I've tried Microsoft tech support and they just threw the problem to nVidia, which I doubt will support this 4+ year old motherboard, but who knows. I may have to go back to XP until this gets ironed out or I upgrade my motherboard. Any help I can get would be greatly appreciated.
