Having searched for weeks on this problem I've registered here after reading your impressive replies to similar problems.
The system is a recent build, less than 2 months old, and the problem has occurred from the outset.
S3 is enabled in the bios, which is the original Award (F3); rev. F8 is available but one attempt to flash via the internet failed (this mobo does not support floppies) and I had to clear cmos and rebuild the raid array using Intel's Rapid Storage app to get the system to post again and regain access to the bios.
I've tried to make an emulation floppy bios cdrom to update the bios but the program I used (Bart's clean20, which everyone links to in this situation) failed to insert the actual bios file when running the iso build.
A further complication: the latest bsod has corrupted the bios again (it's a dual bios mobo) and I cannot access it at post but the OS will load. I'd also be extremely grateful for the procedure to update the bios and correct this problem in one fell swoop if it's at all possible to do so.
A zip file with the problem report and dump file app's results are found here: Windows_NT6_BSOD_jcgriff2.7z
In short, quite the mess! I'd be extremely grateful for any help offered.
