Thanks for taking the time to help me out.
I'm attaching the results of the sfc /scannow though from examining it I don't think the repair actions would have helped with the BSOD. All repaired files were Windows 7 video and audio codecs that I purposely disabled.
Regarding USB devices in use... it's pretty minimalistic. Just a plain USB mouse and USB keyboard... nothing needing explicit drivers
of their own.
From searching I think someone has encountered a similar issue to me. http://www.sevenforums.com/crashes-d...-bugcheck.html
My memory related voltages aren't set to auto / stock so what i'm contemplating on doing is upping the QPI voltage and loosening the timings / lowering the multiplier.
I'll see if I can reproduce the BSOD (or any BSOD) with my relaxed memory setup.
