I was getting a blue screen that said - windows exeption or - physical memory dump etc., I tried various things like, under-clocking & temp testing, this blue screen has caused me to re-format & clean install more than a couple of times, I was about to do this again until I remembered that I'd previously tampered with BIOS settings which could maybe have been a cause of B.Sc. so I just loaded the default BIOS settings, seems to have done the trick, no more blue screen.
