so after a few days of totally bsod-free computing... i just installed a new bd burner in my system which i have attached to the on-board sata ports. i moved my 7240 (which has a problem burning dvd's all the way thru, so it'll be my ripper) to a kouchtec add in sata controller card, as it has good speed and firmware for those tasks. these changes seem to be fine, as i've both ripped and burned stuff successfully... but two times now i've stepped back to the computer to find it's bsod'd with a 3b stop code seeming to point at dxgkrnl.sys (although these reports look at different components than what i originally read)
i see the two smalldump files sitting on the d: drive, so that worked successfully...
they show up as "DUMP3b2b.tmp", and "DUMP384e.tmp", and are only about 280 KB in size. i loaded bluescreenview from nirsoft, generated a html page (is there a better report i can generate?)...
i should add i've run memtest on this system with no errors on a pass, the ram is set to run at 1066, which is clocked down from its native clock.
both times the bsod's happened, the computer was sitting idle after ripping and writing dvd's.

EDIT : and now just got another one just sitting here reading this post, here's the report...

so that one was totally different. gonna drop this ram down to 800 speeds for now, see if that ends this.
