You having issues as well? I got my machine off ebay "as is" with no HD or proof that it even worked, but with a power supply and HD, it worked perfectly, except for the video card.
bios is showing it correctly, as a 675mx 4gb, but in windows, it just blue screens. I took it out and replaced it with whatever i had laying around (560m) and even getting that to work wasn't a cake walk. but through clevo's website (or was it Sagers? or Eurocom?) I got the legacy driver and Nview, to work. But this 675mx is... idk.. the vbios was updated or reinstalled, but It still just throws the blue screen watchdog error. Your's similar?
