I got the exact same problem like urs, mine is 500 gb simpletech nas, since like simpletech is out of the business/ been took over by hitashi, any solution u found..............
Problems, first--- my 700m got blank screen after your instruction step 5 (right after install the driver which you recommanded) I have to shut down the pc manually then restart again. after pc rastart, yes it does boot into 1280x800 but video won't play properly. Any solution??????????????
