First off, HEY to everyone....this being my first post here! Hope to learn a thing or two, maybe enough so I don't have to toss this card out.
 
Problem: My machine is an eMachine/Vista 32 Ultimate SP2/Core 2 Duo/4 gigs ram. Been using the onboard graphics but wanted to use the HDMI on my 22" monitor and add the 1 gig memory for the video chores. Installation went well and everything works perfectly...YouTube, DVDs, a few games I play (not heavy graphic games, though), general surf and so on. No problems. Until I get on Netflix. I might can watch a few minutes or so and then, suddenly, the screen goes completely black, the audio plays for a few more seconds and then starts stuttering and then quits. Since the screen is black the only thing I can do is push the on/off button until the computer goes off, then restart. When Windows comes up I get an error message (Windows has recovered from an unexpected CRASH) that lists a BCCode 116. I have been researching that code but not much on it.
 
Treatment So Far: I have uninstalled/reinstalled the latest drivers (340.52), reset card settings to default, uninstalled/reinstalled Silverlight, cleared the Netflix cookies, no antivirus running, no viruses/malware problems, no firewall issues and conversed with a Netflix support guy (Netflix cookies suggestion).
 
As I said, the video is perfect for every task I do otherwise. When this problem occurs the machine does not make any additional sounds (HD spinning, fans revving up, etc.). If anyone has any thought on this I would like to hear it. Otherwise, I will have to resort back to the onboard graphics (Netflix works fine with it) or maybe try an ATI card.

Hmmm, good idea. I will check this out after work tonight. I have another monitor but it doesn't have HDMI.

No good on the VGA change over. Blacked out 3 times tonight in a 90 minute span. As for the Chrome idea, that is the browser I have been using. Maybe if I tried IE or maybe FF? I'll try those and get back.

It's odd that it would behave that way, I was leaning towards it being an HDCP issue. With it happening on VGA, that's out.
 
Vista SP2 Ultimate should have Windows Media Center included, I know Win7 Ultimate has it, since I use it daily. You can try loading that and see if loading Netflix there has the same issue. 

FIXED!!  So far, so good....
 
Did a fresh install of Vista, only updated the C++, .Net framework and Silverlight.  Watched 3 continuous hours of Netflix (sheesh!) and not one little hiccup!  The card software says that there is an update for it but I am holding off a while.  Besides there was nothing in the update notes that applies to this card specifically.  
 
Thanks for the suggestions.  I know that a complete OS reinstall is a bit drastic, but, like the cartoon character Foghorn Leghorn used to say...."I always keep my feathers numbered for such an emergency"!
