No Dump file, no peculiar events in Event Viewer. Acer TravelMate 5720, 3GB ram, Core2 Duo 2GHz, Windows 7 Professional. (Clean install) The bloody VGA: Ati mobility radeon "X2500" 256MB, you know, the one without a decent driver since its non-existence didn't begin. (as its x1700 in fact or something) A couple of days ago I started to get the black screen of death when launching Half-Life Episode 2, Launch the game, loads for a few seconds, i loose the cursor and the kbd doesnt "work" (no caps lock/ctrl alt del etc). Music stops (that im playing in the background with foobar). I have to power it off manually. I thought It was only HL2 the issue, since i can still play Counter Strike Source (same engine but indeed HL2 has more advanced stuff). So I tried with Starcraft 2 Beta, I see the loading screen and even the screen after that which is all 3D, with a spinning planet, game music goes on, a few seconds later - Black Screen. BUT music keeps playing, kbd again unresponsive and have to power it down manually (holding the button). Peculiar things/coincidental facts: - The first time it happened I was seeking through a XviD video file using Media player classic home cinema with the k-lite codec packs, played other files like that dozens of times before that problem free. - I think it started happening the day some Silverlight update was proposed to me via WU and i installed it. - When i get the Black screen, the next boot Foobar doesn't want to start (crashes on startup, no prompts, sound devices problem??) have to reinstall it every time. Dxdiag shows my DX is 11 and right now; 8.561.0.0 for the driver version (x1700, since I still hadn't managed to find the driver that will make it look like "X2500" in the "fantastic" acer support website) Tried "reinstalling" the driver if thats ever been possible with ATI products. Windows autmatically falls back. Scanned with various security software i use comodo internet security as my main thing, specially installed MSE, which didn't find nothing like everything else i tried (as in spybot s&d) So how do random things like that happen, I really didn't install other software except that silverlight update (i removed silverlight, no result) and Defender updates. Not that there are other vectors though.
