This is my second unit.  My first one arrived and the first day I had issues with the screen randomly shutting off.  Then that evening I heard it short, and flames came out of the vents under the Tobii thing.  It was a brick after that.

Took two weeks to get my second unit.  Got it yesterday.  Updated the BIOs and other drivers via the Alienware Update software, and then installed a couple games off Steam and Uplay.  Played a bit and it was running well for awhile, but now I'm getting the issue with the screen shutting off randomly again.  Just goes dark and is totally unresponsive.  Keyboard stays on and such.  Have to do a hard restart to get it back on.

Is this a known issue or are these things just a ridiculously expensive joke?  It's 1 day old (again!) and it's unstable.  I didn't install my own hardware....I didn't overclock it.  **bleep**, I didn't even adjust the lighting yet this time around.  Also, Dell didn't reset my 30 return policy while I waiting TWO WEEKS for a replacement....so I have to decide really fast if it's worth continuing with Dell.  Leaning towards not.....
