I think my 5870 2gb is dying or dead.  The VGA led on my asus crosshair iv is staying red.  I can't get a bios post.  This started about 2 days ago, I would play some black ops for an hour or so, and then my screen would freeze and lock up the pc.  Upon reboot the led would stay red, I would then reboot again and it would fire up to windows as if nothing happened.  Wandering if the average lifespan of this particular card is 2 years.  It's  never been over clocked.   Any help would be great, I'm gonna get a spare card and try it out tomorrow.
Steps completed:
  Cleared and jumped CMOS
  Reseated power connections
  Reseated card ( all 4 pci-e lanes)
  Disassembled card re-applied thermal paste
  Disconnected all components and ran bare minimum
  Swapped out mini-display port adapters
  Submerged card in battery acid
  I've tried everything under the son, with no luck.
