  8. You cant remove or install a laptop card.......
    Therefore you cant xfire it......
    You only have one video card in your laptop...
    Sorry bro.

  10. Did you go back into hardware and look for the second card?
  11. yes it has dissapeared....thats the odd part and really my whole issue
  12. Well its in your computer on your motherboard. you cant really replace a laptop video card. So It could be faulty. Id RMA it if i could.
