  1. If it can help it happened randomly while playing , the monitor turned black, I plugged the monitor in second card and it worked , now in system properties I have 2 GPU instead of 4...
  2. use gpu-z and cpu-z and see what card not seen. then power down your pc. unplug the crossfire cable and move the dead card into the other card slot and see if the card is still dead. if it is dead and it under a year old it should be under warranty where you can rma it. (if the vendor replaces that card with a newer card you have to replace the other card).

    I hope you have a really good power supply for those two cards. Are you sure you didn't partially blow your PSU?
  4. Got a 1200 W , I think it's enough, I just installed fresh drivers and its working back to normal.


    Is there a way to check if I caused any damage to the card ?
  5. What make 1200W?

    You could have a 1200W PSU but if it is made by a rubbish manufacturer it wont power anything very well.
  6. A corsair 1200 W, I think its good. AX1200 written on it.
  7. Can you try 1 card at a time? Sounds to me like 1 has failed or the slot its in went bad.
  8. I updated the drivers and they are working fine now, any ways of checking if I done nay damage to them ?
  9. That is a good PSU. I would try what smorizio said and swap around the cards, to see if one of them is playing up.
  10. It just happened again, could it be because I have too much plugged in the same power bar , been doing this since we are playing 2 computer on the same power surge.

    Got 2 gaming computer each double graphic card at 1000w and 1200w, is it too much ?
