@strangestranger: lol


ok the lights shouldn´t stay on - i think only one comes on on my 4780x2 then goes off almost immediatley.

Check the card is in the slot properly - it should snap in
Check the power cables are properly connected to it
if not it could be the card is faulty

Oh and post your entire system specs, just to make sure you´ve got enough power

Don´t worry though, the worst that will happen is you´ll have to RMA it, which shouldn´t be a problem

The lights indicate certain error messages. All of the lights will flash at post indicating the card has passed its self test. One light each for the power plugs being loose, one light for a temperature fault, and another indication (a fourth light or all of them on at once) indicating a critical core power fault.

If the lights stay on either the PSU is not powerful enough/broken, or the card is faulty.
