first time sli problem???

[GraveYard]

so ive just put my second 580 in to go sli.

the card that was in was a msi twin forzr 2 and ive put a pny with it.

now i put the pny card were the msi one was and moved the msi card down a slot i did this because the pny is a reference card and i thought i would be better in the first slot so it didnt blow on to the back of the other card.

when i first pluged all back in i put the dvi connector into the pny card turned on and it was like starting windows again with no video driovers and my keyboard and mouse wouldnt work. so i turned off and put the dvi connector back into the msi card whats now in the second slot.

so it works now buy my problem is. when i turn the rig on and monitor on i get nothing on the screen till windows asks for password its black till then so i cant go into the bios or anything..

how do i fix this???

try going back to one card, uninstall all your drivers then fit the 2 cards and try booting without drivers, if it works, then install drivers once in windows
If it doesnt, then ensure all your connections are good, what psu you running? does it work using just the pny card? if not, it may be faulty, if so, not sure

ive put the msi card back in slot 1 and its ok now. thanks for your help tho...

have you tested the pny on its own to see it work fine?

question why are the two cards only showing as using upto 70% of both gpu's???
