No SLI in Nvidia Ctrl panel

[Blackwhite]

Hi guys.
It hapend to me 2 times within 4 days.After night when I switched On my PC I got LCD res 800x600 and I had to reinstall drivers (260.99), after that theere is no SLI settings in nvidia ctrl panel, can see two cards for phsyx but thats it.Last time I had to remove both cards from PCIE slots and that help, but it is not solution for me doing this all the time when crashing.
I noticed that when unistalling drivers and installing again, windows installing his own drivers for GFx cardAny ideas? and always intaallation of one of the card is faild.
any ideas?

check in device manager that's its showing both cards (probably yes as NV control panel sees both).....and have you got the SLI bridge installed ?

Yes it showing both and yes I have SLI bridge mate.It was working fine testedrady.

its weird...I've had problems with my 580s in SLI....turns out they werent pushed fully in to the slots. Only thing I can suggest it re-seat the cards, re-connect the SLI bridge and see if theres any difference ?
