So yesterday I bought a brand new, 1,000W PSU to replace my 650W one and to allow for SLI. I install it and my second card (both are GTX 560 ti cards). I reinstalled my drivers and my system recognizes both cards. The control panel says "GTX 560 ti x2", I can select between them for Physx, sound output, picture output (although I only have one hooked up to my monitor), etc. But the kicker is I can't turn on SLI. Everything I've read says I'll get a balloon notification saying I can use SLI and the control panel will have a new section, etc, but none of those things happens. Anyone have any ideas?
System:
Win7 Professional x64
2x GTX 560 ti
3.1 GHz Intel Core i5
1,000W Xion PSU
8GB RAM
(Can't think of my motherboard right now)
Note: My PSU and MOBO both say they're SLI certified and I'm using an SLI bridge.

Check your BIOS settings. Some motherboards need SLI enabled in BIOS. – MBraedley – 2012-07-10T14:39:12.390
I looked around for that in the BIOS and in the manual for the MOBO. Nothing in the manual, no settings that seemed relevant in the BIOS. – Nakaan – 2012-07-10T14:42:33.167
Would need your motherboard info to check, it may need a BIOS update. – HaydnWVN – 2012-07-10T15:52:51.250
It's only a few months old, but I'll definitely look into that after work. – Nakaan – 2012-07-10T16:00:31.650
Have you checked the firmware and driver versions? – Diamond – 2012-07-24T10:23:56.017
