Hello all,

I just installed the latest beta Nvidia drivers (290.53) and my PC no longer recognizes my second MSI 560 Ti Hawk. It's getting power (fans are spinning) but the red lights on the GPU are not on.

I wasn't having any issues before the update.

System Specs:
i5 2500k @ 4.8 GHz
8 GB DDR3 @ 1600
2 x MSI 560 Ti Hawk
Asrock P67 Extreme4 Gen3

I would, and that's the first thing I checked, but there is no option to re-enable it. Nvidia Control panel is only showing one graphics cards. I haven't been able to figure out a way to make windows recognize the second card.

I'm sorry for not seeing it. My bad lol

If it was Z68 I would recommend a workaround, but it won't work in P67

ok, soo let me see if I got the order of events correct ..you had a working SLi system, showing both cards in the control panel. then you Updated to latest drivers, and now only shows 1 card. when you updated the drivers did you do a clean install, there is a checkbox option for that ..or did you get a second card and updated the driver ? perhaps you left off the SLi bridge ? I know I have done that in my hurry to get up and running ..if it was just the driver update ..try rolling back the driver to previous version

oh these are beta drivers ? sooo there might an issue with that particular flavor of grpahics that Nvidia might have to adjust ..but the you mention red lights on the Video card ? I am not terribly familiar with the "Hawk" versions ..what are teh red lights ?

After uninstalling and reinstalling the graphics cards (I had a working SLI system before the update), and rolling back the drivers to a non-beta release I got it to work again. I don't know what the issue was. I don't care so long as it works, thank you guys though for taking time to look into this.
