CCC not recognizing bottom card

[aceman1011]

So, I've been mining perfectly fine for a while until today. I had to reboot to test something, and when I did, whichever card I put in the bottom slot stopped working. I know the hardware is fine, and the bottom card works when the top card is out. This happened before I updated to 11.6, and everything was stable until now. CCC only sees the top card, although Afterburner and Windows see both. I tried enabling extended desktop, which did nothing. I don't think my dummy plug is the issue, but I will test that in a minute. When I run the top card alone, it works fine. When I run the bottom card alone, it only gets 300 kh/s. When I run them both together, they both get <1 mh/s. Help!

Fixed! Beware of the new XP security update. A quick system restore gets around this.

You should turn off automatic updates on all rigs if you have Windows.
Will save you a lot of headaches esp. in the form of not getting random reboots out of nowhere.

The reason why this is happening is because your processor replaces your graphics card on the list as device 1 (list starts at index 0) when the second card isn't being detected.

Yeah I learned about this one the hard way!

All windows updates disabled... If it ain't broke, then I don't want the patch to fix it.
