Driver "breaks" card ?

[TouchuvGrey]

i have a rig with two vidoo cards. My old trusty  GTX 460, and
my GTX 560ti. The 560ti works all the time but it seemed like
the 460 had died. Then it came back, "died" again, and is now
running.  Nvidia driver 350.12 installed currently.

     i did not notice it immediately but i think the 460 came
back about the time i installed 350.12.

    Has anyone ever run into anything like this ?

Grrrr, shoot that thory down. Same driver but 460
not working again. Will look for a bad connection for
the 5th time.
