Windows 7

And what we know about teamwork NVidia and ATI cards?

If those two werent so stubborn marketing enemys, we could get motherboards cheaper and better.
While technically easily to archieve, very few Motherboards out there support both SLI and CF. Nvidia and AMD forbid that boards supporting their system also support the other. If the manufacturers could use the extra money and time spend to make 2 boards, one of each kind, to make one, it would be cheaper and better.

I never blame the operating system
I have no cards in sli and my problem is not on my Titan but also on my Windows Professional.

I received a reply from support they do not know this problem, who tell me to remove all the available devices sound others drives etc etc and try.
then tell them if that's ok
