I'm stumped and running out of ideas.. Just got my EVGA gtx titan in last night so I couldnt wait to install it, so I did. I started with uninstalling the catalyst amd program, then using driver sweeper to remove the rest of the amd stuff,unplugged everything and removed the 2 hd6995's.(i have 3 -24 inch moniters hooked up to this also).Next I installed the titan hooked up the power connectors pugged in all the display cables, fired it up and, I get the beep and windows sounds of it starting up,,but no displays are working...all of them have the orange standby light on, not the green light.All the fans are spinning everything sounds good, the green logo on the titan is lit up ,looks cool,but...nothing.so far I have tried. swapping around plugs to screens,hdmi,dvi,ext.--switching to the lower pci-e slot---hooking the hdmi to the onboard display,,nothing so I put one of the hd6950s back in and the same issue,,nothing... Only Idea I have left is to reset the board Bios, its a z77 asus sabertooth. Has anyone ran into a problem like this or has any ideas please help,,stressed out...THanks
