I recently got a 760 gtx 2gb. I was replacing my 6870 radeon sapphire 1gb. My current build is Intel i5 3570k asrock z77 extreme4 8gb ram 2 harddrives Evo hyper coolere 212 corsair tx650w I tried to install the 760 today, but I got no signal on my monitor and no beep. So at that point I remembered I had to uninstall my amd drivers for my 6870. Stuck my old cars back in, but now I get no signal or the usual beeps. All my fans run and my mobos debugging is lit up as usual. Not sure what the issue is. I reseated all the connections of my components. Reseated my ram. Cleared cmos. I also tried having neither cards slotted. Comp ran fine for 2 years until I tried to change vid cards. any have ideas on what maybe the issue? At the moment, I am shopping for a new psu since I need a spare one and on the off chance that is the issue. If not psu, its mobo or the new card did a booboo on my pcie3 slot.
