Issue installing GTX 780 Ti

[ISleepTheDayAway]

I recently took out and sold my two Radeon 7950s, I've had my old GTX 560 Ti running in my PC for the current time.

My GTX 780 Ti just arrived and I did the usual for installing it. Nothing will show up on my displays. After it not working, I put my GTX 560 Ti in with it to see if I could get anything to display. Nothing.

I took the GTX 780 Ti out, and just booted with the GTX 560 Ti and I got Windows running. After some HDD checks it booted, at a very odd resolution due to the lack of Graphic Drivers. But it booted, I tried installing the GTX 780 Tis software, but it gave me an error due to lacking the proper Graphic Hardware.

I put the GTX 780 Ti back in the pC, rebooted. And no display again.

Even with the display (HDMI, but I also tried DVI/VGA/Display Port) in the GTX 780 Ti, 560 Ti, or just plugged into my Mobo no display.

Plugging it directly into the Mobo makes my display say "Searching for signal" but nothing happens after a few seconds and it goes back to "Weak or No Signal" any ideas?

EDIT: Also with the GTX 780 Ti in the computer doesn't really "boot", I can turn it off with a tap of the power button instead of holding it down. It just sorta "turns on".

Whats your motherboard model?
Sometimes a bios update for some mobo's is needed , I know it sounds crazy but it has been happening to some users.
Is the power correctly plugged in to the 780ti, what psu are you running?

Check that you have the latest bios for the mobo, update it and try and boot it again with the 780ti

Updated bios via Instant Flash, same issue. Computer booted properly with just the GTX 560, but when booting with the 780 there was no display. I did try booting it with both cards still in, will that make a difference? I was just sick of swapping them in and out the past couple hours.

EDIT: Just took out the 560, it's displaying now. But telling me to power down and put in the proper PCI-E cables. Which I have. - http://i.imgur.com/aadN7sX.jpg http://i.imgur.com/kkHbkxt.jpg http://i.imgur.com/1RQrIeW.jpg http://i.imgur.com/l3CNENW.jpg

Try the 780ti in another pci-e slot and see it that works?

Edited last post with Pics, am about to change PCI-E slot.

EDIT: Sounds like the card is really going now, fans are going super fast. Sadly no display now, and the tapping to power down is still a thing

EDIT: I DON'T KNOW WHAT I DID. I THINK IT NEEDED MY BLOOD AS LIKE A CONTRACT WITH THE DEVIL. BUT I DID IT. (Fans kinda knicked me and fed off my blood twice)
