Having a heck of a time getting this card to run and from what I'm seeing there's some compatibility or bios setup I'm missing that this card needs. The mobo is an Asus P8Z77-V LE with z77 chipset, i7-3770k, 16gb Corsair 4x4, Corsair AX860i PSU. Card initially booted to Win 7 x64 Pro fine. Installed drivers and upon reboot it will no longer boot. It spins up and all lights come on for 1 second then powers down and cycles that process again in 3-4 secs. Now this did this a few days ago and I said "power supply". But then I had a 5yr old Corsair AX750 so I just installed a bran new AX860i and it's doing the same thing...arggg. Could be defective card but I just left the power cord out for a good 10 min. and it booted to windows again. I played around for a good half hour and decided to try sleep mode. Seems to get half way to going to sleep and freezes...dual monitors off but all fans still spinning. Won't wake up or complete sleep. 10 min. later I had to force shut it down and it's back to doing that boot cycle thing again. I just upgraded from dual 27" 1080 monitors to dual 32" 4k and figured the best thing I could do is upgrade my Radeon HD 7970 card...sucker ran mint for 3 years now I'm regretting this. Any ideas?

ohh and just to add to this. The PCIe power lines I do run 2 independent lines off the PSU. I mention that because for some reason Corsair sends out 2 forms of cables with the AXi series units. One set has a Y from a single line...I'd never wire a beast card like that. I used the set that is one connector per wire lead. So 2-8pins leads and I should be good for 300watts I believe. Power supply was not my issue.

Let me get this right you removed any old video card drivers that belonged to any Nvidia or Amd based graphics card in the system prior to buying the new 1080 GTX card yes ?

The GTX 1080 card worked and displayed a screen image when first fitted to the motherboard via one of it`s Pci-e graphic card slots of the motherboard.

Where you ensured that power directly from the Psu of the system was connected to the GTX 1080 card via the 12v Pci-e supplementary power connectors ?

And that you also ensured that the eight pin EPS or E-atx 12v connector was fully connected to the motherboard directly from the Psu`s connector block provided ?

Just confirm for me that all of the above was done or checked before you managed to get into windows...

OK there's some interesting boot options that might be related. Enable CSM and I'm reading about it but there's PCIe boot options and UEFI stuff in here...ya I'm back in after that long power disconnect thing that makes it work for whatever reason. When I was in windows I used GPU-z and saw an notice I did not see with my Radeon HD card. UEFI bios and I said you'd need CSM enabled to boot with this card...I don't remember the whole wording.

Win 7 x64 Pro. iGPU is disabled but using that defeats the purpose of getting this new card to run. I know the computer itself is fine as the Radeon HD 7970 has none of the issues I listed. It's hard for me to believe the 1080 card is defective when it will boot one minute and freezes trying to sleep or power cycles upon a restart. If I disconnect the PSU power cord for about 10 min it will boot again. It's as if once power level dies the card freaks.

I'll also add that I just got it to boot again but now my secondary monitor has a ton of multi colored vertical lines....ewww...maybe the card is toast.

Just confirm for me that all of the above was done or checked before you managed to get into windows os, and then install the Video driver for the GTX 1080 card you bought.

Please PM me, and I will give you a list of things to look for and setup with your system to get it booting and working with the GTX 1080 card fitted and the video driver also installed.
