I built a hackintosh that was running fine for over a year, then all of a sudden while I was waiting for a friend in a game lobby, the screen turned green. At one point it turned green, then pink (at least I think so, red-green color blind here), then black. Now it's stuck on green again. It's not my TV, and I'm inclined to believe it isn't my OS either (guy in this thread had a similar, unresolved issue on a windows ). I switched the video output to my mother board and the screen works so I'm inclined to believe it is definitely the card. I submitted a request for repair to EVGA, but if it's a fix I can do myself without the hassle of waiting for the warranty shipping and what not I'd like to do that!

So, has anyone had this issue before? Or know of a way to fix it? Is my graphics card dead??   

Thanks
 
 
 

ofc if you wish to be 100% sure... you can install Dual boot windows on this system and see if the card working fine there.
 
or use the card in another computer (if you don't have try friend's comp)
 
if you have none of this options ... then see my first post and ill need some info to try and help you out.

I can see the BIOS just fine, the issue doesn't occur until the OS (Yos 10.10.1) boots up. I did a fresh install, still got the green screen. 
 
Screen shot of what?
 
The MB is Gigabye z97x-ud5h-bk.
 
I don't have a way to install windows, and all my friends are console gamers, so I don't have a way to install it in another machine.

should have said it in another way. i meant photo the green screen with your cell phone and upload the photo here.
 
about the motherboard... some poeple had good success resolving this issue with flashing latest bios.
so, check if you are using the latest bios and if not flash it.
 
also i will look in to this and as soon as i have any info i'll get back to you.
i am sure it's software related.
what version of OS do you have ? EL capitan or ? 

also try to boot with nvda_drv=1 and -V if you didn't already.
 
 

I mentioned it in m last comment. Lol. Yosemite 10 10 1
 
Ill give those a shot now

I tried the first boot flags and it booted with the vcard seated. It froze after about two minutes, tried again, same boots and back to getting green screened.

Second set of boots gave me safe mode that I was able to see. (No green)

Aha !... so it's clearly not your card.
try downloading different drivers ... also, what did you use to set hackintosh up? chamilion . chimera , unibeast , multibeast and so on and so forth. give me some more info.
i will try to look into it more tomorrow... very Tired :( (can't see the monitor anymore so tired)

Well that's a relief then. I've used multi beast this entire time. None of the settings were ever changed once I got it running smoothly. This green screen occurrence was just out of nowhere.

And I'm not entirely sure which drivers to install without potential getting kernel panics.

Thanks so far!

I've had the screen go magenta tint every once in a rare while when the video card is attempting to initialize a resolution. My issue was on Windows 10 though. Also, my issue is on GTX980ti. I think sometimes the Nvidia driver is a bit flaky on initializing the card and something is out of sync in the signal. 95% of the time no issue though. Which port type are you using? Mine is HDMI.

@Saijin I've tried several different cables. Both HDMI and DVI, same issue.
 
@Brad I'm using HDMI. And its gone pink on me before, maybe it was magenta, again I'm colorblind lol. So I'm not 100% sure.
 
@lordaeron I tried some different drivers from the website, I also tried letting CUDA automatically update the driver for me. Still back to the green screen. I havent been able to get it working again with nvda_drv=1, other than those 2 glorious minutes :'(
And Im using multibeast BTW. I haven't found anyone else with this issue on a mac/hackintosh with this gtx760 model. Unless I just haven't looked deep enough x.x

sadly i won't be able to help in near 24 hours or so ... going to visit some one at hospital. :(
 
please take a look here : http://www.tonymacx86.com/
 
the guys at tony's will be able to help you sort the gpu driver out.  if your going to need more help after that let me know. sadly time is not on my side :S 

And it's okay I understand. It's still usable so I'm not in a HUGE rush. Thanks for the help so far!

No worries! Take care of what you need to. We can handle it when you've got some time.

i am getting a bit a head of myself here but . if what i wrote in post before this works use this :
 
Use MultiBeast -> Customization -> Boot Options -> GraphicsEnabler=No
or YES . depends what is going to work.

Graphicsenabler=yes gives me no signal

is there any chance you can install El- capitan by any chance ?
